Invoice software for Indian businesses
Invoice software for India that issues GST tax invoices, stores GSTIN clients, and reports on the April–March year. Not a US sales-tax tool. Not a one-off PDF maker.
Free to start. No credit card. 20 documents a month on Free.
What does invoice software in India have to do?
Invoice software for India has to do more than put a logo on a PDF. It must create a GST tax invoice with seller and buyer GSTIN, HSN or SAC, place of supply, and CGST plus SGST or IGST. It should keep a sequential number series, print amounts in lakh and crore, and close books on the Indian financial year (April–March). One Stop Invoice is invoice software built for that work. It also holds quotations, proforma invoices, debit notes, credit notes, clients, inventory, and expenses, and can email a pack to your Chartered Accountant. It does not generate an IRN on the NIC portal, file GSTR-1, or create e-way bills. Free to start, no credit card, no per-user fee. Free has a watermark and 20 documents per calendar month until you unlock at ₹1,499/year or ₹199/month (GST included).
GST tax invoices
GST tax invoices, not a US invoice template
A US invoicing tool tracks sales tax and a January–December year. Invoice software for India has to split tax from place of supply, keep HSN or SAC on lines, and sit on the Indian FY. That is the product. See GST invoicing for how CGST, SGST, and IGST are applied.
Document set
Quotations, proforma, debit notes, credit notes
Indian businesses do not live on tax invoices alone. Send a quotation, convert it, issue a proforma, then a tax invoice. Debit notes and credit notes stay in the same client and number series. That is software with a ledger, not a downloadable blank PDF.
Clients
Clients with GSTIN, not a contacts list
Each client stores GSTIN, billing address, and place of supply. Format checks run before you save. Outstanding balance and invoice history sit on the same record so you are not exporting a spreadsheet to know who owes you.
Books
Inventory, expenses, and Indian FY reports
Stock and expenses live next to invoices so the year-end pack is not three apps taped together. Reports follow April–March. CA Sync emails a scheduled pack to your Chartered Accountant. Free includes one pack per month.
Connect
API, Shopify, and AI Connect
REST API v1 is on every plan (200 calls a month on Free). Shopify can create GST invoices from orders. AI Connect is available on the same account. None of this is a separate “developer SKU.”
