BUSINESS IN THAILAND / RESOURCE
These browser-based worksheets help you organise information before a review with your accountant. They are intentionally simple: use clear references, name the responsible person and attach the underlying evidence. They are not official returns, tax invoices, legal instruments or a substitute for a company’s accounting system.

How to use, save and print
Open the worksheet and complete its editable fields. Use the Print / Save as PDF button to retain a completed copy. To reuse the blank file offline, use your browser’s Save Page command. The worksheet does not upload your entries or save them automatically; refreshing or closing the page can discard them. Work from copies and store the final file in the company’s controlled records.
Use document references instead of embedding passports, passwords, bank credentials or unnecessary employee details. Editable fields are for working notes. Review the completed document before sharing it and remove information the recipient does not need.
Bank reconciliation: work from both records
Enter the statement balance and the ledger balance for the same account, date and currency. List timing differences separately from items that require a ledger correction. Record the amount, sign, source, date and follow-up for each difference. A difference should not be posted to a miscellaneous account merely to force the reconciliation to zero.
The worksheet is a manual review aid and does not calculate or post journal entries. Check arithmetic independently, attach the statement and ledger, and have the final reconciliation reviewed. Use separate sheets for separate accounts. See bookkeeping and reconciliation for the wider monthly process.
Cash flow: separate assumptions from confirmed amounts
Start with available cash and enter expected receipts and payments by week. Distinguish issued invoices from likely collection dates, and include payroll, rent, tax, debt service, capital spending and owner funding where relevant. Keep restricted cash or money held for another party separate from freely available funds.
Record the source and confidence of major assumptions. Revisit expected dates when customers pay late or a supplier schedule changes. The planner does not calculate a forecast automatically; it provides a structure for your reviewed figures. A forecast is a planning estimate, not a guarantee of future cash. The management reporting guide explains useful follow-up measures.
Invoice information: review before treating it as tax evidence
The checklist helps identify supplier and customer particulars, dates, numbering, description, amounts and tax information requiring review. It is not a ready-to-issue tax invoice and should not be given to a customer as one. The correct document and fields depend on the transaction, issuer’s status and applicable invoice rules.
Use the Revenue Department tax-invoice requirements and have the relevant particulars checked. An ordinary PDF is not automatically an approved e-Tax Invoice. The official e-Tax Invoice & e-Receipt portal explains that separate system.
Keep a review and version trail
- Record the company, period, preparer, reviewer and version date.
- Keep links or IDs connecting each line to source evidence.
- Flag unresolved items rather than concealing them in totals.
- Separate working versions from the approved copy.
- Agree which records go into the accounting system and who authorises adjustments.
- Update the worksheet when the business changes, without rewriting the history of a completed period.
Frequently asked questions
Do the worksheets calculate tax or submit forms?
No. They organise working information. They do not calculate tax, post journals or submit anything to an authority.
Is my entered information sent to Pimaccounting?
No. These standalone worksheets process no submission and make no network request for your entries. Save a completed copy locally before leaving the page.
Can I issue the invoice checklist to a customer?
No. It is a review aid, not an invoice. Use the correct invoice format and have its required particulars checked for your transaction.
Can the templates replace accounting software?
No. Use them to prepare and review evidence alongside the company’s accounting records, reconciliations and professional review.
