Corrective Exercise & Posture Rehabilitation Coaching
Deliverable Scope Management
Corrective movement sessions address musculoskeletal imbalances, joint mobility restrictions, spinal postural alignment, and functional rehabilitation exercises designed in consultation with medical physical therapists. When operating in Denmark, clarify statutory deliverable milestones and Moms obligations upfront.

Bill through specialized evaluation consultations combined with 8-week corrective movement packages, requiring full prepayment prior to biometric diagnostic delivery. Standard commercial settlement in Denmark operates under Net 30 terms with statutory late compensation governed by Danish Lending Rate (Nationalbankens udlånsrente) plus 8 percentage points under the Danish Interest Act (Renteloven).
Protective Legal Clauses & IP Rights
Require physician medical clearance forms for rehabilitation clients, explicit non-medical disclaimer stating trainer does not diagnose pathological conditions, and 24-hour cancellation rules. Under Denmark commercial law, contracts should clearly define tax point dates and liability caps.
Allowable Business Expenses & Tax Write-Offs
Claim posture assessment grids, goniometers, specialized myofascial release tools, orthopedic continuing education seminars, and specialized clinical liability coverage. Maintain all itemized purchase receipts for at least 5 years to satisfy Skattestyrelsen audit mandates.
Timesheet & Milestone Logging Protocol
Maintain functional movement screen scoring sheets, joint mobility progress measurements, client referral notes, and session attendance tracking logs. For registered personal trainers in Denmark, digital PDF records are classified as YES for accounting source verification.
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.
Denmark Tax Administration & Retention Rules
Revenue Threshold Limits: Mandatory moms registration applies if turnover from taxable supplies exceeds DKK 50,000 within any 12-month period.. Freelancers operating under this ceiling must monitor trailing gross sales to ensure timely registration.
Serial Invoice Identification: Must utilize a continuous serial numbering sequence (fortløbende nummer) based on one or more distinct series.
Payment Pacing: Commercial credit agreements standardly require settlement within 30 calendar days. Late interest compensation: Danish Lending Rate (Nationalbankens udlånsrente) plus 8 percentage points under the Danish Interest Act (Renteloven).
Statutory Archive Requirements: Official regulations demand archival storage of all commercial bills for at least 5 years.
E-Invoicing Implementation: The government regulatory status is optional. Standard PDF invoicing is validated: yes.
