Starting out
What to track in your first year
Your first year produces the only data that will ever describe how your business actually started. Almost every trainer loses it, then spends year two guessing at questions the records would have answered in seconds.
Track five things from your first week: sessions delivered, money received, money owed to you, what it cost you to earn, and why clients left. That is the whole list.
Everything else — social followers, session photos, elaborate spreadsheets of programming variables — is either someone else's metric or something you will never look at again.
The five things worth recording
1. Sessions delivered, by client, by week
The foundation everything else is calculated from. Recorded as you go it takes seconds; reconstructed at tax time from a calendar and memory it is hours of work and still wrong. It is also your only defence in a disagreement about how many sessions a client has used.
2. Money in, and what it was for
Not just the amount — what it paid for. A $900 transfer might be a ten-pack, three months of weekly training, or a lump sum covering two clients. Six months later the bank statement cannot tell you which, and the difference matters for working out what you still owe.
3. What is owed to you
Two separate numbers that both matter: invoices sent and unpaid, and sessions delivered but never invoiced. The second is the one that quietly costs new trainers the most, because nothing prompts you about work you simply forgot to bill.
4. What it cost you to earn
Floor fees, rent, insurance, registration, equipment, travel, phone, software. Keep the receipts as you go rather than hunting for them at the end of the year — whatever you can or cannot claim is a question for a registered tax or BAS agent, but you cannot claim anything you cannot evidence.
5. Why clients stopped
One line each time. "Moved suburbs." "Money got tight." "Never really committed." After a year that list is the most valuable page in your business, because a pattern in it tells you something no amount of new marketing will fix.
What is not worth tracking
New trainers often over-record, which is its own failure mode — an elaborate system that gets abandoned in March tells you less than a simple one kept all year.
- Follower counts. Unless you can name a client who came from there, it is a number that feels like progress without being any.
- Every programming variable. Track what your clients need to progress, not what would make an interesting spreadsheet.
- Daily revenue. Too noisy to mean anything. Weekly is the smallest unit that tells you something real.
- Anything you have to remember to update. If it is not captured as part of doing the work, it will not survive a busy month.
The questions this answers in year two
The reason to bother is that year two asks specific questions, and they are answerable in seconds or not at all:
- Which month is genuinely your quietest, so you can plan around it rather than being surprised annually?
- What is your real average weekly income, as opposed to your memory of a good week?
- How long does a typical client actually stay, and how much is one worth over that time?
- Which clients are worth more than they look, once travel and unpaid time are counted?
- Can you afford to raise your rate, drop a venue, or go full-time?
None of these can be answered from a bank statement, because a bank statement records amounts without recording what they were for. That context has to be captured at the moment the money moves, or it is gone.
Start simple, and make it survive March
A notebook genuinely beats an abandoned system. The test of any approach is not how complete it is in week one but whether it is still being kept in month six, when you are busy and tired and it feels like admin.
That is why the recording has to sit inside the work rather than beside it. Anything that requires a separate weekly session at a laptop will lose to a full day of clients, every time.
Built so the record keeps itself
Momentum Tracking is designed around one action: tick a session when it is done. Revenue, what is owed, pack balances and your tax estimate all follow from that single tap, so the record is a by-product of doing the work rather than a separate job.
Which means that in year two the questions above are already answered — you are reading your business rather than reconstructing it.
Common questions
What records should a new personal trainer keep?
Five things, from your first week: sessions delivered by client and week, money received and what it paid for, what is still owed to you, what it cost you to earn, and a one-line note each time a client stops. That set answers almost every question your second year will ask. Requirements for tax record keeping are a separate matter and worth confirming with a registered tax or BAS agent.
Do I need accounting software in my first year as a PT?
Not necessarily, but you do need something you will still be using in month six. General accounting packages are built around invoices and bank feeds rather than sessions and packs, which is why many trainers end up keeping a parallel spreadsheet anyway. The test is whether the recording happens as part of delivering the session, because anything that needs a separate weekly admin block tends not to survive a busy month.
How do I keep track of how many sessions a client has left?
Deduct from the balance at the moment the session happens, not later from memory. The failure mode is uniform: a client believes they have three sessions left, you believe they have one, and neither of you can evidence it. Recording the deduction as you go keeps the count accurate and means the conversation never has to happen.
What is the most common record-keeping mistake new trainers make?
Building something too elaborate to maintain, then abandoning it around March. A simple record kept all year is worth far more than a detailed one kept for eight weeks. The second most common is recording amounts without recording what they were for, which leaves a bank statement that cannot tell you whether a payment was a pack, a block of weekly sessions, or two clients paying together.
Should I track why clients leave?
Yes, and it costs you one line each time. After a year that list is the most useful page in the business, because the reasons cluster: if most departures say money got tight, that is a pricing and packaging question, and if most say they got too busy, that is a scheduling one. Neither pattern is visible while the reasons live only in your memory.
