How to choose payments & billing apis without guessing
Payment processing platforms are essential for businesses accepting digital payments, but choosing the right one requires careful evaluation of your technical capabilities, transaction patterns, and growth trajectory. Developer-focused teams benefit most from Stripe's extensive APIs, while SMBs may prefer Square's simplicity. International businesses must account for surcharges (1.5%+), and high-volume merchants should negotiate IC+ or custom pricing to avoid paying premium rates at scale.
