Honest advice and solid execution

Jess Harding / Founder & CEO | Sep 10, 2026

GLS Labs did an excellent job for us. They were upfront about what was realistic within our budget, which helped us prioritise the right features. Their project manager kept things organised and was quick to flag anything that might affect the timeline.

Since launch, everything has been stable and our team has adapted to it quickly. I would recommend GLS Labs to anyone looking for a dependable Software Development partner.

Project summary

GLS Labs was brought in to develop a scheduling and dispatch tool for our field team. They also took care of integrations with a couple of third-party tools we already used. We worked together for around 3 months.

Easy to work with and very transparent on timelines and cost

Sneha Mehta / Chief Digital Officer | Jun 13, 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. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time.

We launched on schedule and have not had any major issues since. If you need a team that communicates well and delivers, they are a good choice.

Reliable AI & Machine Learning Partner That Delivered What They Promised

Nicole Hayes / IT Director | Mar 23, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. Even with the time zone difference, responses usually came the same day and we never felt left in the dark. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time.

The AI & Machine Learning work has already made a noticeable difference — tasks that used to take hours now take minutes.

I would recommend GLS Labs to anyone looking for a dependable AI & Machine Learning partner.

Project summary

We hired GLS Labs to automate document data extraction that our team was doing by hand. Their team handled planning, development and QA, with our product owner signing off each milestone. Overall it was a 8-month engagement.

Good results, communication improved as the project went on

Charlotte Hughes / Director | Mar 04, 2026

Overall the project was a success, though it was not without some challenges. They were upfront about what was realistic within our budget, which helped us prioritise the right features. Their project manager kept things organised and was quick to flag anything that might affect the timeline. 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.

The result looks great and performs well, and our internal team found it easy to take over. Documentation at handover was a bit thin and we had to ask for more detail.

If you need a team that communicates well and delivers, they are a good choice.
