Questions

Does it connect to my eBay or Poshmark account?No. You type sales in, or import a CSV. Nothing logs into your selling accounts.

Does it sync between my phone and laptop?Not automatically. Save a backup on one device and open it on the other.

What happens if I lose my phone?Whatever was in your last backup comes back. Anything after it is gone, which is why the app nags you to back up.

I prefer spreadsheets.The download includes a Google Sheets / Excel version too.

Is it tax software?No. It gives you clean totals; your accountant or tax tool does the rest.
