English:Accounts Payable and Receivable
Accounts Payable and Receivable
Introduction
Accounts Payable and Receivable are two central parts of day-to-day business accounting. They help a business control what it owes to suppliers, what customers owe to the business, when cash should move, and whether transactions have been recorded correctly. This aiMOOC is designed for apprentices, trainees, and vocational students who may work in Accounting, Bookkeeping, Business administration, purchasing, sales administration, or office management.
Accounts payable, often shortened to AP, records amounts a business owes for goods or services bought on credit. Accounts receivable, often shortened to AR, records amounts customers owe the business for goods or services sold on credit. In ordinary short-term trade situations, AP is usually a current liability and AR is usually a current asset. The exact treatment of taxes, discounts, bad debts, and reporting can vary by country, accounting framework, and company policy, so you should always follow the procedures used in your workplace.
An invoice is a key source document in both cycles. For a supplier, it supports a receivable; for the customer, the same invoice supports a payable.
Learning Goals
After completing this aiMOOC, you should be able to explain the difference between Accounts payable and Accounts receivable, identify the main documents in each process, make basic debit and credit entries, calculate due dates and simple settlement discounts, reconcile subledger balances, interpret aging reports, apply internal controls, communicate professionally with suppliers and customers, and analyze workplace cases involving payment or collection problems.
You should also be able to connect AP and AR to Working capital, Cash flow, Internal control, General ledger, Double-entry bookkeeping, and routine month-end work.
Where AP and AR Fit in Accounting
A balance sheet groups resources as assets and obligations as liabilities. Accounts receivable represents a claim on customers and normally carries a debit balance. Accounts payable represents an obligation to suppliers and normally carries a credit balance.
Although this image uses a household example, the same basic distinction between assets and liabilities helps you understand why receivables and payables appear on opposite sides of a business balance sheet.
| Feature | Accounts Payable | Accounts Receivable |
|---|---|---|
| Business perspective | Money the business owes | Money customers owe the business |
| Typical balance-sheet class | Current liability | Current asset |
| Normal balance | Credit | Debit |
| Common starting document | Supplier invoice | Customer invoice |
| Typical settlement | Business pays supplier | Customer pays business |
| Main operational risk | Incorrect, duplicate, unauthorized, or late payment | Late, disputed, misapplied, or uncollectible customer balance |
Accounts Payable
Purpose and Basic Entries
Accounts payable is created when a business receives goods or services now and agrees to pay the supplier later. AP staff or bookkeepers normally verify the invoice, check approval, code the transaction to the correct account, record the liability, schedule payment, and keep supplier balances accurate.
For a simple credit purchase of office supplies worth 1,000 monetary units, a basic entry may be:
| Account | Debit | Credit |
|---|---|---|
| Office Supplies Expense | 1,000 | |
| Accounts Payable | 1,000 |
When the business later pays the supplier, a basic entry may be:
| Account | Debit | Credit |
|---|---|---|
| Accounts Payable | 1,000 | |
| Cash or Bank | 1,000 |
The first entry recognizes the expense or asset and the obligation. The second removes the obligation and reduces cash. The precise expense or asset account depends on what was purchased and on the accounting system used.
Purchase-to-Pay Workflow
A controlled purchase-to-pay process often follows this sequence: internal need, purchase authorization, purchase order, receipt of goods or services, supplier invoice, matching, approval, posting, payment, and reconciliation. Some organizations use different names or steps, but each stage should leave a clear audit trail.
A Purchase order states what the organization has authorized a supplier to provide. It can include item descriptions, quantities, prices, delivery information, and terms.
Two-Way and Three-Way Matching
A two-way match compares the supplier invoice with the purchase order. A three-way match adds evidence of receipt, such as a receiving report or goods receipt. In a three-way match, staff compare what was ordered, what was received, and what the supplier billed. Differences in quantity, price, tax, freight, or other terms should be investigated according to company policy before payment is released.
Three-way matching is an important control because it reduces the risk of paying for goods that were not ordered, not received, or billed incorrectly. It does not remove the need for appropriate approval, vendor controls, and separation of duties.
Supplier Master Data and Payment Controls
Supplier master data may include the supplier's legal name, address, tax information, payment terms, contact details, and bank details. Because changes to this information can affect where money is sent, access should be limited and changes should follow a documented approval process.
Good practice includes separating supplier setup from invoice approval and payment release, checking for duplicate invoices, using approval limits, reviewing unusual changes, independently verifying sensitive bank-detail changes through an approved contact method, and retaining an audit trail. Your workplace may use automated checks, but staff remain responsible for reviewing exceptions and following policy.
Accounts Receivable
Purpose and Basic Entries
Accounts receivable begins when a business makes a credit sale and invoices the customer for payment later. AR work can include customer setup, credit terms, invoicing, cash application, collection activity, dispute handling, account statements, aging analysis, and reconciliation.
