Choosing an
enterprise platform
in 2026.

Choosing an enterprise ecommerce platform is normally a decision a company makes once a decade and tries very hard not to think about in between. In 2026, that calm is gone. A rare combination of forces, a forced mass migration off a legacy platform, a cooling of the composable hype that drove the last cycle, and a genuine reshuffling of which platforms are winning and losing, has made this the most consequential year for enterprise platform decisions in a long time. If you are on a buying committee this year, you are making the call under unusual pressure.

I advise enterprise commerce teams on exactly these decisions, and I have watched the same mistakes repeat: choosing on a feature checklist instead of fit, underestimating total cost by a wide margin, and treating a platform decision as a technology choice when it is really a strategy and operating-model choice. The stakes are high enough that getting it wrong sets a brand back years, which I argued in the platform bottleneck piece.

This is the honest shortlist and decision framework for 2026. Why this year is different, the platforms actually worth considering and who each fits, what the composable promise really delivered, the total cost reality, and how to make the call without getting captured by a vendor's pitch.

The terms a buying
committee throws
around.

Enterprise commerce is thick with architecture jargon, much of it used loosely to sell a particular approach. Here is the plain-language version.

Keep the GMV-to-architecture link in mind. The single most common enterprise mistake is buying a composable architecture the business is too small to justify, which we will get to.

The largest forced
migration in
commerce history.

The reason 2026 is unusual comes down to a single date. SAP Commerce on-premise, the platform most people still call Hybris, reaches mainstream end-of-maintenance on July 31, 2026. More than 3,200 enterprise organizations have to migrate off it by then, which is the single largest forced enterprise replatforming event the industry has ever seen (Elogic). Early migration patterns show roughly 40% moving to SAP's own Commerce Cloud, about 18% to commercetools, and around 15% to Adobe Commerce.

This matters even if you are not on Hybris, for two reasons. First, it floods the market with enterprise migrations all at once, which strains implementation partners and pulls vendor attention toward the biggest deals, so timing and partner availability are tighter than usual this year. Second, it is forcing a wave of architecture decisions in compressed time, which is exactly when buying committees make rushed, checklist-driven choices they regret. If you are migrating under this deadline, the pressure to decide fast is precisely the pressure to resist.

The platforms worth
your shortlist, and
who they fit.

There are really five platforms that belong on most enterprise shortlists in 2026, and the right answer depends far more on your fit than on any feature ranking. Here is the honest read on each.

Notice that none of these is the answer for everyone. The buying committees that get this wrong start from "what is the best platform" and end up captured by whichever vendor ran the best demo. The committees that get it right start from "what is our profile," GMV band, B2B versus B2C mix, catalog complexity, existing systems, and team capability, and let that narrow the field before a single demo. This is the same build-versus-buy-versus-partner discipline I laid out in the build, buy, partner piece.

Composable was
oversold to brands
too small for it.

The last platform cycle was dominated by the composable, or MACH, pitch: break apart the monolith, assemble best-of-breed pieces, gain total flexibility. For the right enterprise, it is genuinely powerful. The problem is how far down-market it got sold. Composable architectures are now used by an estimated 34% of companies above $1 billion in GMV, up from 26% in 2024, but adoption falls off sharply below $200 million in GMV (Elogic). That cliff is not an accident. Below a certain scale, the flexibility of composable is not worth its complexity and cost.

I have watched mid-market brands buy composable architectures, spend two years and a fortune assembling and integrating the pieces, and end up with something slower to change than the monolith they left, because now every change touches five vendors instead of one.

Composable is a real answer for enterprises with the scale, the engineering team, and the genuine need for architectural control. It is a budget trap for the brand that bought the pitch without the prerequisites. The honest question is not "monolith or composable," it is "do we actually have the scale and the team to make composable pay off," and for most brands under a few hundred million in GMV the answer is no.

The license is the
small number.

Total cost of ownership is where enterprise platform decisions go wrong financially, because the license fee is a fraction of the real number once you add hosting, implementation, integration, customization, and the team to run it.

The platforms differ here by a lot. By Shopify's own analysis, its total cost of ownership runs about 33% lower than competitors on average and up to 36% lower at the high end, with Salesforce's overall TCO around 54% higher than Shopify's (Shopify Enterprise). Treat vendor-published comparisons like that as directional rather than gospel, since the vendor publishing them has an obvious interest, but the broad pattern, that operationally lighter platforms cost less to run over time, holds up across independent analyses too.

