Consulting-Specific Considerations

Billing Structures

Consultants typically use one of these billing models:

  • Hourly billing — charge per hour worked, with detailed time entries
  • Daily rate — common for on-site consulting engagements
  • Fixed fee — a set price for a defined scope of work
  • Retainer — a monthly fee for ongoing advisory access
  • Value-based — pricing tied to the outcome or value delivered

Your invoice should clearly reflect which model you are using and provide enough detail for the client to verify the charges.

Expense Reimbursements

Many consulting engagements include reimbursable expenses such as travel, accommodations, meals, and specialized software. List these as separate line items with receipts available upon request.

Sample Line Items

| Description | Hours/Qty | Rate | Total | |---|---|---|---| | Strategic planning workshop facilitation | 8 hrs | $200 | $1,600 | | Market research and competitive analysis | 12 hrs | $200 | $2,400 | | Executive presentation preparation | 4 hrs | $200 | $800 | | Travel expenses (round-trip airfare) | 1 | $450 | $450 | | Hotel accommodation (2 nights) | 2 | $180 | $360 |

Best Practices for Consultants

  • Reference the engagement agreement or SOW number on every invoice
  • Separate consulting fees from reimbursable expenses
  • Include a summary of work completed during the billing period
  • Submit invoices on a regular schedule (weekly, bi-weekly, or monthly)
  • Keep detailed time records to support your billed hours
