Built against four documented complaints

We read 206 reviews of the two leading FBA calculators on the Chrome Web Store. Both fail at the same four things.

1. Accurate, auditable fees

"On every product I have checked the fulfillment fees are wrong. I lost a lot of money using this calculator."

The fee table is versioned in a file, and its effective date is on screen while you calculate. You always know which rate card produced the number.

2. Every field editable

"If only you have the option to edit the fulfillment fee since it is not accurate."

Manual override on any calculated value. Overridden lines are marked, so you never confuse your number with ours.

3. Zero server

"Amazon is not returning results for this product at the moment. Please try again."

All math runs client-side. There is no API to be down, no queue to wait on, and no per-user cost.

4. Zero login, pop-ups, telemetry

"You install, and even signup and still nothing."

No account, no interstitials, no analytics. Nothing about the products you look at leaves your machine. Read the privacy policy.
