Everything you need to understand your reseller profit.
ProfitCheck is designed to help sellers move beyond guesswork and understand the real financial outcome of each sale.
Calculate what you actually keep after item cost, shipping, marketplace fees, promos, discounts, taxes, and other expenses.
Quickly see whether a sale is a great profit, low margin, break-even, or a loss.
Start with editable fee estimates for marketplaces like eBay, Mercari, Etsy, Amazon, Facebook Marketplace, or custom setups.
Organize checks by category such as trading cards, sneakers, electronics, clothing, collectibles, auto parts, and more.
Save profit checks to your account so you can search, sort, review, duplicate, edit, and track them over time.
Review total revenue, total cost, fees, net profit, average margin, ROI, best items, worst items, and category performance.
From calculator to profit intelligence.
ProfitCheck starts with simple profit calculations, then turns saved checks into useful insights. Over time, your data can show which items, categories, and marketplaces are actually worth your time.
