Best enterprise ecommerce platform for retailers in 2026
Seven platforms for chains with stores: POS, order management, B2B, marketplace, contracts and the full cost.
The short answer: pick Shopify Plus if you run stores and want a price you can read before the first sales call. Pick Salesforce Commerce Cloud if you need one order management system across 25+ stores and several banners. Look at Adobe Commerce or commercetools if your B2B or custom logic won't fit a standard SaaS. For a retailer, the license is rarely the biggest line. The integrator, the order management system (OMS) behind buy online, pick up in store (BOPIS), the POS and the contract terms weigh more. We compared seven platforms on that full picture, including the three support deadlines that are forcing replatforming projects in 2026.

Scores on five criteria weighted for a retailer with stores. Prices from official US pricing pages in 2026, before taxes, payments, apps and integration work. No third-party estimate is shown as a price.
How we compared and scored
What makes an ecommerce platform "enterprise"? Four things: several sites, countries and banners on one back office; B2B for franchisees or trade accounts; store operations (stock, POS, OMS); and a negotiated contract, often indexed on gross merchandise value (GMV, your total sales). We scored these platforms on the questions a retailer with stores asks in an RFP, not on feature lists. Who handles store stock and BOPIS: the platform or a separate OMS? Can franchisees or trade accounts order on the same site? What's published, what's a custom quote, and which clauses can raise the bill later? For each platform we read the official pricing pages, edition sheets, contract terms and support calendars, then merchant and developer threads to find what the sales deck leaves out.
When a vendor doesn't publish a price, we write "custom quote" and list the levers that move it. We don't turn third-party estimates into prices. Store operations carry the most weight, because that's what separates a chain from a pure online brand. If you mostly sell your own brand online, our ranking for DTC brands fits better, and the general ecommerce platform ranking compares platforms for every store size. Oracle Commerce, Elastic Path and Kibo Commerce aren't ranked this year: our research didn't gather enough official pricing and product facts to score them fairly.

Shopify Plus
Shopify Plus takes first place for a retailer with stores for a simple reason: it's the only platform here that publishes both a subscription price and an in-store price. Plus costs $2,500 a month on a one-year term, or $2,300 a month on a three-year term: $30,000 or $27,600 a year (our math). POS Pro, the store version of Shopify's point of sale, is included on the first 20 locations of any Plus contract. Its cost is waived on up to 200 retail locations if Shopify Payments is your main in-store processor. (The $89 per location you'll see on the pricing grid applies to the Basic, Grow and Advanced plans.) One back office manages up to 200 locations, stores and warehouses included. On top of that you get 9 expansion stores for other countries or banners and 25 headless storefronts (sites built separately and plugged into Shopify). B2B catalogs for franchisees or trade accounts are unlimited. Shopify's separate Enterprise offer advertises unlimited retail locations.
The subscription isn't the whole bill. Shopify says the price covers "standard setups and integrations": development, themes and apps come on top. There may also be a variable platform fee based on your revenue and business model, and it differs for B2B and direct-to-consumer sales. Neither the rate nor the threshold is published. Card processing starts at 2.25% + 30¢ online and 2.3% + 10¢ in store, premium cards cost 2.95% + 30¢, and a third-party payment provider adds 0.2%.
The weak spot for a chain is stock across separate stores. Expansion stores don't share inventory natively. Merchants sync them with apps, and a lag of a few minutes is enough to oversell a popular item. Custom checkout logic needs a check too: Shopify Scripts stopped running in 2026, replaced by Functions, and a Shopify staff member has acknowledged gaps on some discount stacking rules. Worth knowing: your payment choice decides the POS bill. A 100-store chain that takes in-store cards through Shopify Payments pays nothing for POS Pro. On another processor, only 20 locations are included, so get the price of the other 80 in writing.
