Shopify inventory sync without the spreadsheet

A regional ecommerce retailer stopped copying inventory counts by hand between Shopify and a shared spreadsheet — here's what changed.

Problem

The operations team updated inventory in Shopify and a shared Google Sheet every day. Wholesale orders, returns, and warehouse adjustments meant the two sources disagreed by afternoon. Staff spent an hour copying numbers and still shipped against stale counts.

Business impact

Oversells on popular SKUs twice a month
Customer service time spent apologizing for cancelled orders
Warehouse team distrusted both systems and kept their own notes
Owner could not see accurate stock without calling someone

What was broken

No single source of truth for inventory
Manual copy-paste between Shopify and the spreadsheet
Wholesale channel updates that bypassed the sheet entirely
No alerting when counts diverged

What changed

Shopify became the system of record for sellable inventory
Automated sync pushed counts to the spreadsheet for teams that still relied on it
Wholesale order flow updated inventory through the same pipeline
Daily reconciliation report flagged mismatches before they affected customers

Result

Manual inventory copy-paste dropped to zero for day-to-day operations. Oversell incidents stopped within the first month. The owner could check stock from one dashboard without calling the warehouse.

What this prevented

A rushed replatforming project the owner had been quoted. The fix sprint connected and stabilized existing tools instead of replacing everything.

This was a System Integration fix sprint. Similar situations often start with a Business Systems Audit.
