What Most Owners Try First, and Why It Stops Working

Most business owners start with generic email templates or send reminders manually. While this might work initially, it quickly becomes unmanageable as your client list grows. Sending the same email template to every client can make your reminders less effective, as clients might start ignoring them altogether.

What to Do Instead, as Concrete Steps

Take a few hours to create personalized email templates. Tailor each message to the specific context of the invoice, whether it's a monthly retainer, a project completion, or hardware payment. Schedule these emails to go out at regular intervals after the invoice is issued. This personalized approach can help ensure your messages are read and acted upon.

How This Gets Easier When the Follow-Up Runs on a Schedule

Once you’ve set up these templates, the heavy lifting is done. Approve your batch of reminders each month, and let them send automatically. This way, you’re not tied to your inbox, chasing payments daily. Plus, nothing goes out after an invoice is paid, so you won’t accidentally annoy a client who’s already squared away.

FAQ

How often should I send invoice reminders?

Send an initial reminder a week before the due date, follow up on the due date, and then send reminders weekly if it becomes overdue.

Can I use these templates with any email client?

Yes, just copy and paste them into your email platform. Adjust the placeholders with your client's specific information.

What if a client disputes an invoice?

Pause any reminders for that invoice. Reach out personally to resolve the dispute. Clear communication is key.

Do I need special software to send these reminders?

No, you can send them manually via email. However, using a service like ARPilot can automate the sending process, making your life easier.

Will these templates work for other industries?

They’re tailored for ongoing MSP and IT client relationships but can be adapted for other service-based businesses with similar client interaction.
