Features

Everything your business needs. All on WhatsApp.


01The core idea

Your business assistant lives on WhatsApp.

No app to download. No software to learn. Just send a message — voice, photo, or text — and BillSathi handles the rest. Professional documents ready in minutes.

02Input methods

Three ways to create a document.

Use whichever fits the moment.

🎤

Speak in Hindi or English

Send a voice note describing your items, quantities, and rates. Talk the way you normally talk — Hindi, Hinglish, or English.

Example"50 bag cement 380 ka, 200 kilo sariya 65 ka, party Sharma Hardware"
📷

Snap a photo

Already written it down on paper? Just photograph it. BillSathi reads handwritten lists and printed text both.

Use caseSuppliers' bills, paper challans, your own pad — any photo BillSathi can parse.

Type it directly

Prefer to type? Just send a text message. Any format, any language. BillSathi understands.

Use case"INV for Patel — 12 ply sheets 850/each, party from Gujarat"

03Document types

Six document types. One WhatsApp number.

All GST-compliant. All branded with your logo.

04GST engine

GST calculated automatically. Always correct.

BillSathi knows your state and your client's state. It applies the right tax split every time. You never have to think about GST again.

  • Same state → CGST + SGST
  • Different state → IGST
  • Rates supported → 0%, 5%, 12%, 18%, 28%
  • HSN codes filled in where applicable
  • Monthly + quarterly summaries on demand

05Your brand on every PDF

Professional PDFs with your name on them.

Every document carries your business identity.

  • Your logo on every PDF
  • Business name and address
  • Your GSTIN
  • Bank details (optional)
  • Your terms and conditions
  • Your signature and seal (Pro plan)
No watermark

Business plan and above — your documents look like they came from your own software, not ours.

06Confirmation before every PDF

BillSathi always confirms before generating.

Before any PDF is created, BillSathi shows you exactly what it understood — items, quantities, rates, client name, GST split, total. You approve it. Only then the PDF is generated.

No surprises. No wrong documents sent to clients.

08Smart memory

BillSathi remembers your clients and rates.

Once you've created a document for a client, BillSathi remembers their details.

👤

Client memory

Name, address, state, GSTIN — all remembered. Next time, just say the client name. No need to repeat the details.

Rate memory

Set product rates once. BillSathi uses them automatically the next time you mention the item — you can override anytime.
