Does anyone use Quicken to keep track of expenses for tax purposes? Or do you let an accountant do all the work?

I have been asking ChatGPT some reselling questions lately and one of the things it suggested surprised me. It said if you sell similar from an older item to wait 24 hours until relisting it because if you sell similar and relist it immediately it can somehow be attached to the older listing even though it has a new item number. I know this is the case if you "relist" but I thought it was different for "sell similar." Has anyone else come across this suggestion or know if it has any validity?

I’m finally spreading my wings and listing on Mercari as well as eBay. Any advice on selling on Mercari appreciated.

.... to all my reselling friends here. May your holiday be bright and your New Years be safe and happy.

I have 46 listings on Poshmark and I can’t figure out how it works with friends and sharing listings with others in order optimize sales?! I have no idea what I’m doing!!
