The short answer: automated reminders are worth having and cost nothing, so switch them on first. They handle forgetful payers on a schedule. They cannot tell you which unpaid amount is worth your time this week, or which account has quietly stopped responding. That gap is the point of this guide.
What automation genuinely fixes
Most late payment is not malice, it is memory. A client meant to pay, the invoice slid down the inbox, and a polite nudge a few days after the due date brings it back to the top. Xero and QuickBooks both do this for free: you set the schedule and the wording once, and it runs. For that category, automation is the whole solution, and adding anything more is a waste.
What it doesn’t: the deciding
A schedule treats every account the same. It sends reminder three to the £200 invoice and reminder three to the £6,000 one on the same day, in the same words, from the same address. It has no view of value, no memory of how a particular client pays, and no way to flag the account that has ignored every message and now needs a human. When the schedule ends, the account goes quiet, and quiet is easy to mistake for resolved.

The two things a person still has to do
First, prioritise: of everything outstanding, which single amount is worth chasing this week, weighing value against how late it is and how the client usually pays. Second, write the message that lands when the automated one didn’t, from your own address, in your own voice. Those are the two jobs automation leaves on your desk, and the two that quietly cost the most when they don’t happen. How to write that message is covered in chasing a late payment politely.
The practical setup
Turn on your accounting platform’s reminders for the routine cases. Then put the deciding on a system too, so the one account that needs you this week surfaces on its own instead of relying on your memory between billable jobs. Kelo does exactly that from a read-only connection, see how it connects to Xero or QuickBooks. For the wider picture, the full guide to getting paid puts reminders in their place alongside everything else.