- Published price: $2,300 to $2,500/mo
- Up to 200 locations from one back office
- Unlimited B2B catalogs and 9 expansion stores
- Enterprise page: 40,000 checkouts started per minute
- ✓Only platform here with public subscription and POS terms
- ✓Stores, online and B2B in one admin
- ✓Unlimited staff accounts, no seat math
- ✗Variable platform fee: rate and threshold not published
- ✗No native shared stock between expansion stores
- ✗99.9% uptime is an Enterprise-page figure, not a contractual SLA
The safest default for a US chain that wants stores and online on one platform and one readable budget line. Get the variable fee in writing, and plan the inventory layer before you add a second banner.
Salesforce Commerce Cloud
Salesforce Commerce Cloud is the reference for large omnichannel retailers, and its editions read like a chain's org chart. B2C Commerce Plus and Premium run up to 100 sites and 3,500 price books. Premium adds full Order Management and Data Cloud with 500,000 credits. Order Management Growth handles omnichannel inventory across up to 50 locations, with distributed order management, the engine behind ship-from-store and buy online, pick up in store (BOPIS). Retail Cloud POS starts at 25 stores. You can bring your own Adyen account for payments.
Every edition says "contact for pricing", in every currency. On B2B, Salesforce does state the model: a percentage of gross merchandise value (GMV), counted only on the storefront. Orders from stores or other channels go through Order Management, which is billed separately. Salesforce publishes no B2C rate, so don't anchor on the percentages you'll see in roundups. Ask for the rate, the GMV definition and the minimum in writing.
It's not a mid-market tool. A developer with eight years on the platform put the floor at about $5 million in annual sales: below that, Commerce Cloud "doesn't make sense". The same developer flagged a thin built-in CMS, so plan a content tool around it. At the other end, Carrefour runs Commerce Cloud alongside its existing platform to absorb peaks: traffic in Italy jumped tenfold during the first wave of the pandemic. Before the RFP: if you sell B2B and in store, price both lines. Storefront GMV is one bill, and the OMS that routes store orders is another.
- Up to 100 sites and 3,500 price books (Plus, Premium)
- Order Management across up to 50 locations
- Retail Cloud POS from 25 stores
- Bring your own Adyen account
- ✓Strongest store and OMS offer in this ranking
- ✓Built for many banners, sites and countries
- ✓B2B GMV counted on the storefront only
- ✗No public price in any edition
- ✗Needs certified developers or a partner
- ✗Thin built-in CMS
The pick when 25+ stores, several banners and one order management system drive the decision. Under about $5 million in online sales, the cost and the team it needs are hard to justify.
Adobe Commerce
Adobe Commerce (formerly Magento) is the pick when your rules won't fit a standard SaaS: negotiated B2B prices, custom checkout steps, deep ERP links. On the self-hosted edition you can change anything in the code. The open source version, Magento Open Source, has no license fee at all.
2026 is a deadline year. Each 2.4.x version gets three years of standard support. Versions 2.4.4 and 2.4.5 reach the end of extended support in 2026, then get security patches only until 2027. Version 2.4.6 reaches the end of standard support in 2026, keeps extended support until 2027, then gets security patches only until 2028. Adobe's recommended long-term destination is Adobe Commerce as a Cloud Service (ACCS), a "versionless" SaaS that Adobe updates for you. The catch: you can't modify core code, customizations get rewritten in App Builder, the storefront moves to Edge Delivery Services and the Luma theme isn't supported. Adobe itself calls the move a "full platform re-architecture", and data from third-party extensions doesn't migrate automatically.
Read the contract line by line. The on-premise terms we read (the 2019 version) let Adobe measure your GMV and your average order value (AOV). If GMV goes over a set threshold, or AOV drops under one, Adobe can adjust your fees. The same terms cap you at 15 store views, and count GMV without shipping, taxes or financing fees. A former tech lead at a retailer on Magento 2 described a six-figure annual license, plus hundreds of thousands of dollars spent stabilizing the platform. One trap: a season of deep discounts or low-ticket items lowers your AOV, so find the AOV threshold in your order form before you plan one.
