WordPress Invoice Pro is a quoting & invoicing plugin for keeping track of client. Create unlimited invoices and send each invoice via email to a client and view the invoices on your website domain, just like a regular post or page.
With encoded permalinks, the invoice with be super secure and harder to find publicly (this option can be turned on or off via the settings).
Example: youdomain.com/invoice/9id9i2jf9i23k0fgj107kf
I would also suggest setting the quote/invoice as “password protected” to enhance the security in case the quote or invoice has sensitive material. Note: The password is emailed to the client when you click “email client” (if a password has been set) so they can access it.
