Frequently Asked Questions
What should a consultant invoice include?
Include consultant details, client information, itemized services with hourly rates or project fees, deliverables, engagement dates, payment terms, and clear payment instructions.
How do I bill for retainer-based consulting?
List the total retainer fee on the invoice, then deduct hours or services rendered from the retainer, showing the remaining balance or the amount due.
Should consultants charge hourly or per project?
Both are common. Hourly rates work for ongoing advisory; project fees work for defined deliverables. Some consultants use hybrid models.
What payment terms should consultants use?
Net 15 or Net 30 are standard. Some consultants use Net 10 for large projects or require upfront payment for new clients.
How do I show scope and deliverables on an invoice?
List specific deliverables (e.g., 'Strategic Roadmap Report' or 'Implementation Plan') as line items to demonstrate the scope of work.
