Otty's short answer
FlowAccount is cheaper at the start: Standard is ฿165 per month and already includes e-Tax invoice and bank statement import. PEAK costs more, from ฿500 per month for Basic, and puts e-Tax invoice in Pro Plus at ฿1,200 per month, but includes more users, ledgers and payroll in each tier. Pick FlowAccount for a lean business. Pick PEAK for fuller books and controls.

Which one fits you
OCTIS · Hong Kong company + OCTIS global plan
Choose OCTIS if your team is spread out and you want accounting, CRM, automation and AI agents in one workspace instead of separate tools.
FlowAccount
Choose FlowAccount if you are a freelancer or small shop, want e-Tax invoice at the lowest monthly price and are happy to add payroll only when you need it.
PEAK
Choose PEAK if you need a proper ledger and statements, more users, payroll inside the plan, or approvals and purchasing controls, and can pay from ฿500 per month.
What the table does not show
What each plan costs
FlowAccount lists Standard at ฿165 per month, Pro at ฿249 and Pro Business at ฿457, with yearly prices of ฿1,990, ฿2,990 and ฿5,490. PEAK's home page lists e-Document at ฿208 per month on a yearly deal, Basic at ฿500, Pro at ฿900, Pro Plus at ฿1,200 and Premium at ฿3,500. PEAK does not state its billing period or VAT basis for each tier, so confirm both. The two ladders are not like for like. PEAK counts users, payment channels and warehouses by tier, so compare the features you need, not the first price you see.
e-Tax invoice and bank matching
FlowAccount lists e-Tax invoice with time stamp from the Standard plan, and bank statement import for KBank and TTB with reconciliation. PEAK lists e-Tax Invoice and e-Receipt in Pro Plus and bank reconciliation from Pro. If you plan to issue e-Tax invoices, FlowAccount reaches that feature at a lower plan. If you want automatic documents created from bank lines, PEAK lists that in Pro Plus. Check your bank before you buy, because bank coverage differs.
Payroll and add-ons
FlowAccount sells payroll as a separate ฿249 per month or ฿2,990 per year add-on, and leave management at the same price. PEAK includes PEAK Payroll in its plans, with a cap of 5 employees in e-Document, 10 in Basic, 20 in Pro and none in Pro Plus. If payroll is a core need and you have more than a handful of staff, add it up. A cheaper base plan with two add-ons can cost more than one mid plan.
Where OCTIS fits
OCTIS does not provide Thai bookkeeping or file Thai tax. If your Malaysian or Hong Kong company has a Thai subsidiary on FlowAccount or PEAK, OCTIS keeps the home company's books and brings the Thai statements into your group view. For your home accounting bill, OCTIS offers 10–30% off your current bill.
