About the client
Minato Transport Service Co., Ltd. is a haulage operator whose main business is carrying construction spoil and collecting and transporting industrial waste. It runs dump trucks, heavy machinery and rented vehicles across many construction sites and disposal grounds, where each day’s haulage decides whether a project pays.
The design problems to solve
The work got done, but the data was fragmented — before the launch, Minato Transport Service faced four structural problems.
Paper reports written in the field were retyped into Excel at the office.Digitise the reports and , the double work of retyping and tallying disappears.
Utilisation, fuel and depreciation sat scattered in a spreadsheet per vehicle.Manage it in one place and , utilisation and depreciation status are known at once.
Project cost stayed invisible until the monthly close, so loss-making projects were found late.Aggregate daily and , profitability can be judged while the job runs.
Revenue and cost were managed apart, so gross profit could only be known after the fact.Handle it on one platform and , management decisions become real time.
The architecture we built together
Starting from the mobile report in the field, the business API, the costing engine and the dashboards were built on a single data model. The domain was split into four areas, with Amela alongside from design through implementation.
Solution: Log haulage in a few taps after picking project and vehicle, with photo attachment and offline drafts.
Solution: A business API managing projects, vehicles, materials, waste and members in one schema.
Solution: An engine allocating reports, expenses, labour and depreciation into project cost automatically.
Solution: Revenue, cost, gross profit and utilisation aggregated and shown in real time.

MySQLThe value the platform creates
Putting the once-separated field and back office on the same data produced four things the company can now do.
Reports entered on mobile and sent on the spot.
Utilisation, fuel and depreciation per vehicle on one screen.
Judge cost and gross profit per project without waiting for the close.
Revenue, cost and utilisation come together for decisions.
