Any online store, SaaS product, or digital platform eventually faces the same fundamental question: how to properly collect payments from customers. The market offers dozens of solutions, and navigating the terminology can be genuinely confusing. This article breaks down the key concepts: the difference between a payment gateway and merchant acquiring, which payment methods are worth enabling, and what to look for when reading reviews of payment providers.
Payment Gateway vs. Merchant Acquiring: Understanding the Difference
These two terms are often used interchangeably, but they operate at different layers of payment infrastructure. A payment gateway is a technology layer that encrypts card data and securely transmits it to the acquiring bank. Merchant acquiring is a banking service that processes card transactions and settles funds into the merchant's account. A payment aggregator combines both layers and adds non-card payment methods — digital wallets, cryptocurrency, QR-code payments, and more — under a single contract.
| Parameter | Payment Gateway | Bank Acquiring |
|---|---|---|
| What it provides | Secure data transmission channel | Settlement account and fund crediting |
| Who provides it | Processing company or aggregator | Bank under acquiring agreement |
| Supported methods | Visa / Mastercard / local card schemes | Cards (sometimes instant transfers) |
| Onboarding speed | From 1 day (aggregator) | 5–10 business days or more |
| Typical fee | Depends on provider and volume | Depends on bank and MCC category |
In practice, most businesses choose an aggregator: one integration unlocks multiple banks and dozens of payment methods simultaneously. Tegro Money is one such platform, covering bank cards, instant bank transfers, digital wallets, and additional instruments through a unified API.
Common Payment Methods for Online Businesses
Here are the most widely used methods worth considering when launching online payments:
- Bank cards (Visa, Mastercard, local schemes) — cover the vast majority of online shoppers in most markets.
- Instant bank transfers / open banking — lower fees compared to card acquiring, growing adoption across Europe and CIS countries.
- Digital wallets — relevant for digital goods, subscriptions, and younger demographics who prefer not to enter card details each time.
- Cryptocurrency — increasingly relevant for international projects and platforms serving audiences without conventional bank accounts.
- Payouts to sellers and partners — critical for marketplace models. For example, Libermall relies on a dedicated payment layer to handle settlements between the platform and individual sellers.
How to Technically Connect Payment Acceptance
API Integration
The API approach is best suited for teams with development resources. You construct the payment creation request on your server, handle webhook notifications about transaction outcomes, and maintain full control over the checkout UX. The payment form lives directly inside your application with no redirects, which typically improves conversion.
Hosted Payment Page or Widget
For minimal integration time, a hosted page or embeddable widget requires just a few lines of code — or even a no-code setup. The customer is redirected to the provider's page, enters their card details there, and is returned to your store after completion. The payment provider handles PCI DSS compliance and fraud screening on their end.
A typical integration sequence looks like this:
- Register an account with the payment provider and complete business verification.
- Retrieve your API keys from the merchant dashboard.
- Configure a webhook endpoint on your server to receive payment status notifications.
- Test the full payment cycle in the sandbox environment: success, decline, and refund scenarios.
- Switch to live mode and run a real control transaction before opening to customers.
What to Look For in Payment Provider Reviews
"The most important factor in choosing a payment provider is not the headline fee rate — it is settlement reliability and support response time when something goes wrong."
When reading reviews and comparing options, pay attention to these specific dimensions:
- Payment conversion rate: what percentage of payment attempts complete successfully. A 2–5% difference in conversion has a direct and measurable impact on revenue.
- Settlement timing: how quickly funds reach your bank account. The industry standard is T+1 or T+2; some providers operate on longer cycles.
- Refund and dispute handling: how straightforward it is to initiate refunds via API or the dashboard, and how chargeback disputes are managed.
- API documentation quality: up-to-date reference docs, available SDKs, code examples in your language or framework.
- Transaction limits and restrictions: maximum single transaction amount, payout caps, and minimum volume requirements.
Choosing a payment provider is an infrastructure decision, not a commodity purchase. Test conversion in real conditions, read technical reviews written by developers who have actually integrated the system, compare contract terms carefully — and only then scale your traffic. The right setup pays for itself through higher checkout completion and fewer failed transactions over time.
