One system. The whole employee lifecycle.
The cost of stitching it together
Most Thai SMEs run recruitment in one tool, attendance in another, payroll in a spreadsheet, and reviews in a folder nobody opens. The tools are fine. The seams are not.
01
The same person, entered four times
A new hire is keyed into the ATS, the time clock, the payroll sheet and the org chart. Each copy drifts from the others.
02
Numbers that do not reconcile
Overtime approved in one system, paid from another. Nobody can say which is right without checking by hand.
03
Nothing to show an auditor
When the Labour Inspector or a PDPA request arrives, the evidence is scattered across tools and inboxes.

Time & attendance
Any phone can fake a GPS pin. Sentinel HR doesn't trust one.
Every clock-in passes four independent checks. A high-confidence spoof is blocked; a softer signal is flagged for HR before it reaches payroll.
- 1Site networkA site declares its office networks. A punch from anywhere else is refused, whatever the GPS says.
- 2IP and GPS must agreeThe server locates the request itself and flags a pin that disagrees with it.
- 3Impossible travelBangkok at 08:50 and Chiang Mai at 09:05 is not a commute. It is blocked.
- 4Rotating on-site codeA six-digit code only someone standing at the site can read.
Your policy per site: off, flag only, or block.

Thai compliance is not a plugin here

TMES started in 2011 as an IT services firm and grew into a platform company serving retail, financial services and enterprise clients across Southeast Asia.

Questions, answered
Still wondering? Talk to us
Is the live demo the real product?
Yes. It is the same Sentinel HR, running on sample data and read-only, so nothing you try is saved. Pick any of the seven roles to see what that person sees.
When can we sign up online?
Self-service sign-up for Sentinel HR Cloud is on its way. Book a guided demo and we will set up your workspace with you, or ask about Sentinel HR Dedicated today.
How do we pay?
By card, which renews automatically, or by PromptPay, invoiced each period. Prices are per active employee, in Thai baht, excluding 7% VAT.
Is our data separate from other companies?
Yes. Each workspace has its own set of tables and its own file space, encrypted at rest and backed up with point-in-time recovery, hosted on AWS in Singapore.
Can we start in the middle of the year?
Yes. Import employees, year-to-date leave balances and month-by-month payroll history so the first payroll withholds the right tax.
We need our own environment. Is that possible?
Yes — Sentinel HR Dedicated runs on infrastructure no other customer shares, on your own domain. Talk to us about Large Enterprise.
