• Product identifiers (SKU, barcode/GTIN where available) are used to map Bigcommerce products and variants to Shopify POS/Shopify product records, with attribute and option values normalized between platforms.
• Inventory quantities are synchronized per location, with configurable ownership of “source of truth” and conflict handling when both systems report changes in the same window.
• Order data created in Shopify POS is transferred to Bigcommerce as sales records (including line items, taxes, discounts, and payment status where supported), with customer matching based on email or a stable external ID.
• Refunds and returns are handled through linked order references, and the integration reconciles financial adjustments back to the originating order record when available via APIs.
• Delta sync logic sends only changed products, prices, and stock updates, while full syncs are used for initial alignment and periodic validation.
• API calls and webhook events are validated, rate-limit aware, and logged with retry queues so failed transfers can be reprocessed and audited.

Why choose scandiweb to handle BigCommerce integration for you?
How do you connect BigCommerce with Shopify POS to sync inventory in real time?
Most setups use a middleware or custom API layer to map SKUs, locations, and adjustments, then push stock changes both ways. We QA edge cases like partial fulfillments, returns, and manual POS adjustments before Go-live.
Can BigCommerce and Shopify POS share one product catalog with variants and SKUs?
Yes, but it depends on strict SKU governance and a clear “system of record” for product attributes and barcodes. We align variant logic and option sets so POS scanning matches what BigCommerce sells online.
Does a BigCommerce – Shopify POS integration sync in-store returns, exchanges, and refunds to online orders?
It can, as long as order IDs, tender types, and return reasons are standardized across both systems. We typically design the flow so staff can process returns in POS without breaking BigCommerce reconciliation.
What customer data can be synced between Shopify POS and BigCommerce for omnichannel reporting?
Common fields include customer profiles, marketing consent flags, and purchase history references, with PII handled per GDPR and CCPA rules. For analytics, we also pass channel and store identifiers for clean attribution.
Will Shopify POS work with BigCommerce across multiple stores, locations, and currencies?
Yes, with location-level inventory mapping, tax rules per region, and currency handling defined upfront. This is where integrations fail most often, so we validate it against real store workflows, not just API docs.
