Client Stories
“We've been using CoExtend on both pricing and shop drawing work for a few months now. Honestly, they've taken a real load off our team during the busy tender periods. Takeoffs come back tidy with clear assumptions, and the shop drawings only needed minor tweaks before going down to the workshop.”
“Tried a couple of outsourcing options before settling here. What I like is that they actually ask questions when something isn't clear on the tender drawings rather than guessing. Estimates come back with the workings shown so I can sanity-check the rates myself.”
“Shop drawings used to be my bottleneck. Sent over an SFS framing job last month with a tight turnaround and they had drafts back the next morning. Couple of revisions and we were done. Communication throughout was easy — no chasing.”
“Being on the other side of the world from most outsourced teams I was a bit cautious at first. Turned out the time zones actually worked in our favour — sent drawings at the end of our day and the estimate was sitting in my inbox first thing the next morning. Solid work, fair pricing.”
“Working with CoExtend was a game-changer. They built our MVP in record time using Next.js and the performance is incredible.”
“Their React Native expertise helped us launch on both iOS and Android simultaneously without compromising on native feel.”
