Stripe is an exceptional piece of developer infrastructure. Their APIs are world-class and their documentation is legendary. But for bootstrapped founders and indie hackers, Stripe's unbundled pricing model creates a silent profit leak that compounds every month.
Headline Rate vs Realized Effective Rate
Most founders calculate their unit economics assuming payment processing will consume ~3% of revenue. When you audit your actual end-of-month bank deposits against gross billing volume, the realized effective fee is almost always over 7%.
