Overview

Accountants spend hours reading supplier invoices and typing every line into Tally. Here, AI reads PDFs and photos into a full structured invoice: supplier, items, HSN-wise GST, charges and totals. The user checks it, maps it to their own Tally ledgers and posts it. Bank statements work the same way, and the tool learns each payee’s ledger.

Before and after

Before
  • Invoices arrive in endless layouts, and every line, GST split and charge was keyed by hand.
  • The same payees were categorised again and again on every bank statement.
  • A wrong ledger or a total that didn’t match caused rework at filing time.
  • Re-uploading a statement could double-post entries.
What I built
  • AI extraction of PDFs and photos into a complete invoice, including e-invoice and e-way bill fields.
  • Batch upload of up to 50 invoices with a per-file result.
  • Ledger mapping using lists pulled from the user’s own Tally company, blocking unmapped posts.
  • A draft → finalised → synced workflow that locks posted invoices.

Skip the retyping

Full invoices read from PDFs and photos, line items included.

A pile in one go

Up to 50 invoices processed together, several at a time.

Learns your categories

Each ledger you assign becomes a rule for next time.

Catches mistakes

Balance checks and a warning when a statement was already uploaded.

Controlled AI cost

A monthly quota per user that parallel uploads can’t bypass.

Works with remote Tally

Several companies per user, and Tally reached through a protected tunnel.

Under the hood

Node.jsExpressReactPostgreSQLPrismaVision LLMsTallyPrime XMLDocker
  • Retries and model fallback when an AI provider fails, and rejection of truncated JSON.
  • Balanced vouchers with a computed round-off so Tally matches the invoice total.
  • Payee names reduced to stable signatures so recurring transactions match.
  • Multi-tenant isolation with every query scoped to the signed-in user.

Outcome

Purchase invoices reach Tally without anyone retyping them.
Repeat bank transactions are coded automatically.
Double-posting is blocked by design.
