Invoice reminders on autopilot

We start here because it is the best return in the whole course, and it barely counts as AI. It is a setting you already pay for and have probably never switched on. Turn it on once and it works forever, chasing money you are already owed while you get on with the job.

Why this one first

Late payment is not usually a customer problem, it is a chasing problem. The “sorry to nag, just following up on invoice 218” email is awkward to write, so it goes out late, or never, and your cash flow quietly suffers for your politeness. Automating it removes the awkwardness completely, because the software does the nagging and nobody resents a system.

Every serious UK accounting tool can do this: Xero, QuickBooks and FreeAgent all send reminders on a schedule you set.

Build the sequence

Do not send one reminder, send a short ladder that gets gradually firmer. Here is a sequence that works for most businesses:

• Day the invoice is due: a gentle heads-up. “Just a reminder that invoice 218 is due today, here is the link to pay.”
• Three days after due: a friendly nudge. Same tone, slightly shorter.
• Seven days after due: firmer. “Invoice 218 is now a week overdue, please arrange payment or let us know if there is a problem.”
• Fourteen days after due: a flag for you personally to ring them, rather than another email.

Write the wording once, in your own voice. Keep it human. The goal is to sound like a well-run business, not a debt collector, right up until it needs to be firm.

Set it up

1. In your accounting tool, find invoice reminders in settings (in Xero it is under Email settings and Invoice reminders; QuickBooks and FreeAgent have the same thing under reminders).
2. Turn reminders on and add each step above with its timing.
3. Paste in your wording for each one. Include the payment link or “pay now” button every tool offers, because the easier you make paying, the faster it happens.
4. Set which invoices it applies to. You usually want it on by default for all customers, with the option to switch it off for a specific one.

Before you switch it on

Send yourself a test invoice and let the first reminder fire, or read the preview, as a customer would. Check the tone, check the link works, check your business name and details are right. A reminder with a broken pay link is worse than none.

One judgement call: decide who is exempt. Your biggest account who always pays on day thirty may not want a nudge on day one. Most tools let you exclude a customer while keeping the automation on for everyone else. That five minutes of setup is worth it to avoid annoying your best client.

What good looks like

Once it is running, your overdue list shrinks without you touching it, and the reminders that do go out are consistent and on time instead of sporadic and apologetic. You will still occasionally ring someone on day fourteen, but that is now the exception, not your Friday afternoon.

Roughly fifteen minutes to set up, and it is the closest thing to free money in this course. Next: what happens to the calls you cannot answer, and the simple text that stops them going to a competitor.