- Full code control on the self-hosted edition
- ACCS removes version upgrades
- Open source edition with no license fee
- ✓Most room for custom logic in this ranking
- ✓Clear support calendar for each version
- ✓A SaaS route exists (ACCS) if you want out of upgrades
- ✗No public price
- ✗2.4.4 to 2.4.6 lose standard or extended support in 2026
- ✗AOV floor clause in the on-premise terms
Right for retailers whose B2B or checkout rules are the business, and who have the team to own them. If you're on 2.4.6 or older, price the ACCS rewrite against a full RFP before you renew.
commercetools
commercetools is the composable option. You get commerce as APIs, and you pick the front end, search and content tools separately: that's what "headless" means. More than 500 enterprises use it, including Sephora, John Lewis, JD Sports, Specsavers and Screwfix. Its pricing model stands out: it's based on orders, not on GMV, so a higher average basket doesn't raise your bill. You can buy it through AWS Marketplace or Google Cloud Marketplace, which is handy if your procurement already runs through one of them.
No price is public. Checkout, B2B APIs and extra regions are paid options. Premium support comes with an "enhanced SLA", but the number isn't published, so ask for it. The license is only part of the bill. You'll pay a team or an integrator to build and run everything around it, and few practitioners share their commercetools experience publicly. Reference calls matter more here than for any other platform on this list.
Field tip: the 60-day free trial needs no card and opens the full APIs and the Merchant Center, the back office. Use it to build a working prototype of your hardest flow (B2B pricing, a split order) before you write the RFP. Two limits: InStore, the module for stores, isn't in the trial, and nothing switches to production automatically.
- Priced per order, not on GMV
- 60-day free trial, no card
- Sold through AWS and Google Cloud marketplaces
- ✓Your bill doesn't grow with your average basket
- ✓Pick each layer of the stack
- ✓Prototype your hardest flow before you sign
- ✗No public price, SLA number not published
- ✗Needs a strong tech team or integrator
- ✗Store module (InStore) not in the trial
Powerful if you have the engineers, expensive in people if you don't. Prototype first, then budget the team before the license.
BigCommerce
BigCommerce has the lowest published entry price in this ranking. Performance starts at $1,499 a month billed annually, aimed at businesses with $1M+ in annual sales. That's $17,988 a year (our math), before apps, agency and payments. Price Lists, which set B2B prices per customer group, are a Performance feature. Multi-storefront is quoted separately. Under contract, the fee on an outside payment provider is 0%, and BigCommerce's own card rates start at 2.89% + 29¢.
Know the trigger. If you're on a standard BigCommerce plan and your GMV passes $2M over the trailing 12 months, you're moved to Performance automatically. Budget for it before it happens, not after the invoice. Above that level, BigCommerce Enterprise is priced on your projected sales volume and integrations, and BigCommerce promises "no proprietary penalties". Ask what Enterprise adds on top of Performance for your volume: the public pages don't list it.
Its limit for a chain: we found nothing about POS or store inventory on its pricing pages. Ask early how a BOPIS order and store stock would work, and which partner handles them. If you're close to $2M on a standard plan, negotiate the Performance contract yourself before the automatic switch, so you choose the term instead of inheriting it.
- Published entry price: $1,499/mo billed annually
- Price Lists for B2B customer groups
- 0% fee on outside payment providers under contract
- ✓Readable entry price for a mid-size budget
- ✓Freedom to choose your payment provider
- ✓B2B pricing from Performance
- ✗Automatic move from a standard plan to Performance at $2M GMV
- ✗Multi-storefront on quote
- ✗Store side (POS, store stock) not on its pricing pages
A sensible step up for a retailer outgrowing a standard plan, with a price you can budget. For a store-heavy chain, the store side needs its own answer.
SAP Commerce Cloud
SAP Commerce Cloud is the cloud edition of SAP's commerce platform, the product long known as Hybris. It makes sense mainly for retailers already on SAP: one vendor for ERP and commerce, and partners who know both sides. For a chain, the useful part is order management: SAP's own training lists central order management with split orders, backorders and pre-orders. It also lists returns and exchanges unified across channels, ship-from-store, and a headless storefront (Composable Storefront) connected through APIs. Its price isn't public, and this isn't a light project. Developers who built on Hybris have long said that a seven-figure budget to launch a tier-one platform was not unusual.
