Consulting Invoice Essentials
Consulting invoices need detailed time breakdowns, expense reimbursements, and clear project phases. Include hours worked, hourly rate, project milestones, and any travel or research costs.
What to Include
- Time breakdown: Hours by task or project phase
- Hourly rate: $100-500/hour depending on expertise
- Project milestones: Discovery, strategy, implementation phases
- Expenses: Travel, software, research materials
- Retainer balance: Hours used vs hours remaining
Consulting Pricing
Junior consultant: $75-150/hour
Mid-level: $150-300/hour
Senior/specialty: $300-500+/hour
Project-based: $5,000-50,000+ depending on scope
Retainer vs Project Billing
Retainers provide predictable monthly income ("20 hours/month at $200/hr = $4,000/month"). Project-based pricing works for defined deliverables. Many consultants use both: retainer for ongoing advisory, project fees for implementation work.
