Tuesday, eight in the morning.
A homeowner posts a job: leaking shower tray, two photos, postcode, "within the week".
The platform notifies the plumbers and bathroom fitters whose profiles are live and whose distance setting covers that postcode.
Four trades open the post on their phones; three spend a lead credit to express interest and the fourth decides it is too far.
The homeowner sees three profiles, each with a badge listing which checklist items were recorded and when, their review history from confirmed jobs, and a short message from each.
She shortlists two.
