Invoicing Software for Personal Trainers & Fitness Coaches

In the US, the Bureau of Labor Statistics' Occupational Outlook Handbook (page last modified August 27, 2026) says "Fitness trainers and instructors lead, instruct, and motivate individuals or groups in exercise activities." It adds: "Many work variable or part-time schedules that may include nights, weekends, or holidays."

For a trainer, that work turns into a few kinds of charges: single sessions, session packs, monthly coaching, group classes, and extras such as a program write-up. Your client agreement sets what a pack includes, how long it lasts and any cancellation terms, and sales tax on services depends on your state, so ask your accountant or a lawyer before you set your terms.

For the sessions and packs you sell again and again, Billed's help center says "You can use these items and services to bill your clients."

For monthly coaching, Billed's invoice software page says "For clients you bill on a schedule, set up a recurring profile once." and you can "Choose the billing frequency (daily, weekly, monthly or yearly)".

Between sessions, Billed's mobile app page says "Billed for iOS and Android syncs with the web dashboard in real time, so you can invoice the moment a job is done." It also says "Add line items, your logo, and tax, then send by email or share a link before you leave the site."

These are sample figures, and sales tax isn't included. A trainer sells a 10-session pack at $85.00 a session, billed as one line item: 10 × $85.00 = $850.00.

The client asks to pay in two parts, so the invoice gets two scheduled payments by percentage, each with its own due date: 50% when the pack is bought, $425.00, and 50% thirty days later, $425.00. $425.00 + $425.00 = $850.00, which matches the invoice total, as Billed's help center requires.

Billed's invoice software page says "Connect your Stripe account and every invoice you send gets a pay button, so clients can pay by card." and "Connect PayPal to add a PayPal option as well." It also says "When a client pays by check or cash, record it as an offline payment so all your income is in one place." and "After a client pays, you can send them a payment receipt." For installments, Billed's help center says "A payment schedule lets you add a payment plan to the invoices." It also says: "Choose a suitable option among percentage or flat amount." and "Fill out the payment amount and due date of each payment." And it says "However, the sum of all installments should be equal to the total balance of the invoice."

Billed's expenses page says "An expense in Billed records who you paid, when, how much and which category it belongs to, with the receipt attached to the same entry." Recording equipment, certification or gym rental costs that way keeps them in one place for your records.
