Terms of Service
Last updated: November 12, 2026
These terms set out the conditions and procedures for using Sawadee TAX (the "Service"), operated by the Sawadee TAX operator (the "Provider"), and the rights and obligations of the Provider and its users. They apply once you accept them on the sign-up screen. Please read Section 2 (What the Service is) and Section 14 (Limitation of liability) in particular.
1. Definitions
- "User": a person who has signed up for the Service
- "Company": a business (a set of books) that a User creates in the Service. The User who creates a Company is its "Owner"; the people the Owner invites are "Team Members" (with roles such as admin or staff).
- "Customer Data": photos, documents, books, staff and supplier details and anything else a User uploads or enters into the Service
- "Paid Plan": a paid subscription (monthly or yearly) as described on the pricing page
- "Business User": a User who uses the Service for business purposes / "Consumer User": a User who is protected as a consumer under the law of their own country
2. What the Service is — a tool that helps with your books
The Service is a software tool that helps you keep your books and prepare for tax. It is not tax, accounting or legal advice, and the Provider does not act as your tax adviser, accountant or lawyer.
Everything the AI reads, categories and accounts, automatic journal entries, tax, payroll and social security amounts, the figures in the VAT (ภ.พ.30), withholding tax, corporate income tax and personal income tax helpers, answers from the AI CFO and AI assistant, the results of reading letters and contracts, and tax dates and reminders are reference material to support your own decisions. AI and calculations can be wrong or out of date, so you must check them against the original documents before saving or filing.
The Service does not file or pay tax on your behalf. Whether and what to file and pay, meeting deadlines, any surcharges or penalties, and other legal and business decisions are the responsibility of you (and any accountant you appoint). Consult an accountant or tax professional when needed.
When the Thai Revenue Department or other authorities change their rules, it may take some time for the Service to reflect the change.
3. A service for business, and consumer protection
The Service is designed for businesses, and most Users are Business Users. These terms are written on the basis of a contract between businesses.
However, if you are a Consumer User, nothing in these terms limits the rights that the law of your country guarantees to consumers on a mandatory basis (for example Korea's Act on the Regulation of Terms and Conditions and Act on Consumer Protection in Electronic Commerce, Japan's Consumer Contract Act, and Thailand's Consumer Protection Act and Unfair Contract Terms Act B.E. 2540). Where these terms differ from that law, that law prevails.
4. Accounts and Companies
Only people aged 20 or over who use the Service for business purposes may sign up. You must give true information when you sign up.
The Owner manages the Company and its Team Members. The roles and permissions set by the Owner and admins, and anything done in the Service by the people they invite, are the responsibility of that Company. When a Team Member leaves the Company, the Owner or an admin must remove their access promptly.
You must keep your e-mail, password and quick sign-in devices secure, and must not lend or share them with anyone else. If you suspect someone else is using your account, change your password at once and tell the Provider. Losses caused by failure to look after your account, without fault on the Provider's part, are borne by you.
5. Free trial and plans
A new Company may try the Service free for 14 days. Sole proprietors and other businesses try the Premium plan; juristic companies (whose tax ID is a company ID, or whose books are set up as a company) try the Business plan. The Provider sets the trial plan and users cannot change it (AI readings and AI assistant questions within the trial allowance). No payment details are taken during the trial, and when it ends the Company moves to the Free plan automatically. Each business can have one trial. A company's trial books start on 1 January of the year the company signed up, and that start date can be changed in the books' settings.
The price and features of each plan, and limits such as the number of AI readings, AI assistant questions, branches and Team Members, are as shown on the pricing page. Once a limit is reached, that feature cannot be used until the next period or until you upgrade.
The free plan is provided free of charge. The Provider may change its content and limits after giving notice in advance.
6. Payment, automatic renewal, price changes and cancellation
Payments for Paid Plans are processed by Paddle (Paddle.com Market Ltd.) as the seller (Merchant of Record). Paddle's buyer terms also apply to payments, invoices, receipts and tax calculation, and any tax added to the displayed price is shown on the checkout screen.