Implementation speed is the other cost that hides on the timeline rather than the invoice. The same analyses put Shopify storefront launches roughly 28% faster than Salesforce, with some partners reporting 50% to 75% shorter implementation timelines versus Salesforce Commerce Cloud. For an enterprise, months of delay is real money in lost sales and carrying cost, so speed to launch belongs in the TCO conversation, not separate from it. The platforms that are heavier to customize, Adobe Commerce especially, buy you control at the cost of a longer, more expensive build.

The market is
moving, and it
tells you something.

Platform momentum is a signal worth reading, because a platform losing customers is a platform whose ecosystem, talent pool, and roadmap investment are at risk. The movement in 2026 is real. Adobe Commerce live stores fell about 15% year-over-year in early 2026, with over 1,700 stores leaving in a recent 90-day window, a meaningful share of them moving to Shopify and Salesforce (Elogic). Adobe still powers an enormous base, an estimated $173 billion in annual GMV and a fifth of the top 1,000 US retailers, so this is erosion, not collapse, but the direction is clear.

On the other side, commercetools crossed a $100 billion annualized GMV run-rate in early 2026, up from $75 billion months earlier, more than 60% year-over-year growth, with customers like Audi, Danone, Sephora, and Volkswagen Group. And Shopify Plus has moved decisively up-market, with Shopify B2B GMV growing 96% across 2025, which for the first time makes Plus a credible enterprise B2B platform rather than just a DTC one, a shift I traced in what Shopify taught the enterprise. The read for a buyer: weight momentum alongside fit, because you are betting on where a platform will be in five years, not just where it is today.

The questions that
narrow the field
before the demos.

Here is the sequence I run with enterprise teams, designed to reach a decision based on fit rather than on whoever sells hardest. Answer these in order, and the field narrows itself.

What is our GMV band? This alone eliminates most options. Below a few hundred million, composable is usually the wrong call and a strong monolith or Shopify Plus is the efficient answer. Above a billion with genuine complexity, composable earns its place.

B2B, B2C, or both? A unified B2B and DTC requirement now favors Shopify Plus in a way it did not two years ago, while the most complex B2B catalogs still pull toward Adobe Commerce.

What are we already locked into? A deep existing Salesforce or SAP footprint changes the math, because the integration value can justify a premium that would otherwise be indefensible.

What is our team actually capable of running? Composable demands real engineering capacity. If you do not have it and cannot hire it, a flexible architecture you cannot operate is worse than a simpler one you can.

How fast do we need to move? Under the Hybris deadline or any time pressure, speed to launch is not a nice-to-have, and the operationally lighter platforms win on it decisively.

Choosing is half.
Migrating is the
hard half.

Picking the platform is the decision everyone focuses on. The migration is where the value is actually won or lost, and where most of the pain lives. An enterprise replatform is a multi-quarter program with real risk: data migration, integration rebuilds, a period where the new system is not yet proven, and the organizational change of moving teams onto new tools. Done well, it takes longer and costs more than the optimistic plan, and the brands that survive it are the ones that phased it, ran old and new in parallel where they could, and refused to cut over everything at once under deadline pressure.

The Hybris deadline makes this harder, because a forced timeline tempts teams to rush the riskiest part. Resist it. If the deadline is genuinely immovable and the migration cannot be done safely in time, a deliberate interim step is better than a rushed full cutover that fails in production. The board needs to understand the replatform as the multi-year, high-stakes program it is, not a procurement event, which is part of the conversation I laid out in the board conversation on commerce.

The 2026 enterprise platform decision is loaded by a forced migration, a cooling of the composable hype, and a real shift in which platforms are winning. Cut through it the same way every time: start from your profile, not the vendor's pitch. Know your GMV band, your B2B and B2C mix, your existing lock-ins, your team's real capability, and your timeline, and let those narrow the field before a demo ever runs.

Weight momentum alongside fit, respect the total cost of ownership over the license quote, and treat the migration as the high-stakes program it is. Choose for the business you actually are, not the one the vendor's slide says you should be, and you will not spend the next decade living with the wrong platform.

Making the platform call without getting captured by a vendor is exactly the kind of decision I work through with enterprise teams. It is part of the enterprise commerce innovation practice, and the form takes two minutes: start the conversation.
