For any type of business to succeed, you have to get paid. So whether you do one freelance gig a month or run a full-time writing business, you need to calculate the time you've worked and bill your clients for it. That means you need to know how to write an invoice.
A breakdown of services: If you're manually creating the invoice using Microsoft Word or Google Drive Templates for invoices, you'll need to include a breakdown of the services rendered and any additional charges associated with your work. Make sure to include a column for each of the following: description of work or services, date worked, quantity, rate, hours worked and subtotal. This makes it easy to tally up the total when you list out multiple projects or tasks you've completed for the client.
