Invoices accompany every Dropbox Pro upgrade and can be found within your Dropbox account settings online. We do not provide invoices prior to a subscription purchase taking place. If you've upgraded to a Dropbox Pro account, you can find your invoices and transaction history on the payments section of your account settings.
Your transaction history lists all records, payments, adjustments, and refunds. To see an invoice, look for the links next to the 
invoice icon. Click on the link for a printable invoice.
If you're the administrator or billing contact of a Dropbox for Business account, you can access your invoices and receipts on the Account page of the Admin Console. Look for the Billing history section.
