Money you can already see
Every visit you book already carries its price. Finances adds them up for the month, so you see your revenue without typing a single number twice.
One Paid toggle, no homework
Mark a visit as paid with one toggle. There are no statuses to manage and nothing to reconcile at the end of the month.
What counts as a cost
Add the costs of your materials to a service once. Every visit of that service then counts them, and your margin shows what is really left.
Reading your margin
Revenue minus costs is your margin for the month. Switch the month to compare it with the one before.
