Invoice Generator India — GST PDF Invoices for SMBs & Freelancers (2026)

GST invoices for Indian freelancers and SMBs

Registered businesses in India must issue tax invoices with GST breakdowns for B2B supplies. RatPDF provides two paths:

• Create Invoice — single invoices with line items, GST tax name/rate, INR currency, and instant PDF download. No signup on free tier.
• Bulk GST Invoice Generator — CSV upload for full B2B fields (GSTIN, HSN/SAC, place of supply) generating up to 100 PDFs per batch on Business plan.

Parent hub: invoice generator guide. Validate output: GST invoice checker.

When you need a GST tax invoice

Under GST law, a tax invoice is required for taxable supplies above the threshold, and for all B2B transactions where the buyer claims input tax credit (ITC). Your invoice PDF should let the recipient:

• Identify supplier and recipient GSTIN (for B2B)
• See HSN/SAC codes for goods and services
• Verify taxable value, CGST/SGST or IGST split, and total
• Match the invoice to their GSTR-2B reconciliation

Step-by-step: create a single GST invoice

1. Open Create Invoice.
2. Enter From details — legal business name, address, GSTIN (if registered), phone, email.
3. Enter Customer details — name, address, and GSTIN for B2B clients.
4. Add line items — description, quantity, rate. Subtotal calculates automatically.
5. Set Tax name to GST and choose the rate (5%, 12%, 18%, 28%, or custom).
6. Select INR currency and add payment terms, UPI/bank details in Notes.
7. Click Generate PDF — download and email to your client.

For simple B2C invoices or freelancers below GST registration threshold, the main form covers tax name and rate without full HSN fields.

Step-by-step: bulk GST invoices via CSV

CA firms and businesses issuing dozens of monthly invoices should use bulk generation:

1. Open Bulk GST Invoice Generator (Business plan).
2. Download the CSV template with columns for GSTIN, HSN/SAC, place of supply, line items, and tax split.
3. Fill one row per invoice in Excel or Google Sheets.
4. Upload the CSV — RatPDF generates one PDF per row.
5. Download the ZIP of all invoice PDFs.
6. Spot-check 2–3 PDFs with the GST invoice checker before sending to clients.

CGST/SGST vs IGST on your invoice

Tax split depends on place of supply:

• Intra-state (supplier and recipient in same state) — CGST + SGST (each half the GST rate).
• Inter-state — IGST at the full rate.

On the single invoice form, enter the combined GST rate; note the split in the Notes section for B2B clarity. Bulk CSV handles explicit CGST/SGST/IGST columns for automated split on the PDF.

Common scenarios

Freelancer/consultant (registered)

Bill monthly retainers or project milestones in INR with 18% GST on most services. Add UPI ID and bank details for faster payment. Invoice for freelancers.

E-commerce seller

High volume → bulk CSV. Include HSN for goods. Archive PDFs for 6+ years per retention norms.

CA firm billing clients

Generate audit and compliance fee invoices in batch at month-end. Invoice generator for CA firms.

Unregistered small supplier

Issue a bill of supply or invoice without GSTIN if below registration threshold — use tax name field accordingly and consult your CA.

After you generate the PDF

• Email to client — if over 25 MB (unusual for invoices), compress for Gmail.
• Edit later — need to change line items? PDF to Word for invoice or regenerate from source data.
• GSTR-1 filing — invoice data must match what you report; keep PDF archive aligned with books.
• E-invoice IRN — businesses above the e-invoicing threshold need IRN from the Invoice Registration Portal; RatPDF PDF is the human-readable copy alongside IRN QR. See e-invoicing India PDF.
