Do fitness businesses need billing software?

Yes, the moment you have more than 10 regular clients. Class pack tracking and monthly membership billing cannot be managed reliably without software.

Can I sell class packs that expire after a set period?

Yes. Class packs have a configurable expiry window (e.g. 8 weeks, 3 months). Credits that aren't used by the expiry date are voided automatically.

Can I have multiple membership tiers with different class allowances?

Yes. Create as many tiers as you need, each with a specific class access level. The booking portal enforces each member's allowance automatically.

Can I take payment before the first personal training session?

Yes. Session packs are paid upfront via Stripe before any session is booked. Total payment before first contact is fully supported.

Can I freeze a member's account when they go on holiday?

Yes. Enable membership pausing. Members can pause for 1–4 weeks. Billing and class access resume automatically when the pause ends.

What happens when a class pack runs out mid-month?

The booking portal blocks new class bookings when credits are exhausted. The member receives an automatic notification with a link to purchase the next pack.

Can I offer discounted annual memberships paid upfront?

Yes. Annual memberships billed as a single Stripe payment at a discount vs monthly billing are fully supported.

What is Fitness Business Billing Software?

Fitness billing software replaces the awkward end-of-session payment conversation, manual class pack tracking, and the income uncertainty of one-off client billing.

✓ Bills monthly gym or PT memberships automatically via Stripe
✓ Sells class packs (e.g. 10 classes) paid upfront
✓ Tracks session and class credits per client
✓ Sends automated receipts and membership renewal reminders
✓ Locks class booking to paid members and class pack holders only

For solo PTs and growing fitness studios, billing software creates the recurring revenue base that sustains a serious fitness business.

The problems fitness business billing software solves

Manual workarounds that cost fitness businesses hours every week.

Tracking class credits manually across 50 members

Counting class credits on a whiteboard or in a spreadsheet is error-prone and creates disputes. Bizzly tracks every credit digitally and links it to the booking system.

Members booking classes when their membership has lapsed

Without automated access control, lapsed members still take class slots. Payment-gated booking means the class portal automatically refuses expired memberships.

Irregular income when PT clients pause or take holidays

Monthly membership billing charges regardless of whether the client trained that month. This creates a payment expectation that protects your income.

Manually chasing payment after every personal training session

Invoicing after each session, waiting for bank transfers, and reconciling payments against your schedule takes time that belongs in the gym.

How Bizzly works

From sign-up to your first paid booking in under 15 minutes.

Choose your industry Launch Pack

Pick the pre-configured template for your industry. Subscription plans, booking calendar, and Stripe payments are already set up, just add your services and rates.

Customer pays first, then books

A customer subscribes or buys a session pack. Stripe processes the payment. Bizzly creates their quota. They can now book sessions up to their limit.

Calendar enforces quota automatically

The booking calendar only shows slots to customers who have available quota. No double-bookings, no unpaid slots, no manual checking, the system handles it.

The Solution

How Bizzly handles fitness business billing software

Purpose-built features for fitness businesses — not bolted-on workarounds.

Monthly fitness memberships

Create tiers. Basic (group classes only), Premium (classes + 1 PT/month), Elite (unlimited classes + weekly PT). Stripe renews automatically. Members book against their included quota.

Recurring membership billing

Class pack billing

Sell class packs (5, 10, 20 classes) as one-off Stripe payments. Clients book classes against their pack balance. Credits have a configurable expiry period.

Prepaid class packs

PT session pack billing

Sell personal training in blocks (e.g. 6 sessions for £360). Clients pay upfront and schedule sessions at their own pace within the programme window.

PT programme billing

Payment-gated class booking

The class booking portal only allows booking for clients who have an active membership or remaining class credits. No active payment = no booking.
