Problem
A specialty retailer ran a storefront, a marketplace, and their accounting as three disconnected systems. Inventory drifted between them, sales tax landed in the wrong account, and every listing’s custom fields (size, offset, finish) were rebuilt by hand.
Approach
Wire the three systems together around clear rules instead of a big rebuild: inventory deducts on a booked sale, sales tax maps to the right ledger account, and listing custom-fields are templated and bulk-loaded. Existing marketplace listings stay manual on purpose, to preserve years of sales history.
Stack
BigCommerce (storefront), eBay (marketplace), and QuickBooks (accounting) tied together via their connectors and webhooks, with a CSV bulk-load path for listing custom fields.
What shipped
Inventory-to-accounting sync is live; tax mapping and a paid multi-channel marketplace connector are being finalized. Fixed a webhook edge case that created phantom accounting entries on failed payments.
What’s next
Finish the marketplace automation for new listings and hand the business-rule decisions back to the retailer.
