Accounts payable

Accounts payable is a file or account that contains money that a person or company owes to suppliers, but has not paid yet (a form of debt). When you receive an invoice you add it to the file, and then you remove it when you pay. Thus, the A/P is a form of credit that suppliers offer to their purchasers by allowing them to pay for a product or service after it has already been received.

The profession is unregulated, though there are international standard setting bodies, an example of which is the International Accounts Payable Professionals (IAPP), an association of more than 5,000 members in the United States, Canada, the United Kingdom and other countries. As part of its Professional Standards Framework,the IAPP has established a new definition of accounts payable:

Accounts payable is a strategic, value-added accounting function that performs the primary non-payroll disbursement functions in an organization. As such, the AP operation plays a critical role in the financial cycle of the organization. AP enables an organization to accomplish its objectives by bringing a systematic, disciplined approach to evaluate and improve the effectiveness of the entire payables process. In addition to the traditional AP activities whereby liabilities to third-party entities (suppliers, vendors, taxing authorities, etc.) are recognized and paid based on the credit policies agreed to between the company and its suppliers, today's AP departments have taken on much wider roles including fraud prevention, cost reduction, workflow system solutions, cash-flow management, internal controls and vendor (supply chain) financing.

In households, accounts payable are ordinarily bills from the electric company, telephone company, cable television or satellite dish service, newspaper subscription, and other such regular services. Householders usually track and pay on a monthly basis by hand using cheques or credit cards. In a business, there is usually a much broader range of services in the A/P file, and accountants or bookkeepers usually use accounting software to track the flow of money into this liability account when they receive invoices and out of it when they make payments. Increasingly, large firms are using specialized Accounts Payable Automation to automate the paper and manual elements of processing an organization's invoices.

Commonly, a supplier will ship a product, issue an invoice, and collect payment later, which creates a cash conversion cycle, a period of time during which the supplier has already paid for raw materials but hasn't been paid in return by the final customer.

When the invoice arrives it is matched to the packing slip and purchase order, and if all is in order, the invoice is paid. This is referred to as the three-way match.

Expense administration

Expense administration is usually closely related to accounts payable, and sometimes those functions are performed by the same employee. The expense administrator verifies employees' expense reports, confirming that receipts exist to support airline, ground transportation, meals and entertainment, telephone, hotel, and other expenses. This documentation is necessary for tax purposes and to prevent reimbursement of inappropriate or erroneous expenses. Airline expenses are, perhaps, the most prone to fraud because of the high cost of air travel and the confusing nature of airline-related documentation, which can consist of an array of reservations, receipts, and actual tickets.

Internal controls

A variety of checks against abuse are usually present to prevent embezzlement by accounts payable personnel. Separation of duties is a common control. Nearly all companies have a junior employee process and print a cheque and a senior employee review and sign the cheque. Often, the accounting software will limit each employee to performing only the functions assigned to them, so that there is no way any one employee – even the controller – can singlehandedly make a payment.

Some companies also separate the functions of adding new vendors and entering vouchers. This makes it impossible for an employee to add himself as a vendor and then cut a cheque to himself without colluding with another employee. This file is referred to as the master vendor file. It is the repository of all significant information about the company's suppliers. It is the reference point for accounts payable when it comes to paying invoices.

In addition, most companies require a second signature on cheques whose amount exceeds a specified threshold.

Accounts payable personnel must watch for fraudulent invoices. In the absence of a purchase order system, the first line of defense is the approving manager. However, A/P staff should become familiar with a few common problems, such as "Yellow Pages" ripoffs in which fraudulent operators offer to place an advertisement. The walking-fingers logo has never been trademarked, and there are many different Yellow Pages-style directories, most of which have a small distribution. According to an article in the Winter 2000 American Payroll Association's Employer Practices, "Vendors may send documents that look like invoices but in small print they state "this is not a bill." These may be charges for directory listings or advertisements. Recently, some companies have begun sending what appears to be a rebate or refund check; in reality, it is a registration for services that is activated when the document is returned with a signature."

In accounts payable, a simple mistake can cause a large overpayment. A common example involves duplicate invoices. An invoice may be temporarily misplaced or still in the approval status when the vendors calls to inquire into its payment status. After the A/P staff member looks it up and finds it has not been paid, the vendor sends a duplicate invoice; meanwhile the original invoice shows up and gets paid. Then the duplicate invoice arrives and inadvertently gets paid as well, perhaps under a slightly different invoice number.

Audits of accounts payable

Auditors often focus on the existence of approved invoices, expense reports, and other supporting documentation to support checks that were cut. The presence of a confirmation or statement from the supplier is reasonable proof of the existence of the account. It is not uncommon for some of this documentation to be lost or misfiled by the time the audit rolls around. An auditor may decide to expand the sample size in such situations.

Auditors typically prepare an ageing structure of accounts payable for a better understanding of outstanding debts over certain periods (30, 60, 90 days, etc). Such structures are helpful in the correct presentation of the balance sheet as of year end.
