Funding a cash flow gap: which option fits your business?

“We’re busy, we’re profitable, so why is the account empty?” It’s one of the most common things business owners tell us. A cash flow gap is simply the time between money going out and money coming in — and almost every business has one somewhere.

The trick is working out what kind of gap you have, because each type suits a completely different fix. Let’s diagnose yours first, then match the funding to it.

What kind of cash flow gap do you have?

Think of this as a quick coaching diagnostic. Most gaps fall into one of three types.

1. The recurring gap. It opens and closes on a rhythm. Wages go out every fortnight but customers pay monthly. Stock is bought in March and sold through winter. Progress claims lag behind costs. The gap comes back again and again, but it always closes.

2. The one-off gap. Something specific has created a hole with a known end. A large customer is paying late. A big tax bill landed at the same time as an equipment repair. You’re waiting on a sale, a refund or an insurance payout.

3. The structural gap. Money out is consistently more than money in. Prices haven’t kept up with costs, a big customer has gone, or overheads have crept up. The gap doesn’t close by itself — it grows.

Which funding fits each kind of gap?

Type of gap	Tends to suit	Why
Recurring	Line of credit	Draw when the gap opens, repay when it closes, repeat
One-off with a known end	Short loan	Clear start, clear finish, no lingering debt
One-off and large	Property-secured loan	Larger amounts from $20,000 to $5,000,000
Structural	Fix first, then fund	Funding alone delays the problem

The most common mistake is using a one-off loan to paper over a recurring gap. It works once, then the gap comes back and there’s a repayment on top. The second most common is using funding to cover a structural gap without changing anything underneath.

How do you measure your gap?

A 13-week cash flow forecast is the single most useful tool here. business.gov.au has a template for setting up a cash flow statement. The idea is simple:

1. List your opening bank balance.
2. For each of the next 13 weeks, estimate money in — actual expected receipts, not invoices sent.
3. Estimate money out — wages, super, rent, suppliers, loan repayments, BAS, everything.
4. Calculate the running balance week by week.
5. Find the lowest point. That’s the size of your gap. The weeks either side show how long it lasts.

Our cash runway guide walks through a worked example in detail.

Once you know the size and shape of your gap, a real person can tell you which option fits — the enquiry takes about a minute and there’s no credit check at that first step.

Can you shrink the gap before you borrow?

Often you can, and every dollar you shrink it by is a dollar you don’t need to fund:

• Invoice faster. The same day the work is done, not at month end.
• Shorten your terms. Move new customers to shorter terms, and ask for deposits on larger jobs.
• Chase overdue invoices. business.gov.au has practical steps for when you haven’t been paid.
• Negotiate with suppliers. Longer terms from suppliers narrow the gap from the other side.
• Time big purchases. Schedule non-urgent spending for after your cash peaks, not before.

What do lenders want to see?

• Bank statements showing how your cash moves across several months.
• A clear explanation of the gap — what causes it, how big it is and when it closes.
• Up-to-date lodgements. BAS and tax returns lodged on time.
• Your forecast, if you’ve built one. It shows you understand your business.
• Property details, if the gap is large and you’re offering security.

An illustrative example

Illustrative only. A commercial cleaning company pays its 20 staff weekly. Most of its clients are property managers who pay monthly, often on the 20th of the following month. The owner’s 13-week forecast shows the balance dipping to its lowest point in the second and third week of every month, then recovering.

That’s a textbook recurring gap. His funding plan ranks a line of credit first, sized to the deepest point in his forecast plus a small buffer. He also moves new clients to fortnightly invoicing, which shrinks the gap over time.

When is a cash flow gap a warning sign?

Sometimes the gap is telling you something. Be cautious if:

• The lowest point gets lower every month.
• You’re relying on funding to pay tax or super routinely.
• You’ve taken several short-term advances to cover each other.
• You can’t explain what’s causing the gap.

In those cases, talk to your accountant and look at business.gov.au’s warning signs of financial trouble before borrowing. Our recovering stage guide can help too.

How big a buffer should you build once the gap closes?

Funding closes today’s gap. A buffer stops the next one becoming urgent. Once things settle, many owners set aside a small, fixed share of every good week into a separate account until it covers the depth of their usual dip. It won’t happen overnight, but each month it grows, the less you’ll rely on funding for recurring gaps — and the more choice you’ll have when an opportunity appears.

Got a gap to close? Let’s find the right fit

Cash flow gaps are part of running a business, not a sign of failure. The goal is to match the funding to the gap so it closes cleanly — rather than borrowing the wrong way and making next month harder.

It’s quick to start: about 60 seconds, no credit check, and no sharing your details with a queue of lenders. A real person reads what you’ve told us and calls to talk it through. Accurate answers on the form — especially monthly deposits and the size of the gap — help us match you properly first time.
