Honest advice and solid execution

Lukas Richter / IT Manager | Aug 03, 2026

I would rate this engagement highly on almost every front. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building. 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.

The result looks great and performs well, and our internal team found it easy to take over. Happy to recommend them.

Project summary

Yellow Sapphire Technologies was brought in to build a customer portal where clients can log in, track orders and download invoices. They also took care of integrations with a couple of third-party tools we already used. Overall it was a 8-month engagement.

Easy to work with and very transparent on timelines and cost

Vikram Reddy / Director of IT | Apr 27, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. Communication was consistent.

Even with the time zone difference, responses usually came the same day and we never felt left in the dark.
