How to create a contractor invoice

Quick answerA contractor invoice should identify the customer, completed work, amounts due, payment terms and a unique invoice reference.

Use an invoice after work or a billing milestone is ready for payment. Describe what was delivered and make the amount due and payment expectations easy to find.

Invoice details contractors should include

Include the invoice number, service date or billing period, line items, taxes when applicable, total due and payment instructions. Keep estimates and invoices as separate records.

One estimate is free. Your whole workflow belongs in Clousit.
