Accounts Receivable vs. Accounts Payable

A business can be profitable on paper and still struggle to pay its bills. Why? It often comes down to timing: Money may be owed to the company, but it hasn’t arrived before payments to suppliers, employees, and other third parties are due.

That’s why accounts receivable (AR) and accounts payable (AP) are so important. Together, they show how money moves into and out of a business, influence working capital, and help finance teams understand the company’s short-term financial health.

Although AR and AP sit on opposite sides of the balance sheet, they’re closely connected. Effective receivables and payables management helps businesses collect customer payments faster, pay vendors accurately, maintain strong relationships, and protect cashflow.

What is the meaning of AP & AR?

The meaning of AP and AR have to do with the direction the money is moving:

• Accounts receivable is money that customers owe the business.
• Accounts payable is money that the business owes its suppliers and vendors.

Both balances usually result from transactions completed on credit rather than immediate payment.

For example, when a company delivers a product to a customer and gives them 30 days to pay, the unpaid invoice becomes part of AR. When that same company receives an invoice from a supplier and has 30 days to pay it, the outstanding bill becomes part of AP.

What is AR in accounting?

AR in accounting represents amounts a company expects to collect from customers for goods or services already provided.

Another name for AR is trade receivables, although it may also include other amounts owed to the business.

AR is a current asset because it represents money that’s expected to be converted into cash, generally within one year. In many businesses, customer credit terms require payment within 30, 60, or 90 days.

• The AR process typically includes:
• Assessing customer creditworthiness
• Establishing credit limits and payment terms
• Creating and delivering invoices
• Tracking due dates and outstanding balances
• Sending payment reminders
• Managing disputes and deductions
• Applying incoming payments to the correct invoices
• Following up on late payments

The main objective is to collect the full amount owed in a timely manner without damaging valuable customer relationships. Businesses can also improve their ⁠AR debt collection process by strengthening communication, prioritization, and payment follow-up.

What does AP mean?

AP represents amounts a company owes suppliers, vendors, and other creditors for goods or services it's already received.

AP is classified as a current liability because the business has an obligation to pay the outstanding balance, generally within one year. Common credit terms include net 30, net 45, and net 60 days.

The AP process typically includes:

• Receiving supplier invoices
• Capturing and validating invoice data
• Matching invoices with purchase orders and receipts
• Routing invoices for approval
• Resolving exceptions and discrepancies
• Scheduling payments according to due dates
• Recording completed payments in the general ledger
• Maintaining vendor records and supporting documents

Effective AP management helps a business pay the correct suppliers the correct amounts at the correct times.

Accounting AR & AP: key differences

The primary difference between AR and AP is whether the business expects to receive money or is responsible for paying it.

AR vs. AP balance sheet classification

AR and AP appear in different sections of the balance sheet.

What type of account is AR?

AR is a current asset. It represents money the company expects to collect from customers. Once the customer submits payment, the company’s AR balance decreases, and its cash balance increases.

AP is a current liability. It represents a financial obligation the business must settle. Once the company pays a supplier invoice, both the AP balance and the company’s available cash decrease.

AR and AP balances alone don’t show the full financial position of a business. Finance teams must also consider available cash, inventory, debt, payment due dates, expected collections, and other current assets and current liabilities. These classifications also determine how AR and AP are recorded in double-entry accounting.

Is AR a debit or credit?

Because AR is an asset account, it normally has a debit balance.

When a company completes a credit sale, it debits AR and credits revenue. When the customer pays the invoice, the company debits cash and credits AR.

For a $5,000 credit sale, each journal entry would generally look like this:

A debit increases the AR balance, while a credit reduces it.

Is AP a debit or credit?

AP is a liability account, so it normally has a credit balance.

When a supplier invoice is recorded, the business typically debits the relevant expense, inventory, or asset account and credits AP. When the bill is paid, the company debits AP and credits cash.

For a $2,000 supplier invoice, each journal entry might look like this:

A credit increases the AP balance, while a debit reduces it.

What are examples of AR?

AR can arise whenever a business provides goods or services before receiving payment.

Consider a consulting company that completes a project and sends its client a $5,000 invoice with net-30 credit terms. Until the client pays, that $5,000 is recorded as AR.

Other AR examples include:

• A manufacturer ships products to a retailer and allows the retailer to pay within 60 days.
• A software company invoices a corporate customer for an annual subscription.
• A logistics provider bills a client after completing a series of deliveries.
• A landscaping company performs monthly maintenance and invoices at the end of the month.
• A healthcare provider waits for payment from a patient or insurer.
• A professional services firm bills clients for completed work.

