Great team to work with — professional, responsive and reliable

Laura Koch / Director | Oct 10, 2026

We were happy with the final result. The developers were knowledgeable and made a few suggestions that ended up saving us time and money. Their project manager kept things organised and was quick to flag anything that might affect the timeline.

The result looks great and performs well, and our internal team found it easy to take over. A couple of milestones slipped by a week or so, mostly around testing. If you need a team that communicates well and delivers, they are a good choice.

Project summary

Our company worked with bluumi to rebuild an internal order management system that had outgrown its original design. They worked alongside our in-house team, which mostly handled business requirements and testing. Overall it was a 9-month engagement.

Solid delivery, though timelines needed some pushing

Neha Bose / Marketing Director | Mar 10, 2026

Overall the project was a success, though it was not without some challenges. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. 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.
