B2B with $500+/month contracts requires a sales motion, not just a self-serve flow. Build a 'Contact sales' flow from day one and be ready for security reviews, procurement, and contract negotiations.
Enterprise customers require SAML/SSO — they won't onboard without it. WorkOS or Clerk handle this at $0–$99/month for lower tiers. Budget for it in v1 if enterprise is your target.
Enterprise buyers require audit logs — who did what, when. Store all user actions with timestamps, user ID, and IP address. This is a security requirement, not a nice-to-have.
Rough estimates per feature. Our fixed-price MVP bundles all of these — see the full B2B Platform cost guide.
