We had almost the same situation last year. At first we tried to “optimize” Excel files and chats, but it only worked for small jobs. Once projects overlapped, everything broke down. What really helped was moving procurement into a structured ERP approach made specifically for construction. With ERP system for construction business, you get clear workflows for requests, approvals, supplier management, and cost control in one place. It reduces human error, makes spending transparent, and lets managers see the real picture without chasing updates. It’s not magic, but compared to manual methods, the difference is huge and actually noticeable on site.
