48-Hour Bank Exception & Tally Reconciliation Pilot
Client: Multi-entity mid-market enterprise · Scale: ₹48,22,500 across 21 unresolved bank & AR/AP exceptions
21 bank exceptions, ₹48,22,500 cleared in 48 hours, Tally general ledger untouched.
CLIENT PROBLEM
A finance team running on Tally Prime across multiple bank accounts faced a recurring month-end bottleneck: unapplied customer cash (AR), duplicate vendor bill checks (AP),TDS mismatches, and bank statement lines whose UTRs did not cleanly match Tally voucher narrations. Manual spreadsheet reconciliation consumed days of controller and accountant bandwidth while leaving ₹48,22,500 across 21 open exceptions unresolved.
OUR SOLUTION & ARCHITECTURE
Deployed TIEOT (`https://tieot.autonmis.com/`) as an AI-native finance subsystem sitting beside Tally Prime on read-only exports. TIEOT's deterministic accounting engine (Keel) ran exact-decimal reconciliation across the bank feeds, gateway settlements, and Tally vouchers — never using an LLM to calculate or guess a balance.
Within 48 hours of ingesting the exports, Keel isolated and resolved all 21 bank and ledger exceptions totaling ₹48,22,500. Language models were restricted strictly to drafting plain-English controller briefs over Keel's published figures. The Tally general ledger remained completely untouched.

WHY IT MATTERS & SYSTEM MECHANICS
- Trigger
- Daily bank statement export and Tally Prime daybook/voucher sync land in TIEOT.
- Sources
- Tally Prime exports · Bank statement CSV/feeds · Gateway settlement reports
- Human Loop
- Controller reviews matched pairs and exception cases in TIEOT; Tally general ledger remains 100% untouched until approved voucher actions are signed off.
- Narration drift between bank feeds and Tally vouchers.
- Bank UTR references, gateway batch settlements, and Tally Prime voucher narrations rarely shared a clean key, leaving dozens of high-value entries unapplied.
- Spreadsheets introduced rounding and formula risk.
- Manual VLOOKUP sheets across bank CSVs and Tally exports took days and risked silent formula errors on TDS deductions and partial settlements.
