We were very happy with how this project went. They were upfront about what was realistic within our budget, which helped us prioritise the right features. We dealt with the same core team throughout, so we did not have to keep re-explaining things.

Feedback from our customers has been very positive so far. Happy to recommend them.

Delivered on time and stayed involved after launch

Amit Menon / General Manager | Sep 13, 2026

Flexible Sites did an excellent job for us. When we changed our minds on a couple of features halfway through, they handled it without fuss and were clear about the impact on cost and timeline. They were upfront about what was realistic within our budget, which helped us prioritise the right features. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later.

It has made a real difference to how our team works day to day.

I would recommend Flexible Sites to anyone looking for a dependable Mobile App Development partner.

Project summary

We partnered with Flexible Sites to develop a field-staff app with offline mode that syncs back to our main system. The project was split into milestones, with a working build shared at the end of each one. Overall it was a 9-month engagement.

Quality work, a little slower than we planned

Julie Thompson / IT Manager | Jun 28, 2026

The final product works well for us, although the process could have been smoother. We dealt with the same core team throughout, so we did not have to keep re-explaining things. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building. Their project manager kept things organised and was quick to flag anything that might affect the timeline.

It has made a real difference to how our team works day to day. Documentation at handover was a bit thin and we had to ask for more detail.

I would recommend Flexible Sites to anyone looking for a dependable Web Development partner.

Project summary

We partnered with Flexible Sites to rebuild a slow, outdated web app and move it to a new framework. Their team handled planning, development and QA, with our product owner signing off each milestone. We worked together for around 8 months.

Sara Al Nuaimi / Head of Product | May 31, 2026

We were very happy with how this project went. We dealt with the same core team throughout, so we did not have to keep re-explaining things. Even with the time zone difference, responses usually came the same day and we never felt left in the dark.
