About
Who builds Seller Profit Doctor, and why.
Felix S. Pavel · Founder
I built RestaurantDoctorAI first, a free profit check for independent restaurants. Online sellers face the same question with more fees in the way: listing fees, transaction and processing fees, ads that charge on sales they may have made anyway, labels that cost more than the buyer paid for shipping. Each one is small. Together they decide whether a shop keeps anything.
Seller Profit Doctor gives a seller on Etsy, Shopify or Amazon a fast, plain first look at where the money goes, for free: what each order keeps, the biggest losses, and what each fix is worth at their own numbers, if orders hold. If they want every step written out, they can buy the report once.
It doesn’t replace an accountant or bookkeeping software. It shows where to look first.
How it’s run
Three things I believe
They decide what the site shows you, what it charges and what it recommends.
You should see the problem before you pay for anything.
A lot of seller software wants your shop login, a free trial with a card, or a monthly plan before it shows you one number. We don't. Answer seven short questions and you see your grade and your biggest money losses, each with its fix, without an account or a connection to your shop.
Every number should show its math and its source.
Fees change, and many calculators online are out of date or wrong. Ours use fixed formulas on each platform's published fees, with the date each rule was checked and a link to where it comes from. No AI works out a number here.
You should pay once, not every month.
Most profit tools bill you every month, whether you look at them or not. Here the check-up and the calculators are free, and the full report is one payment that never renews, with a 14-day refund for any reason.

Follow the money
How the site makes money
The check-up, the calculators and the blog are free. These are the ways the business is paid, and nothing else is.
There are no ads and no paid placements, and we don’t sell your information to anyone. Seller Profit Doctor is run by Gomorra Labs LLC, an independent company: it isn’t owned by Etsy, Shopify, Amazon or any app that sells to sellers.
One-time reports
The check-up and the calculators are free. The profit report and the full audit are each one payment: no subscription, nothing renews and there's no account to cancel. Stripe handles the payment and the sales tax.
Purchases by AI agents
An AI assistant with a wallet can buy the same report for a seller through our paid agent server, paying with Stripe at the website's prices.
