What is an invoice generator?

An invoice generator is a tool that helps you build a professional billing document with business details, customer details, line items, tax, and totals — then download or print it. The Web6 invoice generator runs in your browser so freelancers, agencies, consultants, and GST-registered businesses can create invoices without creating an account.

What information an invoice should include

Typical invoices include a document title and number, invoice date, due date, supplier and customer details, item descriptions with quantities and rates, tax breakdown, grand total, payment instructions, and optional notes or terms. Indian GST tax invoices often also include GSTIN, HSN/SAC codes, place of supply, and CGST/SGST or IGST.

How GST invoices work in India

A GST tax invoice records taxable supply with tax components based on place of supply and registration details. This tool calculates common scenarios and labels CGST, SGST, or IGST for convenience. It does not submit e-invoices to government portals and is not a substitute for professional tax advice.

CGST vs SGST vs IGST

For many domestic supplies within the same state, GST is commonly shown as equal CGST and SGST shares. Interstate supplies commonly use IGST. The generator can auto-select based on supplier state and place of supply, or you can override the split when your situation differs.

Invoice numbering guidance

Use a consistent series such as INV-2026-0001 or FY26-27/001. Keep numbers unique within your books. The tool can warn when a number already exists in local history, but you remain responsible for compliance with your accounting process.

Invoice payment terms

Payment terms explain when payment is due and how to pay. Add bank details, UPI ID, IFSC, SWIFT/IBAN, PayPal, or a payment link. Optional payment QR codes on the PDF are for payment convenience — not official GST e-invoice QR codes.

Proforma invoice vs tax invoice

A proforma invoice is often a preliminary bill or quote-style document. A tax invoice is typically used for taxable supplies under GST. Choose the document type that matches your workflow and verify requirements with a qualified professional.

Quote vs invoice

A quote or estimate proposes pricing before work is accepted. An invoice requests payment for goods or services supplied. You can convert a quote workflow into an invoice by changing the document type and dates when ready.

Credit note vs invoice

A credit note adjusts or reverses amounts previously invoiced — for returns, corrections, or allowances. Use the Credit Note document type and confirm tax treatment with your advisor.

Privacy and local browser storage

Drafts and saved invoices stay in this browser. Clearing storage, private mode, device changes, or shared computers can remove data. Browser extensions may also access local data. Export JSON and download PDFs for important records. Do not treat browser storage as your only backup.

Common invoice mistakes

• Missing or duplicated invoice numbers
• Incorrect place of supply or GST split
• Wrong HSN/SAC or tax rate for an item
• Incomplete customer GSTIN or address
• Relying only on browser history without PDF/JSON backups
