Documents Needed for Bookkeeping: A Monthly Checklist for Malaysian SMEs

What documents does a bookkeeper need every month?

Your bookkeeper needs two kinds of evidence for every transaction: proof that money moved, such as a bank or e-wallet statement, and the document that explains why, such as an invoice, bill, receipt or payslip. For a typical Malaysian SME, the monthly pack looks like this:

• Statements for every bank account, e-wallet and card or QR settlement account
• Sales invoices, cash bills, receipts and point-of-sale summaries, plus e-Invoice listings if you issue e-Invoices
• Supplier bills, credit notes and supplier statements
• Expense receipts, staff claims and petty cash vouchers
• Proof of the payments you made
• Payroll records and EPF, SOCSO, EIS and PCB payment receipts
• Loan and hire purchase statements
• Invoices for any equipment, vehicles or renovation bought
• SST returns, if you are registered
• New contracts and agreements
• Stock count sheets, if you hold stock

The bank statement is the backbone. Every line on it should end up matched to a document, and anything without one becomes a query. For the bigger picture of how these records turn into accounts, read our guide to bookkeeping basics for Malaysian SMEs.

Where do you get each document, and why does it matter?

Most of these documents already exist somewhere: in your online banking, a merchant portal, your email or an office drawer. This table shows where to find each one and what your bookkeeper uses it for.

Document	Where to get it	Why your bookkeeper needs it
Bank statements for every account, including foreign-currency and fixed deposit accounts	Online banking: the monthly PDF statement, plus a CSV download if offered	Every receipt and payment is reconciled against them
E-wallet, card-terminal and QR settlement reports	The provider's merchant portal or monthly statement	Show the gross sales, fees and refunds behind each net payout
Online platform payout statements	The seller or partner dashboard	Payouts arrive net of commissions and charges, which are recorded separately
Sales invoices, cash bills, receipts and POS daily summaries	Your billing system, invoice book or end-of-day POS report	Record your income and what customers owe
e-Invoice listings, if you issue e-Invoices	MyInvois Portal: documents issued and received for the month	Confirm the books agree with what IRBM has validated, including credit notes
Supplier bills, credit notes and statements of account	Supplier emails or post; monthly supplier statements	Record purchases and what you owe; statements reveal missing bills
Expense receipts, staff claims and petty cash vouchers	Paper and email receipts; approved claim forms	Support each expense and its tax deduction
Payment proofs	Transfer confirmations, cheque stubs	Link each payment to the bill it settles
Payroll summary, payslips, joiners and leavers	Your payroll records or HR	Record salaries, allowances and deductions
EPF, SOCSO, EIS and PCB payment receipts	KWSP i-Akaun, PERKESO ASSIST and LHDN payment records	Confirm statutory payments were made by the 15th and clear the payable accounts
Loan and hire purchase statements	Your bank or finance company	Split each instalment into interest and principal
Invoices for assets bought	The supplier; the hire purchase agreement	Recorded as assets and depreciated; needed for capital allowance claims
SST-02 returns and payment receipts, if registered	MySST	SST payable in the books must agree with each return
New contracts and agreements	Your own files	Explain deposits, recurring charges and commitments
Stock count sheets, if you hold stock	Your month-end or year-end count	Closing stock sets cost of sales and profit

Two items are easy to overlook. Settlement reports matter because a RM9,640 payout might really be RM10,000 of sales less RM360 of fees, and supplier statements quickly reveal a bill that never reached you. Both make the monthly bank reconciliation much faster.

If your business is exempt from e-Invoice, there are no e-Invoice listings to send; your normal invoices and receipts do the same job. See the RM3 million e-Invoice exemption to check where you stand.

What does a new bookkeeper need from you on day one?

When you start with a new bookkeeper, they also need a one-time set of documents to set up your books correctly and carry forward the right balances:

• SSM records: registration documents and a recent company information printout showing directors, shareholders and financial year end (sole proprietors: the business registration)
• Last financial statements, audited or unaudited, and the last tax computation from your tax agent
• Opening balances at the start date: a trial balance, or at least bank balances, amounts owed by customers and to suppliers, stock, loans and fixed assets
• Tax and registration numbers: your tax identification number (TIN), plus SST and employer EPF and SOCSO numbers if you have them
• A list of every account: bank, e-wallet, merchant, loan and hire purchase
• Fixed asset register, or the invoices for major assets still in use
• Current contracts: tenancy, loans, and major customer and supplier agreements
• Access and approvals: MyInvois access with the right user role if you issue e-Invoices, and who approves payments and answers queries

Opening balances matter most. If they do not tie to your last financial statements, every month that follows starts from the wrong place. If you are moving from another provider, our guide on switching accountant or bookkeeper lists what to request from them.

