Best Order Management Software in 2026: 15 Platforms for Multi-Channel Order Operations

Updated August 2026

The best order management software in 2026 depends on where your orders break, not on which vendor spends the most on category ads. Brightpearl leads for retail and wholesale operators who want a genuine retail operating system with accounting built in. Linnworks leads when the problem is listings and orders spread across a dozen marketplaces. Cin7 and Extensiv Order Manager lead when inventory accuracy across multiple warehouses and 3PLs is the actual constraint. ShipStation and Veeqo lead when the bottleneck is labels, rates, and carrier rules rather than stock. Sellercloud and NetSuite sit at the high end for high-volume sellers and finance-led enterprises. And Rework fits mid-size operators who want orders, inventory, invoices, and the customer record on one platform instead of four tools stitched together.

This guide ranks 15 platforms for ecommerce managers, ops managers, COOs, and founders running orders across a website, marketplaces, wholesale, and retail at once. Each one is judged on channel coverage, inventory sync behaviour, purchasing and replenishment, routing to warehouses and 3PLs, shipping, returns, and what the bill actually looks like once add-on modules and onboarding are counted. Every price below was checked against the vendor's own pricing page in August 2026, with monthly versus annual billing stated wherever the vendor publishes both, and where a vendor publishes nothing at all, this article says so plainly instead of dressing a third-party estimate up as a confirmed number.

Key Facts

• Inventory distortion, the combined cost of out-of-stocks and overstocks, ran to $1.73 trillion globally in 2025, roughly 6.5% of global retail sales, per IHL Group's inventory research.
• US shoppers were expected to return $849.9 billion of merchandise in 2025, 15.8% of annual sales, with an estimated 19.3% of online sales coming back, per the NRF and Happy Returns 2025 Retail Returns Landscape.
• Marketplace seller teams spend 36% of their working week, close to two full days, on manual updates such as fixing listings, updating inventory, and handling returns, per ChannelEngine's Marketplace Seller Trends Report 2025.
• Sellers now run an average of six marketplaces each, 34% are on seven or more, and 91% call automation business-critical, per the same ChannelEngine 2025 report.
• Without EPC-enabled RFID, 69% of orders shipped from brands to their retail partners contained data errors, against 99.9% order accuracy for those using it, per the Auburn University RFID Lab and GS1 US study of more than a million items.

What Order Management Software Actually Is (and What It Isn't)

Most people shopping this category are shopping three categories at once, which is why the shortlists get messy. An order management system sits between your sales channels and your fulfilment: it takes orders in from every channel, decides what stock can serve them and where they ship from, pushes them to a warehouse or 3PL, and closes the loop when they ship or come back as a return.

That is not the same job as a storefront platform, and it is not the same job as an inventory tool. If you are still choosing the storefront itself, the best ecommerce platforms roundup covers that decision, and the two most-searched storefront head-to-heads live at Shopify vs WooCommerce and BigCommerce vs Adobe Commerce. If your real gap is stock counts, reorder points, and multi-warehouse accuracy rather than order flow, the best inventory management software roundup is the closer fit.

The practical test is simple. If a customer cannot buy, that is a storefront problem. If you do not know how many units you have, that is an inventory problem. If an order landed in Shopify, the stock was actually at a 3PL, the marketplace listing did not decrement, and someone re-keyed the whole thing into a spreadsheet, that is an order management problem, and it is the one this list solves.

Quick Comparison Table

1. Brightpearl: A Retail Operating System, Not Just an Order Tool

Brightpearl is the closest thing this category has to a true retail operating system. Rather than bolting order management onto an inventory database, it runs orders, inventory, purchasing, supplier management, CRM, warehouse operations, and double-entry accounting as one product, with an automation engine firing rules on order events (fraud screening, order splitting, back-order handling, shipping-method assignment). For a retailer tired of reconciling a storefront, a stock tool, and an accounting package that never agree, that consolidation is the whole pitch.

The typical buyer is an established multi-channel retailer or wholesaler running a website plus marketplaces plus wholesale, already past the ceiling of spreadsheet reconciliation. Long-term users cite the Automation Engine and the accounting layer most often, since the latter removes an integration everyone else depends on.

Brightpearl does not publish a price. No plan names, no order thresholds, no minimums, no onboarding figure. The page states that pricing is bespoke and built per customer, and that unlimited users are always included at no extra cost, which is unusual in a category where per-seat fees are how most vendors scale a bill. Quoting happens through a demo request, so budgeting starts with a sales conversation. If Brightpearl is the incumbent you are moving away from rather than the one you are moving toward, the dedicated Brightpearl alternatives guide goes deeper on that specific switch.

