Everything a public-sector agency needs to know before adopting Claude, in one place — compliant procurement · Por Por 36 / reverse-VAT · PDPA Section 40 · data residency via AWS Bedrock APAC — delivered by a Tier-1 Ministry of Finance consultant that has built systems for Thai public sector for over 24 years.
Anthropic is a foreign vendor that charges USD by credit card and doesn't issue Thai-format documents — which conflicts with public procurement and tax systems. Our service is built to close these four gaps.
Quote in baht · issue PO · Thai tax invoice · accept withholding tax · aligned with the Public Procurement Act B.E. 2560 and the e-GP system
Buy direct and the agency must self-file Por Por 36 — buy through us and get a Thai tax invoice with no Por Por 36 filing, reducing finance/accounting load
Clear controller–processor roles · DPA + SCC built into Commercial Terms · Team/Enterprise/API not used to train models by default
Process data in AWS Bedrock APAC (Singapore) for data sovereignty + Zero Data Retention (ZDR) via signed addendum
Buying licenses directly from Anthropic with a USD credit card rarely fits the Public Procurement and Supplies Administration Act B.E. 2560 — there's no Thai PO, no tax invoice, and no withholding tax acceptance.
Supports specific-method / selection / e-bidding depending on your agency's budget threshold and regulations — we prepare documents to match
Convert USD list price → baht at the quote-date rate + VAT 7%, ready for your supplies team to process in e-GP
Receive your agency's PO · activate the license · deliver per terms · issue a correct Thai tax invoice / receipt
Accept WHT certificates · manage billing/renewals · liaise with Anthropic on your behalf for the contract's life
When paying for a digital service from a foreign vendor not VAT-registered in Thailand, the buyer must remit VAT 7% themselves (reverse-VAT) via form Por Por 36 within 7 days of the following month.
| Topic | Buy direct from Anthropic | Buy through Grand Linux |
|---|---|---|
| Document received | USD receipt, not a Thai tax invoice | ✓ Full Thai tax invoice |
| Por Por 36 / reverse-VAT | ✕ Agency must self-file monthly | ✓ Not required — we handle the Thai tax side |
| Use as input VAT | Next month (1-month lag) | ✓ Same month |
| Withholding tax (WHT) | ✕ Not accepted | ✓ Accepted |
| PO per supplies regulations | ✕ None | ✓ Issue PO + process in e-GP |
| Payment | USD credit card only | ✓ Transfer/invoice in baht per your billing cycle |
As a data controller, a government agency must have an agreement and security measures when delegating personal-data processing to others (PDPA Section 40) — Claude for organizations meets this.
Agency = controller · Anthropic = processor · DPA + Standard Contractual Clauses built into Commercial Terms, covering TH→US cross-border transfer under PDPA Sections 28/29
Team / Enterprise / API do not use customer data to train models by default · API retention is 7 days (down from 30 since Sep 14, 2025) · unlike Free/Pro/Max
Process via AWS Bedrock APAC (Singapore) to keep data in ASEAN + opt for Zero Data Retention via signed addendum for highly sensitive work
We're not a new AI reseller — we've built systems for Thai government agencies and state enterprises for over 24 years, and we know how supplies regulations, disbursement, and government compliance actually work.
