Invoicing Tips & Best Practices for Personal Trainers
Upfront Deposits & Retainers: Always sell athletic training sessions as prepaid single payments or multi-session packages paid 100% upfront before reserving recurring gym floor times. Enforce strict 90-day package expiration windows.
Common Invoicing Pitfalls:
- Allowing gym clients to train on credit or pay retroactively at month end.
- Lacking an enforceable 24-hour workout cancellation and gym session forfeit rule.
- Not obtaining signed physical activity readiness questionnaires (PAR-Q) and liability waivers before starting heavy compound lifts.
- Failing to enforce expiration deadlines on prepaid 10-session fitness packages.
Cross-Border Considerations: Online fitness coaching and nutritional programming delivered to international clients may be classified as an electronically supplied service subject to remote destination VAT/GST rules.
Norway Tax Administration & Retention Rules
Turnover & Registration: Mandatory registration threshold is NOK 50,000 turnover of goods and services subject to VAT over a 12-month period.. Operating under this fiscal cap permits exempt billing in eligible circumstances while requiring complete invoice ledgers.
Chronological Numbering: Must utilize pre-numbered sequential identification numbers (maskinelt tildelte nummer) from an orderly series.
Payment Terms & Late Penalties: National commercial law safeguards receivables. Typical credit windows span 14 days. Statutory compensation rate: Statutory default interest rate (forsinkelsesrente) determined semi-annually by the Ministry of Finance.
Record Archive Period: Maintain complete accounting records and supporting documents for a statutory minimum of 5 years.
