# #10093 [Bug][SubscriptionBilling]: "Prices Including VAT" handling is incomplete — contract billing invoice treats VAT‑exclusive Subscription Line amounts as VAT‑inclusive

> The Subscription Billing contract billing feature now correctly grosses up net prices to VAT-inclusive amounts when a customer or vendor uses prices including VAT, ensuring VAT calculations reconcile with the original order.

[Pull request](https://github.com/microsoft/BCApps/pull/10093) · merged into `main` (BC30) on 2026-08-28 by miljance (community contribution) · 2 files (+283 -6), 1 AL · fix · tier official · reviewed (checked by Opus)

## What changed

- Added a helper function to convert net prices to VAT-inclusive prices by applying the line's VAT factor
- Applied the gross-up logic at all price-assignment sites for both sales (Unit Price) and purchase (Direct Unit Cost) paths
- Zero-VAT and full-VAT lines are excluded from the conversion logic
- Comprehensive test coverage added for VAT-inclusive and VAT-exclusive scenarios for both customer and vendor billing
- Change is gated on the document header's Prices Including VAT flag and does not affect other documents
- Behaviour changes for users or extensions.
