PortFix Escrow Marketplace
State Machine Process

Transparent Lifecycle from Request to Payout

PortFix eliminates contractor dishonesty and payment disputes using automated escrow milestones and grab-style change order approvals.

1

Post Issue & Match Nearby Technicians

Select a category (Aircon, Plumbing, Wiring), describe the fault, and set your location. The PortFix matching engine routes your request to eligible TVET-certified technicians within 15km.

2

Quote Review & Isolated Escrow Lock

Technicians send fixed-price quotes with itemized labor and parts. When you accept, payment is deposited into the PortFix Escrow vault. The technician knows payment is guaranteed, and you know funds won't leave until you're satisfied.

3

GPS Arrival & Grab-Style Change Orders

Technicians check in at your location with geofence verification. If unexpected damaged parts are discovered mid-job, the technician submits a digital Change Order on-site. You can approve or decline the add-on right from your phone.

4

24-Hour Quality Hold Period

After work is finished, an automated 24-hour countdown begins. Test your repairs at home. If there's an issue, raise a 1-click dispute before funds are ever paid out. If no issue is raised, escrow is auto-credited to the provider's wallet.
