What it means
A money order works like a cheque that has already cleared. You hand over cash or a card payment at a post office, bank or retailer, and they issue a document promising to pay that exact amount to whoever you name on it.
The appeal for a business is certainty of funds. A supplier who accepts a money order knows the money already exists, because the issuer collected it before printing the instrument, so there is no risk of the payment being reversed for insufficient funds.
Limits are the main practical constraint. Most issuers cap a single money order at somewhere between a few hundred and a thousand dollars, so a larger payment needs several orders and several fees, which quickly becomes clumsy and expensive.
In cash flow terms, a money order leaves your account the moment you buy it rather than when the recipient banks it. That matters for forecasting, because the outflow is immediate and effectively irreversible, unlike a posted cheque that may sit uncashed in a drawer for weeks.
Money orders remain common for rent, small trade payments and remittances, and for anyone without a bank account. The trade-off is cost and friction, since per-transaction fees and manual handling make them poor value for anything you do repeatedly.
In practice
Real-world examples.
Example
A tenant without a current account pays $1,200 of monthly rent using two money orders, because the issuer caps each one at $1,000. The letting agent accepts them because the funds are guaranteed and cannot later be reversed.
Example
A used equipment dealer sells a $900 compressor to a buyer he has never met. He asks for a money order rather than a personal cheque, deposits it the same afternoon and releases the machine only once his bank confirms receipt.
Example
A charity running a rural literacy project sends $500 grants to volunteers in areas with limited banking. Money orders let recipients collect cash at a local post office without needing to open an account first.
Formula
Calculation
Total cost = face value + issuing fee, and effective fee rate = issuing fee / face value
A small landscaping business pays a parts supplier $700 by money order and the post office charges a $2.35 issuing fee. The total cost is $700 + $2.35 = $702.35, and the effective fee rate is $2.35 / $700 = 0.34%. If the business makes that payment every month for a year, the face value totals 12 x $700 = $8,400 and the fees total 12 x $2.35 = $28.20, for an all-in cost of $8,428.20. Switching the same twelve payments to bank transfers at $0.50 each would cost 12 x $0.50 = $6.00, saving $28.20 - $6.00 = $22.20 a year plus a monthly trip to the counter.Case study
Seen in the real world.
Redstone Plumbing Supplies is an invented company used here as an illustrative example of a business that leaned on money orders for too long. It bought stock from a handful of small fabricators who had been burned by bounced cheques, so it settled roughly forty invoices a month by money order at an average $2.80 fee.
That worked out at about 40 x $2.80 = $112 a month, or $1,344 a year, before counting the staff time spent queueing and the occasional order that went missing in the post. The owner regarded the fee as trivial and never questioned it.
When a new bookkeeper reviewed payment methods, she offered the suppliers a same-day electronic transfer with a payment confirmation attached to each remittance. Thirty of the forty suppliers switched within a quarter, and the illustrative point is that the real cost was never the fee, it was the hours and the delay that nobody had itemised.
Watch out
Common mistakes.
- Assuming a money order is untraceable, when the issuer keeps a record and can usually confirm whether it has been cashed and by whom.
- Throwing away the receipt stub, which is the only practical way to trace or replace a lost money order.
- Accepting a money order for a high-value sale without verifying it with the issuer, since counterfeit money orders are a well-known fraud in classified-advert sales.
Questions
People also ask.
Can a money order be cancelled?
Yes, but only if it has not yet been cashed, and the issuer will normally charge a cancellation fee and take several weeks to refund you.
How is a money order different from a cashier's cheque?
A cashier's cheque is drawn on a bank's own funds and typically has no upper limit, while a money order is issued by post offices and retailers as well as banks and is capped at a small amount.
Does receiving a money order still count as revenue?
Yes, revenue is recognised when you earn it under accrual accounting, and the money order is simply the settlement method for cash that has already been committed.
