Should I Sell a Company’s Products on my Ebay Store?

I’ve been approached by a company that sells accessories and software that fit perfectly within my primary eBay categories (computers and IT equipment). They’re looking to expand their sales channels but don’t have a presence on eBay, so they want to partner with someone reputable (I’m a top-rated seller with over a decade of experience, 3,500+ feedback reviews, and a 99.6% positive rating).

I’ve done my homework, and they’re legit, with a solid reputation. They just haven’t tapped into the eBay marketplace yet and want to use my platform to do so. I have over 1,500 subscribed buyers in the computer category, and adding their products could boost my revenue since I’d be handling all the listings, customer service, and admin. They’d just handle the shipping.

So far, I can’t see anything wrong with a symbiotic relationship like this, but does anyone have experience with something similar?
