Two systems atcheckout: why wemerged them into one

In short

A brand was running a WooCommerce store for its pages and a Shopify checkout for purchases. It worked, but customers, orders and data were scattered. Every new feature had to be planned across two systems. We merged everything onto Shopify. Since then, new features get added on a stable foundation instead of a stopgap.

The case

Hybrid setups like this are rarely planned. At some point the checkout needed to get better, so Shopify was added. The old store stayed because, well, it worked. Over the years, a short-term workaround became the actual architecture. The result: two customer databases, orders in two places, plugins and apps that don't know about each other.

The solution

We didn't just rebuild the old look in Shopify. We rethought store, checkout and customer journey together and brought them onto one system:

1. Everything on Shopify. Pages, products, checkout, customers and orders in one system.
2. Customers and orders merged. One customer history instead of two halves.
3. Foundation first, extras second. Once the foundation was in place, we added on the same base: email automations, social commerce channels, store locator, reviews, chat, loyalty program, bundles and subscriptions.

In the old setup, each of these features would have been its own little integration project. On one system, they were setup tasks.

Your takeaways

• One system fewer can be worth more than ten new features. Every interface is a place where something can break.
• Check where your customer data lives. If you have to open two systems to see a complete customer history, you have an architecture problem.
• Workarounds age badly. What was meant as a transition often becomes permanent. Plan the end of a stopgap right from the start.
• A migration is your chance to rethink. Copying the old layout one to one wastes it.