Best for: Multi-channel retailers and wholesalers who want one system of record for orders, stock, purchasing, and the books. Not ideal for: Small sellers who need a published price to budget against before talking to anyone.

2. Linnworks: Channel Control for Sellers Living on Marketplaces

Linnworks solves the pain that sends most sellers looking for an OMS in the first place: too many channels, each with its own listing rules, each decrementing stock on its own schedule, none of them talking to the others. It aggregates orders from marketplaces, webstores, and social channels into one queue, keeps inventory synced back out, and manages the listings themselves rather than only the orders they generate. That listing depth is what separates it from the shipping-led tools further down this list.

The company sells two products. Linnworks Advanced is the end-to-end ecommerce operations platform, and SkuVault Core is the warehouse-focused product from the SkuVault acquisition. On top of the base platform, Listing, WMS, Enhanced Warehouse, and Forecasting are sold as add-on modules at extra monthly cost, which matters when you are comparing a Linnworks quote against a competitor's all-in tier.

Pricing is not published. Linnworks prices on monthly order volume rather than revenue, and states plainly that there are no percentage fees, ever, with tiered overages once you exceed your plan's order count. A one-off onboarding fee is calculated on your best-fit package and is not published either. You cannot budget Linnworks from the website, but the order-volume model is more predictable than a revenue percentage once the quote lands. Sellers weighing this against the rest of the field will want the Linnworks alternatives breakdown, which compares it tool by tool.

Best for: Multi-marketplace sellers who need listing control and order aggregation in the same tool. Not ideal for: A single-channel DTC brand that would pay for channel breadth it never uses.

3. Cin7: Inventory Accuracy First, Order Operations on Top

Cin7 comes at order management from the inventory side, which for many operators is the right entry point, because most order chaos is really stock chaos wearing a different hat. Cin7 Core (formerly DEAR) handles inventory, purchasing, manufacturing, B2B ordering, and multi-channel order sync, with one of the larger integration libraries in the category. Cin7 Omni sits above it for operations needing EDI, heavier channel management, and deeper warehouse workflows.

The tiering is where buyers need to read carefully, because Cin7 caps three things at once: users, annual sales orders, and integrations. Cin7 Core lists Standard at $349/mo for 5 users, 6,000 sales orders a year, and 2 integrations; Pro at $599/mo for 10 users, 24,000 sales orders a year, and 4 integrations; and Advanced at $1,199/mo for 15 users, 120,000 sales orders a year, and 6 integrations. All figures are USD and exclude taxes. Cin7's pricing page does not state whether those rates are billed monthly or annually, so treat them as list prices and confirm the billing cycle in writing before signing.

Cin7 Omni is quote-only, listed as contact us for pricing with 8 users and flexible order volume. The practical warning: a fast-growing business hits the order ceiling long before the user ceiling, so model the next twelve months of order count, not headcount. For a side-by-side against the field, see Cin7 alternatives, and for the head-to-head buyers ask about most, Cin7 vs Katana.

Best for: Growing operators whose order problems start with inventory accuracy across channels and warehouses. Not ideal for: Low-order-count sellers who would pay a $349/mo floor for capacity they will not use.

4. Extensiv Order Manager: Multi-Node Routing for DTC and 3PL Stacks

Extensiv Order Manager, which most operators still know by its original name Skubana, is the specialist pick for brands whose orders have to be routed intelligently across more than one fulfilment node. Where a simpler OMS assumes one warehouse, Extensiv assumes several: your own facility, two or three 3PLs, and Amazon FBA, all live at once, with routing rules deciding which node serves which order based on stock, geography, and cost. It also carries genuinely useful replenishment and profitability analytics, so buying decisions and channel-level margin sit in the same tool as the orders.

Extensiv fits established DTC and multi-channel brands, usually past a few thousand orders a month, that have outgrown a single-warehouse assumption and are juggling 3PL partners. It sits alongside 3PL Warehouse Manager and Integration Manager in Extensiv's wider platform, which is why it shows up on shortlists for brands whose fulfilment partners already run Extensiv.

