A DECISION FRAMEWORK

01 / 08

Should you
be
both
issuer
and
acquirer?

A decision framework
for payment-led businesses.

WHAT IT MEANS

02 / 08

Instead of relying on separate players
for issuing and acquiring, a dual-role model
brings cardholders, merchants and processing
into one controlled payment ecosystem.

Issuing +
acquiring
means controlover both sides.

WHY IT MATTERS

03 / 08

The upside: margin, data and control.

  • MARGIN

    01

    Capture more of the payment economics
    instead of sharing fees.

  • DATA

    02

    See both consumer and merchant
    behaviour in one view.

  • CONTROL

    03

    Optimise authorisation, settlement,
    fraud
    and experience.

0.0–0.0%

Potential interchange economics can reach ~1.3–1.5%.

WHEN IT MAKES SENSE

04 / 08

Dual-role works
when the model
already
supports it.

  • 01

    Vertical specialisation

    Niche density makes the infrastructure worth building.

  • 02

    Platform or marketplace

    Two-sided flows: split payments, escrow, settlement.

  • 03

    High transaction volume

    Billions processed; internal flows can improve unit economics.

  • 04

    Regulatory or localisation

    Data-localisation markets may reward keeping
    capabilities under one roof.

WHEN IT DOES NOT

05 / 08

The wrong time
to integrate is
before you
have scale.

  • 01

    Not enough volume

    Too few transactions to capture internal value.

  • 02

    Not enough capital

    Reserves and licences you cannot yet resource.

  • 03

    Weak synergy

    Issuing and acquiring sides
    that do not
    reinforce each other.

REALITY CHECK

06 / 08

You do not toggle this on.
It is licences, capital, risk.

  • 12–24

  • €5M+

  • PCI DSS

    fraud monitoring and reporting
    are non-negotiable

PROOF

07 / 08

Three models that show the logic.

  • AMEX

    Closed-loop pioneer: issuing, merchant acceptance and processing within one ecosystem.

  • SQUARE

    Vertical integration: from merchant payments
    to broader financial services.

  • PAYPAL

    Digital-first scale: existing relationships help
    expand acquiring capabilities.

PUBLIC EXAMPLES · NOT CLIENTS

THE REAL QUESTION

08 / 08

Not whether you
can build it.
Whether
the
economics justify
the complexity.
