Your receipt / invoice for your subscription will be emailed to you automatically every time you're billed. All your past receipts are also available in the billing history section of your account.
Please note that your receipt won’t be available until you are billed. If you are in a trial period of a Pro or Team plan then your invoice will be available at the end of your trial period, when the first payment is made.
To print or save any of your invoices, press CTRL+P (Windows) or CMD+P (Mac) to open the printing menu when you have your invoice on-screen.
