Cost drivers specific to fintech
| Driver | Why it adds cost | Typical effect |
|---|---|---|
| Identity and anti-fraud checks | Customers must be verified before money moves | $4,000 to $10,000 plus per-check fees |
| A double-entry ledger | Every cent must balance and every change must be traceable | +15 to 25% on the back end |
| Bank and card connections | Each provider has its own rules, sandbox, and approval | $2,500 to $6,000 per provider |
| Security audits | Investors, banks, and partners ask for proof of controls | $20,000 to $48,000 for readiness |
| Reconciliation and reporting | Finance teams need daily matching and exportable reports | $5,000 to $12,000 |
Why fintech software costs more
In most software, a small bug is an inconvenience. In financial software, a small bug can move money to the wrong place, double-charge a customer, or break a regulatory rule. That changes how the software is designed, built, and tested, and it is the main reason fintech projects cost more than the same features elsewhere.
Fintech also depends on partners. Banks, card networks, payment processors, and identity providers each have their own interfaces, test environments, and approval steps. A large share of the work is making those partners behave reliably together.
The five cost drivers that are specific to fintech
The first is identity. Before customers can move money, they must be verified through know your customer (KYC) checks, which confirm who someone is, and anti-money-laundering (AML) screening, which checks them against sanctions and risk lists. These are bought from specialist providers, who charge per check, and wired into onboarding.
The second is the ledger. Serious financial products record every movement of money twice, as a debit and a credit, so the books always balance and every change can be traced. Building that properly adds 15 to 25 percent to the back end, and it is not something to skip.
The third is connections to banks and cards. Open banking services read account data with the customer's permission. Payment processors such as Stripe handle cards and payouts. Each provider has its own sandbox and approval process.
The fourth is security evidence. Partners and investors often ask for a SOC 2 report, an independent audit of security controls, and card handling must follow PCI DSS, the card industry's security standard. We design to keep card data out of your systems wherever possible, which shrinks the audit.
The fifth is reconciliation. Finance teams need to match every transaction against bank statements daily, with reports they can export.
Key points
- Identity and anti-money-laundering checks
- A ledger where every cent balances
- Bank, card, and payout providers
- Evidence of security controls
- Daily reconciliation and reporting
What is included in the price
Every fintech quote from us includes a money flow map showing where funds and data move, which provider handles each step, and where risk sits. The build includes a ledger, audit trails, role-based access, and automated tests for every calculation. Before launch we run security testing, check reconciliation against real test transactions, and prepare documentation for your compliance and audit teams.
A typical timeline
A payments web app takes six to ten weeks. Onboarding and lending portals take eight to twelve weeks, mainly because identity providers and approval rules need careful testing. Consumer money apps take ten to sixteen weeks, often released first to a small group before a public launch. Partner approvals can add time outside anyone's control, so we start them in week one.
A worked example
Picture a small business lender that takes applications by email and assesses them in spreadsheets. Decisions take a week, and good applicants go elsewhere.
The project is an onboarding portal. Applicants verify their identity, connect their business bank account with permission, and upload documents. The portal pulls bank data, calculates key ratios, and flags applications for an analyst to approve. Every decision is logged. It falls in the $44,000 to $56,000 range including identity and bank connections, and launches in about ten weeks. Decisions move from a week to under a day, every file is complete, and analysts spend their time on judgment rather than data entry.
How to keep fintech costs under control
Buy the regulated parts. Identity checks, card processing, and account data are better bought from licensed providers than built. Keep card data out of your systems so your security audit scope stays small. Launch to a limited group first, with lower transaction limits, and widen access as monitoring proves the system. A careful first month costs far less than a public mistake.
How to compare fintech quotes
Ask each supplier to explain how money will be recorded. If the answer is a balance column that goes up and down, rather than a ledger of individual entries, the system will be hard to audit and harder to fix when something goes wrong.
Ask which identity, banking, and payment providers they plan to use, and whether those providers are licensed in the markets you serve. Ask how card data will be kept out of your systems, and how large your security audit scope will be as a result. Ask how they test calculations, interest, fees, and rounding, and whether those tests run automatically on every change.
Finally, ask who will prepare the documentation your auditors and partners will request. Writing it after launch, from memory, costs far more than writing it alongside the build.
Key points
- A real ledger, not a balance column
- Licensed providers for identity, banking, and payments
- Card data kept out of your systems
- Automated tests for every calculation
- Audit documentation written during the build
