Small Business Bookkeeping Checklist: Weekly, Monthly and Year-End Tasks

• Small Business

Good bookkeeping is not about doing everything at once. It is about building a steady rhythm so your records stay clean, your invoices get followed up, and your reports make sense when you need them.

This checklist is designed for small business owners who want a simple routine. Use it alongside your Chart of Accounts, bank reconciliations, and key reports like the Profit and Loss and balance sheet.

The best bookkeeping system is the one you can maintain. A simple weekly routine beats a perfect spreadsheet you only open twice a year.

Weekly Bookkeeping Tasks

Weekly bookkeeping is about keeping the day-to-day records current. These tasks stop small errors from becoming a month-end mess.

1. Check new bank transactions and match them to invoices, bills, receipts or payments.
2. Send invoices for completed work using the create an invoice guide.
3. Record income received on the spot with a direct receipt.
4. Follow up overdue invoices and review your accounts receivable.
5. Upload receipts for business expenses while the details are still fresh.
6. Review any unusual payments before they are forgotten.

If your business has many small transactions, weekly bank reconciliation is especially useful. It helps you find missing receipts, duplicate entries and customer payments that have not been matched.

Monthly Bookkeeping Tasks

Monthly tasks give you a clear picture of how the business is tracking. They are also the foundation for reliable tax and management reporting.

Reconcile Bank Accounts

Complete your bank reconciliations for every bank account and credit card. The goal is simple: your accounting records should agree with the real bank statement.

If you are setting up a new file, make sure your starting figure is correct first. The opening bank balance guide explains how to enter and reconcile the first balance.

Review Customer Invoices

Run through your unpaid invoices and separate them into:

• invoices not yet due
• invoices due now
• invoices overdue
• invoices that may need a credit note, refund or write-off

This protects cash flow and keeps your accounts receivable ageing meaningful.

Check Supplier Bills

Review unpaid bills and supplier statements. These balances sit in accounts payable, so they affect your short-term cash position.

Even if you do not enter every bill formally, keep enough supporting records to explain what was purchased, who was paid and whether any GST or VAT was included.

Review Profit and Loss

Your monthly Profit and Loss report shows whether the business made money over the period. Look for:

• revenue that looks unusually high or low
• expenses coded to the wrong account
• one-off costs that should be explained
• missing payroll, rent, software or finance costs

If the report looks wrong, it usually means a transaction was coded to the wrong account or missed altogether.

Quarterly Bookkeeping Tasks

Quarterly bookkeeping is often tied to tax reporting, but it is also a good time to step back and check the health of the business.

Prepare GST, VAT or Sales Tax

If your business reports GST, VAT or sales tax, compare the tax collected on sales with the tax paid on purchases. In Gimbla, the GST, VAT and Sales Tax guide shows how to clear the liability correctly after lodging.

Australian businesses can also use the BAS glossary and GST glossary for plain-English definitions.

Review Cash Flow

Profit is not the same as cash. A business can be profitable and still feel short of cash if customers are slow to pay or if large costs are due soon.

Use your cash flow statement, cash budget, and our guide to mastering your cash flow to spot pressure early.

Check Payroll and Super

If you employ staff, review payroll records, leave balances, PAYG withholding and superannuation. For contractors who may need super, the paying super for contractors guide explains the Gimbla workflow.

Year-End Bookkeeping Tasks

Year-end bookkeeping is much easier when the weekly and monthly work is already done.

At year end, review:

• unpaid customer invoices and possible bad debts
• unpaid supplier bills
• fixed assets and depreciation
• loans, owner drawings and director accounts
• payroll reports and employee records
• GST, VAT or sales tax balances
• bank accounts and credit cards

For assets, check whether purchases should be expensed immediately or recorded as CapEx and depreciated over time. The depreciation user guide walks through an example in Gimbla.

A Simple Bookkeeping Routine

Here is a practical rhythm that works for many small businesses:

Timing	What to do
Weekly	Send invoices, upload receipts, match obvious bank transactions
Monthly	Reconcile accounts, review unpaid invoices, check P&L and balance sheet
Quarterly	Prepare GST/BAS, review cash flow, check payroll and super
Year end	Review assets, liabilities, payroll, tax balances and reports

You do not need to make bookkeeping complicated. Keep the routine small, repeatable and easy to review. Once your records are up to date, your accounting software becomes more than a storage system. It becomes a decision-making tool.
