A BNPL operator, composed in six weeks.
Reference architecture for launching a Buy-Now-Pay-Later operator in EU or UK on the Klyqo Banking OS. Persona + Alloy for KYC and fraud, Marqeta or Stripe Issuing for virtual cards, Modern Treasury for settlement, journey templates for approve · issue · collect. Connect to merchants via partner API, run the credit decision in 300 milliseconds, scale the book without re-platforming.
BNPL is a credit product disguised as a checkout button.
A successful BNPL operator runs three things excellently: sub-second underwriting at point-of-sale, instant card issuance for “buy now”, and disciplined collections for “pay later.” The merchant integration is the front door. The book is what kills you or compounds you.
Five layers + two rails. Klyqo composes them.
BNPL adds two things to the standard bank stack: a merchant-facing API at the channel layer, and tight integration between fraud + credit decisioning + card issuance at the marketplace layer. Klyqo orchestrates them as one journey, settled in 300ms, with audit trail for the regulator.
consumer-credit affordability checks, audit trail, transaction monitoring
real-time decisioning, NPL monitoring, dynamic limits
Approve · issue · settle, end to end in 300 milliseconds.
A consumer hits “Buy now” on a merchant’s checkout. Klyqo orchestrates approve → issue → settle as a single typed journey; the customer sees one click; the merchant sees a confirmed payment; the bank sees a regulator-ready audit trail.
What you pick from the marketplace.
A BNPL operator in this configuration uses five marketplace providers. Persona is production today; the others are in flight or scoped on request. The build sequence promotes them in the order the journey needs.
Honest about the build.
BNPL is brutal on the book. The three things that matter are (1) decision latency under 300ms, (2) fraud + credit signals concatenated correctly, and (3) collections discipline before the loss compounds. Klyqo orchestrates all three, but the underwriting policy and the warehouse line are yours.
What you bring: the FCA / EBA licence, the warehouse funding, the merchant agreements, the underwriting policy, the consumer-credit compliance posture. What Klyqo brings: the runtime, the marketplace adapters, the journey templates, the sub-300ms orchestration, the audit log. What we figure out together: which fraud + bureau combo for your specific market, which card issuer for your geography, which settlement terms per merchant tier.
If you’re launching a BNPL operator in EU or UK and want to ship a real product in six to eight weeks instead of a year: this blueprint is shipping toward your use case. Talk to us before you scope the build yourself.
