You can go as simple as hiring some fresh out of school IT nerd to put all the items into a spreadsheet or simple database table, or go more robust and purchase a full blown inventory system. There are tons of options out there.

I would actually go with some socially awkward 20 yr. old IT nerd with a laptop and MYSQL. Give him a halfway decent per hour pay, or a nominal salary. It would be fairly cheap and easy to set up. If it turns out to not be what you are looking for it’s easy enough to take a bigger step and pay for some actual inventory software.

What is a “protection fee?” Is that insurance? Why would you pay $134 for a $32 item?

Not one single bit of this makes any sense.
