The customer
A curated antiques gallery in the heart of Andorra
SoissonBelles is a curated antiques gallery based in Andorra, specialising in carefully sourced European furniture, art, and decorative objects. Each piece is selected for its history, craftsmanship, and character.
The gallery already had a beautifully designed website built with Next.js — a multilingual catalogue with high-quality photography, detailed provenance descriptions, and a strong editorial voice. What they didn't have was a way to complete a sale online.
Visitors could browse the full catalogue, but to actually buy something they had to call, email, or visit in person. For a gallery selling internationally, this was a significant gap.
The challenge
A beautiful site with no way to pay
SoissonBelles had invested in building a website that reflected the quality of their collection. The last thing they wanted was to bolt on a generic checkout that felt disconnected from their brand.
The key challenges were clear:
No storefront needed. They weren't selling hundreds of products with carts and shipping calculators. They had a curated selection of unique, high-value items — many of them one-of-a-kind.
Brand integrity mattered. A customer browsing a 19th-century Louis Philippe mirror shouldn't suddenly land on a page that looks like it belongs to a different company.
Technical simplicity was essential. The gallery team aren't developers. Whatever the solution, it needed to work without ongoing technical maintenance.
The solution
Checkout as a layer, not a platform
KompiPay was designed for exactly this scenario — adding a payment layer to an existing website without replacing anything. The gallery keeps their site, their story, and their design. KompiPay handles the checkout.
The approach was straightforward:
We connected their Stripe account during a single onboarding call. SoissonBelles linked their existing Stripe account, giving them full control over their funds, payouts, and financial data.
We imported their catalogue from a CSV file. Product names, descriptions, prices, and images were mapped into KompiPay in minutes — no manual data entry, no rebuilding their catalogue from scratch.
We added a single script to their site. One line of JavaScript in their layout file. The existing “Buy Now” buttons on each product page now trigger a hosted checkout — branded, secure, and completely seamless.
The integration
One script, zero friction
The technical integration was intentionally minimal. SoissonBelles' developer added KompiPay's SDK script to the site's root layout — a single line. Each product page already had a “Buy Now” button component that was waiting for a payment integration.
When a customer clicks the button, KompiPay creates a checkout session via API, and the customer is redirected to a hosted payment page. The payment page pulls the merchant's branding — their name, their domain. The buyer never sees KompiPay.
After payment, the customer is redirected back to the merchant's website with a confirmation. Stripe handles the funds, KompiPay handles the flow, and SoissonBelles handles the relationship.

The result
Live payments from day one
SoissonBelles went from zero online payment capability to a fully operational, branded checkout in a single session. The numbers speak for themselves:
Onboarding to live: The entire process — Stripe connection, product import, SDK installation, and testing — took less than an afternoon.
No code written by the merchant: SoissonBelles didn't write a single line of payment code. Their existing “Buy Now” button was the only touchpoint.
Fully branded experience: Customers go from the SoissonBelles catalogue to a checkout that feels native. No third-party branding, no jarring transitions, no confusion.
International from the start: As KompiPay's first merchant outside the founding market, SoissonBelles proved the platform works across borders — Andorra, Europe, and beyond.
