How to vet a corporate services provider in Thailand in 2026: licences, references and red flags to check before signing

To vet a corporate services provider in Thailand, run three checks before you sign. First, identify the legal entity and the licensed professionals behind each service. Second, speak to references who can confirm that filings were made on time. Third, read the contract for red flags such as guaranteed approvals or offers of nominee shareholders.

A provider that handles your company registration, accounting, payroll and visas also holds your tax logins, company documents and employee data. A weak choice often shows up later as Revenue Department surcharges or a stalled work permit. Settlr Global, the operating arm of WOWS Global, runs company registration, accounting and tax, payroll, visas and employer of record (EOR) services from one Bangkok team. This checklist covers the questions buyers should ask any provider.

Key takeaways

This guide was prepared by Settlr Global's company and people operations team, led by Managing Director Gagan Ajmani, who brings 15+ years of regional experience across Southeast Asia.

What licences and registrations should a corporate services provider in Thailand hold?

Licensing is the first test. A corporate services provider in Thailand delivers several regulated activities at once, and each activity has its own regulator. A firm can be properly set up for one service and not for another.

According to the Department of Business Development's 2025 report on the Foreign Business Act[4], accounting and legal services are among the List Three businesses that foreigners generally cannot operate without permission. A foreign-majority provider should therefore explain the legal basis for each service it offers. A Foreign Business License is one possible basis, and DBD's 2025 report lists accounting and legal licenses among services to affiliated and intra-group entities[4]. Check that the legal basis covers every service listed in your contract.

Ask for the relevant names and licence details in writing before you receive the engagement letter. Then verify them yourself.

How do you check the provider's own company and the people doing the work?

Licences only mean something once they are tied to the entity that signs your contract and the people who will actually handle your filings. Check the provider's documents first and its claims second.

If a provider hesitates on Step 2 or Step 4, pause the signing. For comparison, Settlr Global's accounting and tax page sets out its own onboarding steps, which include a filing status check with the Revenue Department.

What should references from existing clients confirm?

Once the paperwork checks out, references show whether the provider meets deadlines in practice. Ask each reference questions that can be answered with yes, no or a date:

Ask for one reference at a similar stage to your business and one former client. A former client's account of the handover is often revealing. You can also check the filing dates that references mention against the Thailand Tax Calendar 2026.

Which red flags should stop you signing?

Document checks and reference calls tend to surface the same small set of warning signs. Each one points to a specific legal or operational risk.

If a provider will not fix a red flag in the contract itself, compare other providers. A clause-by-clause review through a legal advisory service can catch these issues before you sign.

How should you vet an employer of record in Thailand?

An employer of record in Thailand needs one extra layer of checks. The EOR becomes the legal employer of your staff, so any of the red flags above would affect your team directly. Before the first hire, confirm the following:

Settlr Global, for example, offers EOR from one employee. Fees start from THB 8,999 per employee per month for a local hire and THB 10,999 for an expat hire, and the first hire typically takes about two days. Plan details are on the employer of record page.

Founders who are scouting Thailand on a Destination Thailand Visa should note that the DTV does not permit holding employment with a Thai employer, as it is designed for remote workers and digital nomads. The DTV guide sets out the current requirements. Before the first hire, ask the EOR for a sample contract and a redacted payslip.

Frequently asked questions

Is there a single licence for corporate services in Thailand?

No official single licence was found. Bookkeeping, audit and court work each have their own rules, while tax filing and immigration work are made to separate authorities[1]. A foreign-majority firm generally needs permission under the Foreign Business Act to provide accounting or legal services.

How can I check that a Thai provider is registered?

Search for the provider's registration number in the DBD's online company database. Confirm that the company is active and that its directors and filed financial statements match what the provider has told you[8].

Can a provider guarantee my work permit or DTV approval?

No. Thai authorities make the final decision on every application. A provider can prepare a complete file, and the Thailand Visa Matcher gives an indicative starting point. For hands-on support, see the visa and work permit services page.

What does the US Treaty of Amity change when I vet a provider?

Qualifying American businesses can hold full ownership of a Thai company and operate largely on the same basis as Thai nationals, except in the six activities the Treaty reserves, which include communications, transport and deposit banking[9]. Ask the provider to explain how it handles the Amity certification route.

Is using one provider for everything riskier?

A single provider holds every credential, so the checks in this guide matter more. In return, one team owns every deadline, which removes handoffs between separate firms. The business operations model shows how this works in practice.
