Executive Ghostwriting & Thought Leadership Opinion Editorial Standards
Deliverable Scope Management
Executive ghostwriting encompasses deep-dive subject matter interviews, personal memoir chapters, Forbes or trade publication op-eds, LinkedIn thought-leadership essays, and executive keynote speech drafts. When operating in Belgium, clarify statutory deliverable milestones and TVA obligations upfront.
Billing Structure & Fee Models
Bill per publication article or monthly thought-leadership retainer, requiring 50% advance payment before transcript synthesis. Standard commercial settlement in Belgium operates under Net 30 terms with statutory late compensation governed by Statutory commercial late payment rate under Law of 2 August 2002 (ECB reference rate + 8 percentage points).
Protective Legal Clauses & IP Rights
Incorporate complete ghostwriter anonymity agreements, moral rights waivers where legally permissible, and full copyright assignment upon final invoice payment. Under Belgium commercial law, contracts should clearly define tax point dates and liability caps.
Allowable Business Expenses & Tax Write-Offs
Deduct transcription AI tools, digital business publication subscriptions, executive interview recording hardware, and professional ghostwriter guild memberships. Maintain all itemized purchase receipts for at least 7 years to satisfy Service Public Fédéral Finances audit mandates.
Timesheet & Milestone Logging Protocol
Maintain interview recording audio archives, transcript text alignments, executive draft approval sign-offs, and publication date tear sheets. For registered writers in Belgium, digital PDF records are classified as CONDITIONAL for accounting source verification.
Invoicing Tips & Best Practices for Writers
Upfront Deposits & Retainers: Require a 50% deposit before drafting begins. For enterprise corporate whitepapers, bill 40% upfront, 30% upon draft submission, and 30% upon final sign-off.
Common Invoicing Pitfalls:
- Not specifying the number of revision rounds included in the flat article rate.
- Failing to clarify whether byline attribution (ghostwritten vs. bylined author) carries a pricing differential.
- Beginning research before the client approves a formal content brief or outline.
- Omitting provisions regarding AI generative tools or warranty of human authorship.
Cross-Border Considerations: Copywriting and content writing exported to foreign clients are generally exempt from domestic sales taxes under export service provisions.

Payment Terms & Late Penalties: National commercial law safeguards receivables. Typical credit windows span 30 days. Statutory compensation rate: Statutory commercial late payment rate under Law of 2 August 2002 (ECB reference rate + 8 percentage points).
Record Archive Period: Maintain complete accounting records and supporting documents for a statutory minimum of 7 years.