Extensiv does not publish a price for Order Manager. It is sales-quoted only. And here is the trap worth naming explicitly: a $39 per month figure circulates widely for Extensiv, but it belongs to Extensiv Integration Manager, a different product entirely. Attaching it to Order Manager will give you a budget that is wrong by an order of magnitude. Ask for the Order Manager quote specifically, and confirm which modules are inside it.

Best for: DTC and multi-channel brands routing orders across several fulfilment nodes at once. Not ideal for: Single-warehouse sellers who do not need multi-node routing logic.

5. ShipStation: The Shipping Layer That Doubles as Order Triage

ShipStation is not a full OMS and does not claim to be, but it belongs high on this list because for a lot of sellers the thing actually breaking is shipping, not stock. It pulls orders in from storefronts and marketplaces, applies automation rules to assign services and packaging, buys discounted labels across a deep carrier roster, and pushes tracking back to the channel. For a team drowning in rate shopping, it fixes the visible problem in a week rather than a quarter.

Pricing is tiered by monthly shipment count, so a single starting price tells you almost nothing on its own. ShipStation's pricing page lists Starter from $14.99/mo at 50 shipments, rising to $174.99/mo at 5,000 shipments, with 3 users. Standard runs from $29.99/mo at 50 shipments up to $3,599.99/mo at 100,000 shipments, with 10 users. Premium runs from $349.99/mo at 50 shipments up to $7,499.99/mo at 100,000 shipments, with 15 users. Annual billing saves 20%, and there is a 30-day free trial. Always quote the tier and the shipment band together, because the same plan name spans a hundred-fold price range.

The honest limitation: ShipStation manages orders on their way out the door, not the inventory behind them, the purchase orders that replenish it, or wholesale order entry. Plenty of operators run it alongside an inventory platform from this list rather than instead of one.

Best for: Sellers whose bottleneck is buying and printing labels across many channels and carriers. Not ideal for: Operators who need inventory, purchasing, and wholesale order entry in the same product.

6. Rework: Commerce Operations on the Same Platform as the CRM

Rework's Commerce module runs order and commerce operations inside the wider Rework platform, which also carries Sales CRM, Lead, Inventory, Invoice, Product, Work Ops, and People. The argument is not that Rework has a better order screen than a dedicated OMS. It is that the order, the stock behind it, the invoice, and the customer who placed it all live on one platform, instead of a storefront synced to a CRM, an inventory tool, and an accounting package through three integrations that each break on their own schedule. Rework also runs a unified multi-channel inbox (WhatsApp, Messenger, Instagram DM, web chat, email, and SMS) on the same contact timeline, which suits social-commerce sellers and B2B teams who take as many orders over chat as through a cart.

Two honest limits, stated plainly because they matter more here than anywhere else on this list. Rework is not a storefront builder: no themed web storefront, no template gallery, no D2C checkout page of its own. It sits behind or beside a storefront, never in place of one. And it is not a warehouse execution system: no wave picking, no directed putaway, no scanner-driven bin logic of the kind Descartes Finale or a dedicated WMS provides. If your bottleneck is inside the four walls of the warehouse, a specialist belongs on the shortlist instead.

Rework does not publish a price for Commerce. It sells packages rather than per-user licences, and Commerce is quoted per organization. See rework.com/pricing or ask the team for a Commerce quote. If the CRM side is the more relevant evaluation, the best CRM software roundup covers that category in full.

Pricing: Quote on request. Best for: Mid-size operators (roughly 10 to 200 people) who want orders, inventory, and invoicing on the same record as the customer and the deal, rather than a storefront synced to three separate tools. Not ideal for: Rework is not a storefront builder and it is not a warehouse execution system. Teams needing a themed public storefront should pair it with one of the platforms in the ecommerce platforms roundup, and teams whose real constraint is scanner-driven warehouse work should look at a dedicated WMS.

7. Zoho Inventory: The Clearest Published Price Ladder in the Category

Zoho Inventory is the tool most often shortlisted by operators who want to know what something costs before booking a call. It covers multi-channel order management, stock across multiple locations, purchase orders, drop-shipping and back-orders, shipping integrations, and packing workflows, and plugs straight into Zoho Books and Zoho CRM, where most of its buyers already are.

The price ladder is published and specific. All paid tiers are billed annually: Standard at $29/mo for 500 orders a month, 3 users, and 2 locations; Premium at $79/mo for 3,000 orders, 5 users, and 4 locations; Plus at $129/mo for 7,500 orders, 10 users, and 6 locations; and Enterprise at $249/mo for 15,000 orders, 10 users, and 10 locations. There is a genuinely free tier capped at 50 orders, 1 user, and 1 location, useful for testing rather than for running a business. Add-ons are priced separately: extra users at $7.50/mo, an extra 500 orders at $7.50/mo, extra locations at $10/mo, and Advanced Warehousing at $124.17/mo.

