What it means
In standard business accounting, expenses are typically recorded when an invoice arrives or when payment is made. However, this leaves a dangerous gap between ordering something and paying for it, during which time you might accidentally spend the same money twice.
Encumbrance accounting solves this problem by introducing a holding stage. When you commit to a purchase, such as signing a contract or issuing a purchase order, you create an encumbrance.
This action sets the money aside mentally and in your ledger, reducing your available balance immediately, even though the cash has not left your bank account yet. This practice is especially vital for organizations with strict budgets, such as government agencies, non-profits, and larger small businesses.
Without encumbrance accounting, managers look at their financial reports and see a large pool of available cash, unaware that several big orders are already in transit. By recognizing committed funds early, decision-makers get a realistic view of their true financial standing.
It stops departments from making competing purchases that exceed their allocated limits. In practice, the lifecycle of a transaction under this system has three main steps.
First, you create the encumbrance when placing an order. Second, you liquidate that encumbrance and turn it into an actual account payable when the goods arrive and you receive the invoice.
Third, you clear that payable when the final payment is sent. This careful tracking ensures total visibility over every pound or dollar, giving business owners peace of mind and preventing nasty end-of-month budget surprises.
In practice
Real-world examples.
Example
A digital marketing agency issues a purchase order for five new laptops costing one thousand pounds each. Encumbrance accounting immediately earmarks five thousand pounds so that money cannot be spent elsewhere.
Example
A small manufacturing firm signs a contract for raw materials valued at twelve thousand pounds. The finance team logs an encumbrance to protect those funds until the delivery and invoice arrive next month.
Example
A local charity commits three thousand pounds to sponsor a community event venue. Encumbrance accounting reserves the funds immediately, preventing project leads from accidentally allocating them to catering.
Think of it
“Imagine reserving a table at a busy restaurant by putting down a deposit. That table is now off-limits to other walk-in customers, even though you have not ordered your meal yet. Encumbrance accounting works the same way for your business budget.
Formula
Calculation
Available Budget = Total Budget - (Actual Expenses + Encumbrances)
Example: If your department has a total budget of fifty thousand pounds, has spent twenty thousand pounds on actual invoices, and holds ten thousand pounds in active purchase orders (encumbrances), your calculation looks like this:
Available Budget = fifty thousand - (twenty thousand + ten thousand)
Available Budget = fifty thousand - thirty thousand = twenty thousand pounds remaining.Case study
Seen in the real world.
Oakwood Community Centre operated with a tight annual budget of one hundred thousand pounds. Historically, managers struggled with accidental overspending because they only tracked money when bills were paid. Halfway through the year, the centre manager approved a major playground repair estimated at forty thousand pounds, issuing a formal purchase order. Unaware that this money was now mentally spoken for, another department lead used remaining visible funds to buy twenty thousand pounds of new office furniture.
When the playground invoice arrived for thirty-eight thousand pounds, Oakwood suddenly faced a severe cash flow crisis. The combined commitments exceeded their total budget by eight thousand pounds, forcing them to scramble for emergency funding.
To fix this, Oakwood adopted encumbrance accounting. The following year, when the playground repair purchase order was issued, forty thousand pounds was instantly locked as an encumbrance. When the office furniture request came in later, the software flagged that only sixty thousand pounds remained uncommitted, and the furniture order was paused until budget adjustments could be made. This simple shift eliminated end-of-year budget deficits entirely.
Watch out
Common mistakes.
- Treating encumbrances as actual cash payments rather than reserved commitments.
- Failing to release or reverse encumbrance amounts when a supplier cancels an order.
- Forgetting to include encumbrances when calculating available departmental spending limits.
Questions
People also ask.
Is encumbrance accounting only for government organizations?
No. While public sector bodies and non-profits use it heavily due to strict regulations, any business wanting tight control over purchase commitments can benefit.
Does an encumbrance reduce my bank account balance?
No. It only reduces your available budget in your internal accounting records. Your actual bank balance remains unchanged until the bill is paid.
What happens to an encumbrance when the invoice arrives?
The encumbrance is reversed or liquidated, and the amount is converted into a standard accounts payable entry for final payment processing.
