The accounts payable process: An essential guide for Aussie Businesses

Accounts payable (AP) represents money a business owes to suppliers for goods or services received. It is a current liability on the balance sheet showing outstanding vendor payments. When businesses purchase on credit, they create accounts payable entries that must be settled within the agreed terms.

Accounts payable tracks all short‑term debts owed to suppliers. This financial obligation typically requires payment within 30, 60, or 90 days depending on vendor agreements.

Understanding what accounts payable means in accounting helps maintain healthy cash flow and strong supplier relationships.

Explore how accounts payable works in practice and why proactive cash flow management matters.

In this blog, we will walk through the step‑by‑step accounts payable process, practical examples and industry best practices. You’ll also discover the differences between accounts payable (AP) and accounts receivable (AR), the key functions and responsibilities of AP teams and how automation can streamline workflows.

Finally, we’ll explore outsourcing options, software requirements and the essential KPIs finance teams should track to optimise efficiency and strengthen vendor relationships.

What is Accounts Payable Process?

The accounts payable (AP) process is the end-to-end workflow a business uses to receive, verify, approve, record and pay supplier invoices for goods or services, typically within agreed credit terms. It ensures liabilities are accurate, payments are timely and vendor relationships and cash flow are managed effectively.

Step-by-Step Accounts Payable Process

Below is the step-by-step process mentioned for accounts payable:

• Vendor Onboarding & Master Data Set up vendors with verified legal/tax IDs, bank details and agreed terms. Restrict who can create or modify vendor records.
• Purchase Requisition & PO Creation Raise approved requisitions and issue purchase orders with quantities, prices, taxes and delivery terms.
• Goods/Services Receipt Record receipt or service confirmation against the PO, including partials and returns, this forms the basis for matching and accruals.
• Invoice Receipt & Data Entry Capture invoices from email, portal, or EDI and record vendor details, invoice number, PO references, amounts, taxes and payment terms. Screen for duplicates. Our data entry services streamline this step for greater accuracy and efficiency.
• Invoice Verification & Matching Perform 2-way or 3-way matching against the PO and receipt. Route discrepancies for resolution before approval. Knowing what to put on an invoice to get paid faster reduces matching errors and speeds up the entire cycle.
• Tax Coding & Compliance Apply correct GST/VAT codes, validate tax IDs and retain documents for audits and filings.
• AP Approval Workflow Route invoices by threshold and cost centre. Approvers validate legitimacy, coding, budget and receipt evidence before authorising.
• Payment Processing & Controls Review due dates and discount opportunities; exclude blocked invoices. Execute payment runs with dual control, updating the sub-ledger and bank records automatically. Enforce segregation of duties for bank file release and verify any bank detail changes.
• Vendor Reconciliation & Dispute Resolution Reconcile vendor statements regularly to catch missing invoices or unapplied credits. Log disputes, obtain credit notes and track to closure.
• Record Keeping & Period Close Archive POs, GRNs, invoices, approvals and remittances with defined retention schedules. Reconcile the AP sub-ledger to GL and bank statements. Understanding the importance of record keeping for businesses is fundamental here, accurate archives support audits, compliance and informed decision-making. Post accruals for received-not-invoiced items and complete month-end close activities.
• KPIs & Continuous Improvement Track cycle time, first-pass match rate, duplicate hit rate, discount capture and on-time payment. Use insights to fix root causes and refine AP policies.

Accounts Payable Examples

Common AP items include supplier invoices for inventory, utility bills and professional services.

Accounts payable accounting example: A business purchases $5,000 in office supplies on 30-day terms.

The journal entry debits Office Supplies Expense and credits Accounts Payable for $5,000. When payment is made, the entry debits Accounts Payable and credits Cash. Other examples include rent payments, insurance premiums, maintenance contracts and equipment purchases on credit.

Common Accounts Payable Challenges

Even with a structured process, AP teams regularly face obstacles that slow down payments, strain vendor relationships and create compliance risks.

