QUICK ANSWER
The e-invoice could not be generated because the customer’s GSTIN was entered incorrectly in the customer master and remained incorrect in the transaction-level Bill To and Ship To details.
Correcting and verifying the GSTIN in all three locations—the customer master, Bill To details, and Ship To details—resolved the validation exception. After saving the corrected information and regenerating the e-invoice, the Invoice Reference Number was created successfully.
Problem description
During e-invoice generation, the transaction appeared in the exception report with the following message:
GST Rate Details are overridden in transaction, HSN/SAC Details are overridden in transaction, GST Registration Details of the Party are invalid or not specified.
In this case, the invoice amount was displayed correctly, but the accounting software could not process the transaction for e-invoice generation because the customer’s GST registration information was invalid.
Investigation revealed a typing error in the customer’s GSTIN. The incorrect GSTIN was present in more than one location:
- The customer or party master
- The transaction’s Bill To details
- The transaction’s Ship To details
Correcting only the customer master was not sufficient because the existing invoice continued to contain transaction-level copies of the old information.
Why this e-invoice error occurs
An accounting or ERP application generally prepares structured invoice data and sends it to an authorised Invoice Registration Portal. The portal validates mandatory information before generating an Invoice Reference Number.
For a registered business-to-business recipient, this information includes the recipient’s GSTIN and relevant billing details. Depending on the transaction, separate dispatch and shipping information may also be included.
The exception can occur when:
- The customer’s GSTIN contains a typing mistake.
- The GSTIN is incomplete, blank, inactive, cancelled, or not valid for the transaction.
- An incorrect registration type is selected in the customer master.
- The GSTIN in the customer master differs from the GSTIN stored in the invoice.
- Old Bill To or Ship To information remains in an invoice created before the master was corrected.
- The wrong state, address, or place-of-supply information is associated with the GSTIN.
- A transaction-level override contains incorrect party information.
A GSTIN follows a defined 15-character structure, but passing a basic format check does not prove that the GSTIN belongs to the intended customer or that the registration is active. The taxpayer details should be verified through an official GST or authorised IRP search facility.
Resolution
Step 1: Verify the customer’s GSTIN
Obtain the correct GSTIN from a reliable source, such as:
- The customer’s GST registration certificate
- A recent verified tax document
- The official GST taxpayer search
- An authorised Invoice Registration Portal’s GSTIN search
Confirm the following details:
- Legal business name
- Trade name, where applicable
- GSTIN
- Registration status
- State or jurisdiction
- Registered address
Do not rely only on a GSTIN received through an informal message or copied from an unverified document.
Step 2: Correct the customer master
Open the customer or party master in the accounting application and review the GST registration section.
Correct the following fields where necessary:
- GST registration type
- GSTIN
- Legal or mailing name
- Address
- State
- PIN code
- Country
Save the corrected customer master.
The exact menu names vary between accounting applications and versions. Users should follow the product’s supported procedure for altering a customer or party record.
Step 3: Reopen the affected invoice
Open the invoice listed in the e-invoice exception report.
Do not assume that updating the customer master automatically changes an existing invoice. Many applications preserve a snapshot of the customer information that was available when the invoice was created.
Review the party details stored inside the invoice itself.
Step 4: Correct the Bill To details
Open the Bill To or buyer-details screen and confirm that it contains the correct:
- Customer name
- GSTIN
- Address
- State
- PIN code
- Place of supply, where applicable
Replace the incorrect GSTIN and save the changes.
Step 5: Correct the Ship To details
Open the Ship To, consignee, or shipping-details screen and verify the destination information.
Correct the GSTIN if the shipping location is registered under a GSTIN and the existing value is wrong.
The Bill To and Ship To GSTINs should not automatically be made identical. They may legitimately differ when the goods are billed to one registered person or location and delivered to another. Use the GSTIN and address that accurately represent the actual transaction.
Step 6: Review the remaining exceptions
The exception report also indicated that the GST rate and HSN/SAC details had been overridden in the transaction.
An override is not necessarily an error. However, it means the invoice-level values differ from the values configured in the relevant master records. Verify that:
- The selected GST rate is appropriate for the goods or services.
- The HSN or SAC code is correct.
- The taxable value and tax amounts are correct.
- The place of supply is accurate.
- The transaction uses IGST or CGST and SGST appropriately.
- Any manual override is intentional and authorised.
Do not remove a valid override merely to clear a warning. Tax classification should be reviewed by the organisation’s accountant or GST professional when uncertain.
Step 7: Save and regenerate the e-invoice
After correcting all relevant locations:
- Save the invoice.
- Return to the e-invoice or exception report.
- Refresh or reprocess the transaction, if required by the application.
