The challenge

A financial institution running on paper

The society managed members, loans, fixed and recurring deposits, and its books through manual ledgers, spreadsheets, and in-person paperwork. Every loan meant back-and-forth approvals by hand, records lived in different places, reconciliation was slow, and members had to visit the office for the simplest requests. As membership grew, the manual model couldn't keep up — and it made compliance and clean audits genuinely hard.

What we built

A single system for the whole operation

Loan & deposit management

End-to-end loans plus fixed-deposit (FD) and recurring-deposit (RD) management, with interest handling and structured, rule-based processing.

Member self-service — web & Android app

Members view balances and statements, track deposits, and apply for loans from a web portal or a native Android app — without a trip to the office.

Aadhaar KYC + maker-checker

Compliant onboarding with Aadhaar-based KYC and a maker-checker approval flow, so no sensitive change goes live on one person's say-so.

Razorpay payments

Integrated online payments, so contributions and repayments happen digitally and reconcile against member accounts.

Double-entry accounting

Proper double-entry books with full audit trails — every transaction traceable, balances always reconciled.

Admin back-office

A control centre for staff to manage members, approvals, and reporting — the operational heart of the platform.

The outcome

What changed for the society

  • Off paper, onto one system. Member records, loans, deposits, and accounts now live in a single source of truth instead of scattered ledgers and spreadsheets.
  • Faster, structured loan processing. A digital approval flow replaced manual back-and-forth, so applications move through clear, consistent steps.
  • Members serve themselves. Balances, statements, and loan applications are available online — cutting office visits and manual queries.
  • Audit-ready books. Double-entry accounting with audit trails and maker-checker controls made records accurate, centralized, and far easier to reconcile and review.
  • Ready to grow. A modern, cloud-hosted stack that scales with membership instead of buckling under it.
Under the hood

Technology
