How do I update customer data after bill generation without canceling the bill if IRN is not generated?
Factech allows admin users with billing and customer update rights to modify customer details in a generated invoice only if the IRN (Invoice Reference Number) has not been generated. This is because the invoice hasn’t yet been pushed to the GST e-invoicing system. You can update the following fields for the unit or tenant, as bills may be generated for either owner or tenant.
- Customer Name
- Address
- GSTIN
- State Code must be a numeric value between 01 and 38.
- Place of Supply (POS) must also be a numeric value between 01 and 38.
- Location
- Pin Code
- Is Business
Steps to update unit and tenant details:
- Go to Customer menu → Search Unit.
- Select the unit → Click Search → Click View Unit Details.
- To update unit/owner info: click Edit, update fields (GSTIN, Pin, etc.), then click Update button.
- To update tenant info: click Edit, fill in details, and click Update.
Steps to update user details in a generated invoice:
- Go to Bill menu → Search Bill.
-
Select the Unit and Bill Plan, then click on Search.
-
-
Select the bill and click Update Customer Data.
- After updating, click Regenerate PDFs to generate all updated invoices.
Clicking Regenerate PDF under Action will generate only that single invoice PDF.
Important Note: – Once the IRN is generated, customer data in the invoice cannot be updated. As per GST rules, the invoice can be cancelled within 24 hours of creation, and a new invoice with a different number can be generated.
