Commercial Refrigeration & Preventative Mechanical HVAC Maintenance
Deliverable Scope Management
Commercial mechanical contracts detail rooftop HVAC unit servicing, refrigerant recovery and charging, condenser coil chemical flushing, fan motor bearing lubrication, and thermostat controller calibration. When operating in Switzerland, clarify statutory deliverable milestones and MWST obligations upfront.
Billing Structure & Fee Models
Charge hourly certified technician rates plus emergency callout surcharges and wholesale material markups (typically 20%). Standard commercial settlement in Switzerland operates under Net 30 terms with statutory late compensation governed by 5% default interest rate under Article 104 of the Swiss Code of Obligations.
Protective Legal Clauses & IP Rights
Specify EPA or environmental authority refrigerant handling protocols, limit liability for pre-existing system fatigue, and mandate payment within 14 days. Under Switzerland commercial law, contracts should clearly define tax point dates and liability caps.
Allowable Business Expenses & Tax Write-Offs
Deduct digital manifold pressure gauges, vacuum pumps, refrigerant recovery cylinders, safety fall-arrest harnesses, and trade license renewals. Maintain all itemized purchase receipts for at least 10 years to satisfy Eidgenössische Steuerverwaltung audit mandates.
Timesheet & Milestone Logging Protocol
Archive refrigerant recovery logbooks, pressure test manometer charts, filter replacement compliance tags, and client technician sign-offs. For registered tradespeople in Switzerland, digital PDF records are classified as YES for accounting source verification.
Invoicing Tips & Best Practices for Tradespeople
Upfront Deposits & Retainers: Mandate upfront payment of all wholesale material costs prior to ordering components. Labor is payable immediately upon job completion via card or electronic transfer.
Common Invoicing Pitfalls:
- Failing to charge a dedicated diagnostic call-out fee when customers decline further repair work.
- Not obtaining customer signature on a job sheet acknowledging pre-existing property wear before commencing work.
- Lumping labor and wholesale components into one vague total instead of itemizing parts.
- Neglecting to record statutory compliance certificate numbers on the invoice.
Cross-Border Considerations: Trade services are physically anchored to fixed real property and are taxed exclusively according to the local tax jurisdiction of the job site.
Switzerland Tax Administration & Retention Rules
Registration Ceiling & Small Business Exemption: Mandatory MWST registration applies if annual worldwide taxable turnover exceeds CHF 100,000 (CHF 250,000 for non-profit sports/cultural associations).. Independent operators below this volume are not mandated to levy tax but must issue sequential receipts.
Invoice Serial Code Architecture: Must incorporate an unmistakable sequential transaction number uniquely identifying the billing record.
Standard Commercial Credit: Invoices default to 30 days settlement terms. Legally enforceable late fee rate: 5% default interest rate under Article 104 of the Swiss Code of Obligations.
Archival Retention Period: Keep all primary source documents, timesheets, and accounting registers intact for 10 years.
Structured E-Invoicing Transition: National administrative status is recorded as optional. PDF documents are accepted for independent contractors: yes.
