Not every lira in the till is profit. See appointment and product income side by side with expenses like rent and supplies, and know what's really left at the end of the day.

Changes you'll notice from the very first week, the kind that genuinely lighten your day.
See your appointment income in the list, and add other income like product sales with a description and amount.
Rent, supplies, bills… Record your expenses with a description and amount so nothing slips through.
As the day closes, total income, expenses and what's left are in front of you at a glance.
Only the business owner sees the finance screen; revenue figures aren't open to your team.
