Features
Everything a Thai company's books need
From the first quotation to the year-end close, every document posts its own journal entry and tax record.
Sales to cash
Quotation, sales order, delivery note, tax invoice, billing note and receipt — with partial deliveries, deposits and credit or debit notes that keep VAT right.
Purchasing & payments
Requisitions, purchase orders and goods receipts flow into supplier invoices and payments that withhold tax and print the 50 ทวิ certificate.
VAT done right
Output and input VAT reports with the PP.30 summary, VAT on services recognised when paid, non-creditable VAT and claims in a later month.
Withholding tax
Several income types per payment, PND.3, PND.53 and PND.54 reports, RD Prep import files, e-WHT payments and certificates from customers tracked.
Inventory
Moving average or FIFO costing per group, warehouses and transfers, stock counts, and back-dated documents that re-cost what came after.
Cash, bank & cheques
Cheques received and issued with clearing, deposit slips, transfers, and bank reconciliation from your statement file.
Foreign currency
Invoice and pay in USD, EUR or any currency at the day's buying or selling rate, with realized exchange gains and losses and period-end revaluation.
Reports that reconcile
Trial balance, general ledger, profit and loss, balance sheet, AR/AP aging and stock valuation — each checked against its control account, exportable to Excel.
Many companies, one sign-in
An organization keeps the books of several companies. Invite staff, owners or your accounting firm and choose what each person may open.
Familiar from day one
Works the way Thai accountants already work
If you have used Express, you already know where everything is.
The same numbered menus
Documents carry the numbers you expect — IV, RE, PS, JV with the Buddhist year and month — and dates show in the Buddhist Era.

Controls
Books you can hand to your auditor
Panya is built on double-entry rules that cannot be bypassed.
Balanced, always
The database itself refuses an entry whose debits and credits differ.
Posted means posted
A posted document can't be edited; cancelling it posts a reversing entry and keeps both on record.
Closed periods stay closed
Close a month or a year and nothing can be posted into it.
A complete audit trail
Who created, posted, cancelled or changed what, and when — for every company.
Your data, separated
Every organization's data is isolated by row-level security inside the database, not just by the application.
Your data, portable
Integrity checks reconcile the ledgers on demand, and a full export can be restored.
Pricing

Every module, every tax form, unlimited companies, users and transactions. Pay only for extra file storage and the AI you use.

High volume or special workloads
| Suggest accounts for a document | From 1 credit |
| Answer a question or summarize | From 4 credits |
| Read an invoice or receipt | From 3 credits a page |
| Larger analysis | By usage, estimate shown first |
A free request covers up to 10 credits of work. Larger requests are charged by use, never more than the estimate shown first.
Pay only for what you use: no monthly AI fee, and credits never expire. Larger tasks show their estimated cost before they run, and you can see your usage and balance any time.
AI output is always a draft: you review it and post it through the normal workflow. AI never bypasses validation, permissions or the audit trail.

FAQ
Questions, answered
What is Panya?+
Panya is online accounting software for Thai SMEs and the accounting firms that serve them. It runs in the browser and covers sales, purchasing, VAT and PP.30, withholding tax with PND.3/53/54 and 50 ทวิ certificates, inventory, cash and bank, and financial statements. Accounting on Panya Cloud is free forever; you pay only for extra file storage and AI credits, or run Panya On-premises on your own servers by quotation.
Do I need to install anything?+
No. Panya runs in your browser on Windows, Mac or a tablet. Your data is kept on the server, so you and your accountant see the same books.
Can my accountant or accounting firm work in Panya?+
Yes. Invite them to your organization and choose which companies they may open and what they may do. An accounting firm can keep many clients' companies under one sign-in.
Is Panya really free?+
Yes. Accounting is free forever on Panya Cloud, with every module and no limit on companies, users or transactions. You pay only if you need more than 100 MB of file storage, or more AI than the 20 free requests a month.
What happens when my file storage is full?+
Only new attachments stop. You keep entering documents, posting and running reports, and nothing is deleted. Choose a larger storage plan or remove files to attach more.
Can I move from Express or another program?+
Yes, for free. Import the chart of accounts, trial balance, customers, suppliers, products, outstanding receivables and payables, and stock balances from the files Express exports (Excel or CSV) or any CSV, then check the migration report and carry on from your opening date.
Does Panya issue e-Tax invoices?+
Yes. Smaller businesses can send e-Tax Invoice by Email with the time-stamp service. Larger ones send ETDA-standard XML through an e-Tax service provider, which signs and files it.
Which tax returns does it prepare?+
The VAT reports with the PP.30 summary, withholding tax reports for PND.3, PND.53 and PND.54 with RD Prep files, 50 ทวิ certificates, and PP.36 for services bought from abroad.
How is AI charged?+
Each organization has 20 free AI requests a month. After that you buy prepaid credits (from ฿49) that never expire. Panya shows the estimated cost of larger tasks before they run, never charges twice for a retried request, and AI only ever prepares drafts for you to check.
Can I take my data with me?+
Always, and for free: export reports to Excel or CSV, or the whole organization as one file that can be restored.
