Common situations HelpSeller helps you solve.
★★★★★"I had no idea how much Etsy was actually taking from my sales. After using this, I raised my prices by 15% and my profit doubled."
★★★★★"The goal tracker is exactly what I needed. I could see I needed 140 sales/month to hit $2k — now I have a real target to work toward."
★★★★★"The scenario comparison convinced me to go premium. Comparing $20 vs $35 side by side made the decision obvious — I was leaving money on the table."
Every sale you make without knowing your real margin is money you're leaving on the table. Takes 30 seconds to set up.
