Debit-Linked BNPL, Built Without a Single New Lending License

The Client 

A Debit Platform Racing Standalone BNPL Providers for the Same Dollar

• A US financial services technology provider runs debit card programs for thousands of banks and credit unions. 

• Every quarter, more of that spend leaks to standalone Buy Now, Pay Later apps. 

• The client wanted BNPL built directly into its own debit rails, not bolted on as a side product. 

The Context 

Banks Want BNPL. Building It Alone Takes Years and a Lending License

• Standalone BNPL providers pull spend straight out of a bank’s existing debit relationship. 

• Building BNPL from scratch means new lending infrastructure, new underwriting risk, and a new regulatory license. 

• Most banks and credit unions do not have eighteen months or a risk appetite for that build. 

• The client needed a way to hand its bank partners real BNPL capability without asking them to become lenders overnight. 

What Opus Engineered 

Full Ownership of the BNPL Build, From Journey Map to Go-Live

• Opus took full end-to-end ownership of the BNPL enablement program, from journey definition through testing, stakeholder coordination, and operational handoff. 

For the Client

• An AI-infused software delivery lifecycle compressed requirement design, use case definition, and testing into one continuous workflow. 

• The team documented every BNPL journey across authorization, clearing, funding, servicing, and exception handling. 

• Integration spanned transaction processing, loan registration, reporting, and reconciliation, wired through the Credit API, Digital API, Dispute Expert, Billing, and Card Expert data reporting layers. 

For the Client’s Customers (Banks & Credit Unions)

• Opus built a pay-over-time Partner Card SDK straight into their digital channels, covering consent flows and account linking. 

• The team delivered an embedded BNPL hub experience with both pre-purchase and post-purchase installment plan options. 

The Result
