No account is debited when a purchase order is created under standard accrual-basis accounting. A PO is a commitment to buy, not a completed transaction, so it produces no journal entry on either the balance sheet or the income statement. The debit most people associate with a purchase — to inventory, an expense, or a fixed asset — is recorded later, once the vendor actually delivers. The main exception is government encumbrance accounting, where issuing a PO does trigger a budgetary entry.
Why the PO Itself Produces No Journal Entry
A purchase order is an executory contract. When you send it to a vendor, neither side has performed: the vendor has not shipped, and you have not paid. Because no economic resource has changed hands, there is nothing to record. Booking a debit at this stage would overstate your assets or expenses and create a liability that does not yet exist.
This follows a basic recognition principle. Financial statements should reflect events that have already happened, not events that might happen. A PO can still be canceled, modified, or only partially filled, so treating it as a completed exchange would distort your financial position. Until the vendor performs, the PO lives in your procurement system as an administrative record and nothing more.
The same logic covers the purchase requisition — the internal approval form an employee submits before a PO is issued. A requisition is even further from a completed transaction than a PO, so it produces no accounting entry either.
The Government Exception: Encumbrance Accounting
Government agencies operate under legally adopted budgets, and their spending is capped by those appropriations. To prevent overspending, many agencies use encumbrance accounting, which reserves budget dollars the moment a PO is issued. This is the one common scenario where creating a purchase order does generate an accounting entry.
When a government agency issues a PO, it debits an Encumbrances account and credits a reserve account, often called Reserve for Encumbrances or Budgetary Fund Balance Reserved for Encumbrances. The entry sits in the budgetary accounts rather than on the full accrual financial statements. Its purpose is to show that a portion of the appropriation is already spoken for, so administrators can see exactly how much of the budget remains available.
Once the goods or services arrive, the encumbrance entry is reversed — debit the reserve account, credit Encumbrances — and a standard expenditure entry is recorded in its place. The Governmental Accounting Standards Board sets the reporting standards state and local governments follow, including how budgetary information is presented.
If the fiscal year closes before the PO is fulfilled, the encumbrance does not disappear. Agencies typically carry the encumbered amount forward into the next year’s appropriation so the commitment is honored. If the order is later canceled, the reserved funds return to unappropriated fund balance rather than becoming available for other spending.
When a Deposit or Prepayment Is Sent With the Order
If you send money to the vendor at the time you place the order, that payment does trigger a journal entry, even though nothing has been delivered yet. The typical entry debits a prepaid asset account — sometimes labeled Advance to Supplier or Vendor Prepayments — and credits cash or your bank account. The debit sits on your balance sheet as an asset because you now have a right to receive goods or a refund.
Once the vendor delivers, you reclassify the prepaid amount. The prepaid asset account is credited to zero it out, and the appropriate asset or expense account (Inventory, Supplies Expense, and so on) is debited for the value of what you received. If the delivery only covers part of the prepayment, the remaining balance stays in the prepaid account until the rest arrives or you negotiate a refund.
What Actually Gets Debited After Delivery
The journal entry everyone associates with a purchase happens after the vendor ships and you confirm receipt. At that point the transaction is no longer executory, and the vendor has earned the right to payment. Which account you debit depends on what you bought:
- Goods you plan to resell or use in manufacturing are debited to an Inventory account, a current asset on the balance sheet.
- Office supplies, utilities, or services consumed immediately are debited to the relevant expense account, such as Supplies Expense or Repairs Expense, which reduces net income.
- Equipment, furniture, or other long-lived items are debited to a fixed asset account like Equipment or Machinery, then depreciated over their useful life.
In every case, the offsetting credit goes to Accounts Payable, reflecting the amount you now owe the vendor. Receiving $10,000 of equipment, for instance, produces a $10,000 debit to Equipment and a $10,000 credit to Accounts Payable. When you later pay the invoice, you debit Accounts Payable and credit Cash to close out the liability.
Partial Shipments
Vendors do not always deliver everything at once. When you receive a partial shipment, you record only the portion that arrived. If a $5,000 PO is filled in two shipments of $3,000 and $2,000, each delivery generates its own journal entry for the amount received. The PO stays open in the procurement system until the full quantity is delivered or the remainder is canceled. Each partial entry follows the same debit-to-asset-or-expense, credit-to-Accounts-Payable pattern.
Year-End Accruals for Open Purchase Orders
If you use accrual-basis accounting and your fiscal year ends with a PO still open, you may need an adjusting entry. The key question is whether goods or services were received before year-end even though the invoice has not yet arrived.
- Goods received, no invoice yet: debit the asset or expense account and credit Accrued Liabilities (or Accounts Payable) for the estimated amount, so the expense lands in the correct fiscal year.
- Deposit paid, goods not received: the deposit remains classified as a prepaid asset on the balance sheet. No expense is recorded because you have not yet benefited from the goods.
- Nothing received, nothing paid: no accrual is necessary. The PO is simply an open commitment carried into the next period.
When the actual invoice arrives in the new year, any accrual entry is reversed and replaced with the final recorded amount. That reversal-and-replacement keeps both fiscal years accurate without double-counting the expense.
The short version: at the moment a purchase order is created, the answer for a private business is no debit at all, for a government agency it is the Encumbrances account against a budgetary reserve, and for a buyer who prepays it is a prepaid asset against cash. The familiar debit to inventory, expense, or a fixed asset waits until the vendor delivers.
