FAQ

Quick answers

Short answers for the questions that usually come up first.

Why split the remaining balance evenly?

Equal milestones are a simple starting point and make the schedule easier to communicate, even if the final contract uses different weights later.

Can I still use this if I only want one milestone after the deposit?

Yes. Set the milestone count to one and the remaining balance becomes one scheduled payment.
