How to Update Payment Method with Multi Paymode in Odoo POS

Updating payment methods for completed orders is a vital task—especially when customers request a split payment or need corrections after the transaction is finalized. This guide explains how to view payment details, initiate updates, split amounts across different paymode, and confirm changes in your POS system.

Viewing Order Payment Details

Start from the Main Menu, then click Point of Sale. Navigate to Orders → Click Orders. This opens the Orders screen, where all completed orders are displayed.Search for the specific order using the Order Reference, and click on the order to open it.

In the Payments tab, you can view:

• All payment methods used
• The amount paid under each method

For example, the initial payment may show Cash: 2400

Payment Method Update for Paid Orders

The Update Payment Method button appears only when the order status is “Paid.”Clicking this button launches the Payment Method Update Wizard, where all editing takes place.

Initiating the Payment Method Update Process

Inside the wizard, the Record to Update dropdown displays the amounts paid through each payment mode (e.g., 2400 for Cash).

When you select the 3000 amount, the system automatically fills in the:

• Existing Payment Method: Cash
• Actual Amount: 2400

Understanding Actual and Remaining Amounts

• Actual Amount shows the value tied to the selected paymode (e.g., 2400).
• Remaining Amount initially equals the Actual Amount.
• Remaining Amount does not change until you enter new payment amounts.
• If no amount is entered, the Remaining Amount remains unchanged.

Selecting Multiple Payment Methods

In the Payment Method section, click Add a Line to add new paymode.
You can select:

• One paymode
• Or multiple paymode (e.g., Credit card + UPI)

For cash payments, be sure to choose the correct cash terminal option.

Updating Amounts for Each Paymode

Enter the amount you want to assign to each selected paymode.Every time you enter a value, the system automatically recalculates the Remaining Amount.

Formula:
      Remaining Amount = Actual Amount – Entered Amount

Remaining Amount Calculation Example

Actual Amount: 2400
   Step 1: Enter 1000 under UPI
                Remaining Amount becomes 1400
    Step 2: Enter 1400 under Credit Card
                 Remaining Amount becomes 0
This confirms that the full amount has been properly distributed across the selected paymode.

Confirming Payment Updates

Before you finalize, verify that:

• The selected paymodes are correct
• The amounts entered match the intended distribution

When everything is accurate, click Update to save your changes.

Updated Payment Section

After saving, the Payments tab will reflect the revised breakdown.
For example:

• UPI: 1000
• Credit Card: 1400

This confirms the successful update of multiple payment methods for the order.
