Questions
What builders ask us.
Can my crew use it on site?
Yes. Everything works on a phone, and each person gets their own login with only what they need.
Can we bill by project stage?
Yes. Set up stages for each project and send an invoice as each one is completed.
We already use estimating software. Does that matter?
No. QuantumStack can run the client side, the follow-up and the billing, and we can connect it to the tools you keep.
