Consolidated invoicing, in-POS settlement, and bill splitting
Combine paid orders into one invoice, collect payments on open customer invoices, and split bills by guest or group, all without leaving the POS register.
The problem
Cashiers can invoice a single POS order, but Odoo offers no way to combine several paid orders into one invoice for a business customer, settle a customer's open invoices at the till, or split a bill beyond a basic product and quantity divide. Staff are forced into the accounting backend mid-queue, and accountants reconcile cash and bank takings against invoices after the fact.
The solution
POS Multi Invoice adds all three workflows to the register: consolidate multiple paid orders into one invoice, settle a customer's open invoices with cash or bank clearing, and split a bill by guest or group with tip allocation, each with a full audit trail and session-close reconciliation.
Everything the register needs
Every capability below is implemented in the module.
Consolidated multi-order invoicing
Select multiple paid POS orders for a customer and combine them into a single posted invoice, with automatic order status updates and rollback on cancellation.
Conditional invoice rules
Configure automatic invoicing eligibility by customer, payment method, register, and minimum amount, with per-register overrides.
In-POS invoice settlement
Search a customer by name or VAT, view their open invoices as cards with live balances, and collect payment right at the register.
Lump-sum auto-distribution
Enter a single amount and let it apply oldest-first across a customer's open invoices, with clear remaining-balance tracking.
Cash/bank clearing & reconciliation
Settlements post an account payment reconciled to the selected invoices, keeping cash and bank journals correctly distinct.
Invoice-payment audit trail
Every settlement is logged with amount, method, timestamp, and user, with a manager Void action available for corrections.
Session-close reconciliation
The closing popup adds a dedicated cash/bank/total section for invoice payments so the drawer reconciles on the first try.
Flexible bill splitting
Split the active cart evenly or by custom amount among guests, with tip allocation and a unified-bill option.
Payment receipts & traceability
Print or email a dedicated invoice-payment receipt, and trace every consolidated invoice back to its source POS orders from a smart button.
How it works
Select orders or customer
From the POS or backend, pick paid orders to consolidate or search a customer to settle.
Choose invoices
Review open invoices as cards showing balance and status, or confirm the orders included in a consolidated invoice.
Distribute amount
Enter a payment amount for auto oldest-first distribution, or confirm the bill split by guest or group.
Confirm & reconcile
Post the invoice or payment, print or email the receipt, and see the totals reflected at session close.
