Problem Description

A specific product at the POS terminal is not displaying or calculating tax, even though other products are taxed correctly. The issue is isolated to one product or a subset of products and persists after normal POS restart.

Symptoms

• Tax is missing from a specific product's line item on the POS transaction screen
• The transaction completes without tax for the affected product
• Other products in the same transaction show tax correctly
• The issue may appear after a product configuration change or data sync

Environment / Prerequisites

• Applies to iVend Retail POS
• Issue is product-specific — not a global tax configuration failure
• May occur after product data is edited in the back office or imported

Root Cause

TO BE VERIFIED — Based on: product-specific tax absence at POS is typically caused by the product's tax code being missing, incorrectly mapped, or not replicated to the store after a back-office change.

Resolution Steps

1. In iVend Back Office, navigate to the affected product and verify that a tax code is assigned.
2. Confirm the tax code is active and mapped to the correct tax rate.
3. Check whether the product belongs to a product group with a tax override and verify the group's tax setting.
4. If the tax code is correct in back office, force a data refresh or replication to push the latest product data to the store.
5. Restart the POS and test the product again.
6. If the issue persists, check the POS tax calculation logs for the specific product ID.

Verification

To verify: The affected product now shows the correct tax amount on the POS transaction screen. Process a test transaction and confirm the tax line appears in the receipt.

Workaround

Temporarily assign an alternative tax code to the product while the root cause is investigated.

Prevention / Notes

After any bulk product import or back-office data change, run a replication cycle and spot-check tax on recently modified products before the store opens.