The 2026 deadline concerns the on-premise version, not the cloud edition ranked here. SAP Commerce 2205 is the last release you can host on your own servers, and its mainstream maintenance ended in 2026. What follows is Customer Specific Maintenance: no new fixes and no legal changes. If you still run Hybris on-premise, a project is coming either way: move to SAP Commerce Cloud, or replatform to something else.
Use the deadline: put it in the business case for your RFP. A forced migration is the right moment to compare SAP Commerce Cloud with Salesforce, Shopify Plus or commercetools on equal terms, instead of renewing by default. If the project can't start right away, price third-party support for the gap.
- Central order management: split orders, backorders, pre-orders
- Cross-channel returns and exchanges, ship-from-store
- Headless Composable Storefront, connected through APIs
- ✓Fits an existing SAP landscape
- ✓Buy online, exchange in store: returns unified across channels
- ✓Natural landing spot for on-premise 2205 customers
- ✗No public price
- ✗If you're still on-premise, a migration is now unavoidable
- ✗Heavy budgets and long projects
Logical if SAP runs the rest of your business. If you're still on on-premise 2205, treat the forced move as the start of an RFP, not a renewal.
VTEX
VTEX sells one platform for D2C, B2C, B2B and marketplaces, with omnichannel operations built in. That's its edge: if you want to open your site to third-party sellers, the marketplace is native rather than a second product. VTEX claims 3,500+ enterprise customers in 43 countries and more than $15B in GMV processed each year. Carrefour Brazil moved to VTEX in five months and reports a 30% lift in order conversion (VTEX's figures).
It ranks last here for a US retailer for two reasons. First, no price and no SLA appear on its site. Ask whether you'll pay a flat subscription, a share of GMV or both, and get the minimum in writing. Second, the main retail case we could read on its official pages is Carrefour in Brazil. Ask for references in your market and your vertical.
In-store pickup is documented. Each store is set up as a franchise account, a white-label seller of the main account, and pickup shows up as a delivery option at checkout. VTEX only offers a pickup point when stock is available, within 50 km (about 31 miles) of the customer's address, among the 300 closest points. POS is less documented, so ask for a demo of that flow.
Before you shortlist it: if a marketplace is the main reason you're looking at VTEX, run the comparison the other way too. Price Mirakl on top of the platform you already have, then decide whether a full replatform is worth it.
- Native marketplace and B2B portals
- 3,500+ enterprise customers in 43 countries
- $15B+ in GMV processed a year
- ✓Marketplace without a second vendor
- ✓B2B, B2C and D2C on one platform
- ✓Five-month migration on its showcase case
- ✗No public price or SLA
- ✗Few readable US retail references
- ✗Pricing model to clarify in writing
Worth a look if a marketplace is central to your plan. For a US chain without that need, the leaders above are easier to reference and to price.
What you can price, and how to choose
What can you actually price before an RFP? Not much. Here's everything the vendors publish, with our math, and what drives the custom quotes.
- Shopify Plus: $2,300 a month on a three-year term ($27,600 a year) or $2,500 on one year ($30,000 a year), before any variable platform fee, payments, apps and agency work.
- Shopify POS Pro on Plus: included on the first 20 locations, and free on up to 200 if Shopify Payments is your main in-store processor. A 100-store chain on Shopify Payments pays $0 for POS Pro; on another processor, ask for the price of the 80 locations beyond the 20 included.
- BigCommerce Performance: from $1,499 a month billed annually, so $17,988 a year, before apps and payments.
- Salesforce, Adobe Commerce, SAP, commercetools, VTEX: custom quote. The levers are your GMV or order count, the number of sites and storefronts, stores and inventory locations, B2B versus D2C, options (OMS, POS, extra regions, premium support) and the length of the term.
GMV-based pricing has a simple break-even. If your contract is at 1% of GMV, it costs as much as Shopify Plus at its three-year rate ($27,600 a year) at $2.76M in online sales. At 0.5%, the break-even is $5.52M. Against the one-year rate ($30,000), it's $3M and $6M (our math). No vendor here publishes a 1% rate: run the formula with the rate you're quoted, and add the integrator and the yearly run cost, which often outweigh the license.
