E invoice software automates the creation of GST-compliant invoices that include all mandatory details like the supplier’s GSTIN, HSN/SAC codes, tax amounts, and the Invoice Reference Number (IRN) with a QR code for B2B transactions above the ₹5 crore turnover threshold. This software reduces manual entry, ensures rule compliance, and integrates with GST returns and e-way bills.
Why this comes up / what goes wrong
Small businesses in India often struggle with manual invoice creation using spreadsheets, Tally, or bill books. This leads to errors in GST invoice particulars required by Rule 46, such as missing GSTINs, incorrect tax splits (CGST/SGST/IGST), or absent HSN/SAC codes. For businesses with aggregate turnover over ₹5 crore, e-invoicing is mandatory for B2B supplies, requiring an IRN and a QR code generated through the NIC portal. Without software, uploading JSON files and managing cancellations manually is time-consuming and error-prone. Duplicate data entry for e-way bills adds to the workload. E invoice software streamlines these processes, ensuring compliance and saving time.
Step-by-step
- Check your eligibility for e-invoicing: Confirm if your aggregate turnover exceeded ₹5 crore in any financial year from 2017-18 onwards; if yes, you must issue e-invoices for B2B supplies from 1 August 2023 [source: einvoice-threshold-5cr/einv-5cr-from-2023-08-01].
- Choose software that supports GST invoicing and e-invoicing: Verify it can create invoices with CGST/SGST or IGST splits, include HSN/SAC codes from the customer's GSTIN, and generate IRN and QR codes automatically.
- Create your invoice: Enter supplier and recipient details, description, quantity, unit, taxable value, and applicable tax rates. Ensure the invoice matches Rule 46 requirements, including unique serial numbering and signatures [source: cgst-rule-46/rule46-particulars].
- Generate the e-invoice: For B2B invoices above the threshold, the software should send invoice data to the NIC portal and retrieve the IRN and signed QR code automatically.
- Handle NIC rejections and cancellations: If the NIC rejects the e-invoice, review the error code, correct the invoice, and retry. Manage cancellations within the permitted window directly from the software.
- Raise the e-way bill: Use the same invoice record to create an e-way bill, avoiding duplicate entry of consignment details.
- File your GST returns: Use the invoice data to prepare GSTR-1 and GSTR-3B, ensuring the e-invoice details are consistent with your filings.
Example (fictional figures)
Suppose "ABC Traders" issues a B2B invoice on 15/07/2023 for goods worth ₹1,00,000 with a GST rate of 18% (CGST 9%, SGST 9%).
- Taxable value = ₹1,00,000
- CGST = ₹1,00,000 × 9% = ₹9,000
- SGST = ₹1,00,000 × 9% = ₹9,000
- Total tax = ₹9,000 + ₹9,000 = ₹18,000
- Invoice total = ₹1,00,000 + ₹18,000 = ₹1,18,000
The software generates the invoice with all required details, sends it to the NIC portal, obtains the IRN and QR code, and embeds them in the PDF. The e-way bill is raised from the same invoice, so consignment details are not re-entered.
Common mistakes
- Missing or incorrect GSTINs: Always verify the supplier’s and recipient’s GSTINs from official sources to avoid errors. Use software that auto-fills these from GSTIN.
- Incorrect tax splits and rates: Manually calculating CGST/SGST/IGST can cause mistakes; use software with automated tax calculation.
- Not generating IRN or QR code for eligible invoices: Businesses over ₹5 crore turnover must e-invoice B2B supplies; failing to do so leads to non-compliance.
- Duplicate data entry for e-way bills: Raising e-way bills separately wastes time; choose software that creates e-way bills from the invoice.
- Ignoring NIC rejection codes: If the NIC portal rejects an invoice, review the error and correct it promptly.
- Using inconsistent invoice numbering: Rule 46 requires unique serial numbers per financial year; maintain this strictly.
