Shopify integrations with your ERP, POS or any API
When Shopify needs to talk to the systems your business actually runs on (ERP, POS, PIM, logistics), an off-the-shelf connector rarely fits. I design and build custom integrations: contract pricing from Microsoft Business Central pushed into Shopify, live repair prices from Lightspeed, subscription data from Recharge, events into Klaviyo. Two-way, scheduled or real-time, with the reconciliation tooling to prove the data is right.
Sound familiar?
- ✕Your ERP is the source of truth but Shopify never matches it
- ✕B2B customers have contract prices that Shopify can't show
- ✕The 'official' connector app syncs half of what you need
- ✕Orders are exported by hand because no integration exists
What you get
- ✓Custom two-way syncs between Shopify and ERP/POS/PIM systems
- ✓B2B pricing: per-customer and per-group contract prices in Shopify, even without Shopify Plus (I've built this on a standard plan, where it officially isn't possible)
- ✓OAuth-secured API middleware you own, with no vendor lock-in
- ✓Scheduled and webhook-driven syncs with retries and alerting
- ✓Reconciliation and audit scripts that catch mismatches early
- ✓Documentation and handover so any developer can maintain it
Live: fire a test order through an integration
This is what my integration work does all day: Shopify events fanning out to ERP, email and fulfillment. Press the button and watch one order make the trip.
Press the button. Six systems are waiting.

A B2B store where every customer has negotiated contract prices living in Microsoft Dynamics 365 Business Central. I built the integration that keeps thousands of customer-specific prices correct in Shopify, automatically. And it runs entirely without Shopify Plus, on a plan that officially doesn't support per-customer pricing at all.

Frequently asked questions
Which systems have you connected to Shopify?+
Microsoft Dynamics 365 Business Central, Lightspeed POS, Recharge, Klaviyo, Mollie, Stripe, Print API, review platforms and several custom/legacy systems, including keeping a legacy production-planning app running unchanged through a compatibility middleware during a platform migration.
What happens when a sync fails at night?+
Good integrations assume failure: retries with backoff, idempotent operations so nothing duplicates, and alerting so we know before your customers do. I build all three in by default.
Can't we just use Zapier or Make?+
For simple, low-volume flows: absolutely, and I'll tell you so. For pricing syncs, bulk data or anything business-critical, per-task pricing and missing error handling make no-code tools fragile and expensive. That's when custom wins.
