Black Friday sales Australia-wide are now one of the busiest times of the year for product businesses, and the stock problems that hurt the most usually start a few weeks before the sale begins.
It often goes like this. Someone picks 20 products for the promotion, and nobody checks how many of each are actually in the warehouse. The sale goes live and your website says you have 40 units of your best seller. You really have 26, because a wholesale order took the rest and your systems haven’t caught up. Within an hour you’ve sold 40, and you’re emailing 14 customers to say sorry. Some of them will take a refund and buy from someone else.
This year, more is riding on getting it right. Roy Morgan expects Australians to spend $7.2 billion over the Black Friday and Cyber Monday weekend, up 5.5% on last year’s forecast. Black Friday falls on 27 November 2026, so you have about three weeks to make sure your website, your warehouse and your accounts all show the same numbers.
This guide walks through simple, practical Black Friday inventory planning for wholesalers, distributors, retailers and manufacturers, with a checklist at the end you can start on this week.
Black Friday Sales Australia 2026: What the Numbers Show
The latest figures for Black Friday sales Australia-wide show a bigger event than last year, with shoppers buying earlier and placing smaller orders. Here is what matters most if you’re planning stock.
- Bigger Weekend: The Australian Retail Council’s Peak Season Hub reports a Roy Morgan forecast of $7.2 billion in Black Friday and Cyber Monday spending, up 5.5% on last year’s $6.8 billion forecast.
- A Record Fortnight Last Year: CommBank iQ data shows Australians spent a record $23.8 billion across the Black Friday fortnight in 2025, 19.5% more than in a normal two weeks.
- Smaller Orders: The same data shows online spending rose 17% to $25 billion in the September quarter of 2026, but the average online order fell 6.8% to $90.
- Fast Delivery Matters: Australia Post’s October 2026 eCommerce update found one in two shoppers expect faster delivery during sales, and half would switch to another store to get it.
- Spending Across Categories: The ABS reported that household spending rose 1.0% in November 2025, with Black Friday lifting clothing, footwear, furniture and electronics.
Smaller orders are the part to watch. The same revenue now means more orders to pick, pack and ship, and every extra movement is another chance for your stock records to go wrong.
These are the key dates for this year:
| Date | Event | What It Means for Your Stock |
|---|---|---|
| Early to mid November | Early sales | Promoted products start selling before the big weekend. |
| Friday 27 November 2026 | Black Friday | Your busiest day for orders. |
| 28 to 29 November | The weekend | Hard to move stock between locations. |
| Monday 30 November 2026 | Cyber Monday | The last big day of the sale. |
| 1 to 7 December | The week after | Returns, late orders and checking your numbers. |
Where Businesses Lose Sales Without Noticing
Most lost sales during Black Friday come from small problems that seem minor on the day but add up over the weekend. These are the most common:
- Best Sellers Running Out: Your most promoted products sell out on Friday morning, while your ads keep sending people to a page that says “out of stock”.
- Selling the Same Item Twice: Your website and a marketplace both sell the last few units before stock levels update.
- Stock That Can’t Be Sold: Damaged items, or deliveries that were never checked in properly, still show as available.
- Stock in the Wrong Warehouse: You have plenty overall, but the warehouse that ships your online orders has run out.
- Wholesale Orders Not Set Aside: Stock promised to trade customers still shows as available to online shoppers.
- Slow Shipping: Orders that sit for days get cancelled, and since half of shoppers would switch stores for faster delivery, you may lose their next order too.
Each of these can be fixed in the next three weeks.
Black Friday Inventory Planning Starts With Your Promotion List
Most Black Friday promotions are picked by marketing, based on what will get attention. Black Friday inventory planning works better when you check stock first, because discounting a product you can’t deliver earns you nothing and annoys the customer.
Before a product goes into an email or ad, ask three simple questions. How many do we have right now? How many more will arrive before 27 November? How quickly did it sell last Black Friday? Then use the answers to decide how to promote it.
| Your Stock Situation | What to Do |
|---|---|
| Plenty in stock, more on the way | Make it a headline deal |
| Good stock, nothing more arriving | Promote it, but show a quantity limit or run a shorter offer |
| Low stock on a top seller | Leave it out of big ads and sell it at full price |
| Slow-moving or excess stock | Bundle it or discount it more to free up cash |
| New products with no sales history | Promote a small amount and have a reorder ready |
If you’re still working out how much to order, the free SKU planning tool shows how many units to buy and the latest date to order each product. For a step-by-step forecasting method, read the guide on holiday inventory forecasting.
