有人会说，现在运营商提供的发票都是电子发票怎么办？
Some people will say that the invoices provided by operators are all electronic invoices.
如果运营商已经把电子发票打印出来，你看一下，如果四大要素都是清楚的，盖上贵司公章就可以用了。如果运营商没有帮着打印，我们的建议是让运营商把发票发到客户的电子邮箱中，然后在电子邮箱中下载打印出来盖上客户的公章。（这里不是说的运营商的）
If the operator has printed out the electronic invoice, you can see that if the four elements are clear, you can use your company's seal. If the operator does not help print, our suggestion is to let the operator invoice to the customer's e-mail, and then download the print in the e-mail to stamp the customer's official seal. (This is not about operators)
