How to automate invoice chasing (without upsetting good customers)

The short answer: Set a reminder schedule that starts before the due date, write short messages in your own tone, send them by email and text automatically from your accounts data, and escalate to a person only when an account stays overdue. Stop the moment payment lands.

Key points

  • Start before the due date, so the first message is helpful.
  • Keep messages short, with one clear way to pay.
  • Firm up the tone gradually.
  • Stop automatically when they pay.
  • Escalate to a person, not another email.

Step 1: set the schedule

Start before the due date. A reminder three days before reads as helpful, not pushy, and it catches the invoices that would otherwise be paid late by accident.

Step 2: write the messages

Before it’s due

Hi Jo, a quick heads-up that invoice 4521 for £[amount] is due on Friday. A copy’s attached. Any questions, just reply.

On the due date

Hi Jo, invoice 4521 is due today. You can pay here: [link]. Thanks.

A week overdue

Hi Jo, invoice 4521 is now a week overdue. Could you let us know when it’ll be paid, or if there’s a problem with it?

Short, specific, one clear next step. No threats, no essays.

Step 3: connect it to your accounts data

The reminders need to know what’s been invoiced, when it’s due and when it’s been paid. That comes from your accounts package. Connected properly, reminders go out on time and stop the moment payment lands.

Step 4: escalate to a person

If an account is still overdue after the automated reminders, another email won’t help. Alert a manager and create a call task. That’s where a conversation works.

Step 5: chase applications too

If you sell on trade accounts, chase unfinished applications the same way. A customer who never finished their form can’t buy on account.

Questions people ask

How many invoice reminders should I send?

Two or three automated reminders is usually enough: one before the due date, one on it, and one a week later. After that, a person should pick up the phone.

Should invoice reminders be by email or text?

Email for the invoice and detail, text for a short nudge that actually gets seen. Using both works best.

Is it OK to send automated payment reminders?

Yes. Reminding a customer about an invoice they owe is a normal service message. Keep it polite and in your name.
