Most cash problems in a small business start as management problems. Fix debtors, stock and supplier terms first, then size any finance to the gap that is left.
Quick Answer
Working capital management is how a small business controls the cash tied up in unpaid customer invoices, stock on the shelf and bills still to pay, so the business funds its own cycle before it borrows. Work those three levers first, check the result against a cash flow forecast, then size any working capital loan to the gap that is left.
Also called: working capital cycle management, net working capital. Net working capital is the balance on a given day; working capital management is the practice of moving that balance in your favour.
What does working capital management mean for a small business?
For a small business, working capital management means deciding, on purpose, how long cash sits in customer debts, in stock and in the gap before suppliers are paid. Every business has that gap. The difference is whether the owner runs it or it runs the owner.
There are three levers: what customers owe you, what you hold in stock, and what you owe suppliers. Move any one of them and the cashflow in the bank account changes, often within weeks, without a cent of new debt. That is why the rule in this post is three levers before one loan.
In deals I've seen, an owner asking for a bigger facility is often describing a lever problem: a customer who drifted from paying in a month to paying in two, or a reorder habit that grew faster than sales. Finance can cover that, but it costs interest every month the habit continues. Fixing the lever is free. If you run a business across any of the industries on the Business Owners Hub, the same three levers apply; only the size of each one changes.
What is the working capital cycle, in plain terms?
The working capital cycle is the loop from the day cash goes out to pay for stock, materials or labour to the day it comes back in from a paying customer. The longer the loop, the more cash the business has to carry to keep trading. These are the terms you will hear from an accountant or a lender:
- Debtor days. How long, on average, customers take to pay you after you invoice.
- Stock days. How long stock or materials sit before they are sold or used on a job.
- Creditor days. How long you take to pay your own suppliers.
- Cash conversion cycle. Debtor days plus stock days, less creditor days. It is the number of days your own cash is funding the business.
- Net working capital. Current assets less current liabilities on a given date. A snapshot, not a cycle.
- Current ratio. Current assets divided by current liabilities. A quick read of whether short-term bills are covered.
You do not need to calculate these to the decimal to manage them. The worked formula and a step by step cash conversion cycle example sit in our working capital loans guide. What matters here is the direction: every day you take off debtors or stock, or add to creditors, is a day of cash you no longer have to find.
How do you reduce debtor days and late payments?
You reduce debtor days by invoicing faster, setting tighter terms before the work starts and following up on a fixed rhythm rather than when cash runs short. Debtor days are borrowed time: every day a customer holds your money, you are lending to them for free, and often funding that loan from your own overdraft.
- Invoice the day the work is done. A week's delay in sending the invoice is a week added to every payment.
- Agree terms in writing up front. Put the due date, not just "net terms", on the quote and the invoice.
- Check new customers before you extend credit. A company credit check is cheaper than a bad debt.
- Ask for deposits or progress payments on large jobs. It shortens the loop before it starts.
- Follow up on a calendar. A reminder before the due date, a call on the day, a firm note a week later.
Big customers deserve a separate look. Under the Payment Times Reporting Scheme, large businesses report how quickly they pay their small business suppliers, and those reports sit on a public register. Before you accept a big customer's terms, you can check how they actually pay. If a large customer pays you late, the Australian Small Business and Family Enterprise Ombudsman can help with the dispute. The official overview is on the Payment Times Reporting Regulator's small business page.
Where customers are sound but slow, and the terms cannot be shortened, invoice finance turns approved invoices into cash before the customer pays. That is a finance answer to a debtor lever, and it works best after the collection habits above are in place.
How do you free up cash tied up in stock?
You free up cash in stock by holding less of what sells slowly, ordering closer to when you need it and clearing dead lines rather than carrying them. Stock is cash on a shelf: it cannot pay wages or the tax bill until someone buys it.
- Rank lines by how fast they move. The slow tail usually holds more cash than owners expect.
- Set reorder points from sales, not habit. Reorder when stock falls to a level that covers the supplier's lead time, not when the shelf looks thin.
- Question minimum order quantities. A bulk price saving can be wiped out by months of cash sitting in boxes.
- Clear dead stock. Selling at cost or below converts a frozen asset into working cash.
Importers face the longest stock loop, because cash leaves when the order is placed and the goods may not land for weeks. If that is your business, the funding side of that loop is covered in our trade finance guide for importers. For everyone else, build stock purchases into a rolling cash flow forecast so the big orders are planned around the months when cash is strongest.
How do supplier terms and early payment discounts change your cash?
Supplier terms change your cash by deciding how long you can hold money before it leaves, and an early payment discount is a trade: you give up that time in exchange for a lower price. Terms are free credit until they are not: stretch them past the due date and the supplier can put you on cash on delivery, which pulls the whole loop forward at once.
The practical moves are simple. Ask for longer terms when you are a reliable payer, because a good payment record is a negotiating asset. Line up supplier due dates with the dates your customers usually pay. And treat any early payment discount as a return on cash: if the discount is worth more than the cost of borrowing that money for the same period, it is usually worth taking, provided you are not borrowing at a higher cost to pay early.
The timing of paying suppliers before customers pay you is worked through step by step in our guide on how to pay suppliers before customers pay. If a large customer offers to pay you early through a program, our note on supply chain finance for small suppliers explains the trade. And if a supplier has already cut your credit, the supplier cut credit guide covers what to do next.
