Occasion ran estimation on Excel and quoting on Zoho, two teams on two tools with no link between them, so every scope change had to be re-keyed by hand and reconciled under time pressure, and the quote drifted out of sync with the BOQ behind it. Procurement had no chain at all: purchase requests came in over WhatsApp with no form and no approval trail, purchase orders were raised separately in Zoho, and deliveries were confirmed back on WhatsApp with no link to the PO and no check on quantity, so no one could say whether a request had been ordered, whether it had arrived, or whether it was on site. With scope, procurement, and site progress sitting on different platforms, a delay stayed invisible upstream until it hit site, by which point it had already pushed every trade that followed and the mitigation window had closed. Site reporting depended on someone remembering to message, so clients had no reliable view of their own project.
