Actually should have clarified, I meant submissions not general posts. I just searched their profile's submissions and found seven mentioning proxybase. I actually didn't check their comments.
Stripe is a payment processor which basically means they process the payments for you, so you do have to figure out the tax part yourself (or use their tax product, but you're still the one responsible for it.)
Lemon Squeezy is a merchant of record which means _they_ act as the merchant and sell the product to your customer. So they'll collect VAT and make sure it lands in the pockets of the right country etc. and will pay you only the remainder (minus their cut).
Since Lemon Squeezy uses Stripe under the hood as their payment processor you had to basically pay a cut to two companies if you used Lemon Squeezy but in exchange you literally have to worry about nothing. You just get a nice B2B reverse invoice and don't have to break your head around world wide (and especially EU) tax laws.
I really hope Stripe will double down on the whole MoR thing, it makes processing payments online so much nicer and less annoying.
