Accountant & finance partner for small and medium-sized businesses
I keep the books, close the month and explain the numbers for small and medium-sized businesses, from online shops and wholesalers to hair and nail salons, studios, agencies and AI service providers, so you always know how much money you will have, and where it is stuck.
| Wk 9 | Wk 10 | Wk 11 | Wk 12 | Wk 13 | |
|---|---|---|---|---|---|
| Cash in | 4,700 | 8,700 | 9,900 | 9,100 | 6,400 |
| Cash out | 4,680 | 8,700 | 2,980 | 20,950 | 5,090 |
| Closing cash | 19,370 | 19,370 | 26,290 | 14,440 | 15,750 |
| Your buffer | 15,000 | 15,000 | 15,000 | 15,000 | 15,000 |
Week 12: a 12,500 stock order drops cash below your buffer. You see it 12 weeks early, not on the day.
Templates
Working formulas built in. Every template is a ready-to-use spreadsheet: type in your own numbers and the totals, warnings and charts update themselves. No formula skills needed.
The same weekly cash view I used in my own brand, built for small and medium-sized businesses, with extra lines for stock if you sell products. Enter what you expect to come in and go out, and it shows your cash in the bank for every week of the next quarter, with a red warning the moment you dip below your safety buffer.

Secure checkout. The file is emailed to you straight after payment. Buy all six in the Owner's Finance Kit for $79.

About me
Running my own brand taught me what no textbook did: cash gets stuck in stock long before the profit and loss shows a problem. I fixed it with bundles that still made a margin on every item, and weekly offers that kept cash coming in. Now I teach that to other owners, in plain words and simple spreadsheets.
