What you get

One quiet dashboard for everything a bylaw officer asks for.

Bylaw checklist, per municipality

Every requirement for your town — licence, insurance, fire, septic, signage — as a live checklist. Green when you're covered, red when you're not.

MAT engine

Enter bookings or paste your iCal. We calculate the MAT on every stay and generate the quarterly remittance you hand to the municipality.

Document vault & reminders

Insurance, permit, fire inspection, septic pump. We track expiry dates and remind you before they lapse — not after.
