Frequently Asked Questions

• How do consultants typically bill clients?

  Consultants use various models: hourly rates, daily rates, project-based fees, retainer agreements, or value-based pricing. Choose based on project type, client preference, and the value you provide.

• What's a retainer agreement and how do I invoice it?

  A retainer is a recurring fee for ongoing availability or a set amount of monthly work. Invoice retainers at the beginning of each period, then either include services within that retainer or invoice additional work separately.

• Should I itemize consulting hours on invoices?
  Yes, transparency builds trust. Include dates, tasks performed, time spent on each task, and your hourly rate. Even with project fees, consider showing time invested to demonstrate value.
• What payment terms work best for consulting?
  Many consultants use Net 15 or Net 30 for established clients, but require 50% upfront deposits for new clients or large projects. This protects cash flow while building client relationships.
• How do I invoice for consulting retainers?
  Invoice retainers at the start of each period (usually monthly). Clearly state the retainer amount, what it covers (e.g., "10 hours of consulting"), the billing period, and how additional hours will be billed.
