Your fee structure decides when parents think about leaving. A per-term invoice puts that question in front of every family four times a year, and the parent answers it with whatever they've seen since the last one.
The invoice is a decision point
Most centres bill by the term. Ten weeks in advance, one invoice, due before week one. It's sensible: it matches the school calendar, it's easy to reconcile, and it gives you the cash before the term starts.
It also creates a moment. Four times a year a parent opens an email with a dollar figure in it and asks the only question that matters to them: is this worth it? They answer it in about thirty seconds, with whatever evidence is to hand.
For most centres that evidence is the last invoice, a school report the centre didn't write, and a child who says "fine" when asked. Against that, the invoice is a bill, and a bill is something you can decide not to pay.
Monthly direct debit spreads the moment out. The decision is smaller and more frequent, and it tends to get made at the same time anyway: January, when the debit for a term nobody's started yet lands. The mechanism is the same. What differs is how many times a year you get to put proof in front of it.
Nothing about this is wrong with per-term billing. The problem is what arrives before it, which is usually nothing.
Four moments, and the two that count
Not all four invoices are equal.
| Invoice | What the parent is weighing | What makes it easy |
|---|---|---|
| Term 1 | Whether to restart after six weeks off | A booked slot, a confirmed start date, a note about week 1 |
| Term 2 | Whether the first term did anything | The first written proof of progress |
| Term 3 | Habit, mostly | A report they've started to expect |
| Term 4 | Whether to commit to next year | A term summary that names what improved |
The Term 4 invoice is the one where the whole year is on the table, because it travels with the re-enrolment form. But the Term 1 invoice is the one that quietly loses the most families, because it arrives after the longest silence. A parent who has heard nothing since November is being asked to restart, not continue, and restarting is a bigger decision.
If you only change one thing about your billing, change what goes out before Term 4 and Term 1.
Proof before the invoice, not with it
Here's the pattern that works, whatever your fee structure: the parent reads something about their child before they read a dollar figure.
Two weeks before the invoice, send the progress note. One page. What their child worked on this term, what got better, specifically, and what's next. Not "Arjun is doing well". "Arjun's accuracy on two-step word problems went from about one in three to three in four, which is the skill we spent three Wednesdays on." Sign it with your name.
Then the invoice, with a one-line reminder of what the note said. Then the deadline, with a reason: "so I can hold his Wednesday spot."
The order is the whole trick. A parent who has just read that a named skill doubled is reading the invoice in a different mood from a parent who has opened a bill cold. The re-enrolment email templates have this sequence written out, including the version for the parent who has been quiet all term.
If you send a fortnightly report through the year, the note before the Term 4 invoice is a summary of twenty reports the parent has already seen. If you don't, it's the first written word they've had from you that wasn't a bill. Either way, it goes first.
Confirm the Term 1 slot in writing
The re-enrolment form says yes. That's not the same as being enrolled.
A family with a signed form and nothing else has an intention. A family with a signed form, a confirmed class, a named day and time and a start date has a booking. Bookings survive January. Intentions don't.
So in the last week of Term 4, every returning family gets one short message: "Confirming Maya in Year 6 Maths, Tuesdays at 4:30, starting 3 February. See you then." Written, not said at the door. A parent forwards it to the other parent, it goes on the fridge, and in late January when the routine has gone and the child is grumbling, there's a specific thing to not cancel rather than a vague thing to not restart.
The Term 4 retention playbook puts this on the calendar with everything around it. The confirmation is the last line before the holidays.
What it's worth
If a dozen families don't come back after Term 4, a year of their fees walked out over a summer, and most of Term 1 goes on replacing it. The retention cost calculator does that arithmetic with your own figures.
The billing change itself costs nothing. It's a note two weeks earlier and a confirmation one week later. A few retained families pays for a platform that sends the note every fortnight. The by-hand version costs an afternoon.
What to do this week
Find the date your Term 4 invoices go out. Move the progress note to two weeks before it. Draft the confirmation message for the last week of term, with a blank for the class, day, time and start date. If you'd rather the note wrote itself from the work your students actually did, from your own material, that's what the fortnightly report is for.