Paid Plans renew automatically for the same period (monthly or yearly) until cancelled, and are charged to your registered payment method on the renewal date.
If we raise a price, we will tell you in the Service and by e-mail at least 30 days before your next payment date. The new price applies from the next renewal after that notice, and you may cancel before then if you do not accept it.
You may cancel at any time in Settings. After cancelling, you keep using the Service until the end of the period already paid for, and no further payments are taken. If a payment fails, the Provider will notify you and try again; if payment still cannot be collected, the Provider may move the Company to the free plan.
7. Refunds
If you ask within 14 days of a payment, we refund that payment in full, with no questions asked. This applies to both first payments and renewals. Details are set out in the Refund Policy.
8. Your obligations
- Enter accurate information in the Service, and check what the AI has read and the calculated results before saving or using them.
- Keep original documents such as receipts and tax invoices yourself for the period required by Thai law (the Revenue Code, the Accounting Act and others — usually at least 5 years). Photos uploaded to the Service are working copies and do not replace the legal requirement to keep originals.
- Use the Service lawfully, and make sure the Team Members you invite and the accountants you connect also follow these terms.
- Have the rights to the material you upload, and do not upload material that infringes the rights of others or is unlawful.
- When you upload personal data of other people, such as staff or suppliers, comply with personal data law, for example by informing them or obtaining their consent (see Section 4 of the Privacy Policy).
- We recommend that you regularly keep a separate copy of important data using the Service's download features.
9. Prohibited conduct
- Accessing another person's account or Company data without permission
- Creating forged or altered receipts or tax invoices, or using the Service for tax evasion, money laundering or other unlawful purposes
- Attacking the Service or its servers, or disrupting it by sending excessive automated requests
- Copying, reverse-engineering or reselling the Service, or selling access to it to others without the Provider's permission
- Creating multiple accounts or Companies to get around trials or limits
10. Customer Data
The rights to Customer Data belong to the User (the Company). You allow the Provider to store, process and transmit Customer Data to the extent needed to provide, support and protect the Service.
The Provider does not sell Customer Data or use it for advertising. It may use statistics from which no person or company can be identified to improve the Service.
You can download your Customer Data at any time, as Excel files and photo bundles, from Settings → My data.
When the Owner closes a Company, that Company's Customer Data is kept for 30 days and then permanently deleted. During that time it can be restored or downloaded. Copies left in backups are overwritten on the regular backup cycle, and records the law requires us to keep (such as payment records) are kept separately for the required period.
11. Third-party services
The Service connects to third-party services such as LINE, bank statement files, Loyverse (POS), the Thai Revenue Department's VAT registrant lookup, Bank of Thailand and European Central Bank exchange rates, and Paddle (payments). These services are run by their own companies, and those companies' terms apply.
The Provider is not responsible for problems caused by outages, changes, discontinuation or incorrect information of third-party services, unless the Provider is at fault. If a third-party service changes so that a connection can no longer be offered, the Provider may change or stop that feature.
12. Provision, changes and interruption of the Service
The Provider works to run the Service reliably, but unless agreed separately in writing, it does not guarantee any particular uptime or uninterrupted service. The Service may stop temporarily for maintenance, faults or problems with third-party services (servers, AI, LINE, payments and so on). Maintenance that can be foreseen will be announced in the Service or by e-mail.
The Provider may change features and screens to improve the Service. AI features and features marked "beta" may change in results and behaviour frequently. If a major feature of a Paid Plan is removed or substantially reduced, we will give at least 30 days' notice; Users who do not accept the change may cancel, and we will refund the remaining period's fees pro rata by day.
If the whole Service has to end, we will give at least 30 days' notice, let you download your Customer Data during that time, and refund the remaining period's fees pro rata by day.
13. Suspension and termination
The Provider may restrict use or close an account if a User fails to pay, breaches these terms (in particular Section 9), or is likely to harm the security of the Service or of other Users. In such cases we will tell you the reason in advance and give you an opportunity to put things right; only in urgent cases, such as a security threat, will we restrict use first and tell you afterwards.
