A three-message reminder sequence for unpaid invoices, plus the automation settings that send it for you so you don't have to chase anyone.
Chasing a $600 invoice from a customer in Hartland feels awkward. Even when you did the work well. A simple, steady reminder sequence takes the awkwardness out of it.
Why most contractors chase payment badly
The usual pattern looks like this. You do the job. You send an invoice. You wait. Nothing happens. A few weeks later you remember and send an annoyed text. That's when things get tense. It feels personal instead of routine.
The fix isn't being more aggressive. It's being more consistent. Use the same schedule for every customer. Then no one can take it personally.
The three-message sequence
Here's a simple structure that works for most trades:
- 01Day of invoice: A friendly note that the invoice went out. State the amount and due date clearly.
- 023 days after due date: A short, neutral reminder. No apology, no attitude, just the facts.
- 0310 days after due date: A firmer message that names a next step, like a late fee or a pause on future work.
Here's roughly how each one should sound.
Message 1: "Hey, here's the invoice for the job on [date], total is $[amount], due [date]. Let me know if you have any questions."
Message 2: "Quick reminder, invoice for $[amount] was due [date]. Let me know if you need me to resend it."
Message 3: "This invoice is now 10 days past due. A $[amount] late fee applies after [date] per our agreement. Happy to help if there's an issue with the invoice."
Why tone matters more than timing
None of these messages are angry or guilt-heavy. Notice that. Customers who are going to pay usually just need a nudge. An aggressive tone can turn a slow payer into a defensive one. Save the firmer language for the third message. Even then, keep it factual, not emotional.
Put a late fee in your contract, not just your reminder
A late fee only works if the customer agreed to it upfront. Add a line to your standard contract or invoice terms: "Invoices unpaid after 10 days are subject to a [X]% late fee." Wisconsin doesn't set a fixed cap on this the way some states do. But a fee in the 1-2% per month range is common and defensible.
Automate the sequence instead of remembering it
The real problem with invoice chasing isn't knowing what to say. It's remembering to say it on time while you're out running jobs. Most invoicing software, like QuickBooks or Jobber, lets you schedule automatic reminders on this exact timeline. Our guide on how to automate invoice reminders walks through the setup. The messages go out without you touching anything.
Once it's set up, every invoice gets the same treatment. No one gets forgotten. No one gets a harsher tone because you were in a bad mood that day.
What to do when someone still doesn't pay
If the third reminder passes with no response, try a phone call instead of another text. Keep it short: "Hey, I noticed the invoice from [date] is still open, is everything okay on your end?" Most of the time there's a simple explanation. A lost email or a forgotten reminder on their side.
If a customer goes fully silent after that, decide your next step ahead of time. Options include a formal notice, a collections service, or small claims court. In Wisconsin, small claims covers amounts up to $10,000. Knowing your own line ahead of time keeps you from giving up too easily or escalating too fast.
Keep records of everything
Save every invoice, every reminder, and every response. Even the friendly ones. If a dispute ever goes further, whether that's small claims or just a disagreement about what was owed, a clean paper trail settles it fast.
Offer a payment plan before it gets to collections
Some customers are struggling, not avoiding you. For them, a short payment plan can get you paid faster than a rigid all-or-nothing stance. Splitting a $1,200 invoice into three payments over six weeks beats chasing the full amount for three months. It also beats writing it off entirely. Put the plan in writing. Even a quick text confirming the dates and amounts works. That way there's no confusion later.
Watch for repeat slow payers
Some customers pay every invoice late, every time, no matter how many reminders you send. Once you notice the pattern, change how you work with them. Require a deposit upfront. Shorten your payment terms. Or ask for payment on completion instead of sending an invoice at all. You're allowed to treat repeat offenders differently than everyone else.
Questions people ask
How long should I wait before sending the first reminder?
Send the first message the same day the invoice goes out. It's not a reminder yet, just confirmation. It sets the expectation that you track this closely.
What if a customer disputes the invoice instead of paying?
Pause the reminder sequence and deal with the dispute directly. An automated late notice during an active dispute usually makes things worse, not better.
Should I stop taking new jobs from a slow-paying customer?
It's reasonable to require payment upfront or a deposit before booking that customer again. You don't have to explain your reasoning in detail. Just adjust your terms for them going forward.