The catch is the order ceiling. Five hundred orders a month sounds generous until a good campaign month blows through it and the overage add-ons stack. Model your peak month, not your average. For the wider field, see Zoho Inventory alternatives.

Best for: Small and mid-size sellers who want published pricing and are already using Zoho products. Not ideal for: High-order-volume sellers whose peak months would blow past the tier caps every quarter.

8. Veeqo: Free Shipping, Paid Inventory, and a Reputation Worth Correcting

Veeqo is the most misdescribed product in this category, so it is worth getting right. Amazon acquired Veeqo and made the shipping side free, and that has been flattened into a widely repeated claim that Veeqo is completely free. Half of that is true. The Shipping plan is genuinely free, with unlimited orders, users, products and SKUs, and warehouses, and Veeqo earns commission on the labels bought through it. That is a real offer, not a trial.

The inventory side is not free. Veeqo's pricing page lists an Inventory plan from $19/month and a High Volume plan from $350/month, both priced on monthly order volume. Orders fulfilled by Amazon through FBA or MCF are excluded from chargeable order volume, which materially changes the maths for Amazon-heavy sellers. So the accurate summary in any comparison is two-part: free to ship, paid to manage inventory, with the inventory rate depending on how many orders you push through it.

For a seller who is mostly on Amazon with light inventory needs, Veeqo is close to unbeatable on cost. For anyone needing deep purchasing, landed cost, or manufacturing logic, it is a shipping tool with an inventory add-on, and other tools here do that work properly.

Best for: Amazon-heavy multi-channel sellers who want free shipping software and light inventory control. Not ideal for: Distributors and manufacturers who need landed cost, batch tracking, or production logic.

9. Ordoro: Buy Only the Order Operations You Actually Need

Ordoro takes an unusual and useful approach: instead of one product with feature-gated tiers, it sells three separate apps and you subscribe to whichever match your problem. Shipping covers label buying, rate comparison, batch printing, and returns. Inventory covers multi-warehouse stock, purchase orders, kitting, and bill of materials. Dropshipping covers vendor routing, supplier notifications, and vendor portals, which almost nobody else here does as a first-class feature.

That modularity is why Ordoro shows up on shortlists with nothing else in common. A seller drowning in labels buys Shipping. A brand routing half its catalog through suppliers buys Dropshipping and skips the rest, then adds Inventory later without changing vendor.

Ordoro's pricing page reflects that structure. Shipping is free to start. Inventory is listed as starting at $349/mo. Dropshipping is listed as starting at $299/mo. Bundled pricing across all three apps is quote-only, so a business that wants the full stack needs a conversation rather than a checkout. There is a 15-day free trial with no card required. The honest read: the free shipping entry point is excellent, and the inventory and dropshipping floors put Ordoro in the same price band as Cin7 Core once you are buying more than one app.

Best for: Operators who want to solve one order-operations problem now and add the next app later. Not ideal for: Teams wanting one flat, fully published price for the complete platform.

10. Katana: When Sales Orders Have to Drive Production

Katana belongs on an OMS shortlist for one shape of business: you make what you sell, so the order problem is really a commitment problem. When an order lands, Katana allocates materials, schedules production, and shows in real time whether the promise you just made is achievable given current stock and shop-floor capacity. Most order tools treat production as a black box. Katana treats it as the thing the order depends on.

The buyer is a small to mid-size manufacturer, a made-to-order brand, or a batch producer in food, beverage, or cosmetics, usually selling through a Shopify or WooCommerce store plus wholesale, with sales orders, production orders, and purchase orders in one flow.

Katana's pricing page lists a Free plan at $0 covering up to 30 SKUs with unlimited users and unlimited sales orders, which is a real starting point for a very small maker. Core starts from $299/mo with unlimited users and SKUs, usage-based order pricing, and 1 location included. Three add-on modules are priced separately: Manufacturing Management at $199/mo, Traceability at $249/mo, and Warehouse Management at $149/mo. Advantage is custom, on an annual contract. An onboarding package costs $2,000, optional on Core and included on Advantage. Budget honestly: Core plus two modules plus onboarding is a very different number from the $299 headline. See Katana alternatives for how it compares against the rest.

