Set the currency and a personal reserve percentage, then record each product or service honestly. General expenses stay separate so the monthly result is easier to understand.
It keeps product costs, labour, overhead, waste or refund allowance and target margin visible without mixing them into general business expenses. The tax reserve is a user-chosen planning buffer, not tax advice.
Not for sale yet. I built these planners hoping they might help fund future ideas. I take them as seriously as my software, and I won't put this one up for sale until I'm 100% happy with the workbook, the checks and the instructions. I'm still testing it.
The tax reserve is a planning buffer, not a calculation of legal tax liability.
