Fintech Software Development in York

Building financial products for York fintechs, starting with the question that determines everything else: does the activity fall inside the regulatory perimeter. Holding customer money, arranging credit and executing payments are regulated activities, and the answer decides your architecture, your timeline and whether you can launch at all.

Why this comes up

The problem

The product is built, the launch date is set, and nobody has established whether the activity needs authorisation or someone else's permissions.

What you get

What we deliver

  • The perimeter question settled before the architecture assumes an answer
  • Customer funds segregated and reconciled if the model involves holding money
  • Ledgering built properly, since a balance derived from events must be provable
  • Onboarding checks designed into the flow rather than bolted alongside it
  • Reporting the regulator expects produced from the system, not from exports
  • A separation between your money and customers' money that survives audit

Fintech Software Development in York — common questions

How do we know if we need authorisation?
Take advice early, because the perimeter is drawn around specific activities rather than around business models. Firms frequently assume a partner's permissions cover them, or that a technology framing avoids the question, and discover otherwise close to launch.
What does safeguarding customer funds require?
Keeping them separate from the firm's own money, in a way that protects customers if the firm fails, with reconciliation on a defined frequency. It is an operational discipline with a system requirement behind it, not a bank account naming convention.
Can we use an appointed representative route?
It is a legitimate way to reach market faster under a principal's permissions, but the principal carries responsibility for you and will impose controls accordingly. Treat it as a commercial relationship with real constraints rather than a shortcut around them.
Why build a ledger rather than store balances?
Because a stored balance cannot be explained. When a customer disputes a figure you need to show the sequence of entries that produced it, and reconstructing that from application logs after the fact is the situation every finance team wants to avoid.
Do you work with businesses across North Yorkshire?
Yes. We are based in Leicester, United Kingdom and work with clients throughout Yorkshire & the Humber, including York and the surrounding North Yorkshire area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
What kind of York businesses do you usually work with?
Visitor-facing booking and ticketing systems that handle extreme seasonality on a small operator's budget. Beyond that we work across Tourism & Heritage, Rail Engineering, Bioscience, Retail and Higher Education.
Do you cover the areas around York?
Yes — we work throughout Yorkshire & the Humber, including Leeds, Newcastle, Sheffield. York is an urban area of roughly 210,000+, and we take on work across the wider North Yorkshire region rather than the city boundary alone.
