How to Choose the Right Payment Method: Practical Tips for Merchants

Updated on 26.05.2026.

 Choosing the right payment method is key to the success of any business. It directly affects costs, payment speed, and customer satisfaction. Here’s how to make the right choice - quickly and easily.

Analyze the costs

Payment methods come with different fees - processing fees, commissions, and hidden costs.

Calculate your monthly payment volume and compare the fees. Watch out for hidden charges such as refunds and subscriptions. Direct bank payments (like IRIS Pay) come with lower fees because there are no intermediaries.

Evaluate payment speed

The faster you receive your money, the healthier your cash flow.

Card payments can take days to be processed. Direct bank payments are instant or involve minimal delay.

Think about customer convenience

A simple and fast checkout process increases the chances of completing a purchase.

Offer mobile and online payment options. Customers prefer paying directly from their bank account, without unnecessary steps.

Security and regulatory compliance

Payments must be secure and compliant with regulations such as PSD2 and GDPR.

Choose licensed solutions with a high level of security. IRIS Pay provides security and transparency for every transaction.

Easy integration and support

How easy is it to connect the payment method to your website or system?

Choose solutions with well-documented APIs and fast technical support. IRIS Pay offers easy integration and reliable support, suitable for SMEs.

How to Choose a Payment Method Based on Your Business Type?

Different business models have different needs. An online store does not have the same requirements as a B2B company or a subscription-based service.

Which payment methods are most suitable for online stores?

For online commerce, the most important factors are:

• fast checkout
• low transaction costs
• seamless mobile payments
• high conversion rates

Suitable options may include:

• card payments
• digital wallets
• bank transfer payments for online stores
• A2A solutions

For online stores with higher transaction volumes, lower processing costs often have a direct impact on profitability.

How to Choose a Payment Method for Services and Subscription Businesses?

For service-based and subscription models, the main priorities are:

• recurring payments
• automation
• easy invoice management
• predictable revenue streams

In this case, convenience and consistency of the payment process are often more important than offering a large number of payment options.

Which Solutions Work Best for B2B Payments?

B2B payments often involve larger amounts and more complex processes.

Key factors include:

• transparency
• security
• easy tracking
• fewer intermediaries
• lower costs

Account-to-account payments are becoming increasingly preferred for B2B payments because they enable a more direct and efficient payment process.

 Choosing a payment method is a strategic decision with a significant impact on your business. Pay close attention to fees, speed, convenience, security, and integration to ensure the best outcome for you and your customers.
