# Connecting Your Building-Materials ERP (Epicor & Others) to Shopify

> Syncing a building-materials ERP like Epicor to Shopify means moving large variant-heavy catalogs, layered contractor pricing, and yard-level inventory without letting the storefront drift from the ERP. This guide covers what syncs, what stays ERP-side, and the integration patterns that survive real order volume.

## Frequently asked questions

### Can Shopify handle a building materials catalog with hundreds of thousands of SKUs?

Yes, with deliberate architecture: variant modeling decided at initial load, metafields for technical attributes, and a delta-based sync that moves only what changed daily. The proven ceiling is high, Uncap's largest materials implementation syncs more than one million SKUs from Epicor.

### Should contractor pricing be calculated in Shopify or in the ERP?

Stable layers, trade tiers and contract rates, are mirrored into Shopify price lists so buyers see true pricing at browse time. Conditional pricing, job-specific or judgment-dependent, stays ERP-side and routes through a quote, so the storefront never approximates a calculation the ERP owns.

### How fast should pricing updates reach the storefront when commodity costs move?

Within minutes, via event-triggered sync, rather than at the next scheduled batch. A materials portal that lags its own repricing publishes numbers the business will not honor, which is the fastest way to teach contractors to call and confirm every price.

### Does this replace the generic Epicor-to-Shopify integration approach?

It builds on it. The platform pairing, connection method, data flows, setup, is the same foundation covered in Uncap's Epicor integration guide. The materials-specific layer is the item master modeling, UOM handling, layered pricing decisions, and branch inventory rules described here.
