Why compare against Zoho Invoice at all
When a Thai freelancer goes looking for invoicing software, Zoho Invoice shows up early for one reason that is hard to argue with: it is free. Not free-for-14-days. Free.
Zoho sold this product as a paid tool for 13 years before removing the price tag entirely. What you get is a mature product, not a stripped-down giveaway.
What Zoho Invoice genuinely does well
Credit where it is due — as international invoicing software, this is strong.
- One-off and recurring invoices, with customisable templates
- Automated payment reminders for overdue balances
- Time tracking that converts logged hours into billable amounts
- Expense capture, including billable expenses passed to clients
- A client portal where customers view documents, approve quotes and pay
- Multi-currency support, plus receivables, sales and expense reporting
- Integrations with Zoho CRM and Zoho Sign
If every client of yours is overseas, you bill in foreign currency, and Thai tax documents never enter the picture, this is very difficult to beat at zero cost.
The limits worth knowing up front
Free has edges, and Zoho publishes them.
- The current pricing page states up to 500 invoices per year, while older reviews still quote 1,000. Zoho notes the allowance is revised annually and visible under Settings then Usage Stats in your own account.
- Two users, three projects for time tracking, up to 1,000 customers, and 1 GB of storage.
- A Powered by Zoho Invoice line appears on documents.
- Support is email only — no phone, no chat.
- Accounts inactive for more than 180 days have their data deleted shortly after.
- Outgrowing the limits means moving to Zoho Books, which is paid.
These numbers move. Check the live pricing page before you commit.
The real difference is the word Thai
Zoho builds e-invoicing jurisdiction by jurisdiction. In India it operates as a GST Suvidha Provider connected to the IRP. In Saudi Arabia it submits to ZATCA's Fatoora platform. In Spain it handles VERI*FACTU. In other words, it invests where e-invoicing is strictly mandated.
Thailand is not on that list. There is no equivalent native connection to the Revenue Department's e-Tax Invoice system, and Zoho's withholding tax module is generic — it can calculate and record amounts withheld, but it does not produce a Thai 50 tawi withholding certificate or filing files for PND 3 and PND 53.
That is the gap Thai freelancers fall into every year. Not in the month they issue the invoice. In March.
Where MANA fits
MANA is not trying to be a global invoicing platform. It is built around the paperwork Thai freelancers actually have to produce.
- The document chain Thai clients expect — quotation, invoice, receipt, tax invoice — flowing one into the next without retyping
- 3 percent withholding calculated inside the document, and visibility over which jobs are still missing their 50 tawi certificate
- VAT and e-tax handling in a Thai context, including tax invoices
- PromptPay QR on the invoice, so payment and reconciliation line up
- Documents attached to projects and contacts, with a finance overview — not just a pile of PDFs sorted by date
- A Thai interface using the same vocabulary your client's accounting team and the Revenue Department use
Choosing today
Pick Zoho Invoice if almost all your clients are abroad, you bill in foreign currency, you are not VAT registered, you never issue a tax invoice, your document volume is modest, and your tooling budget is zero.
Pick MANA if Thai clients are the bulk of your income, withholding applies to most payments, your documents get reviewed by a client's accounting department, you issue tax invoices, or you are tired of chasing withholding certificates every January.
Or run both. Plenty of freelancers invoice overseas clients with one tool and handle Thai documents and tax with another. That is a perfectly reasonable setup, as long as everything consolidates in one place at year-end.
The honest difference here is not price. It is who receives your paperwork. If the destination is a Thai company's finance team and the Revenue Department, a tool that already understands those documents saves far more than any subscription gap.
