Every bill, in the book.
Every statement, checked.

BillBahi reads your bank alerts, bills and card statements straight from email, matches each bill to the payment it belongs to, and audits every statement the day it arrives, so your CA gets clean books instead of a shoebox.

How it works

Your inbox already has the books. BillBahi writes them up.

STEP 1 · CONNECT

Link Gmail or Outlook, or forward

Connect your mailbox read-only, or forward bank alerts, bills and statements to your private BillBahi address. Only emails that look like transactions, bills or statements are processed.

STEP 2 · CAPTURE

Transactions and bills land in your ledger

Card and UPI alerts become entries. Invoices, receipts and e-tickets are stored and read automatically: vendor, amount, GST and GSTIN. Each bill is suggested against its payment for you to accept or reject.

STEP 3 · AUDIT

Every statement reconciled on arrival

When a card or bank statement arrives (password-protected is fine), every line is read, checked against your ledger, and audited: duplicates, missing bills, GST gaps and totals that don't add up.

Features

Built around how Indian businesses actually keep books

Email capture

Gmail and Outlook connections (read-only) plus a private forwarding address. Bank alerts from HDFC, ICICI, SBI Card, Axis, IDFC FIRST, Kotak, Amex and more.

Bills read for you

PDFs, photos, scans and e-receipts in the email body. Vendor, invoice number, date, total, GST and supplier GSTIN are pulled out automatically.

Suggested matches

Each bill is proposed against the right payment by amount, date and vendor. You accept or reject; rejected pairs never come back.

Statement audit

Bank-total reconciliation, duplicates, missing bills, cash over ₹10,000 (Sec 40A(3)), GSTIN checks, foreign services under reverse charge, capital vs revenue.

Duplicate guard

The same spend arriving as an alert, a statement line and a bill is recorded once. Re-sent statements are recognised and skipped.

Purpose & category

Business or personal, category, one-line purpose and capital-asset flag on every entry. BillBahi learns your vendors as you go.

CA-ready export

Excel workbook by financial year (April–March): ledger, category and month summaries, quarter totals, missing bills, open issues, and a zip of bills named by reference.

Your CA, online

Invite your CA with the access level you choose. They review, categorise and run audits without you emailing a single spreadsheet.

Phone first

Photograph a bill, scan it, or pick it from Drive. Every screen works on a phone.

Questions

Before you sign up

Which emails does BillBahi read?

With a Gmail or Outlook connection, only messages matching your search filter (statements, invoices, receipts, bank transaction alerts by default) are fetched. With forwarding, only what you forward. Promotions and personal mail are never requested.

My bank statements are password-protected. Will they work?

Yes. Save the statement passwords in Settings (they are stored encrypted). If one is missing, the statement waits in your email log until you add it, then is read and audited.

Is the audit a tax audit?

No. The audit is a set of automated checks that help you and your CA find gaps and mistakes. It is not an audit under the Companies Act or a tax audit under Section 44AB, and it does not replace your CA's professional judgement.

Can my CA change my numbers?

Only if you give them "Full bookkeeping" access. With "Review & audit" access they can categorise entries, write notes, confirm bill matches and run audits, but not change amounts, dates or delete entries.

What does it cost?

BillBahi is free while in early access. We will give at least 30 days' notice before introducing any charges, and you can export all your data at any time.

Start this financial year with clean books.
