Most payment problems can be traced to a gap or error in the commercial cycle — a quote that was never formally accepted, an invoice that went to the wrong email, a statement that was never sent, a reminder that came too late. This guide maps the full cycle and explains what each step must achieve to make the next one easier.

Stage 1: The quote

The quote is the commercial agreement that precedes the invoice. Without a clear, accepted quote, the invoice may be disputed.

What a good quote contains

Your entity name and ABN — so the client knows who they are contracting with
The scope — exactly what is included and (if relevant) what is excluded
The price — total amount, whether GST is included or excluded, and any variable components
Payment terms — your standard terms: e.g. "50% deposit on acceptance, balance on completion, due 14 days from invoice"
Validity period — e.g. "This quote is valid for 30 days"
Acceptance mechanism — "Please reply to this email to accept" or a signature field

Getting the quote accepted

Written acceptance is the foundation of the contract. "Sounds good, let's go ahead" by email is sufficient. A signed quote is better. Without any written acceptance, the terms of your quote may not be enforceable — including your payment terms.

Tip: For jobs over $5,000, include a brief line in the acceptance confirmation: "By accepting this quote, you agree to the payment terms and conditions outlined above." This pre-empts disputes about what was agreed.

Stage 2: The tax invoice

The invoice is the demand for payment. It should be issued as soon as the trigger event occurs — delivery of goods, completion of the milestone, or the billing date for a recurring arrangement.

The link from quote to invoice

Reference the quote or proposal number on the invoice ("Re: Quote REF-20260601")
Match the description and amount to the accepted quote — changes should be documented as approved variations
Use the same entity name as on the quote
Send to the accounts payable contact confirmed at the time of quote acceptance

Stage 3: The account statement

An account statement is not a replacement for an invoice — it is a summary of the account. It lists all invoices, credits and payments for a period, with a running balance and outstanding total. It should be issued:

Monthly for any credit customer with an ongoing account
On request when a client queries their balance
When chasing overdue amounts — a statement alongside a firm reminder shows exactly what is owing and when each invoice became overdue

Why statements matter

A monthly account statement keeps your business front-of-mind in the client's accounts payable process. It also creates a documented record of what was outstanding at each point in time — useful if the debt is later disputed or referred for recovery.

Stage 4: The reminder sequence

Begin the reminder sequence on day one of overdue — not after weeks of hoping the client will pay unprompted. The sequence:

Day 1–3: Friendly nudge: Assume oversight. Short, friendly email. Include the invoice number, amount and due date. Attach the invoice and statement as PDFs. Most overdue invoices are resolved at this stage.
Day 7–14: Firm reminder: More direct tone. Reference the previous reminder. Set a clear deadline (7 days). Note that your late-payment interest clause applies if the amount was in your terms. Attach the statement.
Day 21+: Final notice: Explicitly state this is the final notice before escalation. Name the escalation: "If payment is not received by [date], we will refer this matter to a commercial debt recovery specialist." Give a firm deadline of 7 days.

Use our free payment reminder templates for ready-to-copy email and letter text at each stage.

Stage 5: Debt recovery

If the full reminder sequence — including the final notice — has not produced payment, the next step is external recovery. Internal chasing beyond this point rarely works and consumes your time.

What to prepare before referring

Copy of the accepted quote or signed contract
Copies of all tax invoices
The account statement showing all transactions
Copies of all reminders sent and any responses
Any purchase orders or delivery receipts (proof of supply)

When to refer

Under 90 days: The best time to refer. Recovery rates are highest on fresh debts. Many debtors pay on first contact from a specialist, before any formal action is required.
90–180 days: Still very recoverable. Don't let it go longer than this hoping for a self-cure.
Over 12 months: Harder to recover, but still possible depending on the circumstances. Refer as soon as you decide to act — waiting longer never helps.

Common gaps in the workflow — and how to close them

Quote accepted verbally, not in writing: Send a confirmation email immediately after verbal acceptance: "As discussed — I'll proceed on the basis of Quote REF-X. Payment terms are 14 days from invoice. Let me know if you have any questions." Get a reply.
Invoice sent to the wrong contact: Before invoicing, confirm the accounts payable email at the time of quote acceptance. Add it to your client file. Send to accounts payable, not the project manager.
No statement sent to credit customers: Set a calendar reminder for the first business day of each month. Generate and send statements to all credit accounts, regardless of whether they are overdue.
Reminders sent too late: Start on day one. Waiting two weeks to send the first reminder means the client knows they can pay late with minimal consequence.
Recovery referral delayed too long: If three reminders have not worked, the next escalation must be external. Do not send a fourth or fifth reminder — refer the debt.
