Fintech app development cost
Fintech is the most expensive consumer category to build in, because correctness is not optional. A neobank or lending MVP with KYC, a ledger and card payments starts around $180,000 and a production platform with fraud controls, reconciliation and SOC 2 runs $400,000 to $750,000.
Cross-platform mobile, 30 screens, 3 user roles, with the compliance posture this vertical carries.
- Timeline
- 5.8 – 7.9 months
- Engineering hours
- 3,025 – 3,825
- Data sensitivity
- 5 of 5
- Default security posture
- Audited
Compliance and security add $73,555 here
That is 16% of this build, measured rather than asserted: we priced the identical app with no named regime and a baseline security posture, and this is the difference. None of it produces a user-visible feature, and none of it can be retrofitted cheaply.
Regimes that apply in this vertical
- SOC 2 Type IINobody by law. In practice it is the entry ticket for selling software to any US mid-market or enterprise buyer, and it is asked for during procurement rather than after.
- $20K – $48K audit
- PCI DSSAnyone handling card data. Hosted fields keep card data off your servers and reduce this to a self-assessment rather than a full audit -- which is a large cost difference.
- $4K – $22K audit
- GLBA Safeguards RuleFinancial institutions, and many fintechs handling consumer financial information.
- $10K – $32K audit
- KYC / AML programmeMoney transmitters, lenders, brokers and most fintechs touching customer funds. It is an operational programme, not only software.
- $15K – $50K audit
- GDPRAnyone offering services to people in the EU or UK, wherever your company is. A US-only product with US-only users is generally outside it.
- $0 – $12K audit
- CCPA / CPRABusinesses over the revenue or data thresholds with California consumers. In practice, most US consumer products at any scale.
- $0 – $8K audit

What makes finance & fintech different
Money must reconcile exactly
A ledger that is approximately right is worthless. Double-entry bookkeeping, idempotent writes, settlement handling and reconciliation reporting are a large, unglamorous chunk of any fintech backend and cannot be deferred to phase two.
KYC, AML and sanctions screening
Identity verification, watchlist screening and suspicious activity reporting are product surfaces as well as vendor bills. They also add an operations queue somebody has to staff.
Fraud is a permanent running cost
Device fingerprinting, velocity rules, a review queue and a dispute workflow are table stakes. Fraud teams tune these forever, so budget for the operational surface, not just the build.
Who uses software in this vertical
Each additional role brings its own screens plus a row in a permission matrix that grows faster than the role count — because every new role is a question about every role that already exists.
