Why the workbooks are paid when the calculators are free
The free calculators remain free. A workbook solves a different problem: it keeps multiple assumptions together, stores scenarios, tracks changes over time and gives you a file that can be updated whenever the numbers change.
Each product includes editable inputs, built-in formulas, dashboards, notes and a purchaser licence. The workbooks provide planning estimates and do not replace tax, accounting, legal, payroll or financial advice.
Delivery and compatibility
Checkout is processed securely by Stripe. After payment, the buyer is redirected to a secure download page with a temporary 24-hour link. Current versions of Microsoft Excel are recommended.
Read the digital download, licence and refund policy before purchasing.