You may cancel or close your Company at any time. If use is restricted or terminated for reasons not attributable to the Provider, fees already paid are refunded only as provided in the Refund Policy and by law.
14. Limitation of liability
The Provider takes the care needed to provide the Service. The limits in this section do not apply to loss caused by the Provider's intent or gross negligence, to death, personal injury or harm to health, or to any liability that the law does not allow to be limited; in those cases the Provider is liable in accordance with the law.
Only where loss is caused to a User by the Provider's ordinary (slight) negligence, the Provider will compensate direct and ordinary loss only, and its total liability will not exceed the amount the Company actually paid for the Service in the 12 months immediately before the event that caused the loss (1,000 baht if the Company was on the free plan or a trial).
Only in cases of the Provider's ordinary (slight) negligence, the Provider is not liable for the following loss:
- Loss of profit, revenue or business opportunity, and indirect, special or consequential loss
- Tax, surcharges, penalties and interest arising because a User or their accountant decided to file or pay without checking the figures in the Service (deciding and checking what is filed is the User's responsibility under Section 2)
- Loss caused by a User not keeping original documents or not keeping a separate downloaded copy of their data
- Loss caused by matters beyond the Provider's control, such as the third-party services in Section 11, telecommunications networks or natural disasters
If you are a Consumer User, the limits above apply only to the extent permitted by the law of your country (for example, under Japan's Consumer Contract Act, liability for the Provider's intent or gross negligence cannot be reduced or excluded, and the limits above apply only to ordinary negligence).
15. Your indemnity
If a third party makes a claim against the Provider because a User has breached the law or these terms (for example by uploading material they have no rights to or forged documents, or uploading other people's personal data without a lawful basis), the User will compensate the Provider's loss (including reasonable legal fees) to the extent the User is responsible. The Provider will tell the User promptly on becoming aware of such a claim and will cooperate so that the User can respond.
16. Changes to these terms
The Provider may change these terms without breaching applicable law, to the extent that the change is reasonable and consistent with the purpose of the contract.
When these terms change, we will announce the changes and their effective date on the Service's screens at least 7 days before they take effect. Changes that are unfavourable to Users or important will be announced at least 30 days in advance and also notified separately, for example by e-mail.
The notice will state that "if you do not object by the effective date, you will be treated as having agreed". If you do not object and continue to use the Service after the effective date, you will be treated as having agreed to the changed terms to the extent permitted by law. Where a change requires your consent, we will ask for it again in the Service.
If you do not agree to the changed terms, you may cancel before the effective date. If you cancel because of an unfavourable change, we will refund the remaining period's fees pro rata by day.
17. Notices and electronic consent
The Provider sends notices to the e-mail address you registered, in the Service, and via LINE (if connected). Notices to all Users may also be given by posting them on the Service's screens for at least 7 days.
You agree that consent given by ticking a box and pressing a button on screen, and electronic records, have the same effect as a written contract (under Thailand's Electronic Transactions Act and other laws). The Provider records the date of your consent and the version of the terms.
18. Governing law and jurisdiction
These terms are governed by the law of the country where the provider is registered. If a dispute arises, both parties will first try to resolve it in good faith.
If it cannot be resolved by discussion, disputes with Business Users will be subject to the exclusive jurisdiction, at first instance, of the court with jurisdiction over the Provider's place of business.
Consumer Users keep the protection of the mandatory rules of their own country, to the extent that law guarantees it, including the right to bring proceedings in, and to be sued in, the courts where they live.
19. Miscellaneous and contact
If any part of these terms is invalid or unenforceable, the remaining provisions stay in effect, and the invalid part will be read as the closest provision the law allows. The Provider's failure to exercise a right immediately does not mean it has waived that right.
These terms are provided in Korean, Japanese, Thai, English and Simplified Chinese. If the versions differ, the Korean version prevails; however, for Consumer Users, the interpretation more favourable to them applies.
