Either way, the invoice is letting you know the who, what, where, when, why and how of paying the consultant for their services.


If your business hires a marketing consultant to work on a specific campaign, for example, they might send you an invoice that charges by the word for their writing pieces-or, the invoice amount might be for an hourly rate or a lump sum for completing the entire scope of a project. Invoices are most commonly used when services or a large quantity of goods are sold. Once the agreed-upon product or service has been delivered, the company/seller (you, in this case) sends an invoice-usually as either a paper copy or in electronic form-to the customer/buyer as a way to let them know that it’s time to submit payment and how. The bottom line is, if you’re a small business owner, the purpose of an invoice is to make sure your company gets paid. Invoicing software can help improve the purchasing process.