How should you organise and name your documents?

A simple, consistent system matters more than the tool you use. These habits work for a one-person shop and a growing company alike:

• One shared folder per month (for example "2026-09"), with the same sub-folders every time: Bank, Sales, Purchases, Expenses, Payroll, Statutory and Others.
• File names that sort themselves: date, type, party and amount, such as "2026-09-14_bill_tile-supplier_RM1250.pdf".
• Snap paper receipts the day you get them. Thermal receipts fade, so a photo taken today is the copy that survives.
• Add a one-line note to anything unusual: what it was, who it was for and why, such as "refundable deposit for new shoplot".
• Mark business items on personal statements. If the director paid a business cost personally, send the receipt and the statement page with the item highlighted. Better still, stop mixing; see separating business and personal accounts.
• Translate the key details. LHDN expects records to be kept in English or Bahasa Malaysia, so add a short note to receipts written in other languages.
• Keep everything for 7 years. Electronic copies are acceptable if they can be produced on request; see how long to keep business records.

Use one channel. Documents scattered across chat messages, personal email and a car glovebox make a month very hard to close.

When should documents reach your bookkeeper?

Agree a fixed date early in the following month, such as the 7th, and treat it like a bill due date. Several statutory deadlines depend on your documents arriving on time:

What depends on your documents	Deadline	Why early documents matter
EPF, SOCSO, EIS and PCB payments	By the 15th of the following month	Overtime, new staff and resignations must be known before payments are worked out
Consolidated e-Invoice, if you issue one	Within 7 calendar days after month end	The month's sales records must be complete first
SST-02 return, if registered	By the end of the month after each two-month taxable period	Sales and SST figures must be final
Entries in a company's accounting records	Within 60 days of the transaction being completed (Companies Act 2016, s245)	Late documents push you towards the legal limit
Monthly management report	Your own target, for example two weeks after month end	Decisions are made on current numbers, not old ones

A workable rhythm is bank and settlement statements on the 1st to 3rd, payroll changes by the 5th, and everything else by the 7th. Our month-end closing checklist shows what your bookkeeper does with them next, and the payroll guide covers the statutory contributions.

What happens if documents arrive late or go missing?

Late documents do not just delay a report; they make the numbers you rely on wrong in the meantime.

• Bank lines without documents sit in a suspense account, so profit and balances are unreliable.
• Payroll and statutory payments are worked out in a rush, or paid late.
• Expenses without evidence may not be accepted as tax deductions.
• Gaps pile up until year end, when the accountant, the tax agent and the Form C deadline (7 months after your financial year end) all arrive together.

Example: a Penang hardware trader sends documents on the 7th of every month, but RM18,400 of August supplier bills sit in a drawer until December. For four months, August profit looks RM18,400 higher than it really is, the bank reconciliation carries RM18,400 of payments with nothing to match them to, and the owner plans a year-end bonus on numbers that are not real. The fix is simple: each month, ask your main suppliers for a statement of account and tick off the bills you hold.

If a receipt is truly lost, see what to do about missing receipts. If you are several months behind, start with catching up a bookkeeping backlog.

Which extra documents apply to your type of business?

Some businesses need a few more items each month. Add these to your checklist if they apply:

• Trading and retail: delivery orders and goods received notes, supplier returns and rebate notes, and stock count sheets. See inventory accounting for SMEs.
• Food and beverage: POS end-of-day reports, delivery-platform payout statements, and wastage or stock-take records.
• Contractors: progress claims and certificates, retention sums, subcontractor bills and site petty cash.
• Importers and businesses with overseas suppliers: foreign-currency invoices, freight and customs documents and, if you are not exempt from e-Invoice, the self-billed e-Invoices you issue for foreign suppliers. See self-billed e-Invoices.
• Service businesses: signed quotations or contracts, deposits received and billing schedules for long jobs.