Notes receivables can also represent money owed to a company, but they differ from standard trade receivables. A note receivable generally involves a formal written promise to pay, may include interest, and may have a longer repayment period.

What are examples of AP?

AP results from business expenses that haven’t yet been paid.

Suppose that same consulting company purchases $2,000 in computers from a technology vendor on net-30 terms. Once the computers and invoice are received, the unpaid amount is recorded in AP.

Other AP examples include:

• Invoices from suppliers for raw materials and other goods
• Inventory purchased for resale
• Utility bills for electricity, water, or internet service
• Invoices from freight and transportation providers
• Software and cloud service subscriptions
• Professional fees from attorneys, consultants, or accountants
• Office equipment and workplace supplies
• Maintenance, cleaning, and repair services

Employee wages, long-term loans, and taxes payable are also liabilities, but they aren’t usually classified as trade AP.

Do you send invoices to AP or AR?

Whether an invoice goes to AP or AR depends on whose perspective you’re considering.

When a company sends an invoice to a customer, that invoice belongs to the company’s AR process. The customer receiving the invoice generally sends it to its own AP department for review and payment.

In other words:

• The seller records the invoice in AR.
• The buyer records the same invoice in AP.

This relationship is opposite sides of the same transaction. One organization’s receivable is another organization’s payable.

Receivable & payable management: how the processes work

AR and AP involve different activities, but both require accurate information, clear internal controls, and coordination across the business.

The AR process

A typical AR process begins well before an invoice is created. The company may evaluate the customer’s credit risk, establish a credit limit, and agree on payment terms.

After a sale is completed, the AR team:

• Generates and delivers the customer invoice
• Records the amount in AR
• Tracks the invoice according to its due date
• Communicates with the customer about upcoming or late payments
• Resolves disputes, short payments, and deductions
• Receives AR payments and applies them to the correct open invoices
• Reconciles the customer account and general ledger

The AR team may also monitor the average AR balance, review aging reports, and identify customers at higher risk of paying late.

How does the AP process work?

The AP process usually begins when a business needs to purchase goods or services. Depending on the company’s policies, the purchase may require a formal purchase order and approval before the supplier fulfills the order.

After the supplier invoice arrives, the AP team:

• Captures the invoice and verifies its information
• Checks the supplier against approved vendor records
• Matches the invoice with the purchase order and receiving documentation
• Routes the invoice to the correct person for approval
• Investigates pricing, quantity, tax, or payment-term discrepancies
• Schedules payment according to the due date
• Sends payment and records it in the accounting system
• Reconciles the AP subledger with the general ledger

Strong internal controls can reduce duplicate payments, unauthorized purchases, and the risk of fraud. 

Can AP & AR be done by the same person?

In some businesses, the same person may be responsible for both AP and AR. However, the risk of fraud increases when invoice approval, payment authorization, vendor management, and reconciliation are controlled by the same person. 

Segregation of duties is an important internal control. Ideally, the person who creates a transaction shouldn’t be the only person who approves it, records it, makes the payment, and reconciles the account.

Separating AP and AR responsibilities makes it more difficult for one person to:

• Create a false vendor and authorize a payment
• Divert a customer payment
• Change supplier banking information without review
• Conceal a duplicate or unauthorized transaction
• Alter accounting records to hide an error

When complete separation isn’t practical, a business can introduce compensating controls, such as independent bank reconciliations, approval thresholds, audit trails, restricted system access, and regular management reviews.

Is AP harder than AR?

Neither AP nor AR is inherently harder. However, each process presents different challenges.

AP teams must validate large volumes of supplier invoices, manage approval workflows, prevent duplicate payments, maintain vendor data, and pay invoices according to the correct credit terms. They also need to protect the business against invoice fraud and unauthorized changes to vendor information.

AR teams must communicate with customers, resolve disputes, manage collections, apply complex payments, and balance collection goals with the customer experience. Their work directly affects revenue realization and cash availability.

The difficulty of each function depends on factors such as transaction volume, company size, process complexity, customer or supplier behavior, international operations, and the technology available to the finance team.

How AR & AP affect cashflow

AR and AP have a direct effect on working capital.

When customers pay late, the business may not have enough cash available to cover payroll, supplier payments, taxes, and other due dates. When a company pays suppliers earlier than required, it can reduce the cash available for operations.

