sharpfee is an independent fee comparison for online sellers — people who sell on marketplaces like Etsy and eBay, or run their own Shopify store, and want to know, in plain numbers, what each channel costs per month.
One flagship tool at launch: the Marketplace vs Own Store Monthly Breakeven Planner. It compares monthly fees, net profit, and margin across Etsy, eBay, and your own Shopify store for one identical item, and shows the order volume where your own store becomes cheaper on fees alone. Every fee it uses is listed, sourced, and dated on the Fee Index. The method is fully written out on the Methodology page.
More tools in the same seller niche will follow only on evidence — what sellers actually use and ask for — not on a pre-set list of unrelated tools. Freelancer, creator, advertising-budget, and tax tools are not part of this site's niche and are not planned here.
Not affiliated with, endorsed by, or sponsored by Etsy, eBay, Shopify, or Amazon. Not financial advice. Not a promise of traffic, sales, or earnings. Not a substitute for checking your own seller dashboard — categories, plans, and fee schedules change, and your category may differ from the most-common rates used here.