• Manual Data Entry Errors Relying on manual invoice capture increases the risk of duplicate payments, incorrect coding and missed entries.
• Invoice Matching Discrepancies Mismatches between purchase orders, receipts and invoices delay approvals and hold up vendor payments.
• Slow Approval Workflows Paper-based or email-driven approvals create bottlenecks, causing missed due dates and lost early payment discounts.
• Fraud and Compliance Risks Weak segregation of duties and unverified vendor records expose businesses to payment fraud and regulatory penalties.
• Poor Record Keeping Disorganised archives make audits difficult, slow down month-end close and increase the risk of compliance failures.
• Vendor Reconciliation Gaps Unreconciled vendor statements lead to missing invoices, unapplied credits and damaged supplier relationships over time.

Best Practices to Improve Accounts Payable Process

Below is the list of some of the accounts payable best practices:

1. Implementing strong controls

Segregate duties across invoice entry, approval and payment execution to prevent fraud and maintain checks and balances within the AP function.

2. Document Clear Policies

Define and communicate approval hierarchies, payment terms and exception handling procedures to ensure consistency and compliance across the organisation.

3. Automate Invoice Processing

Replace manual data entry with OCR-based capture and automated matching to reduce errors, cut processing time and improve first-pass accuracy.

4. Manage Vendor Master Data

Keep vendor records accurate and up to date. Regular statement reconciliation prevents duplicate payments and strengthens supplier relationships.

5. Optimise Payment Scheduling

Capture early payment discounts where beneficial and prioritise payments by due date, discount ROI and vendor importance to protect cash flow.

6. Strengthen Compliance and Audit Trails

Enforce access controls, maintain complete documentation and conduct regular audits to stay audit-ready and minimise regulatory risk.

7. Monitor AP Metrics Regularly

Track days payable outstanding, invoice processing time, error rates and discount capture consistently to identify gaps and drive continuous improvement.

Accounts Payable vs Receivable

Accounts Payable (AP) vs Accounts Receivable (AR) represents two key sides of business transactions. While accounts payable tasks focus on settling obligations with suppliers, accounts receivable ensures timely collection from customers. Together, they form the foundation for accurate financial reporting and healthy cash flow.

Aspect	Accounts Payable	Accounts Receivable
Definition	Money owed to vendors	Money owed by customers
Balance Sheet	Current liability	Current asset
Cash Flow Impact	Cash outflow	Cash inflow
Goal	Timely vendor payments	Prompt customer collections

Understanding both sides helps businesses optimise working capital management. Let’s understand AP & AR Roles & Responsibilities.

Accounts Payable Functions and Responsibilities

Accounts payable (AP) ensures vendors and suppliers are paid correctly and on time. Below are the key functions and responsibilities of an AP team.

Core AP Tasks

The accounts payable tasks involve the full cycle of managing payments. Typical functions include:

• Receiving, verifying and matching invoices with purchase orders
• Coding and routing for approval based on company policy
• Scheduling and executing payments (cheques, EFT, or online transfers)
• Maintaining vendor records and addressing payment queries

The process of invoices in accounts payable follows a structured flow:

• Invoice verification against purchase orders or contracts
• Coding expenses to the right account
• Approval routing to managers or budget holders
• Payment scheduling to ensure timely settlements

Accounts Payable Duties

The primary accounts payable duties are centred around financial accuracy, compliance and vendor relationships. These include:

• Recording all liabilities promptly and accurately
• Resolving invoice discrepancies and payment disputes
• Ensuring payments are made within agreed credit terms
• Preventing duplicate or fraudulent payments
• Supporting month-end and year-end closing activities

Team Roles

Accounts payable roles and responsibilities depend on the size and complexity of the business.

• In larger organisations: roles are often split among specialists for invoice entry, approval coordination, vendor management and payment processing.
• In smaller businesses: one person may handle all accounts payable functions, from receiving invoices to releasing payments.

Strong AP teams also collaborate with procurement and finance departments to improve cash flow management, vendor satisfaction and overall financial health.

Accounts Receivable: Roles & Responsibilities

On the other hand, AR focuses on customer collections. Key responsibilities include:

• Issuing invoices to clients
• Monitoring outstanding balances
• Following up on overdue payments
• Reconciling customer accounts

Why both AP and AR matters?

Efficient management of AP and AR helps businesses strike a balance between paying obligations on time and collecting revenue without delays. This balance is critical for maintaining positive cash flow, strengthening vendor and customer trust and supporting long-term growth.

What is AP Automation?

Accounts payable automation uses technology to streamline invoice processing and payment workflows. Automated systems capture invoice data, route for approval and schedule payments with minimal manual intervention.
