The problem
Billing shouldn’t need a spreadsheet and a calculator
Most small businesses invoice from a Word template, work the GST out by hand, find out who has paid from the bank statement, and spend the end of every month hunting down invoices and receipts for their CA.
GST by hand
CGST and SGST or IGST? Which state? Did the halves round correctly? One slip, and a GST invoice has to be redone.
Who has paid?
Part payments, UTRs and UPI references live in the bank statement. What’s still due is anyone’s guess.
The month-end scramble
Invoices in one folder, receipts in another, a spreadsheet for the CA that someone has to rebuild every month.
The cbFinn way
One engine does the maths. You check the preview.
Every figure on a cbFinn invoice is worked out on the server, by the same calculation every time, and the A4 preview you see while you type is exactly the page your client receives.
- IGST, or CGST + SGST, decided from the place of supply.
- Every rupee held in whole paise: the halves always add up to the total tax.
- Your numbering, your bank details and your signature on every page.
- Issued invoices can’t be deleted or renumbered, only cancelled with a reason.
