Troubleshooting: Inventory Sync Groups
Use this page when your group inventory doesn’t look correct or doesn’t update as expected.
✅ Before you start (quick checklist)
Refresh the page and wait 1–2 minutes (some updates are not instant).
Confirm the products/variants are in the same Inventory Sync Group.
If you use Smart Scan, confirm the SKU format is correct and consistent.
1) Inventory is not updating
What you see
Inventory changes in Shopify, but the other grouped products don’t update.
Most common causes
Inventory tracking is OFF for one or more variants.
Inventory was updated in a location not used (or not the intended location).
The products are not actually grouped (wrong variants selected).
The change hasn’t been processed yet.
How to solve
Open Shopify Products > open the product > check Inventory section
Make sure Track quantity is enabled for the variants in the group
Confirm you updated inventory in the correct location
Go to Tipo app > Inventory Sync Groups and confirm the variants are included
Make a small test change (e.g., adjust by +1) and check again
2) Wrong quantities after grouping
What you see
After creating a group, inventory numbers look unexpectedly high/low.
Why it happens
When a group is created, the app needs a single “shared quantity” for the group.
If variants had different inventory before grouping, the result may look “wrong” depending on how your store was set up.
How to solve
Decide what the correct shared inventory should be (example: “We have 100 total”)
Update the inventory for one variant to the correct value
Let the group sync apply the same number to the other variants
Re-check that all variants show the same inventory
3) Products not detected by Smart Scan (Auto-group by SKU)
What you see
Smart Scan doesn’t create groups or misses products you expected.
Most common causes
SKUs are empty for some variants
SKUs don’t match exactly (spaces, lowercase/uppercase, extra characters)
SKUs are unique (no duplicates = nothing to group)
Only some variants share the SKU
How to solve
Export your product CSV (or open products) and check SKU values
Make SKU formatting consistent (example:
TSHIRT-RED-M)Re-run Smart Scan
If your SKUs are not designed to match, use Manual group creation instead
4) Group conflicts (a product/variant appears in multiple groups)
What you see
A variant is already grouped and you can’t add it again (or syncing behaves inconsistently).
Why it happens
A single variant should belong to only one Inventory Sync Group to avoid conflicting inventory updates.
How to solve
Find the product/variant inside Inventory Sync Groups
Identify which groups currently contain it
Remove it from the old group (or delete the old group)
Add it to the correct group
Save and re-check inventory
