Invoicing Tips & Best Practices for Personal Trainers
Upfront Deposits & Retainers: Always sell sessions as prepaid single payments or multi-session packages paid 100% upfront before reserving recurring gym floor times.
Common Invoicing Pitfalls:
- Allowing clients to train on credit or pay retroactively at month end.
- Lacking an enforceable 24-hour cancellation and session forfeit rule.
- Not including medical clearance (PAR-Q) and liability waiver requirements in onboarding paperwork.
- Failing to enforce expiration deadlines on multi-session packages.
Cross-Border Considerations: Online fitness coaching delivered to international clients may be classified as an electronically supplied service subject to remote destination VAT/GST rules.
