What is the best way to manage multiple ebay accounts?

Noob on BH, so apologies upfront.

I've got a few eBay accounts, 2 of which are quite mature.
I'm trying to start a few more accounts so I can offer more products and monopolise my niche.
What is the best way to manage all accounts?
Software, tools, techniques.
I'm currently downloading browsers on my windows machine and just logging in.
I've got 4 accounts in all, but want to grow more accounts, so I have say 10, 15 or even 30.
Eventually might even consider buying some stealth accounts, but need to manage them all.
The products are all legit and I buy from a wholesaler, it's just that competition is fierce for other similar products.
Any suggestions most welcome.
Thanks

eBay can be really finicky about multiple accounts, surprised you haven't hit the ban hammer yet.

There's no decent eBay software out there IMHO can to be honest you could do with beginning to think in terms of a VPS to access your sites.

I know that's going to slow you down rather than speed you up but in the long term it's the only way.

Chrome has sandboxing, which means you can create new profiles that have individual settings. Which is important because you want each profile to have it's own ebay account logged in every time you start it. Use different proxies and user agents for each profile to keep anonymity. Public proxies are slow within a minute of being available and likely blocked/redflags so just get private ones they are like $1 each per month.

I have a dedicated linux box that is running dozens of chromes botting followers, favorites and likes 24/7 it's great. Fortuantly for me social media sites don't care about multiple accounts on one network. But Ebay might.
