How to Buy an Existing Business in Thailand: A Buyer’s Checklist

Buying an existing business can provide an established location, equipment, staff and customer base, but only when the buyer understands exactly what is included and verifies the information before paying. This checklist applies to restaurants, bars, spas, schools, factories, retail operations, hospitality businesses and other operating businesses in Thailand.

1. Identify exactly what you are buying

First confirm the proposed transaction structure. You may be buying selected assets, taking over a lease and operation, or acquiring shares in the company that owns the business. These structures do not transfer the same rights or obligations. Prepare a written list of everything included, such as equipment, stock, deposits, contracts, intellectual property, licences and digital accounts.

2. Confirm that the seller has authority

If the seller is a company, review its current registration documents and confirm who is authorised to sign. If the seller is an individual, verify identity and obtain evidence that the person owns or controls the assets and contractual rights being offered. Company information and filed financial statements can be checked through the Department of Business Development, but official records should be reviewed together with the documents supplied by the seller.

3. Check whether you can legally operate the business

The buyer should confirm the permitted business activities, ownership structure, required licences and any conditions applying to the premises. Foreign buyers should obtain qualified advice on foreign-business restrictions, company structure, visas and work permission. Acquiring a business or company does not automatically guarantee that every activity, licence or work position can continue under the new ownership.

4. Verify revenue, expenses and profit

Do not rely only on a seller’s summary or advertised monthly profit. Ask for records that support sales and operating costs, such as management accounts, bank statements, tax filings, point-of-sale reports, delivery-platform statements, supplier invoices, payroll and utility bills. Compare the records across normal, strong and weak trading periods and separate one-time income from recurring business revenue.

5. Review the lease and speak with the landlord

For a rented location, check the remaining lease term, rent increases, deposit, renewal conditions, permitted use, renovation obligations and termination clauses. Confirm whether the lease can be assigned or whether the landlord must issue a new agreement. The buyer should obtain the landlord’s written agreement before treating the location or existing deposit as part of the purchase.

6. Check licences and approvals

Required approvals vary by business type and location. Review the name on each licence, its expiry date, the issuing authority and whether it can be transferred or must be reissued. Depending on the operation, this may include food, alcohol, factory, school, hotel, signage, building-use, health, environmental or other sector-specific permissions.

7. Inspect assets, stock and intellectual property

Create an inventory stating the condition, serial number and ownership of important equipment. Identify rented, financed or supplier-owned items that may not belong to the seller. Confirm how stock will be counted and valued on completion. For the business name, logo, website, telephone numbers, social accounts and customer-facing digital assets, verify ownership and record how access will be transferred. Trademark information can be checked through Thailand’s Department of Intellectual Property.

8. Review staff, contracts and outstanding obligations

Understand the number of employees, compensation, accrued benefits, work-permit arrangements and any disputes or unpaid amounts. Review important supplier, franchise, booking, delivery, finance and customer contracts to see whether they can continue after the transaction. A share purchase may leave historical liabilities inside the company, while an asset purchase requires careful agreement on which obligations, if any, the buyer accepts.

9. Inspect the premises and operating condition

Visit the business while it is operating where possible. Check equipment, utilities, fire-safety arrangements, maintenance, access, signage, customer flow and any promised renovation. For larger or specialised premises, use qualified technical professionals. Record the agreed condition and inventory close to completion so missing or damaged items can be identified.

10. Control the deposit and completion process

A deposit should be supported by a written agreement that identifies the parties, transaction structure, price, included assets, due-diligence conditions, completion date, refund conditions and consequences of default. Avoid paying the full amount before the required contracts, landlord approval, licences and transfer documents are ready. Use independent legal, tax and accounting advisers appropriate to the size and complexity of the transaction.

Practical buyer checklist

Before completion, confirm the seller’s identity and authority, business structure, financial evidence, lease rights, licences, asset inventory, stock value, staff obligations, contracts, debts, taxes, disputes, digital access and completion documents. Any material statement that affects the price should be supported by evidence or clearly written into the agreement.

Useful official checks

Buyers can use the DBD DataWarehouse+ to check registered business information and filed financial statements, the Department of Intellectual Property search service for intellectual-property records, and the Revenue Department for current tax information. Online checks are only part of due diligence and should not replace certified documents or professional advice.

Next step

Review current businesses for sale through Thailand Business & Property and ask for the available high-level information before arranging a detailed discussion. Confidential listings may require buyer credentials and a confidentiality agreement before the business identity or private records are released.
