Apps, systems, and portals
built to fit your business exactly.
When nothing off the shelf fits, we build it. Client-facing tools that look exceptional, internal tools that people actually use, and systems that bring everything together.
DotPerformance designs and builds bespoke apps, internal systems, and client portals for organisations that have outgrown off-the-shelf software or need something built around their specific workflows. We handle everything in-house, from scoping and UX design through to build, testing, integration, and ongoing development. Every solution is built by a senior team with over 20 years of development experience.

Every system we build is designed before it is built. We map the user journey, prototype the interface, and test it before a line of code is written so the build phase has a clear foundation.
- User journey mapping
- Wireframing and prototyping
- Interface design in Figma
- Usability testing
- Design system documentation
QA and Testing
The same QA standard we apply to every build. Every function tested, every edge case considered, and nothing released to a live environment until it passes. No shortcuts.
- Functional testing
- Cross-device and browser testing
- Performance and load testing
- Security testing
- Bug tracking and resolution
Hosting and Infrastructure
Every application we build is hosted on AWS, giving you enterprise-grade reliability, automatic backups, and the infrastructure to scale without compromise. Managed by us so you do not have to think about it.
- AWS cloud hosting

INSIGHTDevelopment FAQ.
How do I know if I need a bespoke app or system?
If you are running your business on workarounds, spreadsheets, or software that was never quite right for what you do, you probably need something built for you. The same applies if you have multiple systems that do not talk to each other or a client-facing process that feels manual and inconsistent. A 30 minute conversation is usually enough to know whether a bespoke build is the right answer.
How long does a development project take?
It depends entirely on the scope. A focused web app or client portal typically takes between 4 and 16 weeks from scoping to launch. More complex systems with multiple integrations take longer. We agree a clear timeline before work begins and manage it transparently throughout.
How much does bespoke development cost?
Every project is scoped individually based on what you need. Development projects typically start from five figures. The scope and timeline are agreed before any work begins so there are no surprises. The best starting point is a conversation with Andy.
Do you build for iOS and Android?
Yes. We build native and cross-platform mobile apps for both iOS and Android. We also handle app store submission and ongoing development and support after launch.
Can you integrate with our existing systems?
Yes. We connect with any API, any platform, and any level of complexity. CRMs, payment gateways, booking systems, data feeds, and third party platforms. We have yet to find an integration we could not handle.
How do you handle security and data protection?
Security is built in from the start, not added at the end. Every application we build includes secure authentication, data encryption, GDPR compliance, and vulnerability testing as standard. We apply the same security standards our government and banking clients require across every project.
What happens after the app or system goes live?
We stay involved. Most clients move onto a retained development relationship covering ongoing improvements, new features, performance monitoring, and support. The launch is the starting point, not the end of the relationship.
Do you host and manage the infrastructure as well?
Yes. Every application we build is hosted on AWS with automatic backups, performance monitoring, and disaster recovery included. We manage the infrastructure so you do not have to think about it.
Can you take over a system someone else built?
It depends on what we find when we look under the hood. We assess every inherited codebase honestly before committing to anything. If it is salvageable we will tell you. If it is not, we will tell you that too.
