Accounts payable (AP) has two key meanings. As an accounting term, it refers to the money a business owes its suppliers for goods or services received but not yet paid. Recorded as a short-term liability on the balance sheet, AP is central to a company’s financial operations and liquidity management.
As part of the office of the CFO, the AP function is tasked with managing these liabilities. It plays a strategic role in optimizing working capital, preserving vendor relationships and enabling efficient financial reporting.
Below, we walk through the accounts payable process, key performance metrics, job roles, best practices, and how AP automation is rapidly transforming the function.
What Is Accounts Payable? Meaning, Definition & Importance
As an accounting term, accounts payable (AP) refers to the cumulative amount a company owes to suppliers or service providers for goods or services purchased on credit. When referring to a company’s obligations or ability to pay, the term AP is often used interchangeably with terms like payables, bills payable or payability.
AP is recorded as a current liability on the balance sheet and reflects short-term obligations that are typically due within 30 to 90 days. Importantly, AP is not an expense account but a liability account, signifying the company’s responsibility to settle these dues.
Beyond the balance sheet, AP also refers to the department or function responsible for managing these liabilities. Typically part of the broader finance organization, AP is responsible for ensuring that all outstanding invoices are tracked, verified, approved, and paid accurately and on time.
Effective AP management ensures a balance between outgoing cash flow and operational needs. Businesses that delay payment beyond terms may damage relationships and face late fees, while those that pay accurately and on time preserve vendor trust, which can open the door to favorable terms or early-payment discounts. However, businesses that pay too quickly may miss the opportunity to hold cash longer for liquidity or interest. In short, accounts payable is a key lever in maintaining financial health.
Accounts Payable vs. Accounts Receivable
Accounts payable (AP) and accounts receivable (AR) represent opposite sides of a transaction:
- AP involves money a company owes to external vendors, making it a liability.
- AR represents money owed to the company by its customers and is classified as an asset.
For example, when Company A purchases equipment on credit from Company B, A records the transaction under AP while B records it under AR.
This distinction between AP and AR impacts cash flow management and overall financial planning. AP focuses on extending payments within agreed terms to conserve cash, while AR focuses on collecting payments quickly to bring cash in. In some small or mid-sized companies, the same staff may handle accounts payable and receivable, but the skill sets and goals differ.
Accounts Payable Process (Procure-to-Pay)
The AP process, often referred to as procure-to-pay, is a structured workflow that governs how a company purchases and pays for goods or services. The process begins with a purchase requisition, which leads to a formal purchase order (PO) being issued to a supplier. Upon receipt of goods or services, the supplier sends an invoice, which is reviewed and compared to the PO and delivery documentation in a three-way match.
Once approved, the invoice is entered into the accounting system by debiting an expense or asset account and crediting AP. The payable is scheduled for payment according to the supplier’s terms. After payment is made, AP is debited, and cash is credited. Finally, reconciliation and reporting ensure that all invoices are accounted for, and payments are properly tracked.
Recurring transactions, such as electricity bills and outstanding salary journal entries, are also processed through AP. Companies may use default purchase accounts in their enterprise resource planning (ERP) systems to categorize these transactions automatically.
AP Journal Entries & Examples
Recording AP transactions accurately is critical in double-entry accounting systems. When a company incurs payment, the accounting system credits AP and debits the relevant expense or asset account. For instance, if a business receives a $780 invoice for office supplies:
- Debit: Office Supplies Expense $780
- Credit: Accounts Payable $780
Once the invoice is paid:
- Debit: Accounts Payable $780
- Credit: Cash $780
This illustrates that AP is a credit, as it increases liability. When the company settles the obligation, AP is debited, reducing the balance, and cash is credited to reflect the outflow. Common terms such as bills payable, payable amount or sum of AP refer to the total short-term liabilities a company has at a given point. The purchase account is a default used in many systems to allocate invoice amounts based on vendor or expense type. Accounting teams must ensure the accuracy of these entries to maintain compliance and financial transparency.
Key AP Metrics: Turnover Ratio & Days Payable Outstanding (DPO)
Two essential metrics help evaluate the efficiency of a company’s AP process: the AP turnover ratio and days payable outstanding (DPO).
The AP turnover ratio is calculated as:
Accounts Payable Turnover = Net Credit Purchases ÷ Average Accounts Payable
This ratio measures how frequently a company pays off its AP during a period. A higher ratio suggests faster payment cycles, while a lower ratio may indicate delayed payments or strained liquidity. However, extremely high turnover may also suggest the company is not fully utilizing its available credit terms.
DPO shows the average number of days a company takes to pay suppliers:
DPO = (Average Accounts Payable ÷ Cost of Goods Sold) x 365
Monitoring DPO helps companies find the right balance between conserving cash and maintaining strong supplier relationships.

AP Roles, Careers & Skills
The AP function includes a few roles, each with unique responsibilities, as outlined in our example accounts payable job descriptions:
- AP clerks are responsible for invoice data entry, verifying accuracy, coding expenses and scheduling and processing payments.
- AP specialists process invoices, reconcile statements, ensure timely payments to vendors and maintain strong relationships with vendors and internal stakeholders.
- AP managers oversee all AP transactions within the organization, supervise a team of AP professionals, ensure compliance with company policies and procedures, maintain strong relationships with vendors and internal stakeholders and drive process improvements.
To succeed in these roles, AP professionals need attention to detail, knowledge of accounting principles, proficiency in ERP systems and strong communication skills. Career advancement opportunities are growing as automation shifts AP from data entry toward analytical and strategic responsibilities. For professionals managing accounts payable and receivable, cross-functional expertise can enhance career mobility.
The median total annual compensation for AP professionals varies by job title, from $52,500 for AP clerks to $90,000 for AP managers. More detailed salary information for AP professionals can be found in the AFP Enterprise Payments Salary Guide, which draws from the annual AFP Compensation and Benefits Survey.
Best Practices & Internal Controls for AP
To manage AP effectively, organizations must implement strong internal controls and follow industry best practices. First, ensure segregation of duties: invoice approval, payment authorization and vendor setup should involve different team members. Apply the three-way match to verify invoice amounts, PO details and delivery receipts before payment.
Timely payments reduce late fees and may unlock early payment discounts such as 2/10 Net 30. Companies should monitor DPO to manage cash flow while maintaining good supplier relationships. Digital workflows reduce human error and accelerate invoice processing.

AP Automation & Technology Trends
Organizations are rapidly adopting AP automation to improve efficiency and accuracy. Technologies such as optical character recognition (OCR), intelligent data capture and workflow software now handle invoice routing, approvals and even payment execution. AP automation enables remote access, reduces processing time and provides real-time visibility into liabilities and cash needs.
Emerging tools include AI for anomaly detection, machine learning for invoice categorization and blockchain for secure, transparent payments. Supplier portals improve collaboration by allowing vendors to check payment status online. Sustainability goals also drive the adoption of paperless invoicing.
