A quote for Thailand should turn a sales conversation into a usable commercial document. You need buyer details, seller details, quoted items, quantities, prices, currency, validity dates, and payment terms in one place. The buyer should be able to approve the offer without asking whether delivery, tax treatment, discounts, or project scope are included.
Use Thai baht for local quoting unless the buyer has agreed to another currency. Thailand's VAT tax-invoice rules require Thai language and Thai currency unless the Revenue Department approves otherwise, so a quote that will later become a VAT tax invoice should collect those details early. A clean quote also helps prevent mismatches between the accepted price and the final invoice.
Start with the document title, quote number, issue date, seller name and address, buyer name and address, and the contact person who can approve the work. Add line items with plain descriptions, quantities, unit prices, discounts, and totals. Put delivery timing, validity period, payment terms, and any acceptance instructions near the total so the buyer sees the commercial decision clearly.
A service quote can be simple: consulting setup, 10 hours, THB 2,500 per hour, THB 25,000 before VAT. Add a note that final invoicing follows the accepted scope and applicable VAT status. Payment terms are contractual in Thailand's VAT tax-invoice particulars, since the statutory list includes the issue date but does not list a payment due date or payment terms.
Thailand uses VAT on supplies of goods, services, and imports. A person or entity regularly supplying goods or services in Thailand is subject to VAT when annual turnover exceeds THB 1.8 million. The Revenue Department states the current general VAT rate is 7%, while the Revenue Code sets a 10% rate that may be reduced by Royal Decree.
A quote is where you prepare the information that later needs to be correct on a VAT tax invoice. A full Thai VAT tax invoice must show the words "tax invoice," issuer name, address, taxpayer identification number, buyer name and address, serial number, issue date, line-item description, quantity, value, and VAT amount separated from the value of the goods or services.
A one-off quote tool is enough when you need a clean PDF or shareable document for a single buyer, a fixed scope, and simple approval. It works well for freelancers, small agencies, and suppliers sending a price before work starts. The key is to leave with a quote that preserves line-item detail, THB totals, and the commercial terms the buyer accepted.
A managed workflow fits better when quotes come from billable time, project estimates, and changing client work. Everhour Reporting lets teams group and filter project data, use 45+ report columns, export reports, and schedule recurring email reports. That gives managers a clearer base for quote reviews, margin checks, and billing decisions before accepted work moves into invoicing.

A quote is a price offer before the buyer accepts the work. A Thai VAT tax invoice is issued by a VAT registrant at the time VAT liability occurs for a sale of goods or provision of services. The quote should prepare the pricing and buyer details, but the tax invoice has specific statutory fields and recordkeeping duties.
Use Thai baht for a Thailand quote unless the buyer and seller agree to another currency. Thai VAT tax-invoice particulars must be in Thai currency unless the VAT registrant has approval from the Director-General to use a foreign currency. Foreign-currency VAT tax bases must be converted to Thai baht under the applicable Revenue Department conversion rule.
A quote should make VAT treatment clear when the seller is VAT-registered or expects the quote to become a VAT tax invoice. A full Thai VAT tax invoice must clearly separate the VAT amount from the value of the goods or services. Showing the tax line early helps the buyer compare the accepted quote with the final invoice.
A quote is not the same statutory document as a VAT tax invoice, but collecting the issuer's taxpayer identification number keeps the later invoice process cleaner. The issuer's taxpayer identification number is a required Thai VAT tax-invoice field, and taxpayers or income payers generally must obtain and use a taxpayer identification number under Revenue Department rules.
The common mistake is treating the quote total as complete while leaving tax status, currency, and line-item detail unclear. The final VAT tax invoice must show specific particulars, including buyer details, serial number, issue date, goods or services, value, and separated VAT amount. Missing detail forces manual corrections after the buyer has already approved the price.
