For CA and accounting firms

Your clients send bills on WhatsApp. We get them into Tally.

A WhatsApp assistant collects bills and bank statements from your clients. AI reads them. A bot drafts the entries in Tally. Your team checks and approves. Nobody re-types.

How a monthly document chase could look. The client and numbers are made up.

Sound familiar?

Month after month, the same work by hand.

  1. 01

    Chasing every client for documents

    Your staff send the same WhatsApp reminder, one client at a time, every month.

  2. 02

    Re-typing bills and statements

    Purchase bills, sales bills and bank lines get typed into Tally by hand.

  3. 03

    Matching takes hours

    Matching bank lines and GST data to the books eats days your team doesn't have.

  4. 04

    Due dates land together

    GST, TDS and ITR work all peak at once, and follow-ups fall behind.

What we set up

From your client's phone to a checked Tally entry.

Four steps, connected. Your team only steps in to check and approve.

  1. Step 1 · WhatsApp

    Documents come in

    The assistant asks each client for this month's documents and says thanks when they arrive.

  2. Step 2 · AI

    AI reads them

    Bills and statements: party, GSTIN, date, amount and tax. Bank lines get matched to ledgers.

  3. Step 3 · Bot

    Entries drafted in Tally

    A bot creates the vouchers in Tally and marks each one so your team can check it.

  4. Step 4 · WhatsApp or call

    The follow-up

    Something missing? The assistant reminds the client on WhatsApp, then calls if needed.

Other jobs we can take on

  • Bank statement entries into Tally
  • Purchase and sales bill entries
  • Matching your purchase register with GSTR-2B
  • Due-date reminders to all your clients on WhatsApp
  • Fee reminders and payment links for your own invoices
  • Collecting new clients' PAN, GST and KYC documents

Questions

What CA firms ask us.

Does it work with Tally Prime?

Yes. If you're on an older version of Tally, we'll check your setup on the first call before promising anything.

Will clients mind talking to an assistant?

Messages go out in your firm's name and in your office's tone. Clients can reply "call me" at any time to reach a person at your firm.

What about client confidentiality?

Client data stays in your Tally and your accounts. We sign a confidentiality agreement before we see any of it, and the bots only get the access a task needs.

Does this replace my staff?

No. It takes the typing and chasing off them, so they can spend their time on review, advice and clients.

What does it cost after the pilot?

A monthly plan of ₹15,000, ₹30,000 or ₹50,000, depending on how much work it covers, plus your own tool costs. See pricing.

Try it on one month's bills.

Book a 30-minute call. We'll pick one task, measure it for a week, and write down the result we'll aim for.
