E-commerce Platforms: Shopify, WooCommerce, or Custom-Built?
We've built exactly two fully custom e-commerce platforms from scratch in the last few years. Not because we couldn't build more — because almost nobody who asks us for one actually needs it. Shopify and WooCommerce have absorbed a decade of other people's edge cases, and most stores selling physical products fit inside that absorbed knowledge just fine.
What Shopify and WooCommerce already solve well
- Checkout, tax calculation, and payment gateway compliance — genuinely hard problems that thousands of engineers have already solved for you.
- Inventory sync across channels, abandoned cart recovery, discount codes, shipping rate calculation.
- A massive app ecosystem for anything reasonably common — subscriptions, loyalty points, reviews, local delivery scheduling.
- Security and PCI compliance handled by the platform, not something your small team has to own.
If your business is "sell products online, ship them, handle returns," this is the same conversation we cover in custom software vs SaaS — the honest advice is almost always to configure, not build.
Where the platforms start to strain
- Complex product configuration — bundles, made-to-order combinations, or pricing that depends on multiple interacting variables the platform's product model wasn't built for.
- B2B selling with negotiated pricing per account, credit terms, or approval workflows that don't map to a consumer checkout flow.
- Inventory that lives across a physical store, a warehouse, and a marketplace simultaneously, needing one source of truth none of the platforms natively provide.
- Transaction volume high enough that app-store pricing per feature starts costing more than a dedicated engineering team would.
The middle path: platform plus custom app
Most of our e-commerce work isn't "build a store" — it's building the specific custom app or backend service that plugs into Shopify or WooCommerce for the one thing the platform can't do out of the box, while leaving checkout, payments, and catalog management to the platform itself.
Before quoting a custom store, we ask what percentage of your product catalog actually needs the custom behavior. If it's 10%, you probably need a custom app bolted onto Shopify, not a custom platform replacing it.
When custom is genuinely the right call
It's a small list: marketplaces connecting multiple sellers, highly regulated products with compliance logic no platform anticipates, or transaction volumes in the millions where platform fees alone justify owning the stack. Outside of that, we'd rather spend your budget on the parts of the store that actually differentiate you — the product photography, the copy, the post-purchase experience — than rebuild a checkout flow that already works.
