FAQ

Shopify integration FAQs

How much does a Shopify ERP integration cost?

The cost depends on the systems involved, how much data moves and how often, and how much custom logic is needed. We give you a fixed estimate after a short discovery and data-mapping phase.

Should we use an off-the-shelf connector or a custom integration?

If a well-supported connector covers what you need, we'll recommend it, as it's usually quicker and cheaper. We build custom integrations when your data, rules or volumes don't fit what the connectors can do.

Who maintains the integration after launch?

You own the code and the documentation, so your own team or another developer can maintain it. Most clients keep us on a support plan for monitoring, fixes and Shopify API version updates.

Can you take over an integration another agency built?

Yes. We start with a review of the code, logging and data flows, then tell you what's sound, what's at risk and what we'd change before we take it on.

Do we need Shopify Plus for Functions and checkout extensions?

Some features need Shopify Plus, including checkout UI extensions on the information, shipping and payment steps. Many Functions, such as custom discounts, work on any plan with a custom app. We'll confirm what your plan supports during discovery.
