FAQ

How do consultants invoice clients?

Consultants typically bill hourly, daily, or per fixed milestone. Include a clear description of services rendered, dates, rates, and any expenses on every invoice.

Should I bill expenses separately?

Yes — itemize every reimbursable expense with a description and receipt reference. Mark non-billable costs clearly so clients understand exactly what they are paying for.

What payment terms should I use?

Net-15 or Net-30 are standard. New clients or large engagements benefit from a 50% upfront deposit or milestone-based billing tied to deliverable acceptance.
