Site logbook: real-time margin
The owner finds out whether a site made or lost money a month after it ends. Hours come in on paper on Fridays, photos stay on phones, materials bought urgently aren't linked to anything, and extra work requested on site is never billed.

Hours logged from memory, scattered photos, unassigned emergency purchases, quotes priced by guesswork.
A very simple mobile app for tradespeople, with all the intelligence on the office side.
Problem
An SME in finishing trades (plumbing, heating, electrical), about twenty tradespeople, several sites running in parallel.
Hours logged from memory, scattered photos, unassigned emergency purchases, quotes priced by guesswork.
Scoping
The obvious move would be to buy a full management software. The real blocker is field data entry: if it takes more than a minute, nobody does it. Approach taken: a very simple mobile app for tradespeople, with all the intelligence on the office side.
The tool
Tradesperson side
- Clock-in and clock-out per site.
- Before and after photos attached automatically.
- Materials used or purchased (photo of the receipt).
- Extra work with description, photo and the client's signature on screen.
- Reporting of unexpected issues or safety problems.
Office side
- Real margin per site compared to the quote.
- Budget overrun alert.
- List of extra work to be billed.
- Complete photo record per site.
- Team workload and scheduling.
Decisions

Allocate teams according to their actual workload.
Management
Track committed cash flow site by site.
What it delivers
The company asked for a tool to clock hours. It gets the margin of each site while there is still time to act.
