How agencies manage client payments when clients pay late

Ask an agency owner what keeps them awake and it is rarely the creative work. It is a $48k invoice to a household-name client that has sat unpaid for 75 days while four salaries go out the door.

The structure of an agency makes this worse than in most businesses. The main cost is people, paid on time, every pay cycle. The main asset is a list of receivables, paid when the client’s accounts team gets around to it. Nothing is stored in a warehouse that could be sold.

Why are agencies so exposed to slow payers?

Because your best clients are often your slowest. Large organisations run payment cycles built for their own convenience, and a supplier is a line in a queue.

The Payment Times Reporting Regulator said in February 2026 that large businesses took an average of 64 days to pay 95 per cent of their small business invoices in the first half of 2025, up from 58 days in the previous period. The scheme applies to large businesses with big annual incomes, and the regulator publishes the figures so small suppliers can see who is quick and who is not.

Two things follow. First, 60-plus day terms are the norm in corporate land, not an exception, so price and plan for them. Second, a client’s brand tells you nothing about how fast it pays. Ask for the terms before the work starts, not at the first invoice.

How should you set up payment terms?

Terms are won at the proposal stage. Once the work is delivered, your leverage is gone.

• Retainers billed in advance. Invoice on the first day of the service month, not the last. Even a 14-day term then means you are paid roughly when the work is happening.
• Staged project billing. Deposit on acceptance, a payment at the midpoint, the balance on delivery. Never leave 100 per cent for the end.
• Media and large pass-through costs paid by the client first. Ask for prepayment, or have the client contract directly with the platform.
• A written late-payment clause. A statement that work may be paused after a set number of days overdue is far easier to enforce than a fresh conversation.
• Short terms in the contract, not the invoice. Terms printed only on an invoice are weak; terms agreed in the contract are stronger.

Our guides on getting customers to pay faster and managing slow-paying customers go through the follow-up routine step by step.

What is pass-through risk, and why does it matter?

Pass-through costs are spend you buy on a client’s behalf: media, print, events, freelancers, stock imagery, software seats. They flatter your top line and put your balance sheet at risk.

Say an agency bills $400k a month, of which $300k is media. Its own revenue is $100k. If the media supplier wants payment in 30 days and the client pays in 60, the agency finances $300k for a month. A single client default is no longer a bad debt of fees; it is a loss of the entire media cost.

Practical protections:

1. Separate media invoices and account for them as pass-through, not revenue.
2. Make prepayment the default for large campaign budgets.
3. Where suppliers accept it, agree that payment is due only after client payment, and make sure the client contract mirrors that.
4. Track your net revenue and margin, not gross billings. Lenders will look at both.

How do you know your real cash gap?

Three numbers, all available in your accounting software:

• Debtor days: average days from invoice to payment, by client.
• Fortnightly cost base: payroll, super, contractors, rent and software.
• Concentration: the share of revenue from your top one and top three clients.

Multiply your daily cost base by your debtor days and you have the cash tied up in the system. An agency with $35k of weekly costs and 60 debtor days is funding roughly $300k of its own working capital. Use the cash flow gap calculator or the invoice finance calculator to test it.

What finance fits an agency?

Option	How it helps	Limits
Invoice finance	Advances cash against issued invoices, so a 60-day wait becomes days	Cost rises with the time invoices stay open; clean, undisputed invoices needed
Invoice factoring	Lender can also collect, which suits small teams	Clients may know a third party is involved
Working capital loan	Lump sum sized on turnover, fixed repayments	Repayments continue even if a client delays
Line of credit	Draw and repay as invoices clear	Limits are reviewed; best arranged early

A bank facility is often the cheapest and deserves a proper conversation first. If the bank has said no, or your assets are mostly people and software, invoice-based and cash-flow lending exists because lenders can see value in a debtor ledger of reputable clients. Our page on selling invoices vs borrowing against them explains the difference, and the marketing agencies and recruitment agencies pages cover how lenders view each.

A worked example

This is a made-up scenario. A Brisbane digital agency bills $90k a month in fees, with five staff plus two contractors and monthly costs of $72k. Its three largest clients make up 70 per cent of revenue, all on 60-day terms in practice.

Cash tied up in receivables: about $180k. The owner has $60k in the bank and a $120k shortfall in a normal month.

Moves, in order:

1. Convert two clients to monthly retainers billed in advance. That alone pulls roughly $30k forward.
2. Require a 50 per cent deposit on project work above $20k.
3. Arrange a $100k invoice finance facility against the three large clients. At an average of three weeks outstanding after the advance, the total fees in dollars are modest compared with the cost of missing a payroll or turning down a contract.

The facility stays in the background, the process changes reduce its use, and the next large win is something to celebrate and not to fear.

What should you do when an invoice is already late?

Lateness is easier to deal with when you have a routine, not a mood. A simple sequence:

1. Day 1 after the due date: a friendly reminder to the named accounts contact, with the invoice and purchase order number attached.
2. Day 7: a call, not another email. Ask what is holding the invoice and when it will be paid, and write down the answer.
3. Day 14: escalate to the person who commissioned the work, pointing to the contract term.
4. Day 21 or later: pause new work if your contract allows it, and say so plainly.

Keep the tone professional. Most late payment is an internal queue, not a dispute, and a client who feels respected pays sooner. If a client is genuinely refusing to pay, or is slipping into trouble, the Australian Small Business and Family Enterprise Ombudsman has information for small businesses dealing with payment problems, and it is worth knowing your options before the debt ages further.

It also helps to review client terms once a year. If your top three clients have all drifted from 30 to 60 days, that is a pricing conversation, and it is better to have it at renewal than at the next cash crunch.

Where does an enquiry fit?

If you are already running a thin cash buffer and your biggest client has just moved to longer terms, arranging finance now is far easier than waiting for an invoice to go 90 days. We hear this from agency owners regularly, and the right answer is often a mix of better terms plus a modest facility.

Our enquiry form takes about a minute, and it leaves your credit file alone. Nothing is forwarded to a long list of lenders. A real person reads your details and calls you. Include your biggest clients’ payment history and monthly costs accurately so the first option we discuss is the one that fits.
