An eCommerce platform is the base software a company builds and runs its digital commerce on: catalog, cart, checkout, payments, order management and integrations with ERP, OMS and PIM. In 2026 they differ along two axes: architecture (monolithic, SaaS or composable/MACH) and the segment they serve best (mid-market or enterprise). Choosing the right platform is the most expensive technical decision to reverse in an entire commerce project.
This guide compares six serious platforms for companies in Mexico and LATAM, organized into two tiers. It is not a ranking. There is no "best platform": there is the best one for your vertical, your volume, your current stack and your technical capacity. The same platform that is brilliant for a high-volume B2C retailer can be unnecessary weight for a D2C brand just starting out.
The comparison covers architecture, what each one is strong at, where it limits you, the investment range and when to choose it. At the end there is a decision framework and a frequently asked questions section. All investment figures are market orders of magnitude; the final number always depends on the scope of your implementation, not just the license.
How to read this comparison: two tiers
We split the platforms into two groups because they compete in different leagues. Comparing them all in a single flat table confuses more than it clarifies.
- Tier 1 · Enterprise. Platforms for large, complex operations: massive catalogs, multi-country, deep ERP integration, corporate governance. More power and higher total cost of ownership (TCO), with longer implementations.
- Tier 2 · Mid-market / SaaS. SaaS platforms that deliver enterprise capabilities with far less overhead: fast time-to-market, less maintenance, vendor-managed. The sweet spot for most mid-sized companies.
Architecture (monolithic, SaaS or composable) is a column within each tier, not the grouping criterion. A composable platform like commercetools lives in enterprise because of its TCO and technical demands, not just its architecture.
Tier 1 · Enterprise
| Platform | Architecture | Strong at | Limitation | Typical investment | When to choose it |
|---|---|---|---|---|---|
| commercetools | Pure composable / MACH | Total flexibility, B2B + B2C + D2C, API-first, global scale | High cost, requires a strong technical team, no frontend included | License from ~US$40K/year + implementation US$60K–400K+ | Enterprise that needs maximum flexibility and has (or hires) a technical team |
| Salesforce Commerce Cloud | Suite (+ composable storefront) | Salesforce ecosystem (CRM, Marketing), robust B2C, Einstein AI | Percentage-of-GMV model, lock-in, less flexible than pure composable | High (typically % of GMV) | You already run on Salesforce and your B2C is high volume |
| SAP Commerce Cloud | Suite / monolithic | Complex B2B, native SAP ERP integration, massive catalogs | Heavy, expensive, long implementation, less agile | Very high (enterprise license + implementation) | You already run SAP ERP and your B2B is complex enterprise |
commercetools
The composable standard and a founder of the MACH Alliance. It is not a store you switch on: it is a set of commerce APIs (products, carts, orders, prices) you assemble with the frontend and services you choose. Its strength is flexibility with no ceiling and the ability to serve B2B, B2C and D2C on a single backend, at global scale. Its real cost is not the license but the team (internal or partner) that operates it. Choose it when your five-year ambition justifies building to fit and you have engineering muscle.
Salesforce Commerce Cloud
The natural choice if your company already lives in the Salesforce ecosystem (Sales Cloud, Marketing Cloud, Service Cloud). It is strong in high-volume B2C, with personalization and AI (Einstein) built in and a modern composable storefront. The trade-off is the price model tied to a percentage of GMV, which scales with your sales, and a degree of lock-in to the ecosystem. It makes sense when the synergy with the rest of your Salesforce stack outweighs the freedom to compose freely.
SAP Commerce Cloud
The workhorse of complex enterprise B2B, especially where SAP already runs as the ERP. It shines with massive catalogs, deep business rules, sophisticated per-customer pricing and native integration to the SAP backbone. The price is weight: high enterprise licensing, long implementations and less agility to iterate. Choose it when your B2B operation is large and dense and integration with SAP ERP is a requirement, not a plus.
