Key takeaways

• Implement a three-way matching process by comparing your purchase order, goods received note, and invoice before approving any payment to prevent overpayment, fraud, and paying for goods you didn't receive.
• Establish a consistent invoice receiving system using a dedicated email address and digital storage to keep all invoices organised in one place and prevent them from getting lost or delayed.
• Schedule payments strategically by considering your cash position, early payment discounts, and due dates to maintain healthy cash flow while capturing available savings from suppliers.
• Automate repetitive accounts payable tasks using accounting software to reduce manual errors, save time, and gain real-time visibility into what you owe and when payments are due.

What is accounts payable

Accounts payable (AP) is the money your business owes to suppliers for goods or services you've received but haven't paid for yet. It appears as a liability on your balance sheet.

The full-cycle AP process runs through several steps, from placing orders and receiving invoices through to approving and executing payments.

Why it matters

A well-organised accounts payable process protects your cash flow, strengthens vendor relationships, and helps you avoid costly mistakes.

Here's why AP management matters:

• Vendor relationships: Paying on time builds trust and can unlock early payment discounts or better terms.
• Cash flow visibility: Knowing what you owe and when helps you plan ahead and avoid shortfalls.
• Fewer surprises: Organised AP means fewer missed payments, late fees, and awkward conversations with suppliers.

When managed through accounting software, your AP process can give you real-time visibility into your cash flow management and help you stay on top of what's due.

What is the full cycle accounts payable process?

The full cycle accounts payable process covers every task involved in paying your business's bills, from the moment a purchase is requested until the payment is made and recorded. It's the complete journey of a bill through your business.

This cycle includes everything from creating purchase orders and receiving invoices to getting approvals, processing payments, and updating your accounting records. A smooth, full cycle process ensures accuracy and helps you manage your cash flow effectively.

Accounts payable process steps

The accounts payable process starts when you order products or services and finishes when payments are recorded. Most small businesses follow seven key steps:

1. Placing orders
2. Receiving invoices
3. Approving (or disputing) invoices
4. Recording the amount owed
5. Scheduling payment
6. Executing payment
7. Recording payment

Here's a breakdown of each step.

1. Placing orders

Placing orders is the first step in your AP process. Clear communication at this stage prevents errors and disputes later.

Before you commit to a purchase:

• Review quotes carefully: Check that pricing, quantities, and specifications match what you need.
• Confirm payment terms: Ask when payment is due and whether early payment discounts or extended terms are available.
• Check your budget: Make sure the expense fits within your planned spending.

Once you approve the purchase:

• Assign a purchase order (PO) number: This helps you track the expense and match it to the invoice later.
• Confirm invoice delivery: Let the supplier know where to send their invoice to avoid delays.

2. Receiving invoices

Receiving invoices is when you capture incoming bills and prepare them for review. A consistent intake process keeps everything organised and prevents invoices from getting lost.

Best practices for receiving invoices:

• Use a dedicated email address: Keep all invoices in one place for easier tracking and searching.
• Review invoices on arrival: Check for any unexpected charges or discrepancies while details are fresh.
• Store digital copies: Digital invoices are easier to search, organise, and back up than paper, and can significantly cut expenses. For instance, the US Treasury estimated that adopting e-invoicing could lower costs by 50%.

Software like Xero can automatically scan emailed invoices and create a report of what you owe and when it's due.

3. Approving (or disputing) invoices

Approving invoices ensures you only pay for what you actually ordered and received. This step catches errors before they become costly mistakes.

When reviewing an invoice, check that:

• The goods or services match your order: Compare the invoice to your original purchase order.
• The quantities are correct: Verify you received everything listed.
• The pricing is accurate: Confirm the amounts match your agreed terms.
• The invoice details are complete: Check for correct dates, payment terms, and your business details.

If the invoice needs sign-off from others, forward it to the relevant partners or project managers for review.

Handling disputes: Contact the supplier as soon as you spot any mistakes. Addressing issues while the transaction is fresh makes resolution faster and easier.

4. Three-way match process

Three-way matching is a verification method that compares three documents before approving payment: the purchase order, the goods received note (or delivery receipt), and the invoice.

