Seeing this error? The portal blocks a second bill on the same invoice number to prevent duplicates. Below are the common causes and the fixes that resolve it for most users.
Why this happens
- A bill already exists for this invoice number and date.
- A bulk upload was run twice.
- Another user generated it first.
How to fix it
1
Search and reuse
Find the existing bill and use it rather than regenerating.
2
Cancel if wrong
If the existing bill is incorrect, cancel within 24 hours and create a fresh one.
3
Change the document number
A genuinely new consignment needs a new, unique invoice number.
Important
If the problem is on the portal side (maintenance or server load), no browser fix will help — confirm with a second network first.
