Invoice clients for AI strategy, LLM projects, and automation consulting. Professional invoices from Tidybill.
An AI consultant invoice covers work helping organisations understand, evaluate, and implement artificial intelligence technologies to improve business outcomes. AI consultants advise on AI strategy, identify use cases where AI can add value, assess technical feasibility, select appropriate tools and platforms, oversee or execute AI implementations, and help organisations build internal AI capabilities. Work ranges from high-level strategy engagements (AI readiness assessments, AI roadmap development) to hands-on technical work (building LLM-powered applications, implementing RAG systems, automating workflows with AI agents). The AI consulting market is rapidly evolving, making clear scoping and regular communication essential. Because AI implementations often depend on third-party API services (OpenAI, Anthropic, Google), passing through API costs as reimbursable expenses is standard practice.
| Service | Typical Rate | Unit |
|---|---|---|
| AI consulting (day rate) | 900 | day |
| AI strategy and roadmap development | 4000 | project |
| LLM implementation / RAG system build | 5000 | project |
| AI workflow automation | 2500 | project |
| AI readiness assessment | 2000 | project |
| AI training workshop (full-day) | 1500 | session |
For strategy engagements, invoice at the end of the engagement on delivery of the strategy document. For implementation work, invoice at milestones: prototype complete, initial deployment, production launch. For training workshops, invoice per session. Always pass through API costs at cost with the provider invoice attached. AI projects move quickly; keep clients informed of scope changes and issue change orders before any out-of-scope work.
