GST invoicing for Indian businesses

Quote. Invoice.Get paid.

Your client accepts a quotation from a link. It becomes a GST tax invoice with a legal number. They pay by UPI, straight into your account. Your suppliers' bills and your bank statement sit on the same books, and your CA gets the reports for GSTR-1.

01The thread

One thread from quote to paid.

Every document knows where it came from. The invoice carries its quotation's number; the payment carries the invoice's.

03GST, done for you

The tax is decided, not picked.

Nobody on your team chooses a tax type from a dropdown. The place of supply decides it, the item carries its rate, and every field the law asks for is printed without anyone remembering to.

Inter-stateDifferent state — IGST, the whole rate.

Taxable value: 90,000.00
IGST 18%: 16,200.00

The total is the same either way. What changes is who collects the tax — both states, or the Centre.

04Who it's for

Made for businesses that invoice every week.

The part between the quote and the payment, done properly, for the people who do it themselves, and the accountant who checks it.

05Price list

Three plans, billed monthly, plus GST.

They differ in seats, invoices a month and what your accountant gets. Quotations are never counted, and Viewer seats are free.

Grow a unit at a time. Extra seats and blocks of 100 invoices a month, added when you need them.
A custom plan from the same price book, when no plan matches.
