The typical story
You decide your Shopify store needs to talk to your ERP. A developer (or agency) gives you a 6–8 week estimate. Three months later, you're still debugging edge cases, and the project is over budget.
Why does this keep happening?
The five real reasons ERP integrations take so long
1. Data model mismatches
Shopify's data model and most ERPs were designed independently. An "order" in Shopify has a different structure than a "sales order" in Dynamics NAV. Mapping them correctly takes time — and discovering edge cases takes longer.
2. No standard ERP API
Unlike Shopify, which has a well-documented public API, many ERPs (especially older ones) have inconsistent or poorly documented APIs. Building on top of them is slow work.
3. Scope creep
"We also need to sync customers." "And refunds." "Can we add vendor pricing?" Every addition is reasonable in isolation. Together, they turn a 4-week project into a 4-month project.
4. Testing complexity
Integration testing requires both systems to be in sync. Setting up test environments, generating realistic test data, and validating edge cases is genuinely hard and time-consuming.
5. Maintenance after go-live
Shopify updates its API regularly. So does your ERP vendor. Custom integrations break. Someone has to fix them.
The faster path
Purpose-built connectors solve most of these problems by handling the data mapping, API complexity, and maintenance for you. Instead of starting from scratch, you configure a pre-built connector to your specific requirements.
