PropFix: a field service command layer for modern maintenance teams.

Context

A property manager looking after multiple sites is the hub of every maintenance job — taking the report, finding an available contractor, confirming the work happened, and answering for it if an owner asks later.

What kept breaking

Jobs lived in phone calls and messages, so nothing was searchable. Nobody could say which jobs were open right now without asking around. And "it's done" was a claim, not a record — which made invoice disputes unwinnable in either direction.

The real requirement

A shared state that all three parties read from and write to: the manager who raises the job, the contractor who does it, and the admin who oversees the whole portfolio.

Invite-code onboarding

Contractors are not customers — they should not self-register into someone else's portfolio. Access is granted by a manager-generated invite code, so the contractor directory stays a curated list rather than an open sign-up form.

Proof of work

Before and after records attach to the job itself, not to a chat thread. When an invoice is queried months later, the evidence is already sitting on the record rather than somewhere in a phone's camera roll.

Sync you can see

The dashboard states its own sync status rather than silently assuming it is current. A field worker with poor signal can tell the difference between "nothing to do" and "we have not heard from the server lately" — a distinction most apps quietly collapse.

Shared logic, native shells

Compose Multiplatform with Koin dependency injection and a local SQLDelight cache. Business rules are written once; each platform keeps its own native presentation.
