Quick Answer

Infographic: Peptide marketplace multi-vendor payments — splits, seller KYC, and facilitator MID strategy

Peptide marketplace payments need clear seller KYC, per-vendor payout logic, and an underwriting story that explains who owns fulfillment liability. Some models use marketplace facilitator processing; others require seller of record MIDs. There is no universal hack — disclose flows up front. Read peptide compliance hub before scaling third-party sellers.

Bold takeaway: *If buyers cannot tell which seller fulfilled the order, chargebacks will not tell your risk team either.*

Architecture Patterns

Facilitator MID with controlled seller onboarding
Separate MIDs per major seller when concentration is high
Payout timing aligned to delivery confirmation webhooks

Frequently Asked Questions

Can Stripe Connect work for peptides?▼

Stripe’s policies generally restrict peptides; assume mainstream aggregators are a poor fit — specialist programs evaluate case by case.

What breaks marketplace underwriting?▼

Opaque seller onboarding, missing COAs for third-party SKUs, and commingled fulfillment without tracking.

How are reserves calculated?▼

Often at facilitator level — model worst-case chargebacks before you onboard many sellers at once.
