Magento

Hello,

When i buy new product from shop. Then I get an e-mail that “we” have got your order. Then I’ll open that order from Sales->Orders and Click Invoice and add that the invoice is send to customer I’ll get an error, that invoice is not created! It doesen’t send any e-mail to customer but creates invoice. I haven’t configured any e-mail addresses, but why i get it when new order is made, but i can’t send the invoice to customer.

How to automate the process of sending invoices to customer e-mail. I want them to manually send me money(to given account number in e-mail invoice).

Thanks in advance,
Azuu
