Otty's short answer
FlowAccount Payroll is a ฿249 per month add-on, or ฿2,990 per year, with no employee cap stated on its page, social security files, PND1 and 50 Tawi output and bank transfer files for four banks. PEAK includes payroll in its plans but caps staff at 5, 10 or 20 until Pro Plus, which is ฿1,200 per month. FlowAccount suits payroll-only buyers. PEAK suits businesses that also want its accounting.

What the table does not show
What FlowAccount Payroll covers
FlowAccount lists employee records, leave management, salary slips by email, social security contribution calculation with a downloadable file for online filing, withholding tax calculation, PND1 and PND1ก filing files, and a 50 Tawi year-end summary. It also produces bank transfer files for SCB, KBank, Krungsri and TTB. It costs ฿249 per month or ฿2,990 per year, with no employee cap stated, and it works with any FlowAccount package. The page ties the full payroll feature list to Pro Business, so confirm which plan you need.
What PEAK Payroll covers
PEAK's home page lists PEAK Payroll inside its plans with employee caps of 5 in e-Document, 10 in Basic, 20 in Pro and unlimited in Pro Plus. It does not detail payroll features such as social security files or PND1 on that page, so ask PEAK for a feature list before you buy. Pro Plus is ฿1,200 per month and Premium, which adds bank transfer file generation, is ฿3,500 per month.
How to decide
Count staff and decide whether you also need accounting. With 30 staff and no other need, FlowAccount at ฿249 per month is the lower published cost. With 10 staff and a wish to keep invoices, books and payroll in one tool, PEAK Basic at ฿500 per month may cover both. Run one real payroll month in each trial and have your accountant check the social security and withholding outputs.
Where OCTIS fits
OCTIS does not sell Thai payroll or file Thai tax. If your Malaysian or Hong Kong company hires staff in Thailand, the local payroll tool handles social security and withholding, while OCTIS keeps the home company's books and brings the Thai payroll cost into your group view. For your home accounting bill, OCTIS offers 10–30% off your current bill.
