10 must-do tasks for a complete monthly bookkeeping routine
Each month, certain bookkeeping processes need to be completed to maintain accurate records and meet reporting obligations. A reliable monthly bookkeeping checklist should include action items across the following areas:
1. Record and categorise transactions:
Recording and categorising transactions is a key part of keeping financial records accurate. When done consistently, it shows exactly where income comes from and how expenses are managed.
Maintaining well-structured records also takes the pressure off during tax time. With everything in the right place, there is less room for error and more clarity for reporting.
Tools like Dext and Hubdoc can make this process easier. They extract key details from receipts and invoices automatically, sorting them by date, amount, tax, and category. These tools also connect with accounting platforms such as QuickBooks and Xero, helping reduce manual work and keeping your data accurate and up to date.
2. Review your accounts receivable:
Unpaid invoices can quietly impact your business. That’s why it’s important to stay on top of your accounts receivable.
- Reviewing your receivables helps you track what’s overdue and understand how long payments have been pending.
- It gives you early insight into potential cash flow gaps and helps you manage risk more effectively.
The more clarity you have around incoming payments, the more confidently you can make business decisions.
3. Manage accounts payables:
Efficiently managing accounts payable helps you in the following ways:
- Avoids late fees by ensuring timely and accurate bill payments.
- Maintains strong relationships with vendors and suppliers through consistent, reliable payments.
- Protects your cash flow by keeping expenses predictable and manageable.
- Improves financial clarity with a clear view of upcoming obligations and due dates.

4. Reconcile payroll:
Payroll reconciliation helps ensure employees are paid correctly and payroll taxes are accurately reported. By regularly checking payroll data, businesses can avoid mistakes like overpayments, underpayments, and tax miscalculations. This process supports better budgeting, planning, and compliance, while also helping to prevent costly fines and penalties.
5. Prepare financial statements:
Get a clear snapshot of your business’s financial health by preparing accurate financial statements each month. This includes key reports like income statements, balance sheets, cash flow statements, and summaries of your bank and credit card accounts. These documents help you understand your cash position, track performance, and make confident business decisions.
6. Review the month-end financials thoroughly:
Month-end close helps identify errors early and ensures financial statements reflect the true financial position of the business. Establish a regular process for reviewing and recording adjusting journal entries, such as accruals or prepayments. Software like MYOB or Xero can automate many of these entries.
7. Check compliance and deadlines:
Meeting tax obligations and filing requirements on time helps maintain good standing with regulatory authorities and reduces the risk of penalties. Staying compliant also supports the financial stability of the business. To stay organised, develop a compliance calendar that outlines all key tax payment and lodgment dates relevant to your business.

8. Track stock levels (If applicable):
Regularly tracking stock levels helps you avoid both overstocking and running out of items, so you can respond effectively to customer demand. It also provides insights into purchasing trends, helping you plan inventory more accurately and make informed decisions for future stock management.
9. Backup financial data:
Protecting your financial data is key to avoiding setbacks caused by technical failures, accidental file loss, or security breaches. These issues can take significant time to fix and may result in financial strain. By creating secure copies of important records like reports, ledgers, and profit and loss statements, you can restore your data quickly when needed.

10. Review financial performance:
Regularly reviewing financial performance helps identify errors in your records and keeps your finances aligned with the budget. Comparing actual results against planned figures allows you to spot discrepancies early, make timely adjustments, and maintain accurate financial reports.