Tier 2 · Mid-market / SaaS
| Platform | Architecture | Strong at | Limitation | Typical investment | When to choose it |
|---|---|---|---|---|---|
| VTEX | Composable SaaS (LATAM leader) | Unified commerce (native OMS + marketplace), B2B + B2C, local MX/LATAM payments, fast | Less control than pure composable, smaller global ecosystem than Shopify | Percentage-of-GMV model, mid-to-enterprise | You operate in LATAM and need a native marketplace/OMS with enterprise muscle in SaaS |
| BigCommerce | SaaS + Open SaaS (headless via API) | Native B2B (B2B Edition), no transaction fees, flexible headless, good cost | Fewer apps than Shopify, personalization limited vs composable | Enterprise custom (~US$1K–15K/mo based on GMV) + implementation | Mid-market B2B that wants SaaS with a headless option without enterprise cost |
| Shopify Plus | SaaS + Hydrogen (headless) | Speed, huge app ecosystem, best-in-class checkout, D2C/B2C | Less robust B2B (improving), fees if you do not use Shopify Payments, less flexible in complex logic | From ~US$2,300/month + implementation | D2C/B2C that prioritizes speed and a not-ultra-complex catalog |
VTEX
The most widely adopted platform in LATAM and one of the reasons Mexico has such a mature digital commerce ecosystem. Its differentiator is unified commerce: native OMS and marketplace, B2B and B2C on the same backend, and first-class support for local payments and logistics. It is SaaS, so the vendor manages the infrastructure, with composable options when you need them. Choose it when you operate in the region, want enterprise capabilities without the overhead of commercetools and value time-to-market.
BigCommerce
The most underrated SaaS for mid-market B2B. Its B2B Edition ships company catalogs, customer-specific pricing, quotes and net terms out of the box, without the transaction fees others charge. Its Open SaaS model lets you run headless via API when you want a custom storefront, at a cost well below the enterprise options. It gives ground to Shopify on app count and on extreme personalization. Choose it when your focus is B2B, you want managed SaaS and the headless door open without paying an enterprise price.
Shopify Plus
The king of time-to-market in D2C and B2C. Its app ecosystem, its best-in-class checkout and its launch speed are unrivaled when the catalog is not ultra-complex. It added B2B capabilities that cover D2C brands adding wholesale as a secondary channel well. Its limits show in very complex business logic and in the fees if you do not use Shopify Payments. Choose it when the priority is to launch fast, iterate on marketing and scale a direct-to-consumer brand.
How to choose: decision framework
The right platform falls out on its own when you order these six questions by weight for your business.
1. What is your dominant vertical: B2B, B2C or D2C?
B2B with complex negotiation logic pushes toward SAP Commerce Cloud, commercetools, VTEX or BigCommerce B2B Edition. High-volume B2C favors Salesforce Commerce Cloud or VTEX. Brand D2C prioritizes Shopify Plus. The vertical filters half the options up front.
2. How complex is your catalog and your operation?
Tens of thousands of SKUs, per-customer pricing, multi-warehouse and multi-country push toward enterprise. A bounded catalog with standard operations lives happily on SaaS. Do not pay for the complexity of commercetools or SAP if your operation will not use it.
3. How much technical team do you have or will you hire?
Pure composable (commercetools) requires sustained engineering capacity. SaaS (VTEX, BigCommerce, Shopify Plus) delegates much of that to the vendor. Choosing composable without a team is the most common recipe for a failed implementation.
4. What is your horizon and your appetite for lock-in?
If you are betting five years or more with features that evolve independently, composable or MACH architecture reduces the risk of getting trapped. If you want to solve the next two to three years at the lowest operating cost, a well-chosen SaaS is more rational.
5. Do you sell cross-border or only in Mexico?
Multi-country, multi-currency and local taxes raise the bar. VTEX and commercetools shine here; Shopify Plus handles it well with Markets. If you sell only in Mexico, do not buy international complexity you will not use.
6. What is your real TCO, not just the license?
Total cost includes license, implementation, integrations, maintenance and evolution. The license is usually the smaller part; implementation and operation are the bulk. Compare 3-year TCO, not the entry price. Our ranges by service are at /en/pricing.md.
3 common mistakes when choosing a platform
Choosing by brand, not by use case
The most-named platform is not the best for you by default. Shopify Plus is excellent for D2C and a bad idea for enterprise B2B with SAP integration. The use case rules over the marketing.
Ignoring implementation and operating cost
Comparing only the license price is the most expensive mistake. A "cheap" platform with a poorly scoped implementation costs more than a well-executed premium one. Evaluate 3-year TCO with integrations included.
Buying composable without the capacity to run it
Composable or MACH without a technical team or sustained partner ends in a project stalled halfway. If you do not have and will not hire that capacity, a managed SaaS is the honest decision.
Frequently asked questions
What is the best eCommerce platform for B2B in Mexico?
