Why Squarespace peptide stores need an off-platform checkout
Squarespace does not expose a custom payment gateway API the way BigCommerce or Magento do, so the standard play for peptide merchants on Squarespace is a hybrid: Squarespace handles the storefront, product detail pages, and SEO; Peptide Payments handles checkout via a branded hosted page or embedded payment form. The visitor never sees a hand-off, and your acquirer is one that already underwrites peptides and research chemicals.
How the Squarespace Integration Works
Setup runs in 4 steps and most peptide merchants are processing through Squarespace within 24 hours of submitting a complete application.
- Build or keep your Squarespace storefront and product pages
- Apply and get approved for a peptide-friendly merchant account
- We replace the Squarespace Add-to-Cart button with a branded hosted checkout
- Cards, ACH, and digital wallets all run through the high-risk MID
Pricing
The Squarespace 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.
Who the Squarespace Integration Is Built For
- Squarespace peptide and SARM brands
- Squarespace supplement startups
- Squarespace creators selling research compounds
- Squarespace sites blocked by Stripe
- Squarespace stores that need ACH
Frequently Asked Questions
Do I have to rebuild my Squarespace store?
No. You keep your existing Squarespace site, theme, products, and SEO. We only replace the payment gateway behind checkout.
How long does the Squarespace integration take?
Most peptide merchants are live on Squarespace within 24–48 hours of approval. The plugin or custom-gateway setup itself takes under an hour.
Does this support recurring billing and subscriptions on Squarespace?
Yes. Card-on-file, recurring billing, trial-to-rebill, and 1-click upsells are all supported on the same merchant account.
