The money left, but you haven't bought anything yet

You wire a supplier a two-thousand-dollar deposit on a custom order that won't ship for six weeks. Cash left your account, so the instinct is to book it as an expense. That instinct is wrong — and it's the mirror image of the mistake owners make with customer deposits. When a customer prepays you, the money isn't your revenue yet; it's a liability, because you owe them something. When you prepay a supplier, the money isn't your expense yet; it's an asset, because the supplier now owes you goods or services. Recording it as an expense on the day you pay overstates your costs, understates your assets, and throws off both your profit and loss and your balance sheet. (General education, not accounting advice.)

Why a prepayment is an asset, not an expense

The clean way to think about it: an expense is recognized when you receive and consume the good or service, not when cash moves. On the day you send a deposit, you haven't received anything — you've swapped one asset (cash) for another (a claim on the supplier). That claim is called a vendor deposit, supplier prepayment, or prepaid to vendor, and it lives as a current asset on your balance sheet, much like a prepaid expense.

This matters because it keeps your books honest in both directions. Your cash goes down (true — the money's gone), but your total assets don't, because the prepayment replaces it. And your expenses don't spike in the month you paid the deposit, so your P&L reflects the month you actually receive the goods, not the month you happened to fund the order.

Recording it: two steps, weeks apart

The lifecycle has two moments:

When you pay the deposit. Record the payment against a Vendor Deposits (or prepaid-to-supplier) asset account — not to an expense category. Cash goes down; the vendor-deposit asset goes up by the same amount. Nothing hits your P&L. Note which supplier and which order it relates to, because you'll need to match it later.
When the bill arrives. The supplier delivers and sends the full bill. Now you record the vendor bill as the actual expense (or inventory) at its full amount — and you apply the deposit you already paid against it. The remaining balance is what you still owe. The deposit asset is now cleared to zero, because the claim it represented has been fulfilled.

That second step is the one people forget. If you record the deposit as an asset but then book the full bill as a new expense without clearing the deposit, you'll double-count: the deposit asset sits on your balance sheet forever, and your expense is overstated by the deposit amount.

A quick worked example

You order custom equipment for five thousand dollars and pay a two-thousand-dollar deposit up front. Six weeks later it's delivered with a bill for the full five thousand.

Day of deposit: cash down two thousand; Vendor Deposits asset up two thousand. No expense. Your books show you're two thousand lighter in cash but hold a two-thousand claim on the supplier.
Day the bill arrives: record the five-thousand equipment purchase, apply the two-thousand deposit against it, leaving three thousand as an open payable you still owe. The deposit asset clears to zero.
Net result: total recorded cost is exactly five thousand — the real price — recognized when you received the equipment, and you paid it as two thousand early plus three thousand at delivery. No double-counting, no phantom asset left behind.

Watch the timing and the trail

A stray, uncleared vendor deposit is exactly the kind of stale asset a month-end close is meant to catch — an old prepayment that was really consumed months ago but never matched to its bill. Review the vendor-deposits account periodically and make sure each open balance still represents a supplier who genuinely owes you something. And if a deal falls through and the supplier refunds you, that's cash back in and the deposit asset cleared — not income.

Hosting Books lets you record a payment to a supplier as a prepayment and apply it against the bill when it arrives, so the deposit lands on your balance sheet as an asset and clears cleanly when the goods show up — instead of hiding in an expense category the day you funded the order.

Three-Way Matching: Tying the Purchase Order, the Receipt, and the Vendor Invoice
A vendor invoice on its own is just a request for money. Three-way matching is the control that answers three questions before you pay it: did we agree to buy this, did we actually receive it, and is the bill for the right amount? Here is how the PO, the receiving record, and the invoice line up — and how a disciplined match stops overbilling, duplicate payments, and phantom charges before the money leaves.
