Cashflow
Prepaid packs vs casual sessions
A pack and a casual session can bill the same amount in a year and produce completely different businesses. One gives you a predictable week and a debt you owe in sessions; the other gives you flexibility and a diary that empties whenever life gets busy.
Packs win for the trainer, in almost every case. You are paid before you deliver, cancellations drop sharply because the client has already committed money, and your week stops depending on who happens to feel like showing up.
The catch is the part nobody mentions: a pack is a liability. The cash is in your account, but the sessions are still owed. If you do not track what is outstanding, you will spend money you have not earned yet — and the bill arrives as a month where everyone is training and almost nothing is coming in.
What each model actually does to your week
| Prepaid packs | Casual sessions | |
|---|---|---|
| Cashflow | Lumpy but front-loaded | Smooth but thin |
| Cancellations | Much lower — money is committed | Higher, especially in winter |
| Admin | Track balances and expiry | Chase payment every week |
| Client commitment | High — they have decided already | Renewed every single week |
| Your risk | You owe sessions you have been paid for | Your income restarts from zero weekly |
| Best for | Established books, goal-driven clients | New clients, trials, irregular schedules |
Read that table as a description of risk, not convenience. Casual pricing pushes the risk onto you: every week your income restarts at zero and has to be rebuilt by other people's decisions. A pack moves that risk to a decision the client already made.
The pack trap: money you have already spent
Here is the failure that catches good trainers. In January you sell six ten-packs. Cash looks excellent, so the January numbers look like a great month and you spend accordingly. In February and March you deliver those sixty sessions — genuinely busy, genuinely working — and almost no new money comes in, because everyone is training on credit they already bought.
Nothing went wrong. The business is healthy. But if you read January as profit rather than as sixty sessions of debt, February feels like a catastrophe and you will make a bad decision because of it — usually a discount you did not need to offer.
If every client stopped training tomorrow, how much would you owe them? Not in refunds — in sessions you have been paid for and have not delivered. That number is your real pack liability, and most trainers have never calculated it once.
Sizing a pack so it actually gets used
A pack only works if it is finished. An unfinished pack is a client with a guilty balance, which is one of the more reliable ways to lose someone quietly — they stop coming and cannot face the conversation about the sessions they wasted.
- 5 sessions — a fortnight or so at twice a week. Ideal for new clients and for anyone whose schedule is unpredictable.
- 10 sessions — the standard for a reason. About five weeks at twice a week: long enough to see change, short enough to stay visible.
- 20 sessions — only for clients with an established habit. It is a big cheque and a long horizon, and it is the size most likely to be abandoned half-finished.
Expiry dates are worth setting, and worth being flexible about. The date exists to create gentle urgency, not to take someone's money — and enforcing one rigidly on a client who was unwell buys you a bad story that travels further than the sessions were worth.
When casual is genuinely the right answer
Packs are not universally correct, and pushing one too early costs you clients.
- A first session. Nobody should be asked for ten sessions of commitment before they know whether they like training with you.
- Genuinely irregular clients. Shift workers and people who travel for work will not finish a pack, and giving them one sets up the guilty-balance problem.
- Winding down. A client moving from twice a week to once a month is still worth having. Forcing a pack on them ends it entirely.
A useful default: casual for the first two or three sessions, then offer a pack once both of you know it is working. The offer lands better after proof than before it.
Tracking the balance is the whole job
Everything above collapses to one requirement: you need to know, at any moment, how many sessions each client has left and what that adds up to across your book. Trainers who run packs on memory eventually make one of two mistakes — delivering sessions that were never paid for, or losing a client over a disputed count that neither party can prove.
Momentum keeps the pack balance live
Every ticked session deducts from that client's pack automatically, the roster shows who is running low before they run out, and the dashboard totals what you owe across every client — the answer to the question above, without you calculating anything.
It also means the awkward conversation never happens: the count is recorded as you go, visible to you, and consistent with what the client was invoiced.
Common questions
Are prepaid packs better than casual sessions for personal trainers?
For the trainer, in most cases yes. You are paid before you deliver the work, cancellations drop sharply because the client has already committed money, and your week stops depending on who decides to show up. The trade-off is that a pack creates a liability — the cash is yours but the sessions are still owed — so it only works if you track what is outstanding.
How many sessions should a personal training pack contain?
Ten is the common standard because it is roughly five weeks at twice a week: long enough for the client to see change, short enough that the pack stays front of mind and actually gets finished. Five-packs suit new or unpredictable clients, and twenty-packs should be reserved for people with an established habit, because they are the size most often abandoned half-used.
Should personal training packs have an expiry date?
Setting one is worth it, and enforcing it rigidly usually is not. The date exists to create gentle urgency so the pack gets used rather than drifting, which serves the client as much as you. Being flexible when someone has been genuinely unwell or away costs you very little and avoids a bad story that will travel much further than those sessions were worth.
Is money from a prepaid pack income straight away?
Commercially it is money you have received but not yet earned, because you still owe the sessions. That is why reading a big pack month as profit is the classic trap: the following months look empty even though you are busy delivering. How that money is treated for tax and reporting depends on your circumstances and how you account, so confirm your own position with a registered tax or BAS agent.
What happens if a client wants a refund on unused sessions?
Decide your policy before it comes up, write it down, and say it out loud when you sell the pack. Whatever you choose, being able to show exactly how many sessions were delivered and when is what keeps the conversation short — a disputed count that neither side can evidence is far more damaging than the refund itself.
