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.
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.
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.
See it in action
From the cross-PO dashboard to the register wizard, every screen shown is running the real module.
The Prepayments dashboard lists every deposit across every purchase order, grouped by status with amounts and due dates at a glance.
Each deposit record shows its Draft to Applied statusbar, percentage or fixed amount, order total, milestone and due date.
The purchase order gets its own Prepayments tab with a status badge, aggregate requested / prepaid / applied amounts, and the inline list of staged deposits.
The Register Prepayment wizard, launched straight from the PO, lets the buyer pick percentage or fixed amount, due date, milestone label, and whether to create the draft bill immediately.
The Vendor Prepayments block in General Settings sets the default deposit percentage suggested when a new prepayment is registered.
Frequently asked
Can I split a single deposit into multiple stages?
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.
Does marking a prepayment as paid post or reconcile a payment in Accounting?
No, by design. Register Payment only updates the module's own tracking status so you can see what has been paid at a glance. The actual payment and bank reconciliation stay in your standard Accounting workflow, avoiding any duplicate payment matching.
What happens if I try to apply a prepayment before the final bill exists?
The module blocks it with a clear message asking you to create the final vendor bill on the purchase order first. Once a draft final bill exists, Apply to Final Bill adds the deposit as a negative line and drops the amount due by exactly the prepaid amount.
Which apps and Odoo versions does this require?
It builds on the standard Purchase and Accounting apps, no extra apps needed, and supports Odoo 17.0, 18.0 and 19.0 Community and Enterprise.