It depends on your size and the stack you already run. For enterprise B2B with massive catalogs and deep ERP integration, SAP Commerce Cloud and commercetools are the standards. For mid-market B2B with fast time-to-market, BigCommerce B2B Edition and VTEX are strong. VTEX stands out in LATAM when you need to unify B2B, B2C and marketplace on a single backend with local payments. Any answer that does not start with "it depends" is marketing, not technical advice.
commercetools or VTEX: which fits better in LATAM?
commercetools is pure composable: maximum flexibility, but it requires a technical team and does not include a frontend. VTEX is composable SaaS with native OMS and marketplace, local payments and leading LATAM adoption, with less architectural effort. If you need maximum composition freedom and have engineering muscle, commercetools. If you prioritize time-to-market in Mexico and LATAM with enterprise capabilities ready to use, VTEX.
Does Shopify Plus work for B2B?
Yes, with caveats. Shopify Plus added B2B capabilities (company catalogs, customer-specific pricing, net terms) that work well for D2C brands adding B2B as a secondary channel or for medium-complexity B2B. For B2B with complex negotiation logic, multi-level approvals, sophisticated per-customer catalogs or heavy ERP integration, platforms like commercetools, SAP Commerce Cloud, VTEX or BigCommerce B2B Edition remain more robust.
What is the difference between a SaaS platform and a composable (MACH) one?
A SaaS platform (Shopify Plus, BigCommerce, VTEX) delivers an integrated product managed by the vendor: fast to launch, less maintenance, less deep control. A composable or MACH platform (commercetools) is a set of API-first microservices you assemble to fit: maximum flexibility and scalability in exchange for greater architectural effort and a technical team. Several modern SaaS platforms offer headless modes that bring both worlds closer. See also our MACH Architecture page.
How much does each enterprise eCommerce platform cost?
Ranges vary by licensing model. Shopify Plus starts around US$2,300 per month. BigCommerce Enterprise is custom-quoted, typically in the order of US$1,000 to 15,000 per month based on GMV. VTEX and Salesforce Commerce Cloud usually run on a percentage-of-GMV model. commercetools licenses from the order of tens of thousands of dollars per year. SAP Commerce Cloud is high enterprise licensing. In every case implementation is additional and is usually the larger cost: between US$30,000 and 400,000 or more depending on complexity. See /en/pricing.md.
BigCommerce vs Shopify Plus: which one to choose?
Shopify Plus wins on launch speed, app ecosystem and checkout, ideal for D2C and B2C with a catalog that is not ultra-complex. BigCommerce wins on native B2B (B2B Edition), no transaction fees and headless flexibility (Open SaaS) at a lower cost than enterprise options. If your focus is D2C with intensive marketing, Shopify Plus. If your focus is mid-market B2B with a headless option, BigCommerce.
Is it worth migrating from a monolithic suite (SAP or Adobe Commerce) to composable?
It depends on your current pain and horizon. Migrating to composable or MACH makes sense when the monolithic suite slows time-to-market, every release is costly, vendor lock-in is high or you need to scale features independently. It does not make sense if your monolith performs and there is no clear business case. Migration is a 6 to 12 month project; it is best evaluated with a formal discovery before committing.
Do I need an internal technical team for a composable platform?
Yes, or a partner that provides it on a sustained basis. A composable platform like commercetools does not include a frontend or ready orchestration: someone must assemble services, maintain integrations and evolve the storefront. You can cover it with an internal team, a specialized lab or agency, or a hybrid model. If you do not have and will not hire that capability, a managed SaaS (VTEX, BigCommerce, Shopify Plus) is a better decision.
Which platform is best for cross-border selling from Mexico?
For cross-border, native support for multiple currencies, languages, taxes and local payment methods matters. VTEX is strong in LATAM and regional payments; Shopify Plus has Markets for multi-country with good time-to-market; commercetools offers the most multi-country control in exchange for more architecture. The decision depends on how many markets you will open, with what tax and logistics depth, and on your technical capacity.
Closing
Choosing an eCommerce platform is not choosing the most advanced or the most named one: it is choosing the one that fits your vertical, your operational complexity, your team and your horizon. The six platforms in this guide are serious and none is "the best" in the abstract. commercetools, Salesforce and SAP play in enterprise; VTEX, BigCommerce and Shopify Plus solve mid-market with SaaS. Adobe Commerce, when it appears, is almost always a migration conversation, not a comparison one.
