Choose Mode 1 (per-line rounding) or Mode 2 (rounding on total) directly on the supplier order — just like on supplier invoices. The choice is persistent and reapplied on every recompute, without modifying the Dolibarr core.
On a supplier order, Dolibarr offers no VAT rounding mode choice (unlike invoices). When the VAT total differs by a few cents from the supplier's confirmation, this module fixes it in one click.
Two buttons on the order card: Mode 1 = sum of per-line rounded VAT; Mode 2 = VAT rounded on the total. Identical to the native behaviour of supplier invoices.
The mode is stored on the order and reapplied automatically on every totals recompute (adding, editing or removing a line). No risk of forgetting.
A simple extrafield + a hook: install in custom/, no Dolibarr core line touched. Cleanly removable, your data stays intact.
