hey, i have literally JUST posted about this in "making money" a few minutes ago... i have rebuilt a smm site i used to ran a while ago. and i am not good for making it work anymore, but i love the tech. so i was thinking to offer mine as a SaaS for either a fixed fee or commission... is that something you're looking for?
the checkout is better than buzzoid. nicer UI, great upselling, super fast checkout blabla... but i have put many hours into this. can't give it out for a low price. though, if you're making money, it's definitely the best option and worth discussing. let me know.
