Evaluating 'Build vs. Buy' for Payment Infrastructure

Every payments business eventually faces the question: build the infrastructure ourselves, or buy it? Both answers can be right, and both can be very expensive when chosen for the wrong reasons.

The true cost of building

Building means owning more than code: PCI-DSS scope, security audits, scheme certifications and ongoing compliance obligations. These costs rarely appear in the first estimate.

The true cost of buying

Buying gets you to market faster but creates dependency. Pricing, roadmap and risk appetite belong to someone else, and switching later can cost more than building would have.

A practical rule

Build what differentiates you and what you must control for regulatory reasons. Buy or orchestrate the rest, behind an architecture that keeps providers replaceable.
