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.
