Development » Invoice Generator

The system allows the due date to be entered before the invoice date when the user enters the due date first and then sets the invoice date. This results in invalid date logic, which may lead to errors in invoice generation.

Steps to Reproduce:

1. Open the "Invoice" section of the Online Invoice Generator.
2. Set the due date (e.g., January 20, 2025) before entering the invoice date.
3. Enter the invoice date (e.g., January 23, 2025).
4. Observe that the system accepts the due date, which is earlier than the invoice date.

Expected Behavior:
The system should validate and restrict the due date to always be on or after the invoice date, regardless of the order in which the dates are entered.

Actual Behavior:
The system does not validate the due date properly when entered first, allowing an invalid date sequence.

Impact:
This issue may cause confusion or errors in invoice processing, as the due date cannot logically precede the invoice date.
