I Have 5 Clients and $30/Month. What PT Software Should I Use?

You do not need Mindbody

You finished your Cert IV. You have 3, 5, maybe 8 clients. You are running sessions out of a gym, a park, or a shared studio space.

Right now your business runs on WhatsApp, PayPal, and a Google Sheet that is getting harder to manage every week. It works. Barely. But you spend Sunday nights copying and pasting programs, chasing invoices on Tuesday, and wondering if that client who went quiet last week is coming back.

You Google "best PT software" and every result is either a $129/month enterprise tool or a comparison article built for studio owners with 50+ clients. That is not you. Not yet.

So what actually makes sense when you are small, budget-conscious, and growing?

What you actually need at this stage

Forget feature lists for a second. At 5 clients, your problems are specific:

You need to stop chasing payments. Invoicing manually through PayPal or bank transfer works until someone forgets. Then you are texting them about money, which is awkward, and it takes time you could be coaching. Automated billing fixes this. The client's card gets charged. You get paid. Nobody has an uncomfortable conversation.

You need scheduling that does not involve texting. Every "hey are you free Thursday at 4?" text takes 5 minutes of back and forth. Multiply that by 5 clients changing times every week and you have lost an hour before you have coached anyone. Self-serve booking means clients pick a slot. You confirm. Done.

You need to build programs faster. A Google Sheet program takes 30 to 60 minutes per client if you are being thorough. At 5 clients that is up to 5 hours a week. At $80/hour, that is $400 in coaching time spent on admin. AI program generation does the first draft in seconds. You review, adjust, and assign.

You need to know who is losing interest. At 5 clients you can probably feel when someone is drifting. At 15 or 20, you cannot. Engagement scoring catches the pattern before the cancellation text arrives.

What you do not need (yet)

You do not need a marketplace to discover new clients. You have 5. Word of mouth and Instagram are working. You do not need multi-location management. You have one location (or none). You do not need a dedicated front-desk tool, because you are the front desk.

Most enterprise software is priced for the problems you do not have. You end up paying $100+/month for a scheduling system and ignoring the 30 features built for a gym chain.

The real options under $50/month

If your budget is $30/month and you need billing, scheduling, and programming in one place, your options narrow fast.

Trainerize starts at ~$14 AUD/month for 2 clients, but billing costs an extra ~$14/month and scheduling another ~$36/month. A trainer with 5 clients on the Pro 5 plan with billing and scheduling is looking at ~$81/month. The gap between the advertised price and the real cost is worth checking before you sign up.

TrueCoach starts at ~$43 AUD/month for 5 clients. Good for program delivery. Now includes free automated payments. But scheduling is limited, there is no engagement scoring, and you will need other tools to fill the gaps.

PTminder starts at $88 AUD/month for up to 50 clients. Solid scheduling and billing. No AI. Good if you only need the basics, but that is a lot of money when you have 5 clients generating $400 to $800/week.

BuildStability starts at $6 AUD/month for up to 6 clients. The Starter plan is $30/month for up to 25 clients. All core features are included at every tier: scheduling, billing, AI program generation, engagement scoring, churn prediction, session notes, and an AI assistant that queries your actual business data. Tiers differ by client count and AI request limits. No add-ons. No per-client fees. Standard Stripe processing fees apply on client payments.

We are obviously biased. We built it. But the pricing is public and the maths is simple: $30/month for a tool that replaces PayPal, Calendly, Google Sheets, and the Sunday night programming grind. BuildStability was built by a CPA who started in public practice, then spent 25 years building accounting and financial software for Australian businesses. Start a free 14-day trial and see if it fits. No credit card required.

Our first 10 founding trainers get 25% off for life (for as long as you maintain an active subscription on the same plan — does not carry over to plan changes) plus 6 months of unlimited AI access on any plan. Strictly limited to 10 spots. Use code FOUNDING10 at checkout.

Do the maths on your "free" stack

The tools you are using now feel free. They are not.

If you spend 5 hours a week on admin (invoicing, scheduling texts, building programs, chasing no-shows) and you charge $80/hour, that is $400/week in coaching time you are giving away. Over a month, $1,600. Over a year, more than $20,000.

Software that costs $30/month and saves you even half of that admin time is the cheapest investment you will make this year.
