Why BigCommerce peptide stores need a custom gateway
BigCommerce supports more than 65 pre-listed payment providers, but none of the default options underwrite peptides, SARMs, or research chemicals. The platform does allow custom payment gateways through its Custom Payment Provider API, which is how Peptide Payments connects. Your BigCommerce storefront stays untouched; the high-risk gateway sits behind checkout and routes transactions to an acquirer that already underwrites your products.
How the BigCommerce Integration Works
Setup runs in 4 steps and most peptide merchants are processing through BigCommerce within 24 hours of submitting a complete application.
- Apply and get approved for a high-risk merchant account
- We connect Peptide Payments as a custom payment provider in BigCommerce
- Cards, ACH, and digital wallets are enabled inside your existing checkout
- Built-in reporting flows back into the BigCommerce dashboard
Pricing
The BigCommerce integration uses interchange-plus pricing, average effective rates land near 2.4% plus $0.10 per transaction for qualified peptide retailers, versus 3.5%–4.5% on flat-rate gateways like Stripe. There are no monthly minimums, no PCI fees, and no integration fees.
