Frequently Asked Questions
What fields go on a GST-compliant invoice?
Supplier and buyer GSTIN, invoice number and date, HSN/SAC codes per line item, taxable value, CGST+SGST (intra-state) or IGST (inter-state) breakup, and place of supply. The generator has no dedicated GST fields — type GSTIN, HSN, and tax splits into the business, client, item, and notes fields, and verify compliance yourself.
How should I number my invoices?
Use a continuous yearly series like INV/25-26/001 — tax authorities require sequential, gap-free numbering per financial year. Start a fresh series each April.
Can I add my logo and business details?
Business name, address, and contact blocks are editable text at the top of the invoice. There is no logo upload — keep a text header.
PDF or text output — which to send?
Use Print / PDF for emailing to clients and record-keeping (fixed layout, prints cleanly); use the text download when the client needs to copy line items.
Is my client and billing data stored?
No. Everything renders locally in your browser. No client names, amounts, or GSTINs are transmitted or stored.
What does the starter draft add up to?
The two sample lines (1 × $1,500 plus 1 × $120) subtotal $1,620.00, and with the 0% default tax the total is $1,620.00. Tax is one flat percent on the subtotal — set 18 for GST-style math — and the text export downloads under the invoice number.
