💼Business Tools
Business tools for the operational numbers a small business runs every week: average order value, customer acquisition cost, churn forecasting, SaaS plan break-even, margin and markup, hourly rate setting for service work, time-clock tracking, and invoice generation. The math is the standard textbook math; the value is in surfacing the inputs side-by-side so a comparison stays apples-to-apples and the levers that actually move the result are visible. The common misconception that costs the most money is conflating margin with markup; they sound similar but a 50% markup is only a 33% margin, and a 50% margin requires a 100% markup, which the Margin and Markup Calculator shows side by side. A second common mistake is using gross AOV instead of AOV-net-of-discounts when comparing channels; the AOV Calculator surfaces both. If you are new to the category, start with the Hourly Rate Calculator if you bill for your time (it works backward from your target take-home), the AOV Calculator and CAC Calculator together for any ecommerce business, and the Invoice Generator for the actual document. The SaaS Churn Forecast and SaaS Tiered Plan Break-Even Calculator are the right starting point for subscription businesses that want a clear picture of their unit economics before raising or repricing. None of the tools require an account; the outputs are yours to copy or download.
