Fintech Website Development: What Your Site Needs
A fintech website has to win trust in seconds and pass a compliance review. Our fintech website development services cover the parts a regular business website does not:
- Trust and disclosure pages: licensing, regulatory and risk disclosures, privacy and security pages written with your compliance team.
- Calculators and tools: loan, savings, fee and currency calculators that turn visitors into applicants.
- Secure lead and onboarding forms: encrypted forms that hand applicants over to your KYC and onboarding flow.
- Speed and security: fast pages, HTTPS everywhere, security headers and protection against bots and form spam.
- Accessibility: pages built to WCAG guidelines so every customer can use them.
- SEO and analytics: pages structured for search, with consent-aware analytics to measure sign-ups.
When your website needs a logged-in area, we extend it into a customer portal or platform on the same back end.
Fintech Website Development Cost and Timeline
Our rates start from $35 per hour and projects start from $1,000. A fintech marketing website costs far less than a portal with banking and KYC integrations, so we give you a written estimate for your scope before work starts.
A fintech website or MVP usually takes around 2 to 4 months. A starter MVP costs $3,000, or $1,500 when you claim our free clickable design of 5–6 key screens. For app budgets, see how much a banking app costs or try the cost calculator.
