The Challenge
บริษัทแม่ที่สิงคโปร์ต้องการตั้ง R&D Hub ที่กรุงเทพ ขอ BOI หมวด 5.7 (Digital Services) เพื่อถือหุ้นต่างชาติ 100% + ลดหย่อนภาษี 8 ปี แต่ไม่เข้าใจเงื่อนไข minimum investment และ skilled labor ratio
This case required tight coordination between Thai authorities (district office, MFA, สิงคโปร์ embassy) and destination authorities. Any formatting error would cause rejection and restart of the entire chain.
Our Solution
Our attorneys and certified translators designed an end-to-end workflow:
1. วิเคราะห์โครงการให้เข้าหมวด 5.7 และเตรียม Business Plan ภาษาอังกฤษ 80 หน้า 2. จัดตั้งบริษัทไทย + จดทะเบียนภาษีมูลค่าเพิ่ม + เปิดบัญชี Corporate 3. ยื่นคำขอ BOI ผ่านระบบ e-Submission + ประสาน BOI One Start One Stop 4. ขอ Smart Visa S Category สำหรับ CEO + 3 Senior Engineers 5. ขออนุญาตทำงาน + Work Permit ผ่าน BOI Single Window
Every step is QA-reviewed by licensed Notary Public attorneys before MFA and embassy submission — bringing rework rate to 0%.

ได้บัตรส่งเสริม BOI ภายใน 58 วัน · ถือหุ้นต่างชาติ 100% · ลดหย่อนภาษี CIT 8 ปี · Smart Visa 4 ปี
Key metrics: Timeline 58 วัน · Tax Saving ฿24M/8y · Foreign Equity 100%

Detailed Day-by-Day Timeline
The key lesson behind this case is a cross-border business workflow with สิงคโปร์ needs a timeline planned on day one — not improvised as situations arise.
Days 1-3: We receive the originals from Mr. Tan and verify completeness against the สิงคโปร์ destination checklist. If anything is missing or expired, we issue requisition letters to the originating Thai authority (district office, Department of Provincial Administration, Civil Service Commission) the same day.
Days 4-8: Our certified translation team translates and lays out each page in the exact format the สิงคโปร์ authority requires. Every page is proofed by both a native-speaker translator and an attorney who understands the destination legal terminology.
Days 9-14: Submission to MFA (Ministry of Foreign Affairs) for legalisation / Apostille, depending on whether สิงคโปร์ is a Hague Apostille Convention party. We use our courier slot which is pre-booked, cutting wait time from 5-7 business days to 2-3.
Days 15-completion: Embassy of สิงคโปร์ legalisation (where required) + final QC + dispatch via EMS / Kerry / DHL per the client's preference, with a PDF mirror sent for the client's records.
How We Mitigate Risk
Across 500+ similar cases we have handled, the three most common reasons documents get rejected are using a notary signature not registered with the Lawyers Council of Thailand, sending original documents without a certified copy backup, skipping destination embassy legalisation entirely.
To prevent these, we use our internal tracking system that lets clients monitor document status in real time so every step passes through human-in-the-loop review, not pure automation. Clients don't need to travel to MFA themselves and don't have to gamble on rejection.
A second safety layer is our destination-format database, refreshed every quarter — including details most generalist firms miss: confirming the MFA stamp sits on the same page as the translator's signature, and that the freshness window of civil records (6 months) is measured from the date of filing in สิงคโปร์, not the date we began translating.
Finally, our 47-point QA checklist that an attorney walks through before every filing — this is what lets Thailand-based clients avoid flying to สิงคโปร์ to coordinate locally. We can complete the chain from Bangkok end-to-end.
Document Chain Used in This Case
For a business matter with สิงคโปร์, the actual document chain involves multiple instruments that must be authenticated in the correct order, or the package is rejected.
The correct sequence is: (1) issue the original from the Thai government authority → (2) certified translation by a translator with a Notary Public attorney's countersignature → (3) attorney attests the translator's signature → (4) MFA legalises the attorney's signature → (5) สิงคโปร์ embassy legalises MFA's signature → (6) destination authority receipt.
Services bundled in this case included BOI Application, Company Setup, Smart Visa, Work Permit, all delivered as a single package. The client did not have to run between agencies — saving an average of 10-14 business days versus DIY.
Cost Breakdown & Value
Total cost for this case (approx THB 15,000-25,000) breaks down as: (a) government fees — MFA + สิงคโปร์ embassy ≈ 30-40%, (b) certified translation 25-35%, (c) notary & attorney fee 15-20%, (d) courier + admin 10-15%.
Compared with DIY, clients save an average of 30-50 business hours and reduce the rejection risk to 0% because an attorney reviews before every filing.
Key quantitative results: 100% First-Pass-Yield in this case, NPS 9.7/10 post-delivery, and total kickoff-to-delivery of 58 วัน.
