What is a invoice generator for consultants, and what goes on one?
An invoice is a formal request for payment. You send it to your client after completing work or reaching a payment milestone. It contains your business details, a description of the services rendered, the total amount due, and payment instructions.
Key components
- Invoice number — a unique sequential reference for your records and the client's accounts payable.
- Due date — when payment is expected. Net-15 or Net-30 are common.
- Line items — individual services or products with quantity, rate, and total.
- Payment terms — how you accept payment (bank transfer, PayPal, etc.) and any late fee policies.

Frequently asked questions
A brief 15-minute fit call should be free. However, if the client wants a 60-minute deep dive to extract actionable advice, you should bill it as a "Strategy Session." You can offer to credit the cost of this session toward the main project if they hire you.
Travel, lodging, and per diem should be billed as reimbursable expenses on your invoice. Always attach the physical or digital receipts to the final invoice to maintain transparency.
