When the invoice is uploaded on the network, the digital tax certificate will be invalid during the process of adding digital signature to the electronic invoice, and the verification system of the tax bureau will also fail. These are caused by non-human factors, which are rare, but they are inevitable at present. Failed invoices must be voided and reissued, and cross-month invoices need to be reissued by the tax bureau stub.

Matters needing attention in the use of electronic signature

In fact, there are many forms of electronic signature, which can be set on the third-party platform. Electronic signature can also support handwritten annotation, which makes the handwriting delicate and true. The stronger the handwriting is, the thicker the handwriting is, and the handwriting data is bound to the document content to prevent illegal copying of electronic handwriting.

Electronic signature can also be used as graphic signature, but graphic signature has no legal effect. Graphic signature can be used for announcements and workflows in enterprises, providing seal making and management functions. Administrators can assign permissions to use signatures in the background and reset signatures. Users can set and manage the password of signature within their own authority, and can use drawing software to generate and import electronic signatures. Graphic signature can bring efficient office for enterprises and is suitable for small enterprises.
