Customer disputing your invoice? How to keep cash moving while it's sorted out

When a customer disputes your invoice, split it in two. Ask for the undisputed part to be paid now and put the contested part in writing. Then plan the cash as if the disputed balance could take months, because it can. Invoice financiers often won’t fund a disputed debt, so a line of credit or working capital loan is the usual bridge.

A late payer is annoying. A disputing payer is different. The money isn’t just slow; it’s frozen until someone agrees what’s owed. And because the customer has a reason not to pay, the usual reminders stop working.

Why does a disputed invoice hurt more than a late one?

With a late invoice, everyone agrees on the amount. It’s only a question of when. With a disputed one, the amount itself is in doubt, and that changes three things at once:

• Time stretches. A reminder won’t settle a disagreement about quality, scope or variations. It takes conversation, evidence and sometimes a third party.
• Funding options narrow. Invoice finance is built for clean receivables. A financier typically excludes invoices that are in dispute, so the money you’d normally unlock isn’t available.
• Work in progress gets awkward. If the same customer has more work with you, you’re deciding whether to keep supplying while the argument runs.

That’s why a single disputed invoice can squeeze a business that’s otherwise in good shape, especially when it’s a big job for a big customer.

There’s an emotional cost too. Owners often keep chasing the full amount on principle, long after the cash would have been better spent elsewhere. Deciding early what a sensible outcome looks like, and how long you can afford to wait for it, keeps the dispute in proportion.

How do you get at least some of the money moving?

Start by narrowing the fight.

1. Ask exactly what’s disputed. Is it the whole invoice, one line item, a variation, or a deduction for alleged defects?
2. Request payment of the undisputed amount. Most customers who dispute a $40k invoice don’t dispute all $40k. Ask, in writing, for the uncontested part now.
3. Reissue if it helps. Splitting the invoice into an undisputed invoice and a separate disputed one can make it easier for the customer’s accounts team to pay.
4. Gather your evidence. Contract, quote, variations, delivery dockets, photos, emails and sign-offs. The Queensland Small Business Commissioner recommends keeping evidence such as screenshots and messages, and reviewing your contract’s payment and dispute clauses.
5. Tighten terms on new work. Many businesses keep supplying, but on deposits or upfront payment until things are resolved.

Getting the undisputed portion paid often halves the cash problem overnight.

If the remaining gap is still more than your buffer can carry, send us a short enquiry. There’s no credit check when you first enquire.

How long could the disputed part take?

There’s no single answer, but the usual escalation path looks like this:

Step	What it involves	Typical pace
Reminder and conversation	Clarify the issue, offer evidence	Days to a few weeks
Letter of demand	Formal request, often from a solicitor or collector	A few weeks
Mediation	Independent help to reach agreement	Weeks to a couple of months
Debt collection	An agency pursues it for a fee	Varies
Tribunal or court	Binding decision	Months, sometimes close to a year

The QSBC lists these steps in roughly that order and notes that a template letter of demand is available from business.gov.au. For Queensland, it says a minor debt dispute of up to $25,000 can go to the state tribunal, and that a minor civil dispute takes about 51 weeks on average, depending on location. It also points out that only a court or tribunal can make binding orders in a debt dispute, and that a negotiated settlement for less than the full amount can be the most practical outcome.

For cash flow planning, the lesson is clear: don’t build your budget around the disputed money arriving soon.

Can you borrow while an invoice is in dispute?

Yes, but usually not against that invoice. Here’s how the main options compare:

• Invoice finance. Great for clean receivables, but disputed debts are commonly excluded. You may still be able to finance your other invoices. See invoice finance.
• A line of credit. Assessed on the business as a whole, so the dispute doesn’t block it. Draw what you need and repay when the money finally lands. See business line of credit.
• A working capital or cash flow loan. A fixed amount with a set term, useful when you know roughly how big the hole is. See working capital loans and cash flow loans.
• Property-secured finance. From $20k to $5m, for a large dispute or one that has knocked other parts of the business.

Unsecured and cash-flow options typically run from $5k to $500k, based on turnover and bank statements. Lenders will want to understand the dispute, but a well-documented one with a reasonable plan rarely stops an application on its own.

When you talk to a lender, bring a one-page summary: who the customer is, what they’re disputing and why, the amount already paid, the undisputed amount still outstanding, and where the dispute is up to. Add the contract and the key emails. That turns an awkward conversation into a straightforward one, because the lender can see the dispute is contained and the rest of the business is trading normally. It also helps to size the facility on the disputed amount plus a buffer for slow resolution, rather than on the whole invoice, so you’re not paying for a limit you don’t need once the undisputed part comes in.

What does this look like for a real business?

Illustrative example. An event hire company supplies marquees, flooring and lighting for a large corporate function. The $90k invoice is due in 30 days. The client pays nothing, saying the lighting was installed late and two marquee walls were damaged on arrival.

The owner asks exactly what’s in dispute. The client confirms the problem is limited to the lighting package and the walls, worth $25k combined. The owner reissues two invoices: $65k for undisputed items and $25k for the contested ones. The client pays the $65k within a fortnight.

The remaining $25k goes to mediation two months later and settles at $18k. In the meantime, the company draws on a $50k line of credit to cover crew wages and a big spring order. Our event hire business loan page covers how lenders look at hire businesses, and trades with similar disputes over installs may find the HVAC business loan page useful.

Where can you get help with the dispute itself?

You don’t have to pay a lawyer to take the first steps. The Australian Small Business and Family Enterprise Ombudsman offers case management for eligible small businesses in disputes with another business, generally those with fewer than 100 employees or revenue under $5 million. It can refer some matters for preliminary legal advice, with a $100 co-payment at the first stage. Eligibility depends on the type of dispute, so check before you rely on it.

State small business commissioners also offer information and mediation. A quick call can save weeks.

Dispute dragging on? Don’t let it stall the rest of the business

Most disputes end with some money changing hands. The risk is what happens to your wages, suppliers and next job while you wait. A facility sized to the frozen amount lets you argue your case calmly instead of on the back foot.

It’s a 60-second enquiry with no credit check when you first enquire. We don’t send your details to a pile of lenders, so your phone won’t be swamped. A real person reads what’s happened, including the dispute, and calls you to work out what fits. Please fill in the form accurately, including how much is contested, so we can find the right option first time.
