Defects

Punch list, handled

Homeowners report issues with photos. Contractors submit fixes. You sign off — all in one threaded view.

Homeowner Portal

Your clients stay in the loop, automatically.

Homeowners get their own view: project timeline, stage progress, invoices to pay, and a direct line to flag defects — without the WhatsApp back-and-forth.

How it works

Built for every person on the project.

One place for every project

Create projects, break them into stages and tasks, assign contractors, and track everything from a single dashboard.

Quotes that write themselves

Your stages and tasks feed directly into a branded PDF quotation. Add a payment schedule and send with no reformatting needed.

Milestone billing, simplified

Issue invoices at each payment milestone and track received vs outstanding at a glance. No more chasing spreadsheets.

Contractors in their lane

Invite contractor companies and they see only what's assigned to them. Scope, status, payments, all separated cleanly.

Defects handled in-app

The homeowner flags issues, the contractor fixes them, you sign off. The whole loop happens in all one place, no need for WhatsApp.