- Submit the invoice for e-invoice generation again.
- Confirm that an IRN and signed QR code are received.
In the reported case, correcting the GSTIN in the customer master, Bill To details, and Ship To details cleared the exception and allowed the e-invoice to be generated successfully.
How to verify that the issue is resolved
Successful processing should normally produce:
- An Invoice Reference Number
- An acknowledgement number and date
- A digitally signed e-invoice response
- A signed QR code
- A successful or generated status in the accounting application
Open the generated e-invoice and confirm that the recipient, billing, and shipping information is correct. Successful IRN generation does not remove the organisation’s responsibility to ensure that the underlying invoice data is accurate.
The authorised IRP provides facilities for checking e-invoice status and validating signed QR-code information.
Important precautions
Do not guess or reconstruct a GSTIN
A GSTIN is a tax identifier, not a value that should be inferred from a business name. Always verify it using official records or documentation supplied by the customer.
Do not overwrite legitimate Ship To details
A different delivery address or GSTIN may be correct in a Bill To–Ship To transaction. Confirm the commercial arrangement before changing it.
Review existing invoices separately
A master correction may apply only to future transactions. Existing invoices can continue to hold the old GSTIN until their transaction-level details are corrected.
Avoid uncontrolled changes after IRN generation
Once an IRN has been generated, do not simply alter the local invoice in a way that makes it inconsistent with the registered e-invoice. Follow the applicable cancellation, credit-note, debit-note, or amendment process and consult a GST professional when required.
Restrict access to GST masters
Only authorised users should be allowed to change customer GST registration details. Changes should be supported by documentation and recorded in an audit trail where the software provides one.
Preventing the error in future transactions
Organisations can reduce GSTIN-related failures by implementing the following controls:
- Verify every GSTIN before creating or updating a customer master.
- Use copy and paste carefully, checking for missing or extra characters.
- Match the legal name and state with official taxpayer details.
- Avoid unnecessary invoice-level overrides.
- Review Bill To and Ship To information before saving an invoice.
- Revalidate customer GST details periodically.
- Restrict master-data modification rights.
- Maintain evidence supporting GSTIN changes.
- Test e-invoice generation before bulk submission.
- Train billing users to distinguish between billing and shipping registrations.
Benefits of maintaining accurate GST details
Accurate customer GST information provides several operational benefits:
- Reduces e-invoice validation failures
- Prevents delays in IRN generation
- Improves invoice and tax-reporting accuracy
- Reduces manual corrections and repeated submissions
- Helps customers process their invoices correctly
- Improves the reliability of accounting master data
- Supports better reconciliation and audit readiness
- Reduces the risk of using the wrong recipient or destination details
FAQ
Frequently asked questions
Why did updating the customer master not immediately solve the error?
The existing invoice may have retained the old GSTIN in its Bill To or Ship To details. These transaction-level values must also be reviewed and corrected.
Where should the customer GSTIN be checked?
Check the GSTIN in the customer master, the invoice’s Bill To details, and the Ship To or consignee details. Also verify the number through an official GST or authorised IRP search service.
Must the Bill To and Ship To GSTIN always be the same?
No. They can differ in a legitimate Bill To–Ship To arrangement. The information must reflect the actual buyer, recipient, and delivery destination.
Does a 15-character GSTIN automatically mean it is valid?
No. A value may have 15 characters and still be mistyped, inactive, cancelled, or associated with another taxpayer. Confirm its official registration details.
Are overridden GST rates and HSN/SAC details always errors?
No. An override may be intentional, but it should be reviewed. Confirm that the selected rate and HSN/SAC classification are correct before generating the e-invoice.
What should I do if the GSTIN is correct but the exception continues?
Review the registration type, state, PIN code, place of supply, Bill To and Ship To records, and any transaction-level overrides. Refresh the exception report and consult the software provider’s documentation or support team if the issue remains.
Can I edit the invoice after an IRN has been generated?
A local edit can make the accounting record inconsistent with the registered e-invoice. Use the legally applicable cancellation or adjustment process and obtain professional guidance when necessary.
How can this issue be prevented for multiple invoices?
Correct and verify the customer master first, then identify existing invoices that retained the old GSTIN. Review each affected transaction before resubmitting it; do not apply an unverified bulk replacement.
FINAL RECOMMENDATION / CONCLUSION
When an e-invoice reports that the party’s GST registration details are invalid or unspecified, verify the customer’s GSTIN against official records and inspect every location from which the invoice obtains party information.
Correct the customer master as well as the Bill To and Ship To details stored in the affected invoice. Review any GST-rate or HSN/SAC overrides, save the transaction, and generate the e-invoice again. This complete review resolved the reported issue and resulted in successful IRN generation.
