Sound familiar?
Invoicing shouldn’t take your evenings
GST checked by hand
You build invoices in Excel or Word, then work out CGST, SGST or IGST yourself and hope the totals match.
“We never got the invoice”
You email a PDF and hear nothing. Two weeks later the client says it never arrived.
Chasing payments yourself
You keep a mental list of who is late and send awkward follow-ups one WhatsApp at a time.

Before you sign up
Fair questions, straight answers
Will my GST be right?
CGST and SGST are split from the place of supply and always add up to the tax charged. IGST for inter-state supplies. Your GSTIN and HSN/SAC codes print on every invoice.
I use Excel, Vyapar or Tally today.
Bring your old invoices over as an Excel or CSV file. They keep their invoice numbers, so your next invoice carries on the same series.
Is my data safe?
Another business cannot see your invoices, clients or payments. Once an invoice is paid it is locked, so it cannot be quietly edited or deleted.
What does it cost to try?
Nothing. It is free to start and you do not need a card to sign up. The 35 free tools on this site need no account at all.
Is InvoiceGennie free?
It is free to start, and you do not need a card to sign up. The 35 free invoice, quotation, receipt and GST tools on this site work without an account.
Will the GST on my invoices be correct?
InvoiceGennie picks CGST and SGST for supplies within your state and IGST for supplies to another state, based on the place of supply. HSN or SAC codes print on each line, and your GSTIN appears on every invoice.
Can I email invoices and send payment reminders?
Yes. Email the invoice to your client with the PDF attached and see when they opened it. Overdue reminders go out 1, 7 and 14 days after the due date once you switch them on. You can also copy a ready-made WhatsApp reminder.
I use Excel, Vyapar or Tally. Can I move my old invoices?
Yes. Upload your old invoices as an Excel or CSV file. They keep their original numbers, so your next invoice continues the same series.
Can I bill monthly retainer clients automatically?
Yes. Set up a recurring invoice once and InvoiceGennie raises it automatically every month.
Does it work on my phone?
Yes. InvoiceGennie works in any mobile browser, and you can install it on your Android phone or iPhone from the download page.