There’s a legal side to this too. Under the ACCC’s rules on bait advertising, you can’t advertise a product at a sale price if you can’t supply a reasonable amount of it for a reasonable time.
The ACCC is paying close attention. In April 2026, it said around half of the 50 retailers it checked in its 2025 Black Friday review made concerning advertising claims, such as countdown timers and “sitewide” deals with hard-to-see exclusions. The simplest protection is to be honest and clear about quantity limits and end dates.
It’s also worth checking your real profit on each discounted product. Many businesses record only the supplier price as their cost, and leave out freight, duty and insurance. The example below uses made-up numbers.
| Example (ex GST) | Supplier Price Only | Real Cost Including Freight and Duty |
|---|---|---|
| Cost per unit | $50.00 | $62.00 |
| Profit at normal price of $120 | $70.00 (58.3%) | $58.00 (48.3%) |
| Profit at 25% off ($90) | $40.00 (44.4%) | $28.00 (31.1%) |
In this example, leaving out freight and duty makes each sale look $12 more profitable than it really is, before card fees or marketplace fees. Check this before your sale prices go live.
Keeping Stock Accurate Across Every Sales Channel
If you sell through a website, a marketplace, a shop and wholesale accounts, they all draw from the same pool of stock. One of the best ways to manage inventory during Black Friday weekend is to decide before the sale how much each channel is allowed to sell.
If you use Cin7 Core, these settings help most:
- Show Only Stock That’s Free to Sell: Cin7’s Shopify integration guide confirms Cin7 Core sends Shopify the available quantity, which leaves out stock already set aside for other orders.
- Keep a Few Units Back: Cin7 Core lets you set “buffer inventory” for Shopify. Holding back a few units of your best sellers protects you if stock levels take a moment to update during a rush.
- Set Aside Wholesale Orders Early: Lock in confirmed trade orders before the sale, so online shoppers can’t buy that stock.
- Check Bundles and Kits: If Cin7 Core builds bundles automatically from parts, your available stock may include bundles that haven’t been made yet. Make sure your team can put them together fast enough.
- Link Each Channel to the Right Warehouse: Make sure each sales channel pulls from the warehouse that actually ships its orders.
If your Cin7 Core setup has grown over the years and nobody has reviewed it lately, ask experienced Cin7 Core specialists to check it before the weekend. A small setting issue is easy to ignore in March and very costly in the middle of Black Friday.
Check Your Stock and Your Books Before the Sale
All of the above only works if your starting numbers are right. If Cin7 Core, Xero and your warehouse show different numbers before the sale, the difference usually gets bigger during it.
Work through these steps over the next two weeks:
- Count Your Promoted Products: Do a quick physical count of everything on sale and your fastest sellers, then fix any differences in your system.
- Clear the Backlog: Check in any deliveries that have arrived, finish transfers between locations and write off damaged stock.
- Match Your Systems: Make sure the stock value in Cin7 Core matches the inventory figure in Xero.
- Stop Making Changes: Avoid editing product codes, bundles or prices in the last few days before the sale.
- Place Test Orders: Put through a test order on each channel and check it flows all the way to shipping and into your accounts.
This is where your warehouse and your finance team need to work together. Good inventory accounting support makes these checks routine, so you can trust your Black Friday results when you look back in December.
How to Handle the Sale Weekend Itself
Good planning gets you to Friday morning. After that, it comes down to how quickly someone notices a problem and fixes it.
Agree on these simple rules before the sale starts:
- Put One Person in Charge: Give one person the authority to pause ads or change a deal without waiting for approval.
- Watch Your Best Sellers Every Hour: Decide in advance what you’ll do when a top product is about to run out.
- Have Backup Products Ready: Pick similar products with more stock, so you can switch your ads quickly.
- Check Orders Every Morning: Compare the orders on each channel with Cin7 Core to catch anything that didn’t sync.
- Update Sold-Out Products Fast: Change the listing and stop the ads as soon as something sells out.
When these rules are agreed in advance, the weekend becomes a set of quick, calm decisions.

Final Thoughts
Black Friday in Australia now runs across most of November, and it puts pressure on every weak spot in your stock records at once. The businesses that handle Black Friday sales Australia-wide well tend to do the same few things. They only promote stock they can actually ship, decide how much each channel can sell, make sure their counts and accounts match before the sale, and agree on clear rules for the weekend.
It all comes back to one thing.
