Key takeaways

• Follow all seven steps of the accounts payable process — from placing orders to recording payment — to avoid missed payments, reduce errors, and keep your supplier relationships strong.
• Centralise and verify every invoice as soon as it arrives, checking that goods or services received match the invoice details before approving payment, so you only pay for what you actually received.
• Schedule payments strategically by timing them when cash is available and early-payment discounts apply, and contact suppliers early if a delay is likely to protect your business reputation.
• Automate your accounts payable tasks — such as scanning invoices, forecasting cash flow, and scheduling payments — to cut down on manual admin, reduce human error, and free up time for higher-value work.

What is accounts payable?

Accounts payable (AP) is the money your business owes to suppliers for goods and services you've received but haven't yet paid for. The accounts payable process covers every step from placing orders to making final payments. It helps you track what you owe and when it's due. This is crucial for determining when to recognise a financial liability under accounting standards.

Accounts payable vs accounts receivable

Accounts payable (AP) is money you owe to suppliers. Accounts receivable (AR) is money customers owe to you. Both affect your cash flow, but in opposite directions.

Here's how they compare:

• Accounts payable: covers bills you need to pay for goods and services received
• Accounts receivable: covers invoices you've sent to customers for payment

Managing both effectively gives you a clearer picture of your financial position. When AP exceeds AR for too long, cash flow tightens. When AR exceeds AP, you have more flexibility.

Why it matters

Effective accounts payable management protects your cash flow and keeps supplier relationships strong. When you pay on time and track your bills accurately, you avoid late fees, maintain credit terms, and build trust with the people you rely on.

Key benefits include:

• Build supplier relationships: paying on time helps you secure early payment discounts and negotiate better terms
• Control cash flow: organised AP prevents cash shortages and improves financial planning
• Protect your business reputation: reliable payment history builds trust with suppliers and vendors

When managed through accounting software, AP tracking helps you avoid cash shortages and plan payments with confidence.

What is full cycle accounts payable

Full cycle accounts payable is the complete end-to-end process of managing your bills. It covers everything from receiving an invoice to making the final payment and updating your records, helping you keep every transaction accurate and on time.

Accounts payable process steps

The accounts payable process involves seven key steps that take you from initial purchase to final payment. Following this systematic approach helps you avoid missed payments, reduce errors, and maintain strong supplier relationships.

1. Placing orders

Placing orders sets the foundation for smooth accounts payable processing. Getting this step right prevents invoice disputes and payment delays later.

Essential steps include:

1. Review requirements: verify that quotes match your needs and budget before proceeding
2. Negotiate terms: confirm payment due dates and discuss flexibility options upfront
3. Authorise purchase: assign purchase order numbers for tracking and expense management
4. Provide details: share the correct invoicing address to prevent processing delays

2. Receiving invoices

Receiving invoices efficiently prevents delays and missed payments. When invoices get lost in email or scattered across systems, bills slip through the cracks.

Best practices include:

1. Centralise invoices: use a dedicated email address to collect all bills in one location
2. Review immediately: check invoices upon arrival to identify discrepancies early
3. Automate processing: set up accounting software to scan emailed bills and track due dates automatically

3. Approving (or disputing) invoices

Approving invoices ensures you only pay for what you actually received. Verifying invoices catches errors, prevents duplicate payments, and protects your cash.

Key verification steps:

1. Check accuracy: confirm that goods or services received match invoice details and pricing
2. Get approvals: forward to relevant managers for sign-off when required
3. Address disputes quickly: contact suppliers immediately about errors to avoid payment delays

Note: official payment timelines often don't begin until you receive a correctly rendered eInvoice.

4. Recording the amount owed

Recording the amount owed creates accurate financial records and helps you comply with tax requirements, ensuring you have the documents needed to compile a list of creditors at 30 June for your annual income tax. Documenting properly now saves time at tax season and during audits.

If using an accrual basis, you must compile a list of creditors to determine your expenses for income tax purposes. Businesses registered for GST must choose to report GST on either a cash or non-cash basis.

5. Scheduling payment

Scheduling payment balances cash flow with supplier relationships. Paying too early can strain your cash reserves, while paying late damages trust and may incur penalties.

Strategic considerations include:

1. Optimise timing: schedule payments when cash is available and early-payment discounts apply
2. Monitor cash flow: use accounting software forecasts to confirm payment feasibility
3. Plan ahead: contact suppliers early if payment delays are likely
4. Manage credit wisely: avoid high-interest credit unless absolutely necessary for business continuity

Note: some government policies include a pay interest policy for late payments.

6. Executing payment

Executing payment completes the accounts payable cycle and maintains supplier trust. This is where your planning turns into action and money leaves your account.

Reliable methods include:

1. Automate payments: set up recurring payments for regular suppliers
2. Schedule payment sessions: dedicate specific times weekly for processing payments
3. Use software reminders: let your accounting system alert you to upcoming due dates

7. Recording payment

Recording payment finalises the accounts payable process and updates your financial records. This step ensures your books reflect reality and your reports stay accurate.

Final steps include:

1. Update accounting records: enter expense transactions (cash accounting) or mark invoices as paid (accrual)
2. Clear accounts payable: move paid invoices out of outstanding payables
3. Confirm completion: verify that payment shows in supplier accounts and your bank records

Automating accounts payable reduces manual work and prevents costly mistakes. By automating repetitive tasks, you free up time for higher-value work and reduce the risk of human error.

Key automation features include:

• Scan invoices: capture invoice amounts and due dates automatically from emails
