POS & Payment Processing Registration in Thailand

POS & Payment Processing Registration with SiamConsult

In Thailand, the use of POS systems, QR code readers, and online payment solutions is strictly regulated by government authorities.

All businesses that accept card payments, bank transfers, or digital wallets are required to comply with the standards set by the Bank of Thailand and the Thai Revenue Department. These include system registration, merchant account compliance, VAT declaration, and data protection protocols.

Whether you run a small café, a boutique store, or a nationwide e-commerce platform, operating an unregistered POS or payment gateway can result in frozen bank accounts, fines, or audit triggers.

Thai regulations require you to report all transactions clearly and maintain accurate digital records that sync with your accounting and tax filings.

SiamConsult ensures your business is set up properly from the beginning. We help you register your POS system, apply for a merchant account, integrate secure payment gateways, and fulfill all legal and financial obligations—so your business runs smoothly and compliantly.

POS & Payment Processing Registration – Step-by-Step Guide with SiamConsult

1. First, We Assess Your Business Needs

Before anything else, we begin with a one-on-one consultation to understand the type of business you operate—whether it’s a retail store, restaurant, online shop, or service-based company.

We also consider your expected sales volume and preferred methods of payment acceptance.
This helps us tailor a plan that fits both your needs and Thai e-payment laws.

We’ll explain everything clearly—especially what’s required by the Bank of Thailand, so nothing gets missed.

2. We Check Your Company Registration & VAT Status

To register a POS or merchant account in Thailand, your company must first be established legally.

SiamConsult reviews your business registration with the Thai Limited Company Setup and confirms whether you are required to register for VAT.

If you are unsure about VAT, see our VAT Tax Services Guide.

This step is important because non-compliance can delay banking approval or tax registration.

3. Choosing a POS System That Works for You

Once your registration is complete, we help you select the right POS system, including both hardware and software.

Whether you’re selling in a physical shop, through an app, or via a website, SiamConsult coordinates with licensed Thai vendors to ensure the system is compliant and easy to use.

We can also assist with setting up your system’s cash register and teach you how to generate various reports.

We also make sure it supports Thai invoicing, tax recording, and data security laws. For accounting and bookkeeping support, visit our Accounting Services.

4. Applying for a Merchant Account

After selecting the system, we assist in preparing your merchant account application with your chosen Thai bank or payment provider.

We guide you through the full process—from document preparation to bank due diligence checks (KYC), compliance assessments, and risk profiling.

If you need help with business licensing, see Business License Services.

5. Integrating Secure Payment Gateways

Next, we assist in connecting your POS system or online store with secure Thai and international payment gateways (like credit card, PromptPay, QR, or e-wallets).

We test transactions together with you, verifying that everything runs smoothly and complies with banking standards. For e-commerce business support, refer to our E-Commerce License Guide.

6. Making Sure You’re Compliant

Thai e-payment laws include strict requirements for transaction logging and the protection of consumer data.

SiamConsult checks your setup to ensure everything is safe, transparent, and compliant with regulations from the Bank of Thailand and the Revenue Department.

For ongoing tax compliance, visit our VAT Tax Services page.

This helps avoid unexpected legal or financial issues down the road.

7. Supporting You Long-Term

Once your POS system is live, we don’t disappear.
SiamConsult provides ongoing support with accounting integration, payroll, tax reporting, and system upgrades, ensuring you always stay compliant and efficient.
