Register your business on a payment gateway: how to do it in minutes

When a business decides to start charging its customers via card or digital payments, it must begin a registration process with a payment service provider. However, the challenge lies not only in the final result but in the entire process that the business must complete to start operating, whether with its virtual POS or its physical POS.

At PaynoPain, we have taken a step further to simplify this process by incorporating artificial intelligence into merchant onboarding. Below, we explain how businesses can register on our payment gateway quickly, easily, and securely thanks to this innovation.

Merchant onboarding: a challenge for payment providers

Registering a business on a payment gateway can be more complex than it seems. According to the 2026 World Payments Report by Capgemini, one of the leading global consulting and technology service providers, only 13% of banks claim to be ready to offer fast and simple onboarding processes.

This step is not always easy for businesses. Beyond the financial cost, the opportunity cost is highly relevant, in other words, the time it takes for payment providers to activate the solutions necessary for the business to start collecting payments.

Main challenges of the onboarding process

Why are so many banks unable to offer efficient onboarding?

• Lengthy and unintuitive administrative processes.
• Manual verification of business data.
• Lack of immediate support during registration.
• Delays in document validation.

All these factors cause many businesses to wait longer than desired to start accepting card or other payment methods.

How PaynoPain simplifies business registration

At PaynoPain, we have developed a WhatsApp registration assistant that guides businesses step by step through the platform registration process. With this tool, completing onboarding feels natural, as if an expert were assisting you at every step from your mobile, with clear instructions and avoiding documentation errors.

Moreover, this registration method can be especially easy for those not familiar with digital tools. With the WhatsApp assistant, anyone can complete registration without complications, step by step and from their mobile.

Thus, the WhatsApp assistant helps the user at all times to:

• Resolve doubts in real time.
• Validate business information and necessary registration documents.
• Ensure proper completion of registration, eliminating unnecessary steps.

With this tool, businesses can start accepting payments with their virtual POS or physical POS much faster than with traditional processes.

Benefits for businesses registering on PaynoPain’s payment gateway

AI-driven onboarding at PaynoPain offers clear benefits for businesses that need to start accepting physical and online payments immediately:

Rapid POS activation

The time required to launch your POS is shortened, allowing your business to start collecting payments sooner.

Reduced friction

Being a fully guided process, confusion and complex steps during registration are minimized. This enables faster onboarding with fewer incidents.

Regulatory compliance

AI integration facilitates the KYC (Know Your Customer) process, i.e., verification of business identity to comply with financial regulations. This ensures that businesses are correctly identified before activating payment solutions with the provider, guaranteeing a secure payment environment.

Improved user experience

The conversational experience makes customers feel more comfortable using a familiar channel such as WhatsApp. It can also be simpler than traditional registration processes, especially for those not accustomed to digital tools. This makes merchant onboarding more intuitive and efficient, resulting in a pleasant and hassle-free experience.

Best practices to accelerate merchant onboarding

Even though payment solution technology simplifies onboarding, businesses can also follow some recommendations to speed up registration:

Prepare required documentation

Before starting registration, gather all company data and required documents to facilitate the process.

Review data before submitting

Once documentation is prepared, verify the information entered. This helps avoid delays in validation and reduces the likelihood of repeating steps.

Avoid changes during registration

Modifying documents or business data mid-onboarding can slow down the process and introduce errors.

Assign a responsible contact

Many businesses experience delays because multiple people or departments are involved. Assigning a single person or department centralizes the process and avoids lost information or duplicate steps.

Clearly reflect business activity

Ensure that the information provided during registration accurately represents the business’s actual operations. Correctly describing the products or services offered makes validation by the payment provider faster.

Update your website

Keeping the website up to date also facilitates verification. A clear website with proper information about the business activity and purchase conditions helps the payment provider validate the business more quickly.

Maintain aligned information across all channels

Business data should match across all communication channels: website, email, social media, or any other medium used. This consistency avoids doubts during verification.