You run 25+ stores across banners
You want stores and online on one budget line
You sell to franchisees, dealers or trade accounts
You want third-party sellers on your site
Your platform reaches end of support in 2026
You sell $1M to $5M online
- Put your volumes and channels in the RFP: online GMV, order count, average order value, stores, inventory locations, B2B accounts, countries and banners. Every quote is built on them.
- Map the systems the platform must connect to: ERP, POS, OMS, product information (PIM).
- Add the support end date of your current platform to the business case.
- Ask each vendor for a price per lever, an SLA as a number, the data hosting region and two references of your size.
- Ask each integrator for the yearly run cost after launch, not just the build.
- Price the OMS and the POS as their own lines, separate from the storefront license.
Eight checks that protect your contract
The clauses and traps that never make it into vendor decks. Each one comes from an official contract, pricing page or merchant experience.
The checks
Get Shopify Plus's variable fee in writing
Shopify PlusShopify says a variable platform fee may apply, based on your revenue and business model, and that it differs for B2B and D2C. It publishes neither the rate nor the threshold. Ask for both, for each channel, in the order form. Then compare terms: $2,500 a month on one year against $2,300 on three, a $7,200 gap over three years in exchange for the longer lock-in.
- Published
- $2,500/mo (1 year), $2,300/mo (3 years)
- Not published
- Variable fee rate and threshold
Find the AOV floor in an Adobe on-premise contract
Adobe CommerceThe on-premise terms we read let Adobe measure GMV and average order value, and adjust fees if GMV passes a threshold or if AOV falls under one. Most buyers watch the first trigger and miss the second. A promotion-heavy season or a shift to low-ticket items can lower your AOV. Find the number in your order form, and negotiate it before you plan the season.
- Triggers
- GMV above, or AOV below, a threshold
- Store views
- 15 maximum
Ask what counts as GMV on Salesforce
SalesforceOn B2B, Salesforce counts GMV on the storefront only. That sounds generous until you route store or other-channel orders: they go through Order Management, billed separately. Ask for both lines in the same quote, with the volumes of each channel, so the total doesn't move after go-live.
- B2B model
- % of storefront GMV
- Billed separately
- Order Management
Plan for BigCommerce's automatic upgrade
BigCommerceOn a standard plan, when GMV passes $2M over the trailing 12 months, BigCommerce moves you to Performance automatically. If you're close, negotiate the Performance contract before the switch. You choose the term and the start date instead of finding out on an invoice.
- Trigger
- $2M GMV, trailing 12 months
- Performance
- From $1,499/mo
Prototype on commercetools before the RFP
commercetoolsThe 60-day trial needs no card and opens the full APIs and the Merchant Center. Build your hardest flow (a B2B price, a split order) and show it to your integrator candidates. It turns a slide-deck RFP into a technical one. InStore isn't in the trial, and the sandbox never goes live by itself.
- Trial
- 60 days, no card
- Excluded
- InStore
Test every migrated Shopify discount twice
Shopify PlusShopify Scripts no longer run in 2026, and merchants report that the old logic "silently disappears" instead of failing loudly. Test each rule you rebuilt in Functions with two carts: one that should trigger it and one that shouldn't. Keep a copy of the old Scripts code, and check discount stacking first: that's where a Shopify staff member has acknowledged gaps.
- Scripts
- Stopped in 2026
- Replacement
- Shopify Functions
Protect shared stock across stores and banners
InventoryWhen separate stores sync inventory through apps, a lag of a few minutes is enough to sell the same item twice. Merchants who run several stores keep a safety stock of 5 to 10% per store, use a single source of truth for quantities, and set the sync to subtract only. It costs a few sales on the last units and saves the oversell refunds.
- Safety stock
- 5 to 10% per store
- Sync rule
- Subtract only
Get the data region and sub-processors in writing
ContractIf you sell abroad, don't assume a regional offer covers commerce. Shopify has said that storing data in one specific region isn't a native feature. Salesforce's EU Operating Zone keeps data in the EU and Switzerland, but Commerce Cloud isn't on its list of covered products. Ask every vendor for the hosting region and the list of sub-processors, in the contract.
