The problem
A major energy-sector player's Finance & Accounting team ran a highly manual, time-consuming, and error-prone payroll and vendor payment process. They extracted data from internal ERP systems, manually filled bank-provided Excel templates, and uploaded those sheets to the banking portal. Formatting mistakes or wrong account details often rejected the entire batch, delaying salaries and vendor settlements.

- High error rate: manual keying caused formatting errors or incorrect account details; a single fault rejected the whole bulk file.
- Time consumption: the team spent days each month cross-referencing data and fixing sheet formats instead of financial analysis.
- Rejection loops: each failed upload meant find-fix-reupload cycles that delayed salary and vendor payments.
What we built
- Automated data mapping from source files into the bank's required Excel formats for payroll and vendor payments.
- ML-based verification trained on historical successful payments to pre-validate files before generation.
- Error detection for mismatched account numbers, invalid IFSC codes, and vendor-name discrepancies.
- Correction suggestions based on prior payment behaviour so the F&A team could fix issues before upload.
- A lightweight interface: upload raw data, click Process, and receive a bank-ready, sanity-checked file.

The implementation
Phase 1: Analyse historical payment data to train the ML model.
Phase 2: Build mapping logic for payroll and vendor bank formats.
Phase 3: Integrate with the client's workflow and train users, with IT and F&A stakeholders for security and compliance.
The result
By removing manual data entry and adding intelligent pre-checks, the client cut data-entry errors by about 95%, sped processing by roughly 60% (from 3–4 days to 4–6 hours), and reclaimed over 30 hours per month for reconciliation and reporting.
