Use the new document in place of the original everywhere.
⚠️ Good to know
· If the attached file is the course system's receipt (not a full tax invoice), the system says so and offers a button to the "Request a tax invoice" menu.
· Invoices received before this system existed (document number equal to the order number) can be corrected too; the team reviews them case by case.
· Past 24 hours? Message LINE OA @pureyo and the team will consider it case by case.
C
3% withholding invoices (juristic persons only)
For organizations and companies that pay for the course and must withhold 3% tax on service fees. The tax invoice shows the full contract amount (withholding is not a discount), and applies to orders of 1,000 THB or more, as the law requires.
C1.You have not requested an invoice yet and already transferred with 3% withheld: use "Request a tax invoice" as in section A, but at the delivery step choose "e-Receipt with 3% withholding". The system accepts the request only when the transfer equals the full amount minus 3% of the pre-VAT base.
Example: a 3,210 THB course → 3% of the 3,000 base = 90 THB → transfer 3,120 THB. The tax ID must belong to a juristic person (starts with 0).
C2.You already received a normal invoice and want it converted to withholding: choose "Convert an invoice to 3% withholding" on the home screen, within 30 days of purchase.

5.Send the certificate file back through "Submit a withholding certificate" (section D). Once received, the company issues the replacement invoice and refunds the 3% to the account you gave, with a transfer slip by email.
Order matters: the company issues the replacement and refunds only after receiving the certificate.
⚠️ Good to know
· Orders below 1,000 THB carry no withholding duty under the law (Revenue Department Instruction Tor.Por. 4/2528, Clause 12/7); the system will ask you to use a normal invoice.
· The amount on the tax invoice does not change; it always shows the full contract amount, and the 3% appears on the certificate.
· Original invoices issued as several per-course invoices cannot be converted automatically; message LINE OA @pureyo.

Frequently asked questions
Can an e-Tax Invoice / e-Receipt be used for reimbursement?
Yes. It is a digitally signed electronic document filed with the Revenue Department as the law requires, and replaces paper in every case. A format-change notice for your organization's paperwork can be downloaded at the terms step.
I can't find my order number
Look in the order confirmation email from pureyoacademy.com: 8 digits starting with 0000 (e.g. 00001234). Or ask on LINE OA @pureyo.
Can I enter the PaySolution number?
No. The PaySolution reference / Order ID (9–10 digits, in the payment-result email or on the payment page) is a different number from the pureyoacademy.com order number; the system will not find the order and cannot issue the document. Use only the 8-digit number from the order confirmation email.
What happens if the amount I enter doesn't match your records?
The request is still saved and the team checks it before issuing. If you transferred today, the system matches the amount automatically after the nightly data sync; there is no need to resubmit.
I bought several courses in one order. Can I get separate invoices?
Yes. Tick "one tax invoice per course" at the order step; the system issues one invoice per course and sends them together in one email.
My organization withholds 3% tax. What do I do?
If you transferred with tax withheld and now want the invoice, use section C1 · if you already received a normal invoice and want to change it, use the conversion menu in section C2 (within 30 days of purchase). Either way, the certificate must reach the company before the final documents are issued.
Why isn't the amount on the withholding invoice 3% lower?
Because withholding is not a discount. The tax invoice must show the full contract value; the tax withheld appears on the certificate (50 ทวิ), which the company uses as a tax credit at year end.
Can tax be withheld on an order below 1,000 THB?
The law requires withholding when a contract payment is 1,000 THB or more (Revenue Department Instruction Tor.Por. 4/2528, Clause 12/7). Below that, the system suggests a normal invoice.
How long is a quotation valid?
30 days from the issue date. Once expired, request a new one through "Request a quotation" (section E); the system does not accept purchase orders that reference an expired quotation.
Can an individual send a PO for an invoice?
No. A quotation issued to an individual is for approval paperwork; after paying, request the tax invoice / receipt as in section A. The PO and invoice steps exist for juristic persons only.
How does the invoice show withholding tax?
The invoice shows the full contract amount (withholding is not a discount), with the 3% withheld on the pre-VAT base and the net payable stated. Your organization issues the withholding certificate (50 ทวิ) to the company.