- Shopify
- No native region choice
- Salesforce EU zone
- Commerce Cloud not listed

Enterprise ecommerce platforms · FAQ
How much does an enterprise ecommerce platform cost?
Only two vendors in this ranking publish a starting price. Shopify Plus costs $2,300 a month on a three-year term ($27,600 a year) or $2,500 on one year ($30,000 a year). BigCommerce Performance starts at $1,499 a month billed annually ($17,988 a year). Salesforce, Adobe, SAP, commercetools and VTEX quote on your GMV or order count, sites, stores and options. The license is rarely the biggest line: ask every integrator for the yearly run cost, not just the build, and add payments, apps and the OMS.Is Shopify Plus enterprise-ready for a retailer with stores?
Yes for most chains, with two checks. Plus manages up to 200 locations from one back office. Shopify's enterprise page advertises 40,000 checkouts started per minute before queuing; ask Shopify to confirm that figure for your Plus contract. Across all its merchants, Shopify reported a peak of $5.1M in sales per minute over Black Friday Cyber Monday 2025 (its own, unaudited figures). The checks: separate expansion stores don't share inventory natively, and the variable platform fee isn't published.Salesforce Commerce Cloud or Adobe Commerce: which fits a large retailer?
Salesforce if stores and order management drive the decision, Adobe Commerce if custom B2B rules and code control do. Salesforce sells Order Management across up to 50 locations and a POS from 25 stores, but you don't touch the core. Adobe gives you the code, but versions 2.4.4 to 2.4.6 lose standard or extended support in 2026, and its SaaS route means rewriting customizations in App Builder.SaaS, open source or composable: which architecture fits an enterprise retailer?
SaaS if you want the vendor to run upgrades and uptime, self-hosted if you must change the core, composable if you have the engineers to assemble the stack. Even Adobe now points customers to a versionless SaaS (ACCS) as the long-term destination. Composable (commercetools) costs the most in people: budget the team before the license.What happens now that SAP Commerce on-premise and older Adobe Commerce versions are out of support?
Your store keeps running, without the safety net. SAP Commerce 2205 on-premise moved to Customer Specific Maintenance in 2026, with no new fixes or legal changes. Adobe Commerce 2.4.4 and 2.4.5 get security-only patches until 2027; 2.4.6 keeps extended support until 2027, then security-only patches until 2028. Start the RFP now: a migration under deadline pressure is the worst moment to negotiate.How long does an enterprise replatforming take, and how do you avoid losing sales?
Count months, and more than a year for a full rebuild. Vendors showcase five-month migrations: a French apparel chain with 50+ stores moved off Magento 1 to Shopify Plus in five months, and Carrefour Brazil moved to VTEX in five. Agencies describe large projects of 18 to 24 months, repeated every three to five years, and phased migrations of three to five months per phase. To protect sales, move one country or banner first and run old and new sites side by side on that pilot. Redirect every old URL. And list the data that won't migrate on its own: third-party extension data when moving to Adobe's ACCS, discount logic from old Shopify Scripts.Do I need an OMS for buy online, pick up in store and ship-from-store?
Usually yes once several stores share stock. The OMS decides which store or warehouse serves each order, and the storefront only displays the result. An integrator who has run large Shopify implementations describes pairing it with many different order management systems. On commercetools, the store module (InStore) isn't even in the free trial, so plan that layer separately. Decide who owns stock before you pick the storefront.Can one platform run B2B and B2C?
Yes on most of this list, but check the edition limits, not just the feature. Salesforce B2B Commerce Growth covers 6 storefronts and Advanced 10, both with 20 inventory locations, and it's billed apart from the B2C editions. On Shopify Plus, B2B sits in the same admin as your D2C store, but its variable fee is set separately. Ask for B2B pricing as its own line in every quote.Can I try an enterprise platform before I sign?
Only partly. commercetools offers a 60-day free trial with no card, full API access and its Merchant Center; InStore isn't included, and nothing goes live automatically. Shopify's Plus pricing page shows a "Try for $399" button: ask what that paid trial covers before you count on it. For the others, write a scripted demo on your own data and your hardest flow into the RFP, so every vendor answers the same test.
