Going after delinquent customers can hurt the business’s financial well-being and drain time. That’s where automated invoice emails come in—quick, consistent messages sent straight to your clients as soon as payment is due.
But not all invoice emails work the same. A well-crafted message can make the difference between being paid on time and being ignored. In New Zealand, where late payment fees must comply with the Fair Trading Act and Credit Contracts and Consumer Finance Act, the tone and content of your invoice emails matter.
You need to be clear, polite, and firm, without crossing legal lines.
In this article, we share four effective invoice email templates designed to help Kiwi businesses get paid faster. Use them to improve your communication, strengthen client relationships, and recover payments with less stress.
Things to Avoid When Writing an Invoice Email Template
Writing a clear and professional invoice email is vital for timely payments and maintaining good client relationships. It’s also important to follow local debt collection laws to keep clear from disputes or compliance issues.
Avoid these common mistakes when crafting your invoice email template:
- Missing Key Information. Leaving out the due date, invoice number, or payment terms can cause confusion and delay payment. State these details clearly and upfront.
- Using Vague Language. Avoid unclear phrases like “as discussed” or “for services rendered.” Specify the services or products provided and the exact amount due.
- Being Too Casual or Aggressive. Using an overly relaxed tone may lead clients to deprioritise your invoice. On the flip side, aggressive wording can harm your business relationship and may not align with fair debt recovery guidelines under New Zealand law.
- Skipping a Follow-Up Reminder. Don’t rely on a single email. A well-worded follow-up is standard practice and supports your rights under the Fair Trading Act.
- Attaching Unsecured Documents. Always use secure formats like PDF to prevent unauthorised edits or confusion over the original content.
