Quick answer
Buy ahead of a supplier price increase when the rise is confirmed in writing, you'll use or sell the extra stock within a reasonable time, and the saving is larger than the combined cost of holding it and funding it. Don't buy ahead when the stock could spoil, date or sit for months, when storage is tight, or when the purchase would drain cash needed for wages and tax.
Key points
- Only act on a confirmed, dated increase — not a rumour.
- Saving = extra quantity × price difference.
- Subtract holding costs and the dollar cost of funding the extra stock.
- Buy only what you'll sell or use in a reasonable time.
The email arrives with a polite subject line: “Important update to our pricing”. From a date a few weeks away, what you pay goes up. The question every owner asks next is whether to stock up before it does. Sometimes that’s a smart move. Sometimes it swaps a small price rise for a bigger cash-flow problem.
Is the increase real and dated?
Before doing any maths, check what you’ve actually been told:
- Is there a specific percentage or new price list?
- Is there a specific effective date?
- Does it apply to all lines or only some?
- Is there any grace period for orders placed before the date but delivered after?
A confirmed, dated increase is worth planning around. Vague warnings about “cost pressures” usually aren’t enough to justify a big forward buy. That said, prices overall have been moving: the ABS reported the CPI rose 4.0% in the 12 months to August 2026, so notices are more common than they were a few years ago.
How do I calculate whether buying ahead is worth it?
Use a simple four-line test:
| Line | How to work it out |
|---|---|
| A. Gross saving | Extra quantity bought now × (new price − current price) |
| B. Holding cost | Storage, insurance, spoilage or obsolescence risk over the holding period |
| C. Finance cost | Total dollar cost of funding the extra stock, if you borrow |
| D. Net saving | A − B − C |
If D is comfortably positive, buying ahead makes sense. If D is small or negative, don’t. If you’re paying from cash, still count C as the value of what else that cash could have done — wages, super, a BAS payment, or another opportunity.
How much should I buy ahead?
Only what you’ll realistically sell or use within a sensible window — often one to three months for most goods. Past that, three things happen:
- the stock takes up space you need for other lines;
- the risk of it dating, spoiling or becoming obsolete grows;
- the cash tied up in it can’t cover other costs.
business.gov.au lists keeping stock levels from running too high as one way to protect cash flow. A forward buy should be sized to the saving, not to the size of the warehouse.
Illustrative example: the tile and bathroom supplier
Illustrative only — invented figures.
A bathroom renovation business receives notice that its main tile supplier will lift prices by 8% from 1 August. It normally buys about $22,000 of tiles a month and has three months of booked jobs.
- A. Buying three months’ tiles now: $66,000 × 8% ≈ $5,280 gross saving.
- B. Storage in its existing warehouse is covered; breakage risk is low. Allow $400.
- C. A short-term facility for $66,000, repaid over the three months as jobs are invoiced, costs a total that’s well under the saving.
- D. Net saving: clearly positive — and the jobs are already booked, so the stock will move.
Had the supplier been a food distributor with a short shelf life, or had the jobs not been booked, the answer would change. If you’re looking at a notice like this, check what’s possible before the date passes.
What else can I do instead of buying ahead?
- Negotiate. Ask whether a forward order at today’s price can be delivered in stages.
- Review your own prices. If your costs are rising, your prices may need to follow.
- Compare suppliers. A price notice is a good moment to check the market.
- Adjust your range. Some lines may no longer earn their shelf space at the new price.

How do I respond to the supplier?
A price notice is the start of a conversation, not the end. A short, polite reply can uncover options:
- Ask for the reason. Understanding whether it’s freight, wages or raw materials helps you judge whether it might reverse.
- Ask about a forward order. Will they hold the current price for a committed volume, delivered in stages?
- Ask about terms. Longer payment terms can offset part of an increase.
- Ask about alternatives. A different pack size, grade or brand may avoid the rise.
Keep the reply factual and friendly. Suppliers generally value reliable customers who pay on time; that relationship is often worth more than the increase itself. And if paying on time is becoming the challenge, read the cost of paying bills late — or for a wider view, the cost of delaying business investment.
How often should I review supplier pricing?
At least once a year, and whenever a notice arrives. A quick annual check of your top ten suppliers — prices, terms, service and alternatives — keeps you from drifting into paying more than you need. It also means that when an increase does land, you already know what the market looks like and whether buying ahead, negotiating or switching makes most sense.
Beat the increase without choking cash flow
If the net saving is real and the stock will move, the only question left is how to pay for it without starving wages and tax. A 60-second enquiry is the first step — there’s no credit check to ask. We keep your enquiry to one team rather than broadcasting it, and a real person calls to talk through amount and timing. Please be accurate about the order size, your turnover and when the stock will sell, so we can match the facility properly.
Frequently asked questions
How much stock should I buy before a price rise?
Generally only what you'll sell or use within a few months. The longer stock sits, the more the holding costs eat into the saving, and the higher the risk of it dating or spoiling.
Can I negotiate with a supplier about a price increase?
Often. Ask whether a larger forward order locks the current price, whether the increase can be phased, or whether payment terms can change. Suppliers would usually rather keep a good customer than lose them over a price notice.
Should I pass the increase on to customers?
Usually some or all of it, and ideally with notice. If input costs rise and your prices don't, your margin shrinks every month. Buying ahead buys time to review prices; it doesn't replace doing it.
Is it worth borrowing to buy ahead of a price rise?
It can be, if the saving comfortably exceeds the total dollar cost of the finance and holding costs, and the stock will turn over quickly. Short facilities repaid from the sales are usually the best fit.
