Three documents a month on the free plan.

Real output A whole WhatsApp thread: the owner asks the GST rate, BillSathi answers, lists the items it understood, offers to add the UPI QR code, and sends back the finished invoice PDF. The quotation that came out: Sharma & Sons letterhead with GSTIN, three line items with HSN codes and rates, IGST at 18 per cent, a grand total of 63,720 rupees, the amount in words, terms, and a UPI QR block.

It shows you what it heard before it makes anything.

BillSathi never makes a bill quietly. It restates the items, quantities, rates, GST split and customer details, then waits for your approval.

Anything it worked out for itself — the tax rate from the item, the customer's state from their address, the HSN code — is marked as inferred so your eye lands on exactly what to check. One tap and it is yours. One correction and it fixes it in the same chat, keeping the same document number.

You approve every document Corrections keep the number

The old way took thirty minutes.

Same two items, same customer, same GST. One of these needs a laptop.

Before

  • Go home, open the laptop and find the right sheet
  • Type every line and calculate the GST by hand

See all questions
Do I need to install anything?
No. WhatsApp on your phone is the entire product. There is no app install, no signup form and no account creation — just message the number to start.
Which documents can it make?
Quotations, GST tax invoices, delivery challans, purchase orders, receipts and job work bills. All six from voice, photo or text.
Can I run more than one firm?
Yes, on the Business plan. Each firm keeps its own GSTIN, logo, terms and PDF template on one WhatsApp number.
How does it know my rates?
It learns them from your own past bills. After a few documents it remembers customer-specific rates and asks “same as last time?” instead of making you say them again.
Is there a web dashboard?
Not yet — coming soon. Every document you create on WhatsApp is saved so your full history is ready when it launches.
What happens to my data?
It stays yours. Built for India's DPDPA 2023: your documents and customer lists are never sold, never shared and never used to market to your clients. Voice notes and photos delete after 30 days, and one message deletes your account. The DPDPA disclosure has the full details.
