Most wireless providers choose payment processors the same way they’d choose insurance: brand recognition, reasonable rates, and whatever IT says is easiest to integrate.

This checklist helps you ask the right questions to understand total cost of ownership, revenue impact, and whether your processor’s incentives align with your growth goals.

We’ve organized it by role because a CFO cares about different things than a CTO. But the underlying principle is the same: your payment processor should answer these questions confidently and transparently. If they don’t, that’s your signal that it’s time to make a change.

FOR THE CFO / FINANCE TEAM

Focus: Total cost of ownership and revenue impact

Pricing & true costs

☐ What’s our effective cost per successful transaction (including all fees, chargebacks, and fraud losses)?

RED FLAGS: When to walk away

Regardless of your role, these responses should concern you:

We can’t share that information” (about approval rates, decline reasons, or client benchmarks)
“That’s proprietary” (when asked about fraud models or decision logic—transparency matters)
 “You’ll need to ask your account manager” (and then the account manager doesn’t know)
Vague answers about uptime, reliability, or fraud guarantees
Inability to provide telecom-specific references or case studies
Pressure to sign quickly without answering technical questions
No clear escalation path for critical payment issues
“Industry standard” answers without specific numbers

GREEN FLAGS: What good looks like

Transparent data sharing about your performance and industry benchmarks
Telecom-specific expertise and references from similar clients
Clear fraud guarantees with real financial backing
Multiple acquirer connections with intelligent routing
Fast, confident answers to technical questions
Proactive performance optimization suggestions
Alignment of incentives—they succeed when you succeed
Real-time reporting and visibility into your payment data

Remember: Your payment processor should welcome these questions and answer them confidently. If they don’t, that tells you everything you need to know.
