开发票英语怎么说

"开发票"在英语中翻译为"issue invoice"。

其中"issue"表示"发出"，"invoice"表示"发票"。

例句：

Can you issue an invoice for this purchase? (你能为这次购买开一张发票吗？)
We will issue an invoice after the goods are delivered. (在货物交付后我们将开具发票。)
They asked us to issue an invoice with a specific tax rate. (他们要求我们开一张具有特定税率的发票。)

这里"invoice"来源于中文"发票"，是取"发"和"票"的意思，进而转化为英文词汇。
