You can order by email, fax or letter and you can pay be credit card, cheque or bank transfer.（ The payment is not due for 30 days from the date of the invoice but we would send the goods to you straight away.）括號內的句子意思是什么？我有點不是很明白？或許需要點商業知識，謝謝了。

發票開出后30天內付款為有效,但是我方會立即發貨給你方.

（ The payment is not due for 30 days from the date of the invoice but we would send the goods to you straight away.）在付款單日期起30日內付款，我們會立即發貨給你。invoice 在這里應該是付款單的意思，而不應是發票。