Best for: Makers and light manufacturers whose order promises depend on production capacity. Not ideal for: Pure resellers and dropshippers with no manufacturing step at all.

11. inFlow: SMB Order Management With B2B Ordering Built In

inFlow is the pick for smaller wholesalers, distributors, and light manufacturers who need real order operations without an enterprise price tag. It covers sales orders, purchase orders, multi-location stock, barcode picking and receiving via a mobile app, and a B2B Showroom that lets trade customers order against agreed pricing. That last piece is the differentiator here, because most SMB tools leave wholesale ordering as someone's inbox problem.

inFlow publishes both billing cycles, which makes budgeting straightforward. inFlow Inventory lists Entrepreneur at $161/mo billed monthly or $129/mo billed yearly, covering 2 users, 1,200 sales orders a year, and 1 integration. Small Business is $436/mo monthly or $349/mo yearly, covering 5 users, 12,000 orders a year, and 3 integrations. Mid-Size is $874/mo monthly or $699/mo yearly, covering 10 users, unlimited orders, and 5 integrations. Enterprise is custom with 25 users and a required one-time onboarding fee of $499. Extra orders cost $0.20 each, and training or professional services run $199 an hour. There are also separate products: inFlow Manufacturing at $224, $561, or $1,124 a month billed monthly, or $179, $449, or $899 billed yearly; and inFlow Stockroom at $129/mo billed monthly or $99/mo billed yearly.

Read the order allowance carefully: inFlow counts sales orders per year, not per month, so the entry tier's 1,200 works out to roughly a hundred a month.

Best for: Small wholesalers and distributors who want sales orders, purchasing, and B2B ordering in one affordable tool. Not ideal for: High-volume ecommerce sellers whose order counts would trigger constant overage charges.

12. Unleashed: Costing and Traceability for Wholesale Distribution

Unleashed is built for businesses where the order is only half the story and the cost behind it is the other half. It covers landed cost calculation, batch and serial tracking, multi-warehouse stock, assembly, supplier management, and a B2B ordering portal, with reporting aimed at margin rather than channel analytics. For a distributor absorbing freight and duty into unit cost and tracing batches back to suppliers, that focus is exactly right.

Unleashed publishes both billing options separately, which is worth quoting carefully. Core is $399/mo billed monthly, or $4,389 per year billed annually, covering 3 users, 100 sales orders a month, 3 integrations, and 250,000 API calls a month. Pro is $729/mo billed monthly, or $8,019 per year billed annually, covering 5 users and 5 integrations. Note that the annual figures are yearly totals as Unleashed publishes them, not a discounted monthly rate.

The add-ons matter more here than almost anywhere else. Extra users cost $69/mo on Core and $89/mo on Pro. Sales-order upgrades are separate: $70/mo for 500 orders, $200/mo for 1,500, $320/mo for 3,000, $490/mo for unlimited. Modules sit on top: Advanced Inventory Manager $149/mo, WMS $149/mo, B2B eCommerce $129/mo, CRM $450/mo. Onboarding is a one-time $449 self-service, $799 standard, or $5,549 full. A realistic quote is the base tier plus at least one order upgrade plus onboarding.

Best for: Importers, wholesalers, and distributors who need landed cost and traceability alongside order management. Not ideal for: High-order-volume ecommerce sellers, where the order upgrades dominate the bill.

13. Descartes Finale: Barcode Operations at Serious SKU Counts

Descartes Finale, known for years as Finale Inventory before the Descartes acquisition, is the specialist for very large SKU counts and real barcode workflows across multiple warehouses. Where lighter tools get unwieldy past a few thousand SKUs, Finale stays responsive with tens of thousands, adding lot and serial tracking, mobile scanning for receiving, picking, and cycle counting, and multi-channel order sync feeding it all. It is what operators reach for when the warehouse floor, not the sales channel, is where errors happen.

Pricing has moved significantly, and this is worth stating clearly because outdated figures circulate widely. Descartes Finale's pricing page lists Essentials starting at $499/month, Growth starting at $799/month, and a custom Enterprise tier. Standard onboarding is included in the subscription, which offsets some of that entry price against competitors who charge implementation separately. The page does not state whether those are monthly or annual billing rates, so confirm the cycle before comparing. The old "from $99 a month" Finale entry price you may still see quoted in older reviews and listicles no longer exists.

