Three things a normal money app does not do

For people who want to know where their money goes, and people who file tax every year

Tax

Who it is for

Salaried workers with side jobs

You have both 40(1) and 40(2) income and are not sure which return to file or whether enough was withheld. WorkingBee puts it all in one place.

Freelancers

Issue documents to clients in the chat, chase unpaid invoices, and know from mid-year how much tax to set aside.

Frequently asked questions

Is WorkingBee free?

Yes. Sign in with your LINE account; there is no extra app to install.

Which income types can it calculate tax for?

All Thai personal income tax types 40(1)–(8), salary and freelance alike. It counts withholding tax from your 50 Tawi certificates and shows the allowances you can still use. Figures are estimates for planning; WorkingBee does not file your return for you.

Do I have to type entries in myself?

No. Send a photo of a transfer slip, a bill or a bank statement file to the chat and the amounts are read and recorded for you. Or type something short like "lunch 60".

Do you keep my slip images?

No. After reading the amount, date and reference number, the slip image is not saved, because slips contain other people’s names and account numbers.

Can I issue invoices or receipts to clients?

Yes. Create quotations, invoices and receipts as PDFs in the chat, with withholding tax and VAT. When a client pays, send the slip and it is matched to the invoice so you can issue the receipt.
