sending invoice

sending invoice
never done it before.
i have a paypal account so is this better to send from paypal?
will people who dont have paypal will be able to pay?
if i want someone else to creat invoice and send but still i dont want him to log in to my paypal account, is it possible?

if you have more tips i will love to read
thanks

You can send an invoice from paypal. People without a paypal account can still pay with a credit card. You can't send an invoice through paypal without logging in from the account.

still
any other way to let other person to send invoice without logging to my paypal site?