The trade-off is scope. Finale is deep on warehouse and inventory operations and light on the commercial side: no CRM, no marketing, no ledger of its own. It is a strong component in a stack rather than the single system of record.

Best for: High-SKU, multi-warehouse operators whose accuracy problems live on the warehouse floor. Not ideal for: Small catalogs that would pay a $499 floor for scale they will never reach.

14. Sellercloud: Configurable Order Operations for High-Volume Sellers

Sellercloud aims at the top end of the multi-channel seller market: large catalogs across many marketplaces, with channel-specific pricing rules, kitting and bundling, shipping logic, and warehouse workflows too idiosyncratic for an off-the-shelf tier. Its reputation is configurability, and almost every part of the order lifecycle can be shaped to how a business actually works, including custom fields, custom workflows, and a companion warehouse app.

That flexibility is also the caveat. Configurable systems reward teams with the maturity to define what they want and the resources to build it. A small team without an operations lead can spend months configuring what a simpler tool would have handled on day one.

Sellercloud publishes a single figure and no tier ladder: starting at $1,349 per month, footnoted as an annual subscription based on order volume and add-ons. That is the highest published entry price in this roundup, and the footnote is the important part, because the actual quote moves with your order volume and which modules you take. Treat $1,349 as a floor rather than a price.

Best for: High-volume multi-channel sellers with rules that off-the-shelf tiers cannot express. Not ideal for: Smaller sellers without the operational capacity to configure and maintain it.

15. Oracle NetSuite: Order Management Inside a Full ERP Ledger

NetSuite is where this list ends, because past a certain size the order management question becomes a financial systems question. NetSuite runs orders, inventory, procurement, warehouse management, and demand planning as modules inside a full cloud ERP, sharing one ledger with financials, revenue recognition, and multi-subsidiary consolidation. For a company across several entities, currencies, and regions, that single ledger is the reason to buy, and no dedicated OMS here replaces it.

The buyer is finance-led as often as operations-led. NetSuite is usually chosen by a CFO who needs consolidated reporting across entities, with order management arriving as part of the platform rather than as the driving requirement.

NetSuite publishes no price. Per NetSuite's own material, the annual licence is built from the core platform, plus whichever optional modules you take, plus the number of users, with a separate one-time implementation fee on top. Implementation is a project measured in months, not weeks. Any specific dollar figure you find attached to NetSuite online is a third-party estimate, not an Oracle-confirmed number, and the range is wide enough to be useless for planning.

Best for: Multi-entity enterprises that need order management sitting inside a consolidated financial system. Not ideal for: Single-entity operators who need orders fixed this quarter, not next year.

Also Worth Knowing

Four more tools come up often in OMS shortlists without quite belonging in the numbered list above, plus one that should stop coming up at all.

If you are still seeing QuickBooks Commerce on a shortlist, that shortlist is at least three years stale. Most of its users moved to Cin7, Katana, or Fishbowl depending on whether their problem was channels, production, or QuickBooks proximity, and the Fishbowl alternatives guide covers that last group in detail.

Stage Fit: What to Buy at Each Point of Growth

The right OMS changes as the operation changes. This is the shape most sellers actually move through.

Sizing and Persona Fit

Who signs the contract usually tells you which tool wins, because each of these is built around a different job title's daily pain.

Pricing at a Glance

Half the confusion in this category comes from comparing a monthly rate against an annual one. This table restates each vendor's published entry price with the billing basis they publish it on, so nothing here is derived.

How to Choose: Decision Framework

Start from the constraint that will still be true in two years, not the feature that annoys you this week.

What to Do Next

Pick two tools of different shapes rather than two versions of the same thing: one matching where your orders break today, one built for the operation you expect in two years. Then run the same test on both. Import a real week of orders across every channel you actually sell on, not a demo set. Push one order end to end including a split shipment, a back-order, and a return. Then add up the true annual cost: subscription, onboarding, per-user fees, order overages, and any module the demo quietly assumed you would buy.

If the shortlist still feels wide, name your constraint out loud. Labels and carrier rates point to ShipStation or Veeqo. Channel and listing sprawl points to Linnworks or Sellercloud. Stock accuracy points to Cin7, Descartes Finale, or Unleashed. Routing across nodes points to Extensiv or Brightpearl. And if the honest answer is that orders, stock, invoices, and customer conversations live in four disconnected systems, that is a consolidation problem rather than an OMS feature gap, and worth settling before you sign anything.
