When people leave, your books shouldn't — accounting outsourcing for Thailand's high turnover
In Thailand, accounting staff change jobs often — a new hire may be gone within a year or two. Here's how outsourcing removes handover gaps, key-person dependency and work stoppages, with an honest total-cost comparison against hiring.
Design your accounting for a workforce that moves
One of the first realities Japanese companies meet when running a Thai subsidiary is how often staff change jobs. When wages are rising, switching employers every year or two for a better offer is common — and accounting professionals are no exception.
Hiring itself isn't the hard part. The real question is what happens after someone leaves.
The hidden risk of depending on one person
The smaller the subsidiary, the more tempting it is to leave accounting entirely to one person. That's efficient in calm times, but the moment they resign, the cost surfaces in several ways:
- Key-person dependency: posting rules, client-by-client treatment, and historical context all live only in their head — and leave with them.
- Incomplete handover: a full handover in the two-to-four weeks before departure is hard, and disastrous if it overlaps the monthly or tax close.
- Work stoppage: hiring and ramping up a replacement takes two to three months. Bookkeeping stalls, and VAT / withholding deadlines are at risk.
- Control gap: one person holding receipts, payments and bookkeeping is also fertile ground for fraud.
Seen from Japan HQ, this usually shows up as: "we left it to the local team, and suddenly the numbers stopped coming."
Put the total cost of "hiring" vs "outsourcing" side by side
The cost of hiring doesn't end at the monthly salary. In practice it stacks up:
- Salary, social security, benefits, bonus
- Recruiting cost (agency fees, interview time)
- Training and ramp-up (months before they're fully productive)
- Fixed costs — accounting software, desk, PC
- And all of it repeats every time someone resigns
Outsourcing consolidates these costs and risks into a monthly service fee. We absorb the burden of recruiting, training and turnover, and your workflow doesn't stop when an individual changes.
Three reasons outsourcing stays stable over the long run
1. A team handles your work, not an individual
Because it doesn't depend on one person, work is handed over within the team when someone is out or leaves. Key-person dependency stops being structural.
2. Process and knowledge accumulate in the firm
Posting rules, the monthly-close procedure and client-specific treatment are standardized as documentation and stay with us. Your "accounting memory" doesn't vanish when an employee resigns.
3. Expertise and updates never lapse
Continuously keeping up with changes to Thai tax law, accounting standards (TFRS) and e-Invoice is a heavy load for a single person. A team can keep pace with the latest practice.
You don't have to outsource everything — the hybrid answer
There is, of course, value in having accounting staff on site. The key is to separate the functions best kept in-house (on-the-ground data entry, approvals, cash handling) from those more stable when outsourced (bookkeeping, monthly close, tax filing, HQ reporting).
We design for either a full hand-off or a partial complement — whatever fits your setup.
