Applying Cash Rounding to a GR Bill in Odoo
When you receive a vendor bill and notice that the vendor has rounded off the total amount, but the corresponding GR Bill still shows the exact amount without rounding, you can apply cash rounding to align both amounts.
To do this, go to the Other Info tab in the GR Bill and select the appropriate Cash Rounding Method (Example: CASH ROUNDING) using the drop down option.

The selected cash rounding method should be configured with the following settings:
- Rounding Precision: Set as 1
- Rounding Strategy: Choose the Add a rounding line (this will add a separate line to the bill for the rounding adjustment).
- Rounding Method: Select the Half Up method.

While the selection of rounding method remains the same, but the rounding depending on the decimal values. Here are two scenarios to demonstrate how it works:
Scenario 1: Rounding Up
- GR Bill Total Amount: ₹1523.56 , Vendor Bill Total Amount: ₹1524
- After applying the cash rounding method, the system rounds the amount up by ₹0.44
- Rounding: ₹0.44 -> applied to the GR Bill
- Total Amount becomes ₹1524.
Scenario 2: Rounding Down
- GR Bill Total Amount: ₹9,881.44 , Vendor Bill Total Amount: ₹9,881
- After applying the same rounding method, the system rounds the amount down by ₹0.44.
- Rounding: ₹-0.44 -> applied to the GR Bill
- Total Amount becomes ₹9,881.

In both scenarios, the rounding method remains the same, but the final result differs due to the decimal values.
Completing the GR Bill
After applying the appropriate rounding, you need to enter the bill amount, taxable amount, and tax amount in the GR Bill. Once all the details are entered, simply confirm the GR Bill to complete the GR Bill and ready for further processing, ensuring that the total matches the vendor’s rounded amount and is accurately recorded.
