Payment Due Date difference in Days for Invoice, Bill, Credit Note, Receipt, Refund

OMAX INFORMATICS

Overview

The Payment Due Date Difference module helps analyze the number of days between the invoice/bill payment date and its due date. With this module, Accountants can view the Due Date - Payment Date Difference In Days directly inside Invoices, Bills, Credit Notes, Debit notes, Sale Receipts and Purchase Receipts. Additionally, a reporting wizard makes it easy to generate Excel reports with filtering.

Key Features

  • Track the difference in days between Payment Date and Due Date.
  • Due Date - Payment Date Difference In Days tab available in:
    • Invoices & Bills
    • Credit Notes & Debit Notes
    • Sales Receipts & Purchase Receipts
  • Whenever a payment is registered, an entry is automatically added to the document’s Due Date - Payment Date Difference In Days tab, capturing the difference (Due Date − Payment Date).
  • Excel Report for detailed payment analysis with filters: Start/End Date, Move Type, Company, Customers/Vendors, Invoices/Bills.
  • Seamless integration with Odoo Accounting flows. Save accountant time with automated difference calculations

How It Works

Let's execute the flow.
Case 1: Sigle Due Date for the the invoice and No Payment Terms assigned.


Pay this Invoice.

Invoice Payment Status assigned to PAID and Amount due is 0.00 as per default Odoo.

Due Date - Payment Date Difference In Days

When a payment is registered, the system automatically adds a new line in Due Date - Payment Date Difference In Days tab.
It displays the Payment Date, Due Date, Paid Amount, and Difference in Days — all in read-only mode.
The difference is calculated as:
Due Date − Payment Date = Difference in Days
For example, this invoice shows a 38-day payment delay.

Case 2: Multiple Due Dates & Multiple Payments for an Invoice

  • Customer Invoice: INV/2025/00001
  • Total Amount: $1,000.00
  • Payment Terms: 30% Now, Balance 60 days
Based on the payment terms, the installments are scheduled as follows:
  • Installment 1: $300.00 due on 06/01/2025
  • Installment 2: $700.00 due on 07/31/2025

1st Payment Received.
  • Date: 06/15/2025
  • Amount: $360.00
Installment Allocation
  • 1st Installment ($300.00 due on 06/01/2025):
  • From the total paid amount ($360.00), $300.00 is allocated to this installment. The remaining $60.00 is carried forward to the 2nd installment.
    Difference in Days: 14 days delay (06/01/2025 → 06/15/2025).
  • 2nd Installment ($700.00 due on 07/31/2025):
    The remaining $60.00 is treated as an advance payment.
    Difference in Days: -46 days (early payment), since payment was received on 06/15/2025 while due date is 07/31/2025.

2nd Payment Received.
  • Date: 08/13/2025
  • Amount: $640.00
  • Difference in Days: 13 days delay (07/31/2025 → 08/13/2025).
