How to Set Up Payment Acceptance — Where to Start and What to Choose
#crypto-acquiring
Launching sales comes down to one simple question — how to receive money from clients. Card transfers, acquiring, payment aggregators, cryptocurrency — there are many options, and each comes with its own terms, fees, and limitations. The wrong choice costs money and frustration. Let's break down how to set up payment acceptance from scratch, what methods exist, and what will work for your specific business.
Where to Start Setting Up Payment Acceptance
Define the Business Format
The payment acceptance method depends on what you sell. Physical goods with delivery, digital products with instant access, services with post-payment, subscriptions with recurring charges — each format requires its own approach.
For one-time sales, simple tools are enough — payment links or card transfers. For an online store with a catalog, website integration is needed. For a subscription model — support for recurring payments.
Define the primary scenario. How does the client learn about the product? Where does payment happen — on the website, in a messenger, offline? Is automatic access after payment required? The answers will point you toward the right tools.
Define Legal Status
Different payment solutions work with different categories of sellers. Major acquiring services require a registered business and a business bank account. Payment aggregators often work with individuals and freelancers.
If you're just starting and don't want to register a company right away — choose services that accept individuals. If the business is already registered — the full spectrum of solutions is available.
Factor in the tax obligations of your jurisdiction. Most payment services provide transaction reports that simplify income tracking.
Understand Volume and Client Geography
Ten sales a month and a thousand are different challenges. With a small volume, manual transfer processing is manageable. As it grows, automation becomes necessary — otherwise payment processing will consume all your time.
Client geography affects the choice of payment methods. If all buyers are from one country — local solutions are sufficient. If the audience is international — tools without geographic restrictions are needed.
Assess your current volume and growth forecast. Choose a solution with room to grow so you don't have to switch services in six months.
Main Payment Acceptance Methods
Bank Transfers
Card transfers are the simplest start. The client sends money by card number or phone number. You receive funds instantly.
Fast payment systems operate in many countries and allow transferring money between banks with no fee or a minimal charge. All you need is the recipient's phone number.
The advantages are obvious — zero or minimal commission, instant crediting, nothing to set up. The downsides are also real — manual processing of each payment, no link to orders, difficulties tracking a high volume.
Suitable for starting out, testing demand, and working with a small number of clients.
Online Acquiring
Acquiring lets you accept bank card payments online. The client enters card details on the payment page, the bank verifies and processes the transaction, and money arrives in your account.
To connect, you usually need a registered business and a bank business account. The commission is 1.5–3.5% depending on turnover and business category. Money arrives in the account within 1–3 business days.
Acquiring gives a professional look and a familiar payment method for clients. It integrates with websites, supports refunds, and provides reporting.
Payment Aggregators
Aggregators combine several payment methods in one service. Cards, electronic wallets, bank transfers, sometimes cryptocurrency — the client chooses a convenient option on the payment page.
The main advantage is easy setup. One contract, one dashboard, many payment methods. Many aggregators work with individuals and freelancers without requiring business registration.
Payment links allow accepting payment without a website. Create a link in the dashboard, send it to the client via messenger or email. They follow it, pay, and you receive a notification.
Invoices are electronic bills with a payment button. You specify the amount and description and send it to the client. Convenient for services and working with legal entities.
Ready-made payment forms embed into a website without complex integration. Copy the code, paste it into the page — the form works.
Setting Up Payment Acceptance on a Website
Connecting a Payment Form
A payment form is the interface where the client enters payment details. It can open on a separate service page or be embedded directly into your website.
To embed a form, you typically need to add code to the checkout page. Most services provide ready-made widgets — copy the HTML code and paste it where needed.
API Integration
An API provides maximum flexibility. You have full control over the payment process — from order creation to result processing.
API integration requires a developer. They connect the payment gateway following the documentation, configure data transmission, and handle server responses.
Advantages include custom design, complex logic, and integration with internal systems. Suitable for large projects with non-standard requirements.
