For bulk e-invoice generation or API integration, additional registration for API access may be required. **Step 3: Choose Compatible Invoicing Software** Taxpayers can use their preferred accounting or [**invoicing software**](https://busy.in/accounting-software/invoicing-and-gst-billing/) in India as long as it supports the prescribed e-invoice format. Options include – - Integrated accounting systems - Utilities to convert invoices into JSON files, such as Excel tools or mobile apps - Offline tools are provided by the e-invoice portal **Step 4: Generate an e-invoice with Correct Details** Invoices should include mandatory details, such as – - [**GSTINs**](https://busy.in/gst/gstin-everything-you-need-to-know/) of the supplier and recipient - Invoice number, date, and value (taxable and gross) - Line item details, including [**HSN codes**](https://busy.in/hsn/) These details ensure proper validation by the Invoice Registration Portal (IRP). **Step 5: Upload e-Invoice to the GST Portal** Once the invoice is prepared, upload the [**JSON file**](https://busy.in/gst/e-invoice-format-json-file-schema-template/) to the IRP. This can be done manually via offline tools or through API integration. For bulk uploads, taxpayers can use tools available on the portal under the Help section. **Step 6: Receive IRN from the GST Portal** The IRP validates the uploaded data, checks for duplication, and generates a unique [**Invoice Reference Number**](https://busy.in/gst/gst-eway-bill-invoice-reference-number-irn/) (IRN) using a hash-generation algorithm. The portal automatically generates one if the taxpayer doesn’t pre-generate an IRN. **Step 7: Download the e-invoice PDF with IRN** After validation, the IRP digitally signs the invoice and attaches a QR code containing key details, including – - GSTINs of both supplier and recipient - Invoice number and date - Total invoice value and HSN of the main item - The unique IRN Taxpayers can download the signed JSON file and convert it into a readable PDF. **Step 8: Include IRN on Subsequent Documents** The IRN and QR code must be integrated into all subsequent documents and shared with the buyer.

Avoid simultaneous requests, wait for the IRN, and resend only if it has not been received. **– Incorrect Tax Allocation for Intra-State Transactions:** IGST is applied instead of CGST and SGST. Verify State codes and use CGST/SGST when they match; flag intra-state transactions for IGST when applicable. **– Invalid HSN Code:** Validation errors arise from incorrect HSN codes. Cross-check on the e-invoice portal or confirm with the help desk. **– Mismatch in Taxable Values:** This happens when the total taxable value doesn’t match the line item sums. Ensure total taxable value equals the sum of all line items. ## Using BUSY for e-invoicing BUSY automates [**e-invoice**](https://busy.in/gst/e-invoice/) and IRN generation, reducing errors and ensuring GST compliance.
