Multi Platform Auction Listing Tracker

Is there a selfhosted solution for tracking my auction postings across multiple platforms? I will often post the same items on eBay, Postmark, Mercari, Etsy, etc simultaneously. Keeping track of all listing can be difficult (when I sell and item on one platform I need to find the listing on the other platform to deactivate which gets exponentially more difficult the more items i have listed).

I record a lot of data like what I originally paid for the item, when I purchased it, how much I sold it for, shipping costs, auction site's cut they take, my ultimate profit on the item and lots of other data. My spreadsheet method is getting out of hand.
