Early-payment discount or finance cost: which is bigger in dollars?

The email arrives mid-afternoon: pay the full invoice by 5pm tomorrow and take a healthy chunk off, or pay the usual amount in 30 days. Or it’s the other version — prices go up on the first of the month, and anything ordered and paid before then is locked in at today’s price. Either way, there’s real money on the table and a clock running.

The instinct is to grab it. The better move is to spend fifteen minutes on the maths and the timeline first. Sometimes fast funding turns a good deal into a great one. Sometimes the finance quietly eats the saving. Here’s how to tell the difference, and how to move fast if the numbers stack up.

Why do suppliers offer early-payment discounts at all?

Because cash in hand is worth more to them than cash in 30 or 60 days. business.gov.au lists early-payment discounts among the standard tools for improving a business’s cash flow, alongside deposits and late fees. When a supplier offers you one, they’re paying you to fix their cash flow. The question is whether it’s cheaper for you to borrow the money than for them to wait for it.

Price-rise deadlines work differently but land in the same place: the supplier is giving you a window to buy at the old price, and the saving only exists if you can pay inside it.

How do you compare the discount with the cost of finance?

In dollars. Percentages on invoices and loans measure different things over different periods, and mixing them up is how owners talk themselves into bad trades. Put both sides in plain dollar terms.

Side one — the saving:

• The dollar amount the supplier takes off, or the dollar difference between the old and new price.
• Only on stock or services you would genuinely buy anyway, in a sensible time frame.
• Minus any extra costs of buying early — storage, insurance, handling, the risk of the stock ageing.

Side two — the total cost of finance:

• Everything you’ll pay beyond the amount borrowed, for the period you’ll actually have the loan.
• Establishment, legal, valuation and other fees, not just the ongoing cost.
• Any costs of repaying early if the stock sells faster than expected.

Ask any lender for the total cost in dollars for your expected term. If they can’t give you a clear number, that’s a reason to pause.

Illustrative example: when the numbers work, and when they don’t

The figures below are illustrative only. They’re not from a real client and don’t represent any particular lender’s pricing.

A wholesaler receives a $180,000 invoice for a bulk order of stock it sells steadily. The supplier offers $5,400 off for payment within two business days. The wholesaler expects to sell through the stock and receive customer payments within about six weeks.

	Scenario A	Scenario B
Saving from paying early	$5,400	$5,400
Total cost of finance for about six weeks, including fees	$3,100	$6,200
Extra storage or handling costs	$0	$0
Net result	$2,300 better off	$800 worse off

Same discount, same order. The only difference is the total cost of the funding — which is why that dollar figure is the number to get before anything else. In Scenario B, the smarter move is to ask the supplier for a partial discount on a partial early payment, or to let the discount go.

Notice what isn’t in the table: a percentage. You don’t need one to make the decision.

When is fast funding clearly not worth it?

• The stock isn’t a sure seller. A discount on something that sits in the warehouse for six months isn’t a saving.
• The finance period will run long. If you’re not confident when the cash comes back, the cost side grows while the saving stays fixed.
• You’d be stretching other commitments. If the extra repayment would squeeze wages, tax or rent, the risk outweighs the reward.
• It’s the second or third “deal” this quarter. Borrowing to chase every discount can become a habit that costs more than it saves.

How do you work backwards from the supplier’s deadline?

If the numbers work, the next question is whether the money can actually arrive in time. Start with the supplier’s exact deadline — date, time and their time zone — and work backwards.

1. When must the money land? Allow a margin for the supplier’s bank to show the payment.
2. Which kind of funding fits? Smaller unsecured amounts can be funded the same day in the right conditions. Property-secured loans from $20k to $250k are possible the same day, and up to $5m is possible within 24–48 hours.
3. What’s the business-day calendar? Property settlements only happen on business days. A deadline on a Monday effectively means Friday for a property-secured loan.
4. Is your paperwork ready? Bank statements, ID, ATO position, property details — every missing item costs time. The Paperwork Stopwatch ranks your gaps.
5. Who needs to sign? Line up every director and guarantor for the afternoon.

The 24-Hour Funding Clock does this maths for you: enter your enquiry time, state, security and paperwork, and it shows the earliest realistic funding window against the deadline. If it’s tight, the quickest step is to start a 60-second enquiry so a real person can plan backwards from the supplier’s cut-off with you.

Can the supplier be paid directly?

Often, yes, and on a deadline it’s usually the best way. Loan documents can direct funds straight to the supplier’s account, which means:

• no second transfer from your account, and no daily transfer limit to worry about;
• the supplier gets payment from the lender with a clear reference;
• you avoid a gap between funds landing with you and leaving for them.

You’ll need the supplier’s exact account details and the invoice. Payments sent over Australia’s New Payments Platform can reach the recipient in near real time, around the clock, although whether a particular payment goes that way depends on the lender and the banks involved. Read when funds land for how the final step works.

What should you ask the supplier before you borrow?

A two-minute call can change the maths:

• Can the discount window stretch a day or two? Many suppliers will extend it for a reliable customer who can show funding is underway.
• Is a partial early payment possible for a partial discount? Paying half early might capture most of the benefit with less borrowing.
• Would a deposit lock in the old price? On price-rise deadlines, a deposit sometimes secures the order.
• What are the exact payment details and cut-off time? Get them in writing.

What if the cash comes from somewhere other than a loan?

Sometimes the fastest money isn’t borrowed. Chasing a large overdue debtor, drawing on an existing line of credit, or using a cash buffer you’ve been holding for exactly this can all fund a discount. The guide to raising business cash fast ranks the options by how long each typically takes.

Ready to check whether the deal stacks up?

A good supplier deal is worth a few minutes of maths and a quick conversation with someone who can tell you the real cost and the real timeline. If the numbers work, you’ll want to be moving before the deadline gets tight. Enquiring takes about 60 seconds and there’s no credit check when you first enquire. Your details go to one team rather than being sprayed across a list of lenders, so your phone won’t ring off the hook. A real person looks at the invoice, the deadline and your security, and tells you plainly what’s possible. Please fill in the form accurately — especially the amount and the date the supplier needs paying — so you’re matched with the right option first time.
