More on the way
We're shipping new tools every week. Here's what's up next - each will get its own page when it ships.
Why these are free
We use these calculators internally - every Tacey customer pulls them up at some point during onboarding to size up the impact. Putting them on a public URL costs us nothing extra and saves the next merchant an evening of spreadsheet work.
No signup. No email gate (until you hit your daily limit on the metered tools). No upsell modal in the middle of using them. If you decide Tacey itself is interesting after running the math, the install button is in the same place it always is.
Want every order on your store running through this kind of math automatically?
