What Does a Bookkeeper Do for a Small Business?

Recording transactions

The foundation is capturing every business transaction and coding it correctly: sales, purchases, wages, loan repayments, owner drawings and contributions, and transfers between accounts.

Coding matters more than it appears. The account a transaction is allocated to drives your profit and loss, and the GST treatment applied drives your activity statement. Transactions with no GST, mixed supplies, and purchases that are partly private are the usual sources of error.

Reconciliations

Reconciling means proving your records against an independent source. A bookkeeper regularly reconciles:

• Business bank accounts against bank statements
• Credit cards and any finance facilities
• Merchant and payment platform settlements against recorded sales
• Loan and hire purchase accounts against lender statements
• Clearing and suspense accounts, so nothing is left unexplained

Accounts payable

On the payables side, a bookkeeper enters supplier bills, matches them to purchase orders or delivery documentation where that applies, tracks due dates and prepares payment runs for approval.

The practical benefit is visibility: an accurate aged payables report tells you what is owed and when, so payments can be scheduled around cash flow instead of paid reactively when a supplier calls.

Accounts receivable

On the receivables side, the work covers raising and sending invoices, allocating payments as they arrive, and maintaining the aged receivables report so overdue accounts are visible early.

Many bookkeepers also run a structured follow-up routine — reminders at agreed intervals, escalation to the owner at a defined point. For most small businesses this single routine has a bigger cash flow impact than anything else in the bookkeeping function.

Payroll integration

Where payroll is processed — in-house or outsourced — bookkeeping is where it lands in the accounts. Pay run journals need to post to the correct wage, PAYG withholding and superannuation accounts, and those balances need to be reconciled to what was actually reported and paid.

This reconciliation is what surfaces problems early: superannuation accrued but not paid, PAYG withholding that does not agree to activity statements, or wage figures that will not tie out at year end.

Record keeping

Australian businesses are required to keep records that explain their transactions and are able to be substantiated. In practice this means source documents — invoices, receipts, contracts, bank statements, payroll records — stored so they can be retrieved when needed.

Most cloud accounting systems attach documents directly to transactions, which is the tidiest approach. A bookkeeper maintaining this consistently is what makes a year-end or a review straightforward rather than a document hunt.

Management reporting support

Once records are accurate and reconciled, useful reporting becomes possible: a monthly profit and loss that can be trusted, a balance sheet that reflects reality, aged receivables and payables, and a view of cash position.

Bookkeepers typically prepare and circulate these reports. Interpreting them — margins, pricing, structure, tax planning — is generally where your accountant or adviser steps in.

BAS preparation and support

Bookkeeping produces the data that activity statements are built from: GST on sales and purchases, PAYG withholding, and any other reported obligations.

A point worth being clear about: in Australia, providing BAS services for a fee is restricted to registered BAS agents and registered tax agents. Many bookkeepers hold BAS agent registration; others prepare the underlying records and the BAS is lodged by a registered agent. Either way, the reconciliation work done through the quarter is what makes lodgement quick rather than a scramble.

How bookkeeping relates to accounting

The simplest distinction: bookkeeping maintains the record; accounting interprets it and meets the annual compliance obligations that sit on top.

Bookkeeping runs continuously through the year — weekly, fortnightly or monthly. Accounting work tends to be periodic: year-end financial statements, income tax returns, entity compliance, tax planning and structural advice. The accountant's work is faster, cheaper and more accurate when the bookkeeping underneath it is clean, which is why the two functions are best treated as one pipeline rather than two separate suppliers.
