Best way to track profits and losses on eBay?

Hello Reddit!

I’ve been selling on Amazon for a while and use a great little app called Sellerboard to track my profits, losses, fees, and all that fun stuff, it makes life so much easier!

Now, I’m starting to sell on eBay too, but I haven’t found anything similar that can automatically track sales, fees, and expenses. Does anyone know if there’s a tool like this for eBay? Or, if not, is there another easy way to keep track of everything manually?

At the moment, I buy all my postage through Royal Mail Click & Drop, which makes it a bit trickier to calculate everything accurately. Any tips or recommendations would be massively appreciated!

Thanks in advance!
