Assumptions
- Korean entity + Japanese entity (or branch)
- Serving both markets simultaneously
- 5–20 person team
Three-layer structure
**Shared global**: Slack, Notion, HubSpot, GitHub, Zoom, Google Workspace, Claude Team **Korea-only**: Channel.io(KR), Stibee, Flex, Samjeomsam/tax accountant, Naver Ads **Japan-only**: Sansan, freee, SmartHR or freee HR, LINE Official, Yahoo! Ads
Core principles
1. HR and accounting fully separated per entity 2. CRM in a single HubSpot with tags + pipelines split 3. Customer support tools per market (Channel.io KR vs JP) 4. Automation centralized in n8n
Monthly cost (10 people)
- Slack/Notion/HubSpot/Google Workspace: $500–800/month
- Channel.io: $100–300/month
- Stibee + Benchmark: $30–50/month
- Korean tax accountant: KRW 150–250k/month
- Japanese tax accountant: ¥30–50k/month
- Sansan: ¥30–100k/month
- Flex + SmartHR: ¥100–300k/month (headcount-dependent)
~$2–3k/month total.
Pitfalls
- Mixing KR/JP leads in one CRM without tags: requires strict pipeline separation
- Trying one HR SaaS for both countries: legally impossible
- One tax accountant for both: you need local experts per country
Dual-market ops requires the three-layer structure.
