Our Existing Work

Apps for all occasions

Our SAP app development service can help you bridge a gap in functionality, or extend an existing application. We use the SAP Apphaus Methodology, meaning human-centred design and design thinking are at the very centre of this service. We don't just build and deploy - we explore, discover, design, run and scale, all delivered by our accredited BTP experts.

Here's a flavour of the custom apps we have produced before, but we create any custom app your business need.

The way we work

Workshops

Bring together your team and our experts in a creative, collaborative environment. Our custom app development begins with exploration workshops, hosted at our AppHaus space or virtually. We focus on understanding your business challenges and processes. This helps us create a holistic user-centric solution that drives your business forward- rather than just dealing with the symptoms.

Technologies

We harness the full capabilities of SAP Business Technology Platform to deliver your solution, delivering the latest tech whilst keeping your core clean.

Additionally, we can integrate AI technologies to accelerate smarter, data-driven insights and enabling your business to stay ahead in a rapidly evolving digital landscape.

Development

Our development process begins with prototyping and design, ensuring we create solutions that are not only functional but also visually engaging. Using SAP Build and UI5, we strike the perfect balance between rich user interfaces and rapid deployment. SAP Build accelerates the development of applications with low-code tools, ideal for delivering fast solutions, while UI5 provides the flexibility to create complex, highly customised user experiences.

Testing

We provide comprehensive support during user acceptance testing (UAT), guiding your team through every step of the process. We offer hands-on assistance, ensuring your team feels fully supported while validating the app’s performance and functionality. Our experts are available to address any queries, make adjustments, and ensure the solution meets your expectations. Our proactive approach ensures minimise risk and a smooth transition from testing to go-live, so your team feels confident and ready to leverage the new solution effectively.
