Quotes your accountant will not send back

Correct GST, every time

Tax is worked out per line item from the HSN or SAC code, and CGST plus SGST or IGST is chosen from the buyer and seller states.

Professional PDFs

Your logo, GSTIN, bank details and terms on every quotation, produced on the server with no template fiddling.

Send from the platform

Email the quotation or send it on WhatsApp directly from the lead, and see when it was delivered.

Versioning and status

Draft, Sent, Accepted or Rejected, with version history so you always know which quote the customer is looking at.

Paise-accurate, audit-ready

Amounts are held in paise with fixed-point arithmetic, so totals match to the rupee and your accountant can file straight from the PDF.
