How it works

Three steps from call to launch

  1. 1

    Free call and fixed quote

    Book a free call during US hours (Mon–Fri, 9 AM – 6 PM ET). Kwebby maps your money flows, partners and security needs, then sends a fixed quote with milestones.

  2. 2

    Build in sandbox milestones

    You pay 10% to start. Kwebby builds against sandbox accounts from Stripe, Plaid and your KYC provider, and you test each milestone in the client portal before approval. The 40% payment is due at the midway milestone.

What a fintech app development company builds

A fintech app development company builds software that moves, stores or tracks money. Kwebby builds payment apps, digital wallets, lending platforms, budgeting tools, investing dashboards and back-office tools for finance teams.

Fintech apps carry more risk than typical apps. A bug can send money to the wrong place, and a weak login can expose financial data. Kwebby designs each money flow, permission and audit trail before any code is written.

Most fintech founders start with one core flow, such as sending payments or linking bank accounts, and add products after launch. Kwebby scopes that first flow into a fixed quote.

Security and compliance foundations

Kwebby builds every fintech app on the security basics that auditors and partners expect to see. These controls protect users and prepare your app for partner reviews.

Kwebby is not an auditor and does not certify compliance. Your compliance counsel and auditors confirm your obligations for PCI DSS, SOC 2, KYC and AML rules, and Kwebby builds the app to match their requirements.

  • Multi-factor authentication and device checks
  • Encryption in transit with TLS and at rest with managed keys
  • Card data handled by PCI DSS-compliant processors, never stored on your servers
  • Role-based access for staff and admins
  • Tamper-evident audit logs for money movements and account changes
  • Rate limits, fraud rules and alerts for unusual activity

Payments, banking and identity integrations

Most fintech apps run on established partners instead of building financial infrastructure from scratch. Kwebby connects your app to these providers through their official APIs and tests every flow in sandbox mode first.

Many fintech products work through a licensed partner bank or a banking-as-a-service provider. Kwebby builds the app to meet each partner's technical and review requirements.

  • Stripe for card payments, subscriptions, payouts and connected accounts
  • Plaid for bank account linking, balances and transaction data
  • KYC providers such as Persona or Alloy for identity checks
  • Banking-as-a-service partners for accounts and cards
  • Accounting tools such as QuickBooks for reconciliation

Start with a fintech MVP

A fintech MVP tests whether users trust your product with their money. It includes secure login, one core money flow, an admin panel and the audit trail your partners need.

Kwebby recommends launching in one market with one product line first. Each new product, such as cards, credit or investing, then adds to a proven foundation.

The MVP uses production-grade code, encrypted data and real sandbox-to-production integrations. Version two builds on it instead of replacing it.

What fintech app development costs

Kwebby fintech projects start at $7,999 for an MVP with secure login, one core money flow, an admin panel and audit logs. The price grows with each integration, user type and compliance requirement.

A budgeting app with Plaid costs less than a lending platform with underwriting rules, document checks and repayment schedules. Kwebby lists every feature and integration in your fixed quote.

Payments follow the 10/40/50 split: 10% to start, 40% at the midway milestone and 50% on delivery. Providers such as Stripe, Plaid and KYC services bill their fees to your accounts directly.

Frequently asked questions

How much does it cost to build a fintech app?

Kwebby fintech apps start at $7,999 for an MVP with secure login, one core money flow, an admin panel and audit logs. More integrations, user types and compliance features add to the price. You get a fixed quote after a free call.

How long does fintech app development take?

Most fintech MVPs take 10–20 weeks. Partner onboarding with banks, KYC providers and payment processors can add time, so Kwebby plans those steps from the start.

Does Kwebby handle PCI DSS compliance?

Kwebby builds on PCI DSS-compliant payment processors such as Stripe, so raw card numbers never touch your servers. This keeps your PCI scope small. Your compliance advisor confirms your final obligations.

Do I need a bank partner or a license?

It depends on your product and where you operate. Many fintech apps work through a licensed partner bank or a banking-as-a-service provider. Your legal counsel confirms licensing needs, and Kwebby builds the app to match your partner's requirements.

Which integrations do you support?

Kwebby integrates Stripe, Plaid, KYC providers such as Persona and Alloy, banking-as-a-service platforms and accounting tools such as QuickBooks. Kwebby can add any provider with a documented API.

Will you sign an NDA before we share details?

Yes. The first call can stay high level, and Kwebby can sign your NDA before you share confidential product or partner details.

Do I own the code?

Yes. You own 100% of the code, infrastructure and data. Kwebby deploys to cloud accounts in your name and hands over the repository and documentation at delivery.
