Small Business Tools for Pricing, Pay, Invoices, and Cash Decisions
Price jobs, check margins, estimate pay, and make everyday business decisions with private browser tools that keep formulas and assumptions visible.
Built for owners, freelancers, solo operators, bookkeepers, and side-hustle sellers. Inputs stay local unless a tool clearly says otherwise.
What can this collection help you decide?
This reproducible table models hypothetical meeting cost across participant counts, durations, and loaded hourly-cost assumptions. It includes an annual weekly recurrence to make the compounding effect visible. It is not a claim about an employer’s actual compensation or productivity.
