E-commerce & payment services

Retail, marketplaces, and payment service providers — lower cost, stronger authentication, measurable conversion lift.

Card networks still dominate online checkout. They stack intermediaries, push scheme fees into the 1.5–3% range, stretch settlement to T+1–T+3, and leave merchants exposed to card-not-present fraud and chargebacks. StixBNK routes compliant account-to-account (A2A) flows over PSD2-style open banking so shoppers can Pay by bank with SCA at their institution — while you receive webhooks, references, and reconciliation data in one API layer.

Use case 1

Instant A2A payment at checkout

Context

Traditional e-commerce stacks depend on Visa, Mastercard, and acquirers. That implies multiple hops, blended pricing, and fraud models optimised for cards — not for high-trust bank rails.

  • Several intermediaries between shopper and settlement
  • Scheme + interchange + acquirer margin (often 1.5–3% blended)
  • CNP fraud, chargebacks, and dispute handling overhead

Merchant pain

  • Compressed margins after payment fees
  • Slow settlement (T+1 to T+3)
  • High card-not-present fraud exposure

What StixBNK enables

Direct payment initiation from the customer’s bank account via regulated open banking APIs. The payer authorises in their bank app or web session (SCA); funds move account-to-account with a clear payment reference tied to your order.

Technical flow

  1. Checkout presents Pay by bank alongside existing methods.
  2. StixBNK creates a payment initiation request with amount, creditor, and reference.
  3. Customer is redirected to their bank (OAuth-style handoff + SCA).
  4. Strong authentication — biometrics, device signing, or OTP as required by the ASPSP.
  5. Bank confirms authorisation; status propagates to StixBNK.
  6. Webhook notifies your OMS / ERP so you only fulfil on authorised or settled states.
  7. Settlement can be near real-time or same-day depending on rail and geography.

Use case 2

Intelligent checkout with bank-sourced data

Friction

  • Long address and IBAN forms
  • Industry-average cart abandonment around 70%
  • Manual errors and support tickets

Approach

With consent, connect the shopper’s bank once via StixBNK to retrieve verified identity fragments, IBAN, and structured address data — then autofill checkout and immediately initiate payment.

Flow

  1. User selects Checkout with bank.
  2. Secure connection through StixBNK (AIS / identity scopes as licensed).
  3. Normalised payer details returned to your front end.
  4. Fields pre-filled; user confirms in seconds.
  5. Payment initiation completes the journey in one session.

Use case 3

Recurring payments & mandates

Why cards churn

  • Expired, lost, or reissued cards
  • Involuntary churn on subscriptions
  • Retry logic and dunning cost

Bank mandates — SEPA Direct Debit, variable recurring open-banking consents, or hybrid models — tie billing to an account that changes less often than a card. StixBNK stores consent artefacts, surfaces mandate status in your dashboard, and fires webhooks on success, failure, or mandate revocation.

Flow

  1. Customer authorises a mandate in a hosted or embedded flow.
  2. StixBNK persists consent metadata and compliance timestamps.
  3. Scheduled or event-triggered collections execute per your rules.
  4. Real-time notifications feed your billing engine.
