Monthly Bookkeeping and Accounting Records
Bookkeeping keeps your transaction records and monthly ledger up to date. Depending on the agreed scope, it can also include bank reconciliations, receivable and payable records, organisation of supporting documents, and information for tax filings and year-end accounts.
WMC provides monthly bookkeeping services for Thai and foreign-owned businesses operating in Thailand. We are based in Bangkok and work with companies throughout Thailand.
For ongoing tax oversight, see tax compliance support; return preparation and submission are covered separately through tax filing support. Where year-end work includes an independent audit, see statutory audit services.
Who this service is for
Thai and foreign-owned companies that need monthly bookkeeping: new companies, companies with owners overseas, and companies changing accountant or catching up on late records.
Bookkeeping for Foreign-Owned Companies in Thailand
Thai subsidiaries, companies with foreign shareholders and businesses managed by overseas teams may need accounting records maintained in accordance with Thai accounting requirements, and reporting information for directors and finance contacts abroad.
Where the scope includes reports for a finance team abroad, we prepare them in our standard format. If the team uses its own template, send us a blank copy and we will tell you what we can match. For broader accounting and tax support, see accounting and reporting.
Supporting Documents for Accurate Bookkeeping
Accurate bookkeeping needs supporting evidence for each transaction. Depending on your business, this may include invoices, receipts, bank statements, relevant contracts and payment records.
WMC flags missing or inconsistent information rather than treating an unsupported entry as complete.
If historical records are incomplete or overdue, a separate accounting cleanup review may be needed before regular monthly bookkeeping can proceed reliably.

FAQ
Frequently asked questions
What do bookkeeping services in Thailand include?
Bookkeeping normally covers transaction recording and maintenance of accounting records. Reconciliations, receivable and payable records, and organisation of supporting documents are included where agreed.
Does a Thai company need bookkeeping every month?
Usually, yes. Monthly filings such as VAT and withholding tax depend on that month's records. Which filings apply depends on the company's transactions, employees and VAT registration.
Can WMC provide bookkeeping for a foreign-owned company?
Yes. WMC provides monthly bookkeeping for foreign-owned companies, Thai subsidiaries and overseas-managed businesses operating in Thailand.
What documents are needed for monthly bookkeeping?
Common documents include invoices, receipts, bank statements, payment evidence, contracts where relevant and other records supporting the company's transactions.
What is the difference between bookkeeping and outsourced accounting?
Bookkeeping focuses on routine transaction records, while outsourced accounting may also include monthly closing, management reporting and broader finance-team coordination.
Can WMC take over bookkeeping from another accountant?
Yes. WMC can first review available records, opening balances, supporting documents and the prior process before agreeing the transition scope.
Does bookkeeping include tax filing?
Bookkeeping prepares the accounting information needed for compliance, while tax filing is a separate service that can be included when agreed as part of the engagement.
