What to include on a Management Consultant invoice
Your invoice needs the project name or engagement number because consultants usually have multiple projects running with the same client. Their accounts payable department will reject invoices they can't match to a purchase order or contract. Include the specific deliverable or phase you're billing for, your hourly rate or day rate if applicable, and actual hours or days worked. Many clients require you to break down expenses separately, especially travel costs, because they have different approval processes for fees versus reimbursements.
Most consulting agreements call for monthly billing in arrears, though you can often negotiate a retainer for the first month. Larger projects get milestone payments tied to deliverables like completing discovery or delivering the final report. Standard payment terms are Net 30, but you'll wait 45 to 60 days with big companies no matter what your invoice says. Government clients are even slower.
Send your invoice the day after month-end or right when you complete a milestone. Waiting even a few days puts you into the next payment cycle. Also, keep a timesheet as you go, not at month-end. Clients will question your hours if you can't explain what you did on specific days.
Frequently asked questions
How do management consultants set fees?
Independent consultants charge $150–$500/hour, daily rates of $1,500–$5,000, or project-based fees. Monthly retainers for ongoing advisory range from $2,000–$15,000. Value-based pricing is also common.
What should a consulting invoice include?
Include project name, engagement scope, hours by activity (research, analysis, workshops, presentations), deliverables completed, travel expenses, and any third-party costs.
Should consultants charge for travel expenses?
Yes. Flights, hotels, meals, and ground transport are standard reimbursable expenses. Bill at cost with receipts. Many consultants also bill travel time at 50% of their hourly rate.
