Banking software development
QASOFT designs, builds and tests software for banks and fintechs, shaped around your products, channels and internal controls, so each release reaches customers on schedule and under control.
- Security reviewed at design
- Independent testing & UAT
- Delivering since 2019
What does banking software development cover?
It means building software around the products, channels and controls of a specific bank or fintech. A QASOFT engagement covers discovery, requirements analysis, solution design with security review, UX/UI, development, independent testing and UAT, then go-live and production support.
Packaged products make you adapt your processes to the software. Custom-built systems work the other way: your products, approval flows and customer journeys are the specification.
- Your digital channels can’t keep up with new products
- Releases slip because testing starts too late
- Customers expect digital account opening and mobile banking
- You need delivery capacity without losing control of the code
Build in-house vs. partner with QASOFT
The first question most banks ask. Both options side by side, including where a partner falls short:
Partner with QASOFT
A delivery team that works inside your processes
- Advantage: Start with a working team instead of hiring one first
- Advantage: Independent testing and UAT included, not bolted on at the end
- Advantage: Experience with digital banking, eKYC onboarding and payments
- Advantage: Scale the team up or down as your roadmap changes
- Advantage: Source code and documentation handed over to you
- Limitation: Your team still owns decisions, approvals and vendor oversight
- Limitation: Onboarding takes time: access, security reviews, knowledge transfer
Build in-house
Hire and grow your own engineering team
- Advantage: Direct control over people and priorities
- Advantage: Knowledge stays inside the institution
- Advantage: Easier to align with internal policies
- Limitation: Hiring takes time before delivery can start
- Limitation: Niche skills like test automation are hard to staff
- Limitation: Fixed headcount cost, even between projects
- Limitation: Testing competes with feature work for the same people
What you get from working with QASOFT
Four things a banking software partner should give you, and that we commit to.
Control over delivery
Scope and acceptance criteria agreed in writing, working software every two weeks, and a clear view of what comes next. No black box between sign-off and go-live.
Security built in from design
Security is reviewed at design time, not patched in before release. Access to your environments and data is agreed with your team up front.
Built for the people who use it
Web, mobile and back-office tools designed around how your retail customers, business clients and operations staff actually work.
Easier to maintain and extend
You own the source code and documentation, so your team or any vendor can extend the system as products and regulations change.

Process
Scope and acceptance criteria agreed in writing before build; working software every two weeks.

Security
Reviewed at design, applied in build, checked in testing.

Frequently asked questions
How does a project with QASOFT run?
Discovery of your systems and constraints → solution design with security review, with scope and acceptance criteria agreed in writing → design, development and testing, with working software every two weeks → SIT and UAT with your team → go-live, handover and production support.
How long does a project take?
It depends on scope, integrations and your internal approval cycles. We agree milestones in writing after discovery and solution design, and you see progress every two weeks rather than at the end.
Can you work with our in-house team and other vendors?
Yes. We can work as a dedicated team inside your sprints, deliver a fixed-scope project, or test software that other teams build. Integrations with your existing systems are planned during solution design.
How do you handle security and data protection?
Security is reviewed at design, access to your environments and data is agreed with you up front, and security-relevant flows are covered in testing. We work within your institution’s policies and vendor requirements.
Can you test software built by another vendor?
Yes. Independent testing is a standalone service: structured test scenarios, regression testing and UAT support across channels, whoever built the system.
Do you support systems after go-live?
Yes. Production support covers incident handling, fixes and small changes after go-live. It is a separate agreement, so you choose the scope, hours and response times.
Who owns the source code?
You do. Source code, technical documentation and operating guides are handed over at acceptance, so your team or any vendor can maintain and extend the system.