CMS Plugins
If the website runs on a popular CMS — WordPress, Shopify, OpenCart, or similar — ready-made plugins are the easier choice.
Our service provides ready-made plugins for most popular CMS platforms. You can find connection instructions for each CMS at the link. The list of supported platforms is shown in the image below.
The plugin is installed from the marketplace or uploaded manually. In the settings, enter the API keys from the payment service dashboard. Specify the parameters — currency, payment methods, and the successful payment page.
After setup, cryptocurrency or cards appear as a payment method at checkout. Integration takes 15–30 minutes without a developer.
Setting Up Payment Notifications
Notifications tell your website about the payment status. The client pays — the service sends a webhook to the specified URL. Your server receives the data and responds — updates the order status, sends an email, grants access.
Set up the notification URL in the payment service dashboard. On your side, create a script that receives and processes the data.
Verify the authenticity of notifications. Services sign requests with a secret key — this protects against forgery.
Testing Before Launch
Don't launch payment acceptance without testing. An integration error means lost orders and dissatisfied clients.
Most payment services provide a test mode. Transactions go through like real ones, but no money is charged. Check the entire path — from clicking "Pay" to receiving the notification.
If there's no test mode — run a real payment for a minimal amount. Make sure the order status updates, the notification arrives, and access is granted.
Ask someone outside to go through the payment process. A fresh pair of eyes will find non-obvious issues.
Accepting Cryptocurrency Payments
When Cryptocurrency Is Convenient
Cryptocurrency solves problems that traditional payments cannot handle.
International clients. A buyer from a country where your acquiring doesn't work can pay with crypto. One payment method for the entire world.
High fees for cross-border transactions. A bank transfer from abroad is expensive and takes days. Cryptocurrency — minutes and a fixed fee.
Chargebacks. If your business suffers from fraudulent refunds — crypto provides protection. Transactions are irreversible after confirmation.
Crypto enthusiast audience. Some clients prefer to pay with crypto on principle. Without this option, you lose them.
Acceptance Options
Direct wallet acceptance — create a wallet, publish the address. Simple, but requires manual processing of each payment.
Crypto processing — the service automates acceptance. Generates a unique address for each payment, tracks transactions, sends notifications. Heleket allows connecting crypto payments without complex setup — ready-made plugins, API, payment links. Support for Bitcoin, Ethereum, USDT and other cryptocurrencies on various networks. Commission from 0.4%. Learn more at heleket.com.
Advantages and Possible Limitations
Advantages — low fees (0.4–1% vs. 2–4% for bank transfers), instant international transfers, no chargebacks, access to a global audience.
Limitations — not all clients know how to pay with crypto, exchange rate volatility (solved by stablecoins), need for tracking for tax purposes.
Cryptocurrency doesn't replace traditional payment methods — it complements them. Add crypto as an option, and some clients will choose exactly that.

For starting with minimal costs — basic bank transfers are an option, but clients will find it inconvenient to pay, and you'll be limited to a local audience.
For an online store with a local audience — card acquiring or an aggregator. Clients are used to paying by card, and conversion is higher.
For international sales — crypto processing works as a primary or additional method. No geographic restrictions, lower fees than card acquiring, transfers in minutes.
For freelancers and specialists with foreign clients — cryptocurrency solves the cross-border payment problem. Heleket lets you accept USDT, Bitcoin, Ethereum without complex setup and with a commission from 0.4%.
To reduce commission costs — add crypto payments to existing methods. Some clients will choose crypto, and you'll save on each such transaction.
Conclusion
Setting up payment acceptance starts with analysis — what you sell, who you sell to, and at what volume. The choice of tools follows from that.
Bank transfers work for starting out and a small volume. Acquiring and aggregators are for scaling and a professional look. Cryptocurrency is for international clients and reducing fees.
Don't limit yourself to one method. The more payment options available, the fewer clients will drop off at checkout. Start with a basic set and add new methods as you grow.
