Choosing a payment processor

Three things that matter when you're choosing a payment processor

Not all payment processors are the same. Before you sign up, check these three things — they're what separates a processor that stays with you from one that doesn't.

Is the processor actually licensed?

A licensed payment processor is supervised by a financial regulator — which means accountability, stability and compliance. MMG is supervised by the Czech National Bank. Many processors aren't licensed at all.

Does the processor use multi-acquiring?

A single-acquirer processor is one outage away from taking your revenue offline. A payment processor with multi-acquiring and smart routing keeps transactions flowing even when one route fails.

Will the processor stay open for your category?

Many payment processors accept your business then terminate when volume grows or chargebacks move. The right processor underwrites your category properly from day one — not as a favour, but as policy.

The difference it makes

The wrong payment processor is expensive. The right one isn't.

The wrong payment processor

  • Approved, then closed when volume picks up
  • High decline rates silently losing revenue
  • Surprise reserves and withheld settlements
  • No one who understands your vertical
  • Re-applying and re-integrating every year

MMG as your payment processor

  • Underwriting built for your category from day one
  • 94%+ approval rates via multi-acquiring routing
  • Transparent settlement, agreed upfront
  • A specialist who knows your vertical
  • A long-term relationship, not a revolving door
What's included

Everything a payment processor should deliver

One licensed processor for the gateway, acquiring, payment methods, settlement and support — all from the same team.

Licensed-PI underwriting

Supervised by the Czech National Bank — we open accounts for all categories, including high-risk, as core business.

Multi-acquiring & routing

Intelligent cascading across acquirers maximises approval rates and keeps your account live if one route goes down.

Cards, wallets & APMs

Visa, Mastercard, Apple Pay, Google Pay, PayPal, bank transfers, local schemes and crypto in one checkout.

Recurring billing

Card-on-file and subscription processing for SaaS and membership businesses — with smart retry logic.

Multi-currency settlement

Accept and settle in 30+ currencies across international markets from one integration.

Fraud & chargeback tools

3DS2, velocity rules and dispute support keep chargeback ratios inside scheme thresholds.

Every vertical

A payment processor for the categories others avoid

Most payment processors decline or restrict the same categories — iGaming, adult, nutraceuticals, CBD, travel and lending. MMG was built around these verticals, not in spite of them.

  • iGaming & betting — MCC 7995, 7994
  • Adult & dating — MCC 7273, 5967
  • Nutraceuticals & CBD — MCC 5122, 5499, 5968
  • Travel — MCC 4722, 7011, 4511
  • Online lending — MCC 6012, 6051
  • Mainstream e-commerce — all standard MCCs

Payment Processor FAQ

Questions about choosing a payment processor

What is a payment processor?
A payment processor is the company that handles the technical and financial chain between your checkout and your customer's bank — authorising transactions, managing acquiring relationships and settling funds into your account. MMG is a licensed payment processor and payment institution, which means we're responsible for the entire chain rather than relying on separate third parties for each part.
How do I choose the right payment processor?
Look for three things: licensing (is the processor supervised by a financial regulator?), infrastructure (does it use multi-acquiring to protect approval rates?) and vertical fit (will it stay open for your business category as you scale?). A licensed processor with multi-acquiring and transparent underwriting is the foundation of a stable, long-term processing relationship.
What's the difference between a payment processor and a payment gateway?
A payment gateway is the technical component that captures and routes payment data at checkout. A payment processor is the broader entity — licensed, regulated, with acquiring relationships — that actually moves the money. MMG is both: a licensed payment processor with its own gateway, so you deal with one partner for the entire flow.
Does MMG work with high-risk businesses?
Yes — MMG specialises in the categories that mainstream processors decline, including iGaming, adult, nutraceuticals, CBD, travel and lending. We underwrite each business individually rather than applying blanket restrictions. Tell us your category and we'll confirm what we can process and on what terms.
What payment methods does MMG process?
MMG handles Visa, Mastercard, Apple Pay, Google Pay, PayPal, SEPA bank transfers, local payment schemes across 30+ markets and crypto — all through a single integration, so you don't need multiple processors for different payment methods.
How long does it take to switch payment processors?
Technical integration via our API or PCI-DSS hosted forms typically takes a matter of days. Your new account manager handles onboarding and documentation in parallel to keep the timeline short. We've helped businesses switch processors with minimal disruption to live transaction volumes.
What does MMG charge as a payment processor?
Pricing as your payment processor depends on your vertical, transaction volumes, processing history and the payment methods you need. We build a proposal tailored to your business rather than publishing a standard rate — the terms you see are the terms that apply to you. Submit a request and we'll come back with specifics, usually within one business day.
