Invoice & estimate app for personal trainers
The invoice app for personal trainers
Personal trainers sell time in packages — ten sessions, a month of coaching, a program. Invoiceflint lets you invoice those packages from your phone between clients, send them by WhatsApp or email, and see who's opened them.

How Invoiceflint helps personal trainers
Built for invoicing on the job, not at a desk.
Saved packages
Save your 5-, 10-, and 20-session packages with prices, and invoice a renewal in a few taps.
Invoice by WhatsApp or email
Send the invoice link wherever you already message clients. They open it in the browser — no app or account needed.
See when clients open it
Get a notification when the client views the invoice, so you know before the next session whether it's been seen.
No money talk mid-workout
Scheduled email reminders follow up on renewals and unpaid invoices for you.
Billing tips for personal trainers
Invoice packages before the first session
Payment up front means commitment up front. Clients who've paid for ten sessions are far more likely to show up for all ten.
Put an expiry date on packages
Unused sessions can hang over you for months. A validity period on the invoice — say 12 weeks — keeps schedules moving and avoids awkward conversations.
Charge for travel to clients
Training clients at home or in a park means time on the road. Add a travel line, or build it into a higher in-home rate and say so on the invoice.
Invoicing questions from personal trainers
What should a personal training invoice include?
A personal training invoice should include your business name and contact details, the client's name, the sessions or package being billed, the price and any discount, how long the package is valid, your cancellation policy, the total, a due date, and how to pay.
Should personal trainers invoice before or after sessions?
For packages, invoice before the first session so the client is committed. For pay-as-you-go clients, many trainers invoice weekly or monthly for the sessions attended.
Can I give a discount on a training package?
Yes. Add a discount to the invoice so the client can see the saving next to the full price — a good way to reward renewals and referrals.
Does Invoiceflint work for online coaching?
Yes. Bill programs, monthly coaching, or check-ins the same way as in-person sessions, and send the invoice to clients anywhere by email or WhatsApp.
