Integration · POS & Counter
Unified retail and online commerce
Shopify POS is designed to share inventory and orders with a Shopify-powered online store natively. When your storefront runs on Parts Square, this integration keeps that same unified inventory model working — one stock count across your counter and your site.
Why connect Shopify POS
Unified Commerce POS — connected so your counter and your storefront always agree.
Because Shopify POS and your online catalog already share a stock model, the integration keeps that single source of truth intact.
Customers created at the counter in Shopify POS are recognized on your storefront, and vice versa.
Keep using Shopify POS at the counter exactly as today — Parts Square connects to it, rather than replacing it.
What syncs
Here's exactly what stays aligned between Shopify POS and your Parts Square storefront.
Stock changes from counter sales or receiving in Shopify POS reflect on your storefront automatically.
Orders placed online and at the counter share the same order history and numbering.
Customer accounts created at checkout or the counter are unified across both channels.
Product variants (size, brand, part number) set up in Shopify carry through to your storefront listings.
Orders are fulfilled from the correct Shopify POS location based on stock and proximity.
Setup process
No rip-and-replace. Shopify POS keeps running the counter — we connect around it.
Share read-only credentials or API access so Parts Square can safely connect to Shopify POS — no changes to how your counter operates.
We match your existing items, categories, and pricing tiers to your storefront so nothing has to be re-entered.
We run a controlled sync and review a sample of orders and stock changes with you before anything goes live.
The connection runs continuously in the background — your counter team keeps working exactly as before.
