If you're a Thai freelancer shopping for something to issue quotations, invoices and receipts, FlowAccount is the name you'll hit first. It's Thai-built cloud accounting software, it's been around for years, and it has a large base of SME and bookkeeping-firm users.
Here's an honest comparison of where the two differ — without pretending the other one is bad, because it isn't.
What FlowAccount does well
Worth stating plainly: FlowAccount is strong at what it set out to be — full accounting for Thai businesses.
- Complete Thai tax coverage. VAT, withholding tax, e-Withholding Tax, and electronic tax invoices — both e-Tax Invoice by Time Stamp (formerly by Email) and the full e-Tax Invoice & e-Receipt standard.
- Real accountant collaboration. Pro and above support unlimited users, so your bookkeeping firm works in the same data and can close the books for DBD filing.
- Payroll. A separately-priced module that calculates social security and employee withholding, with files ready for online submission.
- Marketplace selling. Pro Business connects Shopee, Lazada and TikTok Shop, and includes Open API access.
- Accessible pricing. A free tier, then roughly THB 165/month (THB 1,990/year), Pro at THB 249/month (THB 2,990/year), Pro Business at THB 457/month (THB 5,490/year), with a 30-day full-feature trial.
If you carry inventory, employ staff, are VAT-registered, or work with an outside accountant, FlowAccount is the better answer. Use it.
Where MANA is different
The difference isn't a feature count. It's the unit of work the system understands.
Accounting software sees the world as documents and ledger entries: invoices, receipts, income, expenses, closing the books.
MANA sees the world as one job for one client. The job starts as a conversation, becomes a quotation, gets agreed, runs in stages, takes a deposit, ships, gets invoiced, gets chased, gets paid, gets a receipt — and only then do you know what it actually earned. That entire chain lives on one screen, attached to one project.
What follows from that:
- Projects and paperwork are the same object. Open a project and you see what you quoted, which milestones you've billed, and what's still outstanding. No scrolling a global document list.
- Chasing payment is a feature, not homework. Overdue invoices surface on their own. You send a public document link the client opens and pays via PromptPay without creating an account, and the attached slip books the income.
- It looks forward, not just backward. Accounting answers what happened last month. MANA answers whether next month's money will be enough, based on work in hand and milestones not yet billed — the question a one-person business asks more often.
- An AI assistant. Type "who hasn't paid this month" and have it draft the reminder email, instead of clicking through menus.
MANA's limits, stated up front
To be complete about it: MANA is not a double-entry accounting system. It isn't designed to produce financial statements for DBD filing. There's no employee payroll module, no inventory or warehouse management, and no marketplace sales sync.
If you've incorporated, hired staff, or sell physical products at volume, what you need is accounting software — not a freelance workspace.
The one question that decides it
Where does most of your time actually go — bookkeeping, or getting the job finished and the money collected?
If it's bookkeeping, monthly VAT filings, closing the books, running payroll — use FlowAccount.
If it's chasing the client who hasn't paid, not remembering whether this project was fully billed, not knowing whether next month covers rent, and needing Thai-format quotations, invoices and receipts with a PromptPay QR that look professional — MANA was built for exactly that day.
And it isn't always either/or. Plenty of freelancers run MANA as their daily workspace and hand a summary to a bookkeeper who works in their own accounting system. The combined cost still comes in under buying a top-tier plan for features you never open.
