Domain we build for

Fintech and wallet apps where every rupee has a trail

Custom software for this vertical — scoped to your workflows. Not a packaged product we resell, and not a claim that we run every company in this space.

Financial products get judged on trust before features — a wallet balance that's off by a few rupees, or a lending flow with no clear audit trail when a customer disputes a charge, does more damage than a missing feature ever would. We design wallets, payment experiences, KYC and lending flows, and personal finance dashboards with careful transaction UX, clear admin controls, and the kind of logging you want when something looks off — every debit, credit, and status change tied to a reason and a timestamp, not just a final balance. For lending products specifically, that means EMI schedules that are visible and explainable to the borrower, not just calculated correctly in the backend. We treat auditability as a first-class requirement rather than something bolted on after a compliance review flags it.

What a fintech & digital wallet build usually includes

  • Wallet top-ups, transfers, and payouts
  • Payment gateway and UPI-style flows
  • KYC steps and document checks
  • Lending applications and EMI trackers
  • Spend and balance views users understand
  • Fraud flags and admin audit trails

How we approach a fintech & digital wallet build

  1. 1

    Design the ledger and audit trail first

    Every transaction type — top-up, transfer, payout, refund — gets a defined state machine and reason code before any screen is built, since retrofitting auditability later is far riskier.

  2. 2

    Build KYC and payment flows to fail safely

    Document checks, gateway integrations, and error states are designed so a failed step never leaves money or KYC status in an ambiguous middle state.

  3. 3

    Add fraud flags and reporting for operations

    Admin dashboards for flagged transactions, dispute handling, and reconciliation reports come once the core money-movement flows are stable and tested.

Frequently asked questions

How do you ensure wallet balances stay accurate?

Every balance change is derived from an immutable transaction log rather than a mutable balance field alone, so discrepancies can always be traced back to a specific event.

Can you integrate KYC verification providers?

Yes — we integrate with KYC/document-verification APIs (Aadhaar-based or equivalent) and design the flow so a failed verification has a clear retry path instead of a dead end.

Do you build lending and EMI tracking features?

Yes, including EMI schedules visible to the borrower, automated reminders, and admin tools to track defaults and restructure schedules when needed.

How long does a fintech or wallet app take to build?

A wallet-and-payments MVP typically ships in 10 to 14 weeks given the extra care KYC and audit logging require; adding lending flows extends that to 4 to 6 months.
