Federal Accounting Dictionary – Accounts Payable

Accounts payable is where the government admits it owes somebody money. The goods arrived, the contractor hit the milestone, the rent came due, and the check has not gone out yet. It is a proprietary accounting term, not a budget term, and that single distinction causes more confusion than almost anything else in federal accounting.

Plain-English Definition

Accounts payable is what your agency owes right now for things it has already received. Think of it like this: an obligation is the promise to buy. Accounts payable is the bill on your desk after the thing showed up. The outlay is the moment you actually pay it.

Official Definition

According to the GAO's Federal Budget Glossary, Accounts Payable is defined as: "Amounts owed by a federal agency for goods and services received from, progress in contract performance made by, and rents due to other entities. This is a proprietary (or financial) accounting term."

FASAB says the same thing in the accounting standards. SFFAS No. 1, paragraph 74:
"Accounts payable are amounts owed by a federal entity for goods and services received from, progress in contract performance made by, and rents due to other entities."

SFFAS No. 1, paragraph 77 supplies the recognition trigger: "When an entity accepts title to goods, whether the goods are delivered or in transit, the entity should recognize a liability for the unpaid amount of the goods."

USSGL Accounts

Account Title: Accounts Payable 
Account Number: 211000
Normal Balance: Credit
Definition: This account is used to record the amount owed to another federal entity, or non-federal entity for goods and other property ordered and received, and for services rendered by other than employees. This account does not close at year-end.

The budgetary counterpart is USSGL 490100, Delivered Orders - Obligations, Unpaid. Proprietary and budgetary entries move together when goods are received.

What This Means in Practice

  • Receipt of title is the trigger, not receipt of the invoice. Once your agency accepts title or the service is performed, the liability exists. Waiting for a vendor invoice understates liabilities and is one of the most common completeness findings in federal audits.
  • Every payable has a budgetary twin. When you record the proprietary payable in 211000, the budgetary side moves from undelivered orders to delivered orders - obligations, unpaid (490100). If one side moves and the other does not, you have a reconciliation problem to run down.
  • Year-end accrual estimates are a control area, not a math exercise. Estimated payables at September 30 are among the highest-risk estimates in the federal close. OMB Circular A-123 expects documented, tested controls over how those estimates are built and reviewed.
  • Payables are where improper payments start. Paying a payable twice, or paying one that should never have been recorded, is the mechanism behind a large share of improper payments. Controls over the three-way match live here.
  • Intragovernmental payables must agree with the trading partner. Your payable to another agency should equal that agency's receivable from you. Differences roll up into the intragovernmental elimination problems flagged every year in the government-wide audit.

Simple Example

Scenario: Your agency accepts delivery of $500,000 in laptops on September 20 under a contract obligated back in July. The vendor invoice arrives October 12. Payment goes out October 25.

  1. July. Contract signed. Record the obligation. Budgetary only, as an undelivered order. No payable yet, because nothing has been received.
  2. September 20. Title accepted. Record $500,000 in accounts payable (211000) and move the budgetary entry from undelivered orders to delivered orders - obligations, unpaid (490100). The expense belongs to this fiscal year.
  3. October 25. Payment issued. The payable clears and the outlay is recorded in the new fiscal year.

The expense lands in the year the laptops arrived. The outlay lands in the year the check cleared. Both are correct, and they sit in different fiscal years. That gap is normal, and explaining it is half of what a federal accountant does in October.

Common Mistakes or Confusion

Obligation vs. Accounts Payable vs. Expense vs. Outlay

Obligation: the legal commitment created when you sign the contract or issue the order. Budgetary. Nothing has been received yet.

Accounts Payable: the liability created when the goods or services are actually received. Proprietary.

Expense: the cost recognized when the resource is consumed. Often the same moment as the payable, but not always, as with prepaid items.

Outlay: cash leaving Treasury. Usually the last step.

  • Treating "no invoice yet" as "no liability yet." The standard keys on receipt, not paperwork.
  • Assuming accounts payable should tie exactly to delivered orders - obligations, unpaid. It usually will not, because some liabilities sit in other accounts, such as accrued payroll in 221000.
  • Recording a payable for goods still in transit under FOB destination terms. Title has not passed, so there is no liability yet.


If you only remember one thing: An obligation says "we agreed to buy it." A payable says "we got it and we haven't paid yet."

Where You’ll See This Term Used

You will see accounts payable on the balance sheet under liabilities (OMB Circular A-136 reporting requirements), in the reconciliation between the Statement of Budgetary Resources and the proprietary statements, in year-end accrual workpapers, in the intragovernmental reconciliation with trading partners, and in audit sample selections testing the completeness of liabilities. TFM Part 2, Section V crosswalks USSGL 211000 to the balance sheet line.
