Was curious if anyone has had any luck with any selling apps that run cross platform? like I’d love to be able to list once and have it post on ebay/mercari/fb marketplace etc. all at once. and remove it from all when its sold from one? would be way quicker to list stuff on multiple platforms that way. If anyone has any experience with something like this let me know of good app to use or which to stay away from and why. Thank you. Any other selling tips appreciated.