This process helps you:

• Prevent overpayment: Catch pricing errors or duplicate charges before paying.
• Avoid paying for undelivered goods: Confirm you received what you ordered.
• Reduce fraud risk: Create a paper trail that makes unauthorised payments harder to slip through. Fraudulent transactions can cost a company an estimated 5% of its annual revenue.

Here's how it works:

1. Compare the purchase order to the invoice: Check that quantities, prices, and terms match.
2. Compare the goods received note to the invoice: Verify you received everything you're being charged for.
3. Approve or flag discrepancies: If all three documents match, approve the invoice for payment. If not, investigate before paying.

For small businesses processing many invoices, accounting software can automate three-way matching and flag discrepancies for review.

5. Recording the amount owed

Recording the amount owed adds the invoice to your accounting records so you can track what you owe and when it's due.

How you record the expense depends on your accounting method:

• Accrual accounting: Record the expense as soon as you receive and approve the invoice, even before you pay it.
• Cash accounting: Record the expense only when you make the payment.

Make sure to note the payment due date so you can schedule payment on time.

6. Scheduling payment

Scheduling payment is about timing your payments to balance cash flow with capturing any available discounts.

When scheduling payments, consider:

• Your cash position: Make sure you'll have funds available on the payment date.
• Early payment discounts: Some vendors offer discounts for paying ahead of the due date.
• Payment terms: Understand your options, such as net 30 or net 60 terms.

If you're using accounting software, scheduled payments flow directly into your cash flow forecast. You can see whether you'll have the funds to cover upcoming bills and adjust if needed.

If you can't pay on time:

• Contact the supplier early to negotiate a new due date or payment plan.
• Avoid relying on credit cards or bank credit, as interest costs add up.
• If cash flow is consistently tight, talk to a bookkeeper or accountant about your options.

7. Executing payment

Executing payment is when you follow through and pay the invoice as scheduled. This step seems simple, but missed payments can damage vendor relationships and trigger late fees.

To make sure payments happen on time:

• Set up automated payments: Schedule recurring payments for regular suppliers.
• Create a dedicated payment time: Block time weekly or fortnightly to process payments.
• Use software reminders: Set alerts for upcoming due dates so nothing slips through.

8. Recording payment

Recording payment completes the AP cycle by updating your records to show the invoice has been paid.

Once payment is made:

• Mark the invoice as paid: Update your accounting records to reflect the payment.
• Reconcile with your bank statement: Match the payment to your bank transaction to keep your books accurate.
• File the documentation: Store the paid invoice and payment confirmation for your records.

If you use cash accounting, this is when you record the expense in your ledger. The paid invoice is no longer part of accounts payable.

How to automate accounts payable

Accounts payable automation uses software to handle repetitive AP tasks, reducing manual work and the risk of errors. It's a rapidly expanding field, with the global market projected to grow at a compound annual growth rate of 12.8% through 2030.

FAQs on accounts payable process

Still have questions about managing accounts payable? Here are answers to some common concerns.

What is the three-way match in accounts payable?

Three-way matching compares three documents before approving payment: the purchase order, the goods received note, and the invoice. This verification step helps prevent overpayment, fraud, and paying for goods you didn't receive.

How long does the accounts payable process typically take?

Processing time varies by business size and method. Research shows the average time to process an invoice manually is 14.6 days, while automated systems can reduce this to around three days.

What's the difference between accounts payable and accounts receivable?

Accounts payable (AP) is money you owe to suppliers for goods or services received. Accounts receivable (AR) is money owed to you by customers for goods or services you've provided. AP is a liability; AR is an asset.

Can I manage accounts payable without accounting software?

Yes, though software makes the process faster and more accurate. Currently, 86% of small and medium-sized businesses still manually enter invoice data. You can track AP using spreadsheets or paper records, but software automates data entry, sends payment reminders, and provides real-time visibility into what you owe.

What are the most common accounts payable mistakes?

Common AP errors include duplicate payments, missed early payment discounts, paying incorrect amounts, losing invoices, and late payments that damage vendor relationships. Late payments are especially common; one study found that only 36% of invoices in the US are paid on time. A consistent AP process and automation can help prevent these mistakes.
