Sellfy says "no transaction fees" ΓÇö but caps your annual sales at $10k on the Starter plan, then forces you to $79/month the moment you exceed it. Payhook charges 0% platform fees at any volume and includes a full write API. No tier jumps. No ceilings.
Sellfy's "no transaction fee" is real ΓÇö but the revenue ceiling is the catch. Hit $10k/year and you're on a forced upgrade to $79/month, regardless of whether your margin supports it. Payhook has no caps. You pay Stripe's standard processing rate on every sale, nothing more.
