Launch payments inside your software in weeks, not quarters.
Programmable wallets, multi-merchant onboarding, revenue share — all the infrastructure to embed BIG into your ERP, SaaS, or vertical platform without standing up a payments team.
Built for ISVs who want payments without becoming a payments company.
White-label everything
Your brand on the merchant dashboard, onboarding flow, and checkout. We're the rails — you're the relationship.
Revenue share with real numbers
Published pricing tiers tied to volume. No mystery splits, no annual renegotiation. Quarterly payouts on the same rails BIG processes on.
Onboarding API + hosted forms
Build merchant onboarding directly into your product or drop in our hosted form. KYB, document upload, underwriting handoff — all included.
Programmable wallets
Issue merchant or sub-merchant wallets with the same API used by our enterprise customers. Hold funds, route payouts, sponsor gas.
Underwriting included
You don't take risk. BIG underwrites every sub-merchant, owns the compliance posture, and handles the bank relationships.
Dedicated BD + integration
Named BD contact, a Slack/Teams channel with our integration team, and a deployment partner on the call when you ship.
Application to launch in 2–4 weeks.
