FAQ

Good questions.

Does it connect to my eBay or Poshmark account?+

No. It doesn't log in to any marketplace. Add items and sales by hand in a few taps, or import a CSV from your spreadsheet.

Are the fees exact?+

They're estimates from editable presets. If your order shows a different fee, type the exact amount for that sale, or change the preset.

I buy in bulk. Can it split the cost?+

Yes. Bulk lots split the price evenly, by estimated value or by weight.

Can you see my data? Is it uploaded?+

No. Everything stays in your browser on your device. Nothing is sent to me or anywhere else.

Does it work on my iPhone?+

Yes, use the hosted version. After you buy, open your private app link in Safari and tap Share, then Add to Home Screen. It opens full screen and works offline after the first visit. We test in Google Chrome, including phone-size screens. If anything doesn't work on your device, message us.

What do I get after paying?+
