Built for how HVAC contractors work
Save your services once, reuse them forever
Keep your usual services and materials in the item catalog with your prices, then add them to any estimate in a tap instead of retyping them.
Clients approve and sign online
Clients open the estimate from a link, approve it and sign on their phone. The approved estimate becomes an invoice in one click.
Get paid online
On Pro and Business, clients pay invoices by card through your own Stripe account. The money goes straight to you — MCR System takes no cut.
Photos on the estimate
Attach job photos to estimates and invoices (up to 4 on Pro, 10 on Business) so the client sees exactly what you'll do — or what you did.
