What To Do When A Customer Account Is In Arrears

When you’re running a small business, cash flow is everything. So when a customer’s account falls into arrears and starts creeping from “a few days late” to “this is becoming a pattern”, it can quickly turn into a serious operational problem.

The tricky part is balancing the commercial reality (you need to be paid) with the relationship side (you may want to keep the customer) and the legal side (you need to chase the debt in a way that’s fair, compliant, and doesn’t accidentally create a bigger dispute).

This guide walks you through practical steps you can take when an account is in arrears, what to document as you go, and how to set up your contracts and processes so this happens less often in the future.

What Does “Account In Arrears” Mean (And Why It Matters)?

An account in arrears generally means a customer has an overdue balance - they’ve missed the agreed payment due date under your invoice, subscription, payment plan, or credit arrangement.

In plain terms: the customer owes you money, and it’s late.

It matters because the longer a debt remains unpaid, the harder it often becomes to recover. It can also create knock-on effects like:

• difficulty paying your own suppliers and staff on time
• time spent following up invoices instead of running your business
• increased risk of disputes (“we never agreed to that price” or “the work wasn’t done properly”)
• pressure to keep supplying goods/services even though you’re not being paid

Most importantly, the way you respond early can determine whether you get paid quickly, end up negotiating a payment plan, or have to escalate to formal recovery steps.

First Steps: Confirm The Debt And Get Your Paperwork In Order

Before you send firm emails or threaten any action, it’s worth pausing to confirm you’re on solid ground. A surprising number of arrears situations turn into disputes because the basics weren’t properly documented.

Check The Key Facts

Go back to your records and confirm:

• What was agreed? (scope, pricing, deliverables, timing)
• What did you deliver? (and when)
• What was invoiced? (and when)
• What are the payment terms? (e.g. 7 days, 14 days, end of month)
• Has the customer raised a complaint? (even informally)

If you have a signed contract, terms and conditions, or accepted quote, pull that out now. If your arrangement was less formal, gather emails, messages, purchase orders, and proof of delivery.

If you’re regularly supplying goods or services to customers, having clear Terms of Trade can make this step much easier because the payment expectations (and what happens if the customer is late) are already set out.

Make Sure Your Invoice Is Clear And Correct

It sounds basic, but if an invoice is missing key details, it can slow payment and give the customer excuses to delay. Check that your invoice includes:

• your business name and ABN
• invoice number and date
• description of goods/services provided
• amount payable (including GST if applicable)
• payment due date
• payment method details

If there’s any genuine error, fix it quickly and re-issue the invoice. A clean paper trail helps you resolve the matter faster - whether amicably or formally.

Pause Further Supply (If You’re Allowed To)

If the customer’s account is in arrears and the balance is growing, you might be able to suspend further services or stop supplying further goods until payment is made - but only if your contract, terms, or credit arrangement clearly gives you that right.

This is often a key lever in getting accounts paid, but you need to do it carefully. If you stop delivering without a contractual right (or without following any required notice process), you can create an argument that you breached the agreement first.

This is one reason why a tailored Customer Contract (or properly drafted terms) can be so useful - it gives you clear options if payment isn’t made.

How To Follow Up An Account In Arrears (Without Making Things Worse)

Once you’ve confirmed the debt is legitimate and outstanding, the next step is a structured follow-up process. Consistency matters here - both for professionalism and for evidence if you need to escalate later.

Step 1: Friendly Reminder (Short, Clear, Specific)

Start with a polite reminder. Many late payments happen due to simple admin issues, especially in B2B relationships.

Your reminder should include:

• invoice number and amount
• original due date
• a copy of the invoice attached
• a clear request for payment by a specific date (e.g. within 3 business days)

Keep it calm and factual. Avoid accusations. Your aim is to prompt action, not trigger defensiveness.

Step 2: Second Notice (Firm, With Consequences)

If you don’t get a response, send a firmer follow-up. At this stage, you can start referencing the consequences that apply under your terms, such as:

• late fees or interest (only if your contract/terms allow it, and only as set out in those terms)
• suspension of service or supply (where your contract allows)
• credit hold or cancellation of future orders (where your terms permit)

Be careful about adding “late fees” after the fact if you didn’t originally have them in your contract. Surprise charges are a common cause of disputes, and they can undermine your negotiating position.

Step 3: Phone Call (Document What Was Said)

A phone call can be very effective, particularly if emails are being ignored. The goal is to understand what’s actually going on and secure a commitment date for payment.

After the call, send a short email confirming what was discussed (for example, “Thanks for your time today - confirming you’ll pay $X by Friday”). This creates a written record.

If you’re considering recording calls for your own records, check the applicable Australian laws for the state or territory you (and the other person) are in, as the rules vary and can depend on the circumstances (including whether consent is required).

Step 4: Payment Plan (Get It In Writing)

If the customer can’t pay in full, a payment plan might be the best commercial outcome - as long as it’s realistic and properly documented.

At a minimum, confirm in writing:

• the total amount owing
• the instalment amounts and due dates
• how payments will be made
• what happens if they miss a payment (for example, the full balance becomes due)

If you’re going to keep providing services while the customer is in arrears, be extra careful. You may want to require partial upfront payments for future work so the arrears doesn’t keep growing.

