Topic: Manual VAT Adjustment on Supplier Invoice Lines
Audience: Accounts Payable, Finance Teams, and Advanced Users
? Overview
Turbo Inventory now supports manual editing of the VAT amount on individual supplier invoice lines. This enhancement is in response to supplier invoice discrepancies often caused by:
Rounding differences (unit-level vs. line total)
Supplier calculation methods (e.g. pack-based VAT rounding)
Third-party accounting software exports
This new feature gives you complete flexibility and control to match the invoice as supplied — even when the calculated VAT doesn't align exactly.
✅ Key Feature: Editable VAT Amount
? Note: This feature lets you edit the VAT amount, not the VAT rate.
Why This Matters:
In many real-world scenarios, suppliers calculate VAT at different levels (unit vs total), resulting in small discrepancies. Manually entering the correct VAT ensures your ledger stays aligned with the actual supplier invoice and avoids reconciliation errors.
? Step-by-Step: Editing VAT on a Supplier Invoice Line
Open Supplier Invoice Entry
Navigate to Purchasing > Supplier Invoices
Select or create a new supplier invoice
Select Supplier & Goods Receipt
Choose your supplier (e.g. Big Red Cloud Ltd.)
Select a relevant Goods Receipt Note
Enter Invoice Line Details
Input your quantity, unit cost, and total as normal
VAT will auto-calculate based on standard rates
Manually Edit the VAT Amount
Click into the VAT field on the line
Enter the exact VAT amount from your supplier invoice
? Once entered, this VAT amount is locked in — even if the line total or cost changes afterward
Review & Adjust Line Total
Update the line total if needed to reflect the new VAT-inclusive total
Any discounts can still be applied; VAT will not auto-update
System Validation
Turbo will validate your entries
If other lines exist, they will calculate VAT automatically unless manually overridden
Save the Invoice
Once you’re satisfied with all entries, save the invoice
Your manually entered VAT will persist as-is
?️ Additional Notes
Manually entered VAT does not recalculate even if quantity or cost changes.
You can reset the invoice if you need to revert to system-calculated VAT.
This control is line-specific — other lines on the same invoice will remain dynamic unless manually edited.
? Who Should Use This?
Accountants reviewing discrepancies between supplier invoice totals and system-calculated values
Finance team members needing to replicate supplier invoice totals exactly for audit or compliance reasons
? Benefits Recap
✔ Match supplier invoice exactly
✔ Avoid reconciliation mismatches
✔ Full line-level VAT control
✔ Seamless user experience within familiar invoice flow
