Frequently Asked Questions
What should I include in a consulting invoice?
A consulting invoice should include: your business name and contact info, client details, invoice number, date, description of services (hours x rate or project fee), payment terms, and total amount due.
What are standard payment terms for consultants?
Most consultants use Net 30 (payment due within 30 days). For new clients, consider Net 15 or requiring a 50% deposit upfront.
Should I charge hourly or project-based?
Hourly works best for ongoing advisory work. Project-based is better for defined deliverables. Many consultants use a hybrid: a project fee with hourly overage for scope changes.
Do I need to charge sales tax on consulting?
It depends on your state and the type of consulting. Some states exempt professional services, others don't. Consult a tax professional for your specific situation.
