Free tools
Numbers you can check, without a sales call.
Five working tools built from the questions clients actually ask us. No account, no email gate, and none of the numbers you type leave your browser.
Five tools
Built to be checked
Every formula is visible, and nothing you type is stored or sent anywhere.
- No account
- No email gate
- Browser only
Why these are free and ungated
A calculator behind an email form is a lead magnet pretending to be a tool. These run entirely in the browser, store nothing and ask for nothing. If one is useful, that is the advertisement.
How to read them
A calculator is only as honest as its inputs
Each tool shows the formula it uses and asks for the figures it cannot know. Where a number changes often, such as Amazon's fee schedule, you paste the current one rather than trusting a table that was accurate a year ago.
No hidden constants
Percentages and fees are visible in the breakdown, so you can check the arithmetic rather than accept it.
No invented benchmarks
We do not compare your margin to an industry average we cannot source. Your cost structure is the benchmark.
No data leaving the page
Everything is computed in the browser. Clearing the tab removes it, and nothing is logged.
Tell us where the manual work is
A 30-minute call. We map the process, tell you what we would automate or build first, and what it costs. No retainer before you agree the scope.
- No retainer before scope is agreed
- Written plan you can act on alone
