An invoice is a specification of, and request for, payment for services rendered. Invoices are simple to complete, but just like contracts, they need to communicate expectations clearly and concisely. In the case of invoices, the following information is required:
- Contact information for both parties.
- An invoice number, if you expect to do repeat business with the client.
- Specification of the work completed.
- Statement of due date for payment.
- Means by which payment will be accepted (usually credit or cash)
- Clarification if this is a partial payment for ongoing work.
