E-Commerce Store Administration & Online Marketplace Operations
Deliverable Scope Management
E-commerce operational contracts outline product listing optimizations, SKU inventory updates, customer return RMA processing, supplier reorder communication, and customer review response management. When operating in Switzerland, clarify statutory deliverable milestones and MWST obligations upfront.
Billing Structure & Fee Models
Invoice monthly advance retainers for dedicated operational hours, or per-SKU catalog listing package rates. 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
Disclaim liability for marketplace platform account policy strikes (Amazon/Shopify), require client approval for supplier purchase orders, and mandate 30-day notice to terminate. Under Switzerland commercial law, contracts should clearly define tax point dates and liability caps.
Allowable Business Expenses & Tax Write-Offs
Deduct e-commerce inventory management tools, product image background removal software, high-speed internet connections, and online retail training courses. Maintain all itemized purchase receipts for at least 10 years to satisfy Eidgenössische Steuerverwaltung audit mandates.
Timesheet & Milestone Logging Protocol
Archive weekly stock level update logs, supplier purchase order tracking sheets, customer RMA resolution records, and monthly marketplace health reports. For registered virtual assistants in Switzerland, digital PDF records are classified as YES for accounting source verification.
Invoicing Tips & Best Practices for Virtual Assistants
Upfront Deposits & Retainers: Require 100% advance payment for monthly recurring hour bundles or packages. Unused hours expire at the end of each billing cycle (no perpetual rollover) to preserve capacity planning.
Common Invoicing Pitfalls:
- Permitting unused monthly retainer hours to roll over indefinitely into future months.
- Failing to define explicit response times or standard working hours across differing client time zones.
- Not using password managers or secure credential vaults, creating confidentiality risks.
- Performing specialized legal or financial bookkeeping tasks without tailored liability limitations.
Cross-Border Considerations: Cross-border remote administrative and virtual assistant services supplied to business entities qualify for zero-rated export treatment or reverse-charge mechanisms in most tax jurisdictions.
Switzerland Tax Administration & Retention Rules
Revenue Threshold Limits: Mandatory MWST registration applies if annual worldwide taxable turnover exceeds CHF 100,000 (CHF 250,000 for non-profit sports/cultural associations).. Freelancers operating under this ceiling must monitor trailing gross sales to ensure timely registration.
Serial Invoice Identification: Must incorporate an unmistakable sequential transaction number uniquely identifying the billing record.
Payment Pacing: Commercial credit agreements standardly require settlement within 30 calendar days. Late interest compensation: 5% default interest rate under Article 104 of the Swiss Code of Obligations.
Statutory Archive Requirements: Official regulations demand archival storage of all commercial bills for at least 10 years.
E-Invoicing Implementation: The government regulatory status is optional. Standard PDF invoicing is validated: yes.