For a simple service sale of 1,500 monetary units on credit, a basic entry may be:
| Account | Debit | Credit |
|---|---|---|
| Accounts Receivable | 1,500 | |
| Service Revenue | 1,500 |
When the customer pays, a basic entry may be:
| Account | Debit | Credit |
|---|---|---|
| Cash or Bank | 1,500 | |
| Accounts Receivable | 1,500 |
If inventory is sold, additional entries may also be required to recognize the cost of goods sold and reduce inventory, depending on the inventory system.
Order-to-Cash Workflow
A typical order-to-cash cycle may include customer setup, credit review, order acceptance, delivery of goods or services, invoice creation, posting to the customer account, collection follow-up, receipt of payment, cash application, and reconciliation. A strong process makes it possible to trace a customer balance back to the underlying invoice, delivery evidence, credit note, and payment.
The quality of invoice data matters. Customer name, invoice number, invoice date, due date, description, quantity, price, tax information where applicable, total amount, payment instructions, and reference details should be accurate and consistent with the sale.
Cash Application and Customer Statements
When a customer pays, the amount must be matched to the correct customer and invoice. A payment may cover one invoice, several invoices, or only part of an invoice. Remittance advice can help identify what the customer intended to settle.
If cash is posted to the wrong customer or invoice, the general ledger may still show the correct total cash received while individual customer balances are wrong. That is why cash application and customer-account reconciliation are important.
Cheques are now less common in many environments, but this annotated example shows the idea of a payment instrument carrying information about the payer, payee, date, and amount.
Invoices, Credit Notes, and Supporting Documents
An invoice requests payment and supports an accounting entry. A credit note reduces an amount previously invoiced, for example because of a return, pricing error, discount adjustment, or service issue. A debit note can be used in some business processes to communicate an amount that should be charged or adjusted. Exact document use varies by organization and jurisdiction.

Modern systems may be electronic, but the control objective is similar to older paper systems: the transaction should be supported by evidence that explains who traded, what was supplied, the amount, and the settlement status.
| Document | Typical Use | Key Check |
|---|---|---|
| Purchase order | Authorizes a purchase | Description, quantity, price, approval |
| Goods receipt | Confirms delivery | Quantity and condition received |
| Supplier invoice | Requests payment from the buyer | Supplier, reference, amount, terms, authorization |
| Customer invoice | Requests payment from the customer | Customer, sale, amount, terms, delivery evidence |
| Credit note | Reduces a previously billed amount | Reason, authorization, original invoice reference |
| Remittance advice | Explains what a payment settles | Payer, amount, invoice references |
| Bank record | Shows movement of cash | Date, amount, payer or payee, reference |
Credit Terms, Discounts, and Due Dates
Payment terms define when an invoice is due and may include a settlement discount for early payment. For example, 2/10, n/30 commonly means that a two percent discount is available if payment is made within ten days; otherwise the full net amount is due within thirty days. Because contract wording and local practice can differ, you should read the actual terms rather than assume.
Suppose a qualifying invoice is 3,000 monetary units with terms 2/10, n/30. If the payer settles within the discount period and all conditions are met, the discount is 60 and the cash paid is 2,940. If the discount period is missed, the full 3,000 is due by the net due date.
For accounts payable, early-payment discounts can reduce purchase cost but paying too early can also use cash sooner than necessary. For accounts receivable, discounts may encourage faster collection but reduce the amount of cash collected. Decisions should follow company policy and consider liquidity, supplier or customer relationships, and the real economic benefit.
Aging Reports and Collection Priorities
An aging report groups open balances according to how long they have been outstanding. Common buckets may include current, recently overdue, moderately overdue, and long overdue balances. The exact intervals depend on the organization.
In AR, aging helps staff prioritize collection work and estimate exposure to uncollectible balances. Older unpaid receivables generally deserve more attention because collection uncertainty tends to increase as accounts remain unpaid. In AP, aging helps staff identify invoices approaching due dates, overdue supplier balances, disputed items, and near-term cash requirements.
A useful AR follow-up process is professional and evidence-based: check the invoice and due date, confirm whether the customer has a dispute, review previous contact, send a clear reminder, record the outcome, and escalate according to policy. Collection actions must comply with applicable law and company procedures.
Doubtful Accounts
Not every receivable will be collected. Under accrual accounting, organizations may use an allowance approach to estimate expected uncollectible amounts rather than waiting until a specific account finally fails. The allowance for doubtful accounts is a contra-asset that reduces gross accounts receivable to a net amount expected to be realized.
An aging-based estimate can apply different expected loss rates to groups of receivables according to age or risk. The specific accounting method required depends on the reporting framework and organization. Under IFRS 9, trade receivables can be subject to an expected-credit-loss model; under other frameworks, rules may differ.
