Key takeaways

• Accounts payable (AP) is the money your business owes to suppliers and vendors for goods or services you've received but haven't paid for yet.
• Keeping on top of AP helps you manage cash flow, maintain strong supplier relationships, and stay compliant with your reporting obligations.
• A clear AP process, from receiving invoices through to reconciliation, reduces errors and saves you time each month.
• Accounting software like Xero automates much of the AP cycle, so you can focus on running your business instead of chasing paperwork.

What is accounts payable?

Accounts payable (AP) is the total amount your business owes to suppliers, vendors, and creditors for goods or services you've received on credit. It's recorded as a current liability on your balance sheet, because it represents money that needs to be paid within a short period, usually 30 to 90 days.

In many businesses, "accounts payable" also refers to the team or function responsible for processing and paying supplier invoices. Whether you're a sole trader handling bills yourself or you have a dedicated bookkeeper, AP is a core part of keeping your finances organised. You can learn more about billing software and how it fits into the picture.

Common items that fall under accounts payable include:

• supplier invoices for stock or raw materials
• utility bills (electricity, internet, water)
• rent and lease payments
• contractor and freelancer fees
• subscriptions and software licences

Why accounts payable matters

Accounts payable might seem like a simple bookkeeping task, but how you manage it has a direct impact on the health of your business. Staying on top of what you owe helps you avoid late fees, keep suppliers happy, and make smarter decisions about spending.

AP touches several areas of your business.

• Cash flow management: knowing exactly what's due and when helps you plan your outgoings, so you're not caught short when a big bill lands.
• Supplier relationships: paying on time builds trust with your vendors. That can lead to better payment terms, priority service, and stronger partnerships over time.
• Accurate financial reporting: your balance sheet and profit and loss statement rely on up-to-date AP records. If your payables are wrong, your financial picture is too.
• Compliance and audit readiness: well-organised AP records make tax time and Business Activity Statement (BAS) lodgements much less stressful. You'll have a clear trail of what was paid, when, and to whom.

Accounts payable examples

Accounts payable shows up in almost every type of small business. Here are a few everyday scenarios that Australian business owners are likely to recognise.

Stocking up from a supplier. You run a cafe and order coffee beans from a local roaster on 30-day payment terms. The roaster delivers the beans and sends you an invoice. Until you pay that invoice, the amount sits in your accounts payable.

Receiving a utility bill. Your quarterly electricity bill arrives for your retail shop. You don't pay it the same day; it goes into your accounts payable until the due date.

Hiring a contractor. You engage a freelance graphic designer to create new packaging for your products. They invoice you on completion. That invoice is part of your accounts payable until it's settled.

Purchasing equipment on credit. You buy a new commercial oven for your bakery on a 60-day trade account. The amount owed to the equipment supplier is recorded as accounts payable on your balance sheet until you've paid in full.

How the accounts payable process works

The AP process follows a consistent cycle, from the moment you receive an invoice to the point where the payment is reconciled in your books. Following these steps helps you stay organised and avoid costly mistakes. For a deeper dive, see this accounts payable process guide.

1. Receive the invoice

The process starts when a supplier sends you an invoice for goods or services delivered. This might arrive by email, post, or through a tool like Hubdoc, which automatically captures and stores bills and receipts in the cloud. If you're new to invoicing, this guide to invoices covers the basics.

2. Verify the details

Check the invoice against what was actually ordered and received. This is sometimes called 3-way matching: comparing the purchase order, the delivery receipt, and the invoice to make sure everything lines up. It catches errors and prevents you from paying for something you didn't receive.

3. Approve the payment

Once verified, the invoice needs to be approved by the right person in your business. For sole traders, that's you. For larger teams, you might set up approval workflows so the right people sign off before any money leaves the account.

4. Schedule the payment

After approval, schedule the payment according to the supplier's terms. Some businesses pay on the due date to hold onto cash as long as possible. Others pay early to take advantage of early payment discounts.

5. Make the payment

Pay the supplier using your preferred method: bank transfer, direct debit, or card payment. Record the payment against the invoice in your accounting software so the amount moves out of your accounts payable.