The goal isn’t to build up AR or delay every payable. Finance teams need to accelerate collections while managing outgoing payments according to agreed terms:

• AR teams should make it easy for customers to receive invoices, resolve issues, and pay on time.
• AP teams should pay suppliers according to agreed terms, capture available discounts, and avoid unnecessary late fees.
• Treasury and finance leaders should compare expected customer payments with upcoming supplier obligations.
• The company should maintain enough liquidity to handle unexpected expenses or collection delays.

Lenders and potential investors may also review AR and AP balances when assessing liquidity and overall financial health.

Important AR & AP performance metrics

Finance teams use different KPIs to evaluate the effectiveness of AR and AP.

AR turnover ratio

The AR turnover ratio measures how efficiently a company collects its average AR balance. Average AR is generally calculated by adding the beginning and ending AR balances and dividing the result by two.

A higher turnover ratio generally indicates that the business collects customer payments more frequently. However, results should be compared with the company’s credit terms, industry, customer base, and historical performance. Tracking the AR turnover ratio over time can reveal whether collections performance is improving or declining.

Days sales outstanding (DSO)

DSO estimates the average number of days it takes a business to collect payment after a credit sale.

A rising DSO may indicate late payments, invoice delivery problems, customer disputes, ineffective collections, or unfavorable credit terms.

Days payable outstanding (DPO)

DPO estimates the average number of days a company takes to pay suppliers.

A very low DPO may mean the company is paying sooner than required and sacrificing available cash. A very high DPO could indicate cash constraints and may lead to strained vendor relationships, interrupted supplies, and late fees.

Additional performance indicators

Useful AP and AR metrics can also include:

• Percentage of invoices paid on time
• Percentage of customer payments received by the due date
• Invoice exception rate
• Cost to process an invoice
• Collection effectiveness index
• Bad debt percentage
• Number of duplicate payments
• Percentage of available early payment discounts captured
• Amount of unapplied cash
• Average time required to resolve disputes

How automation improves AP & AR

Manual processes make it difficult to manage growing transaction volumes. Paper invoices, spreadsheets, email approvals, and disconnected tracking systems can create delays, errors, and limited visibility.

AP automation

AP automation software can capture supplier invoice data, validate invoices, identify potential duplicates, and route documents through digital approval workflows.

Modern AP software can also:

• Match invoices with purchase orders and receipts
• Flag exceptions for review
• Maintain a complete audit trail
• Track invoice and payment statuses
• Support segregation of duties
• Detect suspicious invoice or vendor activity
• Schedule payments based on due dates and credit terms
• Integrate transactions with the ERP and general ledger

Automating routine work allows AP teams to spend less time entering data and tracking approvals manually. Learn how an ⁠AP automation solution helps finance teams improve invoice processing, visibility, and control.

AR automation

AR automation software helps businesses create and deliver invoices, track customer balances, prioritize collection activities, and apply incoming payments.

AR automation software can also:

• Send invoices through customers’ preferred channels
• Provide automated reminders before and after due dates
• Give customers access to self-service portals
• Support multiple digital payment methods
• Predict which customers or invoices are likely to become overdue
• Recommend collection priorities
• Match payments with open invoices
• Track disputes and customer communications

These capabilities can accelerate collections while giving customers greater visibility into their accounts.

Why connecting AP & AR matters

AP and AR are often managed by separate teams and systems, but finance leaders need visibility across both processes.

A unified approach to source-to-pay and invoice-to-cash activities can provide a more complete picture of incoming and outgoing cash. Instead of reviewing isolated spreadsheets, finance teams can compare expected customer payments with upcoming supplier obligations and make better informed working capital decisions.

Connecting these processes can help organizations:

• Improve cashflow forecasting
• Identify potential liquidity gaps earlier
• Standardize financial data and reporting
• Strengthen internal controls
• Monitor payment and collection performance
• Improve relationships with customers and vendors
• Give the finance team more time for analysis and strategic work

With Esker’s AI-powered automation solutions, businesses can digitally manage key source-to-pay and invoice-to-cash activities while improving visibility, efficiency, and control across their finance operations.

AR vs. AP: the bottom line

AR and AP represent opposite sides of a company’s financial activity. AR tracks money customers owe the business, while AP tracks money the business owes its suppliers and vendors.

Managing both effectively is essential. Strong AR practices accelerate incoming cash and reduce collection risk. Strong AP practices improve payment accuracy, protect supplier relationships, and help the company retain cash until payments are due.

By automating routine tasks and connecting AP and AR information, finance teams can improve cashflow visibility, strengthen internal controls, and make more confident decisions about the company’s financial health.