Reconciliation and Month-End Work
Reconciliation means comparing independent or related records, investigating differences, and documenting the resolution. In AP and AR, reconciliation is not only a month-end activity; frequent reconciliation can prevent small errors from becoming larger problems.
Important reconciliations can include the AP subledger to the AP control account in the general ledger, the AR subledger to the AR control account, supplier statements to supplier accounts, customer remittance information to cash receipts, and bank records to the cash ledger.
A subledger contains detailed balances by supplier or customer. The general ledger control account contains the summarized total. If the totals do not agree, you may need to investigate timing differences, duplicate or missing postings, manual journal entries, incorrect account coding, or interface errors.
Internal Controls and Error Prevention
Internal controls help protect assets, improve the reliability of records, support efficient operations, and reduce the risk of error or fraud. No single control is enough, so organizations normally combine preventive and detective controls.
Separation of duties means that one person should not control every important stage of a transaction. For example, the person who creates a supplier should not automatically be able to approve and release payments to that supplier. The person who raises a customer credit note should not be the only person reviewing that adjustment.
Authorization means that transactions are approved by someone with the correct responsibility and limit. Documentation creates an audit trail. Access controls limit system permissions. Reconciliation detects differences after recording. Exception review focuses attention on unusual transactions such as duplicates, round amounts, changed bank details, old open items, or unexpected credits.
For AP, useful controls include invoice matching, duplicate checks, approval workflows, supplier-master controls, payment-run review, and bank-detail verification. For AR, useful controls include customer credit approval, controlled credit-note authorization, sequential invoice controls, daily cash application, overdue review, and reconciliation of the AR subledger.
Professional Communication
AP and AR staff communicate with purchasing, receiving, sales, customer service, treasury, suppliers, and customers. Good communication is clear, factual, respectful, and traceable.
When querying a supplier invoice, state the invoice number, purchase-order reference, the exact mismatch, and the action needed. When reminding a customer about an overdue balance, state the invoice number, due date, amount, and how to provide payment or dispute information. Avoid accusing a supplier or customer before the facts have been checked.
A useful workplace note should answer four questions: what happened, what evidence was checked, what action is required, and who owns the next step.
Worked Case Study: Northstar Workshop
Northstar Workshop is a fictional training company. On 3 March, it buys equipment maintenance services for 2,400 monetary units on thirty-day credit. The approved supplier invoice creates a liability. The entry is a debit to Maintenance Expense and a credit to Accounts Payable for 2,400. When Northstar pays the supplier, Accounts Payable is debited and Cash or Bank is credited.
On 8 March, Northstar provides repair services to a business customer for 3,600 monetary units and allows the customer thirty days to pay. The credit sale creates Accounts Receivable of 3,600 and Service Revenue of 3,600. On 25 March, the customer pays 1,400. Cash increases by 1,400 and Accounts Receivable decreases by 1,400, leaving 2,200 outstanding.
At month-end, the AP clerk should confirm that the 2,400 supplier balance agrees with the AP subledger, supporting invoice, and supplier statement where available. The AR clerk should confirm that the customer's remaining 2,200 balance agrees with the invoice and the partial payment. If the customer payment was posted to the wrong invoice, the total cash may still be correct while the customer detail is wrong, so reconciliation is essential.
Performance Measures and Working Capital
AP and AR influence Working capital and Cash flow. High receivables can mean that a large amount of sales has not yet turned into cash. High payables can preserve cash temporarily but may also signal late payment, disputes, or strained supplier relationships.
The accounts receivable turnover ratio is commonly calculated as net credit sales divided by average accounts receivable. A related measure, often called days sales outstanding, can be approximated as days in the period divided by receivables turnover. These measures help you study collection speed, but they should be interpreted with credit terms, seasonality, customer mix, and business changes.
The accounts payable turnover ratio is commonly based on credit purchases or another policy-defined purchasing measure divided by average accounts payable. A related days-payable measure can estimate how long the organization takes to pay suppliers. Because published formulas can vary when credit-purchase data is unavailable, you should use the definition required by your organization or course.
Operational decisions should not focus on one ratio alone. Collecting earlier may improve cash flow, while paying suppliers according to agreed terms can protect supplier relationships and preserve access to goods, services, and discounts.
Digital Accounting and E-Invoicing
Modern AP and AR processes may use Enterprise resource planning systems, cloud accounting, e-invoicing, document capture, workflow approvals, bank feeds, automated matching, and exception dashboards. Automation can reduce repetitive data entry, but it also creates new control needs.
You should understand which data is captured automatically, which fields require review, how duplicate detection works, who can change master data, what approvals are required, and how exceptions are documented. Never assume that an automated match is correct just because a system accepted it. Staff should understand the underlying business transaction and investigate unusual items.
Digital records should be stored according to company policy and applicable law. Personal data, bank details, and commercially sensitive information should only be accessed and shared for legitimate work purposes.