What does good working capital look like for your industry?
Good working capital looks different by industry, so the useful comparison is your business against similar businesses and against your own last few years, not against a single textbook number. A cafe turns stock in days and is paid at the till. A manufacturer can carry raw materials for months and wait on long trade terms. A builder carries labour and materials until a progress claim is paid. All three can be healthy with very different cycles.
Three checks tell you more than any single ratio:
- Direction. Are debtor days and stock days getting longer as the business grows? A cycle that stretches with growth is the usual reason a profitable business runs short of cash.
- Peers. The ATO publishes small business benchmarks by industry, which show typical cost and turnover ratios for businesses like yours. They are a sense check, not a target.
- Cover. Do current assets comfortably cover the bills due in the next few months? A current ratio that sits close to even, or below it, is a sign the cycle is carrying too much.
The pattern I see most is a business that is profitable on paper but short in the bank, because growth has lengthened the loop faster than the owner noticed. That is a management signal first.
When is better management not enough?
Better management is not enough when the levers are already tight and the business still has a timing gap it cannot close on its own, usually because of growth, seasonality or customers whose terms you cannot change. The gap that is left is the finance question, and it is a smaller, cheaper question than the one you started with.
| Lever | What you change | How soon cash moves | What to watch |
|---|---|---|---|
| Debtors | Invoice timing, written terms, deposits, a fixed follow-up rhythm, credit checks on new customers | Typically within one or two billing cycles, once invoices go out faster | Pushing too hard on a key customer; a few large debtors holding most of the balance |
| Stock | Reorder points, order sizes, clearing slow and dead lines | Gradual, as sales run down existing stock; faster if dead stock is cleared | Running out of fast sellers; bulk discounts that lock up cash for months |
| Suppliers | Negotiated terms, aligned due dates, selective use of early payment discounts | From the next order once new terms are agreed | Paying late and losing credit; taking a discount with borrowed money that costs more |
The table is a practitioner view, not a lender rule; how fast each lever moves varies by business and by customer. Once the levers are working, the remaining gap points to the right facility:
Management will likely close it
- Invoices go out late or terms are unclear
- Slow stock lines hold a large share of cash
- Supplier terms have never been negotiated
- The cash squeeze grew with old habits, not new sales
The gap likely needs finance
- Collections are tight but a large customer pays on long terms
- Sales are growing faster than cash can follow
- A seasonal peak needs stock or wages before revenue
- A large contract needs costs paid before the first payment
A short wage gap points to payroll gap finance. A gap that comes and goes through the year suits a business line of credit. A gap tied to a large debtor book suits debtor finance. Which of those fits, and how it is sized, is a conversation to have once you know the shape of the gap.
How do lenders read your working capital position?
Lenders read your working capital position by looking at how cash moves through your accounts over time, not just at the balance on the day you apply. Lenders read the cycle, not just the balance: a healthy balance that dips hard every month tells a different story from a modest balance that holds steady.
The first document a lender opens is usually the bank statements: when money arrives, when it leaves, how often the account runs close to empty, and whether other lenders are already debiting it. An aged debtors list with a few long overdue accounts, or ATO arrears building alongside a growing debtor book, both point to a cycle under strain. Many non-bank lenders now run a cash flow assessment straight from bank data, which is why cash flow lending often weighs bank data above a credit score.
The practical point: the management work in this post shows up in the statements. Faster collections, steadier stock spending and supplier payments on time make a business easier to lend to, and usually for a smaller, cheaper amount than it would have needed before.
Working capital management is the work of shortening the time your own cash funds the business. Debtors, stock and supplier terms are the three levers, and each can release cash without new debt. Measure the direction of your cycle against your own history and your industry, then treat whatever gap remains as the finance question. Lenders read the same cycle in your bank statements, so the management work also makes the finance easier to get.
Key takeaway: pull the three levers first, then size any facility to the gap that is left, not to the problem you started with.Frequently Asked Questions
Working capital management is the practice of controlling how long a business's cash is tied up in customer debts, stock and the time before suppliers are paid. The aim is for the business to fund its own operating cycle as far as possible before it borrows. It also shapes how a lender reads the business, because cash flow lending looks at that cycle in your bank data.
The working capital requirement of a business is the amount of cash it needs to carry its operating cycle, from paying for stock, materials or wages to collecting from customers. It grows as sales grow or as customers take longer to pay, and shrinks when the cycle is shortened. Any shortfall is what a facility is sized to, and our guide to working capital loan costs covers what that finance typically costs.
The Payment Times Reporting Scheme is a Commonwealth scheme under which large businesses report how quickly they pay their small business suppliers, with the reports published on a public register. Small suppliers can use it to see how a large customer actually pays before agreeing terms. Pair it with a company credit check on any new customer you plan to extend credit to.
A good current ratio for a small business depends on its industry, but in general current assets should comfortably cover the liabilities due over the coming months. A ratio close to even, or below it, suggests the cycle is carrying too much, while a very high ratio can mean cash is sitting idle in stock or debtors. Lenders weigh it alongside a cash flow assessment rather than on its own.
Taking an early payment discount from a supplier is usually worth it when the discount is worth more than the cost of holding that cash for the same period. It is rarely worth it if paying early means borrowing at a higher cost or leaving the business short before customers pay. Our guide on how to pay suppliers before customers pay covers the timing side.
