Business loans with irregular or lumpy income

Lumpy income is normal for a lot of good businesses. A builder is paid on progress claims. A software consultancy invoices on milestones. An events company might bank $180k in November and $9k in February. A machinery dealer has months with three sales and months with none. If that’s you, the question isn’t whether you can borrow. It’s how to stop a lender reading the gaps as a warning sign.

How does a lender turn uneven deposits into one number?

Almost every business lender, bank or otherwise, ends up converting your income into a monthly figure it can compare to the repayment. The common method looks like this:

1. Collect six or twelve months of business bank statements, sometimes with BAS or financials for larger loans.
2. Strip out what isn’t income: transfers between your own accounts, loan advances, capital you put in, refunds and reversed payments.
3. Average what’s left across the period.
4. Stress test it against the weakest months, the lowest daily balances and any dishonoured payments.

Step four is where irregular businesses get caught. Your average might be strong, but if the account dropped near zero for six weeks between contracts, the lender wonders how a repayment would have cleared during that stretch. Our page on serviceability explains the test in more detail.

A worked example of the arithmetic

This is illustrative only. A landscape construction business shows these deposits over six months:

Month	Deposits	Notes
May	$142,000	Final claim on a large residential job
June	$38,000
July	$11,000	Wet month, little work
August	$96,000	Two progress claims
September	$21,000
October	$64,000	Includes a $20k transfer from the owner’s savings

Total deposits are $372k. Take out the owner’s $20k transfer and the genuine figure is $352k, or about $58.7k a month. That’s what the lender works from.

Then it looks at July. If the account fell to a few hundred dollars that month and a supplier payment bounced, the lender may cut the amount it offers or ask for security. If the account still held $40k through July because the owner left a buffer from May, the same average looks far safer. The income was identical; the way the cash was held made the difference.

Which other signals count?

Factor	Why it matters with irregular income
Large single deposits	Unexplained lumps may be excluded; explained ones count
Customer concentration	One client providing most of the income is a risk if they leave
Gap length	How long the business goes between payments
Cash buffer	Whether money from good months covers the lean ones
Debtors	Money owed to you is evidence of income still to come
Pipeline	Signed contracts and quotes accepted show the next lumps
Tax position	Irregular businesses often fall behind on BAS after a big quarter

Customer concentration deserves a moment. If 70% of your income came from one head contractor, a lender will think about what happens if that relationship ends. It doesn’t mean a no, but expect questions, and have the contract or a long trading history with that customer ready.

How to present irregular income so it reads well

The goal is to give the lender context it would otherwise have to guess at.

• Label the big deposits. A one-line list of your five largest receipts, with customer and invoice number, removes the guesswork.
• Provide an aged receivables report. It shows what’s owed to you and when it’s due. See our explanation of aged receivables.
• Show the pipeline. Signed contracts, accepted quotes and expected claim dates, kept simple.
• Keep one main operating account. Shuffling money between several accounts makes it hard to tell income from transfers.
• Explain the gaps in a few sentences: weather, project timing, a deliberate break between contracts.
• Use twelve months if the last six were thin, and ask whether the lender will accept it.

If you’re also short on recent financials, our page on business loans without financials covers which lenders will work from statements alone.

Which finance copes with lumpy income?

A bank is worth approaching first if your financials show consistent profit over two or three years, even when the months inside each year are uneven. Banks often look at annual results more than monthly swings, and their pricing is usually the lowest. If a bank declines, or the timeline is too slow, these tend to work best:

Invoice finance. If your income is lumpy because customers pay slowly, borrowing against the invoices themselves fixes the timing directly. Read about invoice finance.

Progress payment finance. Built for contractors paid by stage, advancing against approved claims. See progress payment finance.

A line of credit. Draw in the gaps, clear it when a lump lands. Interest is charged on the balance used, not the limit.

Property-secured lending. Where income is genuinely hard to read, property shifts the decision onto equity. That’s also where low doc and no doc approaches become realistic. Our low doc business loans page sets out the trade-offs.

Fixed daily or weekly repayment loans. Usable for small, short needs, but risky when the next payment from a customer could be six weeks away. Make sure the repayment can clear in your worst month, not your average one.

The tax side of uneven income

The ATO lets you vary PAYG instalments by the instalment due date when this year looks different from last, and under the rate method the instalment follows the income you report. The ATO is clear that varying doesn’t change your total tax for the year, so don’t use it as a way to defer. The government has also announced a dynamic PAYG instalment option from 1 July 2027 that would let businesses base instalments on real-time figures from accounting software, though the ATO notes this isn’t yet law.

Why does this matter for a loan? Because a lumpy business that pays a large instalment based on a big previous year can empty the very reserve a lender hopes to find. A sensible instalment keeps the statements tidier.

Mistakes that make irregular income look worse

• Running business takings through a personal account, so the lender sees only part of the income.
• Applying the week after the account hit its lowest point of the year.
• Leaving large deposits unexplained and hoping they’re counted.
• Taking a daily repayment product sized on your best months.
• Drawing every dollar out of the business after a big payment, leaving no buffer for the gap.

Uneven income, a clear plan

Owners with project-based or deal-based income are usually better at managing money than they get credit for. They just need a lender who reads their figures properly. We take the time to understand where your money comes from and when, then match a lender whose assessment suits that pattern.

Expect the enquiry to take a minute or so. Asking us carries no credit check, so your file stays as it is. We keep your information in-house; it isn’t handed out to a queue of lenders. Someone on our team reviews the shape of your income and calls you. Include your real turnover, the size of your typical gaps and any security you hold, since honest figures are how we land on a suitable lender at the first attempt.
