1. Creating Payment Journals Start by creating two payment journals in Odoo: - **POS Journal**: for card payments via register A. - **Cash Journal**: for cash payments, used by all registers. Go to *Accounting > Configuration > Journals* and define the payment types, associated accounts, and bank reconciliation methods. 2. Configuring Payment Methods In the Point of Sale module, configure the payment methods: - Associate **"Card (POS)"** only with register A. - Associate **"Cash"** with all registers. This allows Odoo to know which payment method is available at each terminal. Go to *Point of Sale > Configuration > Points of Sale* and adjust the payment methods for each register. 3. Assigning Registers to Cashiers Assign each register to its cashier in Odoo to track sales by user. - Register A → Cashier A (with payment terminal) - Registers B and C → Cashiers B and C (without payment terminal) This allows you to track sales and payments by individual. You can manage this in *Users > Preferences > Point of Sale*.
