Prosoft ibiz is a long-standing Thai cloud accounting system and a serious option for SMEs with stock, staff and an accounting firm. The question that keeps coming up is whether a solo freelancer should use it. Here is the comparison by the work you actually do each week, not by feature count.
What Prosoft ibiz does well
From the vendor's own site as of early August 2026, it covers most of a trading company's back office:
- Sales flow from quotation and sales order through deposits to tax invoices
- Purchasing with approval steps
- Inventory that adjusts automatically from sales and purchase documents
- Accounting, journals, cheque and bank management, petty cash
- Fixed assets with depreciation calculation
- CRM for customers and the sales pipeline
- OCR that reads data from photographed accounting documents
- Lazada and Shopee connectors pulling sales into the system
- e-Tax Invoice support, described as certified by the Revenue Department
- An ibiz Mobile app
If you carry stock, approve purchase orders, depreciate assets, or have an accountant closing statutory books, this is a tool built for exactly that. A freelancer about to incorporate and grow into a studio should keep it on the shortlist.
Where it does not fit a one-person business
Three things.
First, the pricing shape is built around seats. Packages are sold by user count, perpetual or annual, and cloud server rental is a separate line — the site lists starting points around 7,000 and 11,000 baht per year excluding VAT, with a 5 GB database limit per package. Software package prices are not published as a table; you contact sales. Those figures can change, so verify before deciding. For a freelancer trying to budget tonight without a sales call, that is friction at step one.
Second, the system speaks accountant. Chart of accounts, journals, posting. All correct and necessary for a registered company. But an individual freelancer does not close statutory accounts. What they need to know is how much came in this month, who has not paid, and how much to set aside for tax.
Third, most modules go unused. A writer, photographer, designer or developer has no stock, no purchase approvals, no departmental petty cash. A system that has everything is not easier — it is more menus to walk past every day.
MANA starts from a different problem
MANA does not try to be an accounting system. It is a workspace for one person, so it is organised around the day rather than the ledger.
- Contacts and projects live next to documents: one job holds its quotation, invoice, receipt and conversation history on a single page.
- Documents are Thai by default — quotation, invoice, receipt, tax invoice — with withholding tax handled on the document and a PromptPay QR on the invoice.
- Overdue tracking shows which invoices have passed their due date and when to follow up.
- The finance side is wallets, transactions and monthly budgets by category, with incoming payments matched to specific invoices.
- You can start alone tonight, with no chart of accounts to configure and no accountant needed to switch it on.
What MANA does not have deserves the same clarity: no journals or statutory financial statements, no inventory, no asset depreciation, no purchase approvals, no Lazada or Shopee connectors. If those are part of your daily work, MANA is the wrong pick.
How to choose
| Your situation | Better fit |
|---|---|
| Solo service work, a handful of documents a month | MANA |
| Need to see which jobs are unpaid and chase them | MANA |
| Selling physical stock that must be tracked | Prosoft ibiz |
| Incorporated, with an accounting firm closing your books | Prosoft ibiz |
| Selling mainly on Lazada or Shopee | Prosoft ibiz |
| A team that needs role-based access | Prosoft ibiz |
| Want to start using it tonight without a sales call | MANA |
The single question that settles it
Ask what eats the most hours in a typical month. If the answer is closing books correctly and managing inventory, take a full accounting system like Prosoft ibiz and stop looking for a shortcut. If the answer is figuring out who has not paid, retyping the same documents, and not knowing what is left this month, your problem is not bookkeeping — and a smaller tool gets you there faster.
The two are not mutually exclusive. Plenty of freelancers run their week in MANA and hand a monthly summary to an accounting firm that already runs its own system.
