A massive inventory wipe just occurred. You've successfully identified the root cause—a rogue CSV import or a failing sync app. Now, you just need to put the stock back to normal.
This is the moment where most merchants make a critical mistake.
Blindly restoring the stock to its pre-incident state without accounting for what happened in the interim can lead to overselling or underselling.
Safe Restoration Principles
- 1Do not blindly overwrite the current stock with the pre-incident number.
- 2Calculate the delta: Subtract orders that occurred during the downtime.
- 3Ensure the offending app is paused so it doesn't overwrite your fix.
- 4Audit downstream fulfillment networks before pushing the update.
Root Causes
Why blind restoration is dangerous
If your inventory dropped from 120 to 0, and you immediately type '120' back into the dashboard, you are ignoring the possibility that orders or transfers occurred during that window.
Orders after the incident
If Shopify allowed backorders or if stock was synced incorrectly across multiple locations, you must subtract the units sold during the incident window before restoring.
Downstream inventory changes
If your Shopify store is connected to a 3PL or Amazon MCF, restoring stock blindly might trigger an outbound sync that overrides the warehouse's true physical count.
Step-by-Step Fix Guide
Halt the Offending Source
Before changing any numbers, disable the sync app, API connection, or staff permissions that caused the incident to prevent a recurrence.
Calculate the Safe Revert Number
Take the pre-incident stock, subtract any sales or transfers that occurred since the incident began, and use the resulting number as your recovery target.
Restore Inventory
Input the calculated safe recovery number into Shopify, ensuring it applies to the correct location.
Verify Downstream Syncs
Manually trigger or verify that your WMS, ERP, and marketing feeds reflect the correctly restored number.
Stop guessing your recovery numbers
Inventory Guard features a dedicated Safe Revert flow, allowing you to restore inventory while automatically accounting for downstream changes.
