Integrations Overview
Synplex connects to three categories of external systems. Shopify is the core connection that powers everything. Supplier catalogs and custom integrations are optional additions for specific needs.
What Synplex integrates with
| Integration | What it does | Who needs it |
|---|---|---|
| Shopify | Syncs products, inventory levels, locations, and orders in real time | Everyone — required |
| Supplier catalogs | Imports supplier SKUs, unit costs, MOQs, and lead times so costs pre-fill in POs | Anyone who creates purchase orders |
| Custom / ERP | Connects Synplex to accounting systems, 3PLs, warehouses, or internal tools via API | Teams with existing business systems to integrate |
Which integration do I need?
"I want unit costs to pre-fill when I create a PO" → Supplier Catalog Integrations — upload a CSV from your supplier or connect a recurring API sync
"I want POs to sync to QuickBooks, NetSuite, or Xero" → ERP & Custom API Integrations — reference guide for building a custom integration
"I want to sync inventory from a 3PL or warehouse system" → ERP & Custom API Integrations — covers 3PL patterns and API integration approach
"I want to understand exactly what Shopify data Synplex reads and why" → Shopify Sync – Technical Details — full breakdown of permissions, webhooks, and data models
Getting started
Most users only need the supplier catalog integration. If you have already connected Shopify during setup, the next step is adding your supplier pricing so costs are available when you create purchase orders.
Custom integrations are for teams with existing ERP or warehouse systems. They require development work and are not needed for standard Synplex usage.
