Vendor advances are raised on the same document shape as a manual payment, with charge lines, simulation and the advances the supplier already holds shown alongside.
Simulate Before Posting, and See What the Vendor Already Holds
The advance payment page gained a Simulate step that mirrors the posting line for line, and a derived totals bar — Advance Recorded, Charges, Withheld, Vendor Receives, Bank Pays.
Where a manual payment lists the open items it will clear, an advance lists the advances the supplier already holds on account, so nobody wires a second one without seeing the first. If that panel cannot be read, it says so rather than showing a clean account.
Charges and Withholdings on an Advance
An advance payment now carries the same charge lines a manual payment carries. Charges and withholdings change how much cash leaves the bank, never what is recorded on account against the vendor — so the advance shown as open is always the advance that was agreed.
Withholding more than the advance is worth is refused (that is a refund, not a payment), as is a charge account that cannot be resolved or belongs to another company. An advance raised with no charge lines posts exactly as it always did.
Advance and Down Payment Screen Refresh
The Advance Payment and Vendor Down Payment screens were reworked around the header / on-account / charges / totals layout, so the two documents read the same way.
