What is a invoice generator for it 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
Emergency or weekend support should be billed at 1.5x or 2x your standard hourly rate. Add a line item for "Emergency Out-of-Hours Support" so the client understands the premium nature of the service.
If you buy servers or laptops for a client, you can invoice them for the hardware plus a procurement markup (10-15%). However, it is often safer for cash flow to have the client buy the hardware directly using their own credit card.
