Reselling on multiple platforms means juggling different fee structures, shipping costs, and ad spend. These apps help resellers track inventory, calculate per-item profit after fees, and price listings by target margin — so you always know which items are actually making money.
Most resellers underestimate their true per-item profit. After eBay fees, Etsy transaction fees, Offsite Ads, PayPal fees, shipping supplies, and ad spend, a 'good' sale can actually be a money-loser. The apps here do that math for you, instantly. They're local-first (your inventory and financials stay private on your device), and they don't take a cut of your sales.
