# The due-date reminder routine

> Runs at 08:00, warns three days ahead — and there are two conditions that make it warn nobody at all.

## What you will get

A clear picture of when the reminder goes out, to whom, and why it may simply not
be going out at your school.

## The rule

**At 08:00, the system warns every student with an instalment due in three days.**

The email arrives with the subject *Reminder: instalment due in 3 day(s)*, with the
school's name.

It is the best-performing email of all: it arrives while there is still time to
pay, and the subject states the urgency without needing to be opened.

## Three days, and only three

**The lead time is fixed at three days.** There is no field in Settings to change
it.

Do not confuse it with **Days before due date to issue**, on the Billing tab: that
one controls when the *charge* is issued; this is the reminder, and it is a
different number — one you do not choose.

At a school issuing 5 days ahead, the sequence is: charge issued 5 days before,
reminder 3 days before, arrears notice 1 day after.

## The two conditions that silence the reminder

**1. The school must have the receiving service connected.** The routine begins by
looking for schools with a receiving connection configured; **those without are
skipped entirely** — even though the reminder is just an email and would not need
it.

In practice: a school still registering payments by hand **sends no reminders at
all**, and nothing on screen says so. Logged for correction.

**2. The student must have an email.** With none on the record there is no access
account and nowhere to send it.

## What it does not do

- **It does not warn twice.** One reminder per instalment, three days ahead. No
  daily countdown.
- **It does not warn about already-overdue instalments.** That is the other
  routine.
- **It does not warn about paid, waived or cancelled instalments.**

## How to check it is working

Take a student with an instalment due in exactly three days and confirm the next
day whether they received it. If not, test the two conditions above in that
order — the first accounts for most cases.

## If something goes wrong

> [erro]
> **No student receives reminders.** Almost always the first condition: the school
> has not connected the receiving service yet.
>
> **Only some receive them.** Those are the ones with an email on file. Check who
> is missing one.
>
> **The school wanted a week's notice.** Not configurable today. What you can
> adjust is the charge issuing lead time, on the Billing tab.
