where can i dowload my bills?
What do you mean by bills? A bill can be a dollar bill, or it can be some notice from someone you owe them money. So you need to explain what you are talking about please.
If you mean how can you get your money from fiverr, you sign up with Paypal and then supply fiverr with your email and Paypal information.
Maybe she means the invoices for the gigs bought by her.
