Why Growing B2B and DTC Brands Are Rethinking Their Ecommerce Infrastructure in 2026

A growing number of B2B and DTC brands are running the same calculation this year: what their ecommerce stack actually costs once every app subscription, integration fix, and developer hour gets added to the platform fee. The answer is pushing a broader look at ecommerce infrastructure itself, not just which platform sits underneath it.

The real cost of a bolted-together stack

A platform's sticker price rarely reflects what it costs to run. Additional apps with specific jobs - collecting and posting product reviews, optimizing shipping workflows, integrating social media feeds - each have their own cost. Together, they add another source of ongoing maintenance: more code slowing down your website, broken integrations, failed updates. When something fails to run properly, it can be unclear whether the fault lies with the platform, one app, or the connection between them.

That's something brands increasingly account for when they evaluate total cost of ownership. Not just the monthly fee, but the engineering and support hours spent keeping a patchwork of third-party solutions working together over a three-to-five-year horizon.

Native vs. third-party: what counts for infrastructure

The distinction driving most of this rethinking is native versus third-party. Bolted on infrastructure pairs a core platform with specialized apps provided by third parties. While that approach can increase flexibility and be necessary for edge cases, every added app is another point of failure and another vendor relationship to manage. Native infrastructure builds core commerce functions directly into the platform, trading some of that flexibility for fewer moving parts and one vendor accountable for the whole system.

Neither approach is categorically right. A brand with highly specific, low-volume workflows may genuinely need the customization a bolt-on stack allows. A brand running standard commerce operations at real volume often finds the app layer becomes overhead rather than an advantage.

Where scalability breaks first

For brands running B2B and DTC side by side, the cracks tend to show in the same places: checkout logic that has to handle both bulk, negotiated-price buyers and individual retail customers; catalog and pricing rules that get more complex with every new customer segment; support response times that don't scale with order volume; and inventory or customer data that drifts out of sync across disconnected systems. None of these are dramatic failures on their own. But they can cause compounding friction until someone finally asks why a routine task takes six tools instead of one.

What rethinking infrastructure looks like in practice

Instead of comparing monthly fees, more businesses are calculating total cost of ownership over several years. Instead of asking "can we add this feature," they're counting how many separate vendors it takes to run core commerce operations. And they're specifically checking whether functions like tax compliance, subscriptions, and wholesale selling are native to the platform or dependent on a third-party app staying maintained and compatible.

Merchant Tech is one example of a platform built around that model at the small-to-mid-market end of the spectrum: order fulfillment, shipping, multi-channel selling, and customer-facing features like product reviews and website customization are native rather than assembled through apps, for a flat $79/month with transaction fees from 2.9% + 30¢ (verified against merchant.tech's site as of 8/10/26). It's representative of the native-infrastructure approach more B2B and DTC brands are weighing against the third party stacks they've outgrown.

The infrastructure question isn't going away as B2B and DTC operations keep converging under the same roof. The more useful exercise is asking what the current stack actually costs to maintain, then deciding how much of that cost is worth paying for flexibility versus trading for simplicity. Platforms and pricing change, so it's worth confirming current terms directly with any vendor before deciding.
