How Tiong grows Kosin Contractor without hiring a full team
Published
Running Kosin Contractor on my own used to mean doing every job myself. With OPC operations from Jabbibi, I now bring in reliable contractors for the heavy work, like hauling soil and laying decking, under clear outcome-based freelance agreements. The quality stays consistent, and I don't carry the cost of a payroll. The biggest change has been in how I win work. At the first meeting, I take photos of a client's empty balcony and use AI to show them what it could become, there and then. When clients can see the finished space, they decide much faster. I'd strongly recommend Jabbibi to any tradesperson who wants to take on more projects without hiring a full team.
