What documents do I need to send each month?

Sales tax invoices issued, purchase tax invoices received, bank statements for all accounts, payroll details if you have staff, and receipts for cash expenses. Scans or photos are acceptable; originals stay with you.

Which accounting software do you work on?

We work on the packages common in Thailand — Express, PEAK, Xero and FlowAccount among them. If you already use one, we continue on it; if not, we recommend based on your volume and reporting needs.

Who actually does the work?

Entries are made by TFAC-registered accountants whose continuing professional education hours are current, and the monthly output is reviewed before anything is filed. This matters because a filing error is the client's liability regardless of who typed it.

How is the monthly fee set?

By transaction volume, number of bank accounts, VAT status and payroll headcount — quoted in writing after we see one representative month of documents. We do not publish a fixed price list because volume decides the workload.

Monthly bookkeeping services in Thailand

Monthly bookkeeping is the foundation everything else sits on: the VAT return is only as good as the invoice set behind it, the annual audit is only as fast as the reconciliations are complete, and the tax return is only as safe as the ledger it is drawn from. Our monthly cycle delivers closed, reconciled books and filed returns before every statutory deadline, with an English summary for owners who do not read Thai worksheets.

What this service covers

Monthly journal entries and close

All transactions recorded to a chart of accounts built for your business, on Express, PEAK, Xero or FlowAccount, closed to a fixed calendar each month.

Bank and balance reconciliation

Every bank account, e-wallet and petty cash balance reconciled to source, so the cash figure in the reports is a fact and not an estimate.

Monthly tax filings

PP.30 VAT, PP.53 and PP.3 withholding, and social security contributions prepared from the ledger and filed before the deadlines.

English management summary

Revenue, cost, cash movement, receivables aging and unusual items summarised in one page the owner can act on.

How the engagement runs

1. Document intake
Invoices, receipts and bank statements arrive by an agreed date each month, by scan, e-mail or shared drive.
2. Recording and reconciliation
Entries are posted, accounts reconciled, and anything missing is chased while the month is still fresh.
3. Filings
The month's tax returns are prepared from the ledger and filed before the statutory deadlines.
4. Report
The month closes with the management summary and a note of anything that needs the owner's decision.

Deadlines, rates and filing formats change. Confirm current requirements with the Revenue Department, the Social Security Office and the Department of Business Development, or ask us to confirm them for your case before you rely on a date.

Common situations we are hired for

Replacing an in-house accountant

Outsourcing converts a fixed salary and the risk of a single resignation into a scoped monthly service with a team behind it.

Switching from another accounting office

We reconcile opening balances at the handover date before touching the current period, because inherited errors surface at audit otherwise.

A new company starting clean

Starting with a proper chart of accounts and document discipline from month one costs less than any cleanup later.

Books that fell behind

If several months are open, we close the backlog as a defined project, then continue on the normal monthly cycle.
