Track vendor prepayments without leaving the purchase order
Register percentage- or fixed-amount deposits directly on a confirmed purchase order, schedule them in stages, create the draft down-payment bill automatically, and net paid deposits off the final vendor bill — with a cross-PO dashboard showing exactly what is outstanding.
The problem
Standard Odoo purchase-to-bill only expects a vendor bill after goods or services are received, so there is no structured place to record a deposit paid up front. Finance teams end up tracking vendor prepayments in spreadsheets or burying them in generic vendor bills with manual notes, losing the audit trail between what was promised on the PO, what was paid upfront, and what is left on the final invoice.
The solution
Register a percentage- or fixed-amount prepayment directly on the purchase order, split it across staged milestones with due dates, and let the module create the draft down-payment bill, track it through paid, and apply it to the final vendor bill as a negative line — with one dashboard showing every prepayment across every open PO.
Everything a vendor deposit needs
Every capability below is implemented in the module.
Register From the PO Itself
Launch the Register Prepayment wizard from a header button on a confirmed purchase order — no detour to a separate billing screen.
Percentage or Fixed Amount
Calculate the deposit as a percentage of the order total, or enter the exact flat figure the vendor quoted.
Multi-Stage Schedules
Add sequenced milestones — a deposit at confirmation, a second installment before delivery — each with its own label and due date.
Automatic Draft Bill
Confirming a prepayment generates a draft down-payment vendor bill for the deposit amount automatically — nothing to type twice.
Full Lifecycle Tracking
Each deposit moves through Draft, Requested, Paid, and Applied on a statusbar, with a chatter log of every change for a clean audit trail.
One-Click Apply to Final Bill
Net a paid deposit against the final vendor bill as a negative line with a single button — no manual subtraction, no risk of double-billing.
Cross-PO Dashboard
See every prepayment across every open purchase order in one list, colour-coded by status, instead of checking each PO individually.
Prepayment Analysis
Pivot and graph views break down outstanding, paid, and applied prepayment value by vendor and by status.
Default Percentage & Due-Date Reminders
Set a company-wide default deposit percentage in Settings, and let a daily cron flag overdue prepayments as a to-do activity automatically.
How it works
Register the deposit
From a confirmed PO, open Register Prepayment and set the type, amount, milestone and due date.
Draft bill created
Confirming the prepayment generates a draft down-payment vendor bill for the deposit amount.
Mark it paid
Once the vendor has been paid through your usual AP process, register the payment to move the deposit to Paid.
Apply to the final bill
When the final vendor bill arrives, apply the paid deposit to net it off as a negative line automatically.
Frequently asked
No sales fog. If your question isn't here, email us and we'll answer it the same way.
Yes. A purchase order can carry any number of prepayment records, each with its own milestone label, due date, and percentage or fixed amount — for example a deposit at confirmation and a second installment before delivery.
