How do you chase an unpaid invoice without sounding rude?

A short, friendly written message works better than a phone call almost every time. Keep it direct, assume the best about your client, and make it easy for them to act. No guilt trips, no passive-aggressive wording — just a plain reminder with everything they need to pay you.

Most people don't pay late because they're trying to dodge you. They got busy, the invoice got buried, or they genuinely forgot. Keeping that in mind changes how you write the message, and that tone is what gets you paid faster.

Why is chasing invoices so uncomfortable, and how do you get past it?

A lot of small business owners, especially tradies and service providers, hate this part of the job. You did good work, you shouldn't have to beg for the money. That feeling is completely valid, and it's also exactly what stops people from following up early enough.

The trick is to reframe it. You're not chasing someone down or being a pest. You're running a business, and getting paid on time is a normal, professional expectation. The awkwardness mostly lives in your head — clients are rarely as bothered by a polite follow-up as you think they'll be.

Following up in writing also removes the live discomfort. There's no stumbling over words, no reading their face, no uncomfortable silence on the phone. You write it once, send it, and let it do the work.

What should you actually say in a payment reminder message?

Keep it short. One or two sentences is enough for a first reminder. Something like:

• First reminder (a few days after the due date):**
  "Hi [Name], just a quick reminder that invoice #[number] for $[amount] was due on [date]. Let me know if you have any questions — happy to help get this sorted."
• Second reminder (around a week later):**
  "Hi [Name], following up on invoice #[number] — we haven't received payment yet. Could you let us know when we can expect it? Details are in the invoice attached."
• Third reminder (if it's been a few weeks):**
  "Hi [Name], this is the third time I'm reaching out about invoice #[number] for $[amount], now [X] days overdue. Please arrange payment by [date] or get in touch so we can work something out."

Notice how the tone shifts slightly with each message. The first one is warm and assumes a simple oversight. The second is still friendly but more direct. The third is firm and sets a clear deadline, without being aggressive.

**A few things to always include:**
- The invoice number and amount
- The original due date
- A copy of the invoice or a direct link to it
- One clear action for them to take

Don't make them hunt for the details. The harder it is to find the invoice, the longer it takes to get paid.

Should you call or message when chasing an invoice?

For most situations, a written message — SMS, email, or even a WhatsApp — is the better first move. It gives the client something to act on immediately, at a time that suits them. A phone call can put people on the spot, and if they're not near their computer or bank details, you're not getting paid in that moment anyway.

Calling does have a place. If someone has gone completely silent after two or three written follow-ups, a quick, calm phone call can break the deadlock. Keep it short: "Hey, just checking in on that invoice I sent over — did you get my messages?" Then stop talking and let them respond.

The goal isn't to corner anyone. It's to remove whatever obstacle is in the way of them paying you.

How can automation help with unpaid invoices, without losing the personal touch?

This is where a lot of service businesses quietly fix the problem for good. Setting up an automated follow-up sequence means the reminder goes out on time, every time, without you having to remember to do it or psych yourself up to send it.

The message still sounds like you. You write it once in your own voice, and the system sends it at the right interval after the due date. Your client gets a friendly nudge, you don't have to think about it, and the money comes in sooner.

At LIP Services, this is one of the things we set up inside our automated CRM systems for service businesses. Robert, our founder, came from a tradie background — he knows what it's like to be owed money and hate the idea of making the call. The whole point of automating this stuff is so you're not relying on your own mood or memory to keep cash flowing.

You don't have to be tech-savvy to run it. You just have to be willing to set it up once.
