Quick answer
An online store can be selling well and still run out of cash, because money goes out for stock, ads and freight long before payouts come back. Early warning signs include growing stock on hand, rising ad costs per sale, longer payout delays, more refunds, supplier deposits creeping up and relying on platform cash advances. Spotting them early lets you fix pricing, stock and timing — and, if needed, arrange finance before it's urgent.
Key points
- Sales growth often makes cash tighter before it makes it looser.
- Stock, ad spend and payout timing are the three big cash traps for online stores.
- Watch trends month to month, not single bad days.
- Fix pricing and stock first; use finance to bridge timing, not losses.
- Arrange finance before you need it — not the week a supplier wants paying.
Running an online store has a strange cash-flow quirk: the better things go, the tighter the bank account can get. More orders mean more stock to buy, more ads to run and more freight to pay — all before the platform pays you for the sales. Plenty of growing stores hit a wall not because customers stopped buying, but because the cash couldn’t keep up.
The good news is that a cash crunch almost always sends signals first. Here are nine to watch, what each one means, and what to do about it — whether or not finance ends up being part of the answer.
Why is cash flow different for online stores?
A bricks-and-mortar shop sells, takes the card payment and sees the money within a day or two. An online store usually has more moving parts between the sale and the cash: payment gateways that settle in batches, marketplaces that pay out on their own schedule and may hold reserves, buy-now-pay-later providers, returns that come out after the sale, and ad platforms that bill in advance or as you spend.
business.gov.au describes the main ways to sell online — your own site, marketplaces and social storefronts. Many stores use all three, and each has its own payout timing. Add overseas suppliers who want deposits before production, and the gap between spending and earning can stretch to months.
Warning sign 1: Stock on hand is growing faster than sales
If the value of stock in your warehouse is rising month after month, but sales aren’t rising at the same pace, cash is quietly turning into boxes. Work out your weeks of stock: stock on hand divided by average weekly sales of that stock. If that number keeps climbing, you’re over-ordering or some products have stalled.
What to do: identify slow movers and run a clearance; reduce reorder quantities; consider ordering bestsellers more often in smaller batches. business.gov.au’s cash-flow tips include buying stock closer to when customers order rather than holding excess.
Warning sign 2: Your cost per sale from ads keeps rising
Ad costs naturally climb in competitive periods. But if your cost to acquire each order is trending up over several months while order values stay flat, every sale is earning less cash than it used to.
What to do: review which campaigns and channels still pay back, cut the ones that don’t, and work on conversion — product pages, photos, checkout. Don’t borrow to scale ads until payback is stable; see funding ad spend and growth.
Warning sign 3: Payouts are taking longer to arrive
A change in payout timing, a new reserve on a marketplace account or a switch to a slower payment method can stretch the gap between sale and cash by days or weeks — and you may not notice until a bill is due.
What to do: check each platform’s payout settings and any holds; ask whether a reserve can be reduced once your account is established; route all payouts to one business account so you can see them clearly. Our page on finance for marketplace sellers covers payout quirks in detail.
Warning sign 4: Refunds and returns are creeping up
Every refund takes cash back out after you’ve counted the sale. A rising return rate also often comes with freight costs both ways and stock that can’t be resold at full price.
What to do: look for patterns by product, size or supplier; improve product descriptions and sizing guides; review quality with the supplier. A small improvement in returns often frees more cash than a price rise.
Warning sign 5: Supplier deposits are getting bigger or earlier
If suppliers are asking for larger deposits, or for full payment earlier, your cash leaves sooner — and the gap to payout widens.
What to do: negotiate. business.gov.au suggests negotiating improved terms with suppliers as a cash-flow lever. A track record of reliable payment strengthens your position. Splitting orders across shipments can also spread payments.
Warning sign 6: You’re juggling which bills to pay first
If you’ve started deciding which supplier, freight company or ad platform to pay this week and which to push to next week, the business is already running on a cash shortfall, even if the profit and loss looks fine.
What to do: build a simple 13-week cash forecast — money expected in, money going out, week by week. It turns juggling into planning, and shows exactly when and how big the gap will be.
Warning sign 7: You’re stacking platform cash advances
Many platforms offer quick advances inside your seller account, repaid as a share of future payouts. One can be useful. Two or three at once can take a large slice of every payout, leaving too little for the next stock order — which leads to another advance.
What to do: add up the total cost and the share of payouts each one takes. If you’re stacked, consolidating into one structured facility may help; see refinancing business loans online.
Warning sign 8: GST and tax are paid from whatever’s left
If BAS is paid from whatever is in the account on the due date, rather than from money set aside, a slow month before a due date becomes a crisis. Online sellers are also on the ATO’s radar: the ATO runs an online selling data-matching program focused on registration, reporting and payment obligations, and GST registration is required within 21 days once GST turnover reaches $75,000.
What to do: open a tax account and transfer the GST component of every payout into it. Our guide to tax-time cash-flow gaps explains how to map the dates.
Warning sign 9: You’re out of stock on bestsellers during peaks
Running out of your best products during the busiest weeks is the most expensive cash-flow problem of all: you’ve paid for the ads and the traffic, but can’t take the orders.
What to do: plan peak-season stock months ahead, working back from last year’s sales and supplier lead times. If cash is the constraint, arrange funding early — see funding stock for peak season.

When does finance help — and when doesn’t it?
Finance helps when the store is fundamentally profitable but the timing of cash is the problem: stock paid months before peak, ads paid before payouts, suppliers wanting deposits. A line of credit is often the natural fit, drawn for each order and repaid as sales arrive.
Finance doesn’t help when the store is losing money on each sale, when returns are out of control, or when stock is piling up unsold. In those cases, borrowing just delays the reckoning. Fix pricing, margin and stock first.
Illustrative example: a fast-growing activewear brand
Illustrative only. A small activewear brand doubled its online sales in a year. The founders were thrilled — until they noticed they were paying suppliers late and delaying their own pay. Their check showed weeks of stock rising on two slow colourways, ad cost per order up, and two platform advances taking a share of every payout.
They ran a clearance on the slow lines, cut two underperforming campaigns and stopped taking new advances. Then they enquired online about a line of credit to fund the next season’s bestsellers ahead of time. With bank data showing a clear seasonal pattern and improving margins, a modest facility was arranged, and the stacked advances were paid out.
Spot it early, fix it calmly
A cash crunch is far easier to fix in its early weeks than in its final days. Watch these nine signals monthly, and act on the trend rather than the panic.

Frequently asked questions
How can my store be profitable but out of cash?
Profit is measured when you sell; cash moves when you pay suppliers and when platforms pay you. If stock and ads are paid weeks before payouts arrive, a profitable store can still run short.
Which number should I watch most closely?
Weeks of stock on hand, compared with how fast it's selling. Cash tied up in slow stock is the most common hidden drain.
Are platform cash advances a bad idea?
Not always, but they can be expensive and take a share of every payout. Several at once can starve the business of cash. Compare the full cost first.
When should an online store consider a line of credit?
When the business is genuinely profitable but cash timing — stock before sales, ads before payouts — keeps pinching. Arrange it before a crunch, not during.
Do I need GST registration?
Once your GST turnover reaches $75,000, the ATO requires you to register within 21 days.
