Executive Calendar Management & Inbox Optimization Standards
Deliverable Scope Management
Administrative support contracts define dedicated diary schedule management, inbox triage protocols, meeting briefing preparation, international travel booking, and customer correspondence drafting. When operating in Australia, clarify statutory deliverable milestones and GST obligations upfront.
Billing Structure & Fee Models
Bill monthly advance retainers for dedicated hour packages (e.g. 20, 40 hours monthly), with unallocated hours expiring at the close of each 30-day billing period. Standard commercial settlement in Australia operates under Net 30 terms.
Protective Legal Clauses & IP Rights
Stipulate client responsibility for credential security via password managers, define standard operating business hours, and disclaim liability for third-party travel booking cancellations. Under Australia commercial law, contracts should clearly define tax point dates and liability caps.
Allowable Business Expenses & Tax Write-Offs
Deduct password vault enterprise subscriptions (1Password), dual-monitor home office equipment, noise-canceling headsets, and secure VPN service fees. Maintain all itemized purchase receipts for at least 5 years to satisfy Australian Taxation Office (ATO) audit mandates.
Timesheet & Milestone Logging Protocol
Log weekly hours tracked via automated software, completed task tick-sheets, travel itinerary confirmations, and monthly client review notes. For registered virtual assistants in Australia, 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.
Australia Tax Administration & Retention Rules
Tax Thresholds: Annual gross business turnover reaches or exceeds AUD $75,000 ($150,000 for non-profit organizations).. If annual revenues fall below this threshold, mandatory tax charging may not apply, though meticulous sales ledgers remain obligatory.
Sequential Numbering: Unique reference number identifying the document. For taxable supplies of $1,000 or more, buyer identity or ABN is legally mandatory.
Statutory Late Interest: Commercial agreements provide payment protection. Standard terms default to Net 30.
Audit Retention: You are legally required to retain all commercial invoice archives for at least 5 years.
E-Invoicing Requirements: Current B2B e-invoicing status is optional. Digital PDF invoices are officially recognized: yes.