6. Reconcile the transaction

Match the payment in your accounting software to the corresponding bank transaction. Reconciliation confirms that the money left your account and the invoice is fully settled. In Xero, automated bank feeds pull in transactions daily, making this step quick and straightforward.

Accounts payable vs. accounts receivable

Accounts payable and accounts receivable are 2 sides of the same coin. Understanding the accounts receivable process alongside your AP helps you manage both sides of your cash flow. Both appear on your balance sheet, but they represent opposite flows of money.

Accounts payable is money you owe to others. It's a liability. Accounts receivable is money others owe to you. It's an asset. Together, they give you a clear view of your cash flow: what's coming in and what's going out.

For example, if you sell products on 30-day terms, the unpaid invoices you've sent to customers are your accounts receivable. At the same time, the unpaid invoices you've received from your suppliers are your accounts payable. Keeping both up to date helps you understand your true financial position at any given moment.

Is accounts payable an asset or liability?

Accounts payable is a current liability. It represents money your business owes and expects to pay within 12 months, usually much sooner. It sits on the liabilities side of your balance sheet, not the assets side.

AP is classified as a liability because:

• it's an obligation to pay someone else, not money you own
• it reduces your net assets when calculated (assets minus liabilities)
• it's expected to be settled in the short term, making it a current liability rather than a long-term one

Payment cycles between Australian small businesses are also getting faster. Suppliers were paid in an average of 23.9 days during the December 2025 quarter; the quickest turnaround since Xero Small Business Insights began tracking in 2017. That means AP balances are turning over faster than they used to, which has implications for how you plan your cash flow.

Understanding this distinction matters because lenders, investors, and the ATO look at your liabilities when assessing your financial health. Keeping your AP accurate and current gives a clearer, more trustworthy picture of where your business stands.

Accounts payable best practices

A few simple habits can make a big difference to how smoothly your accounts payable runs. These tips are especially useful if you're managing AP yourself without a dedicated finance team.

• Process invoices promptly: don't let bills pile up. Entering invoices into your accounting software as soon as they arrive keeps your records accurate and helps you avoid late fees.
• Match invoices to purchase orders: checking that what you ordered matches what you received and what you're being billed for catches errors before you pay.
• Take advantage of early payment discounts: some suppliers offer a small discount (for example, 2% off if paid within 10 days). If your cash flow allows it, these savings add up over a year.
• Reconcile regularly: don't wait until the end of the quarter. Weekly or fortnightly reconciliation in Xero keeps your books clean and makes BAS time much simpler.
• Set up approval workflows: even in a small team, having a clear process for who can approve payments helps prevent duplicate or unauthorised payments.
• Go paperless: use tools like Hubdoc to capture bills and receipts digitally. It's faster, more secure, and means you're not relying on a shoebox full of paper invoices.

FAQs on accounts payable

Here are some frequently asked questions about accounts payable and how it works for small businesses.

What's the difference between accounts payable and bills?

Bills and accounts payable are closely related, but they're not quite the same thing. A bill is a single invoice from a supplier, while accounts payable is the total of all unpaid bills your business owes at any given time.

Who is responsible for accounts payable?

In smaller businesses, the owner or a bookkeeper typically handles AP. Larger businesses may have a dedicated accounts payable team or outsource the function to an accountant or bookkeeper.

How does accounts payable affect cash flow?

Every dollar sitting in accounts payable is money you'll need to pay out soon. Tracking your AP closely helps you forecast cash flow and avoid situations where you don't have enough funds to cover upcoming payments.

What is accounts payable turnover?

Accounts payable turnover is a ratio that measures how quickly you pay your suppliers. A higher ratio means you're paying faster; a lower one suggests you're taking longer to settle invoices. It's calculated by dividing total supplier purchases by average accounts payable over a period.

What are common accounts payable challenges?

The most common issues include lost or duplicate invoices, late payments due to slow approval processes, and data entry errors. Automating your AP workflow with accounting software helps reduce these risks significantly.

How can automation improve accounts payable?

Automation speeds up invoice capture, reduces manual data entry, and flags duplicates or mismatches before you pay. Tools like Xero and Hubdoc handle much of this automatically, freeing you up to focus on your business.
