Bigbug Haha, some posts just stick with me!
I do get what you're saying, but I still struggle to actually see the benefit. If you had six invoices for 1k each, you'd actually pay a tiny bit more in Stripe fees than one transaction for 6k. This doesn't actually save you any money, you just notice it more as it's a bigger fee…
Worth mentioning that if you process a large volume of payments then Stripe can probably offer you lower fees?
