Please send us the invoice with signature and seal in two copies, we will arrange the payment once we recieve the original paper. this is a requirement of our finacial department.
决对是人工翻译
注意:上面英文中表达的意思是寄将同一个发票寄两份过来
如果你两个发票是不同的发票的话,表达就不同 了,如下:
please send us the two pieces of invoice with signature and seal ,后面一样
"Should be need financial payment, please send us two copies of invoice to be signed and sealed, arrange payment immediately after we receive the original"