When You Can Escalate: Formal Demand Letters And Debt Recovery Options

If friendly follow-ups haven’t worked, it may be time to escalate. The key is to do it in a structured way that signals you’re serious and prepared - without jumping straight to expensive litigation.

Send A Formal Letter Of Demand

A letter of demand is usually the next step for an overdue account that won’t be resolved informally. It is a written notice that:

• sets out the amount owed and why it’s owed
• specifies a deadline to pay (often 7–14 days)
• states what you’ll do if payment isn’t made (for example, commence legal action)

Even when you have a good relationship with the customer, a formal demand can be a useful circuit-breaker. It moves the matter from “accounts payable backlog” to “this needs attention”.

It’s also helpful because it forces you to clarify the legal basis of the debt (contract, invoice terms, proof of delivery), which is exactly what you’ll need if the matter escalates further.

Consider The Best Recovery Path For Your Situation

The right next step depends on the amount owed, the evidence you have, and whether the customer is disputing the debt.

Common options include:

• Negotiation: if the customer is responsive and just needs time or clarity.
• Debt collection: can be useful where you want to outsource follow-up (but you still need good records and a lawful approach).
• Small claims / tribunal / court processes: if the customer won’t engage and you have strong evidence. The process differs by state/territory and by the amount claimed.
• Insolvency considerations: if the customer appears unable to pay anyone, not just you (this can change your strategy significantly).

Before you spend money chasing a debt, it’s worth assessing the commercial reality: will the customer actually be able to pay if you win? A “paper win” isn’t always a real recovery.

Stay Compliant When Chasing Payment

When you’re frustrated, it can be tempting to send aggressive messages or “name and shame”. That approach can backfire quickly.

As a general rule, keep your communications:

• accurate (don’t exaggerate what’s owed or threaten actions you can’t take)
• professional (assume the messages may be read by a lawyer or a court later)
• consistent (stick to one version of events and one amount owing)

If you’re providing goods or services to consumers, your approach also needs to align with the Australian Consumer Law (ACL). For example, a late payment doesn’t automatically remove a customer’s rights to raise a complaint or seek a remedy under consumer guarantees, so it’s important to separate “the debt” from “a complaint” and handle both properly.

Preventing Accounts Falling Into Arrears: Contracts, Terms, And Better Systems

Most small businesses don’t want to become “debt recovery experts”. The better long-term play is setting up your processes so fewer customers fall behind, and when they do, you have clear rights and clear next steps.

Use Clear Payment Terms From Day One

If your payment terms are vague (or buried in a quote that no one reads), you’ll spend more time debating what was agreed than actually getting paid.

Your terms should cover:

• when invoices are due (and what happens if the due date falls on a weekend/public holiday)
• whether deposits are required
• what happens if payment is late (interest, recovery costs, suspension rights - if and to the extent your terms allow)
• any credit limits (if you offer ongoing credit)

This is often easiest to do through well-drafted Terms and Conditions that apply to all customers and are consistently issued before supply begins.

Consider Deposits, Milestones, Or Upfront Payments

If you’re seeing repeat arrears issues, it may be a sign your payment structure needs to change.

Depending on your industry, common approaches include:

• Deposit before starting work (reduces your exposure if the customer disappears)
• progress payments tied to milestones (helps keep cash flow steady)
• full upfront payment for smaller jobs or digital products

If you take deposits, be careful about how you describe them and when they’re refundable. Consumer law can limit your ability to keep deposits in some circumstances, so it’s worth ensuring your terms are drafted properly for your business model.

Get Your Online And Data Practices Right

If you bill customers through an online account, subscription platform, or you store customer details to manage payment and credit, privacy compliance matters.

A properly drafted Privacy Policy helps set expectations about how you collect, store, and use personal information (including billing and account management data). It also reduces friction when customers ask questions like “why are you still emailing me about this account?”

Train Staff On Credit Control And Communications

If you have a team managing customer accounts, make sure they know:

• when to send reminders and how often
• what they can and can’t say to customers
• when to escalate internally (for example, to management or to legal support)

Having the right internal processes matters just as much as having the right documents. If your staff are unsure, the result is often inconsistent messaging - which can weaken your position if the account in arrears turns into a dispute.

If you employ staff, having clear Employment Contract terms and workplace policies can also help you set expectations around how customer issues (including overdue accounts) are handled and escalated.

Key Takeaways

• An account in arrears means a customer’s payment is overdue, and the longer it goes unpaid, the harder it can be to recover.
• Before chasing payment, confirm the debt, check your contract/terms, and make sure your invoice and records are accurate and complete.
• Use a structured follow-up process: friendly reminder, firmer notice, phone call (with written confirmation), and a documented payment plan if needed.
• If informal follow-ups fail, a formal letter of demand can be an effective next step and helps prepare you for escalation if required.
• Strong contracts, clear payment terms, and consistent systems are your best long-term protection against recurring arrears issues.
• Getting the right legal documents in place early can reduce disputes, support recovery, and help you keep control of customer relationships.
