Second, the characteristics of electronic invoices 1, the advantages of issuing electronic invoices will significantly save the cost of enterprises in the invoice, save the cost of printing invoices, and does not include the indirect cost of enterprise invoice management. And the electronic invoice system can be combined with the enterprise internal ERP, CRM, SCS and other systems, the invoice information comprehensive electronic and centralized processing, help the enterprise itself account processing, and can provide timely decision-making support to business operators. Electronic invoices are more convenient in storage, inquiry and access, and also facilitate e-commerce websites to provide consumers with more convenient services. And can reduce the paper invoice resource waste phenomenon, will reduce deforestation, more environmentally friendly, in line with the future development of mankind. The introduction of network invoices is the inevitable way to regulate e-commerce tax, which is conducive to the state regulation of network transactions, but also conducive to the maintenance of the legitimate rights and interests of consumers. 2, drawbacks of the popularization of electronic invoices, the implementation of the online shopping market has been relying on the price advantage of the existence of a serious test, many merchants will be imposed on the cost of electronic invoices to the consumer, and ultimately lead to the price of the product is high. Some regular e-commerce can issue paper invoices, such as Jingdong Mall, Dangdang, Tmall, etc., although the price of these products compared to the Taobao platform price is slightly higher, but to give consumers a sense of norms, but also more peace of mind. Taobao platform is to C2C (person to person) mode, because most of the C2C merchants are not registered in the business sector, so there are barriers to invoicing. But also because of this, the C2C way than the B2C way a large part of the tax cost, the price of the product is naturally cheaper. After the popularization of electronic invoices, C2C ordinary merchants will no longer be "spared", on the advantages of online shopping at low prices to bring a blow. This also makes everyone for the popularization of electronic invoices although supportive but hesitant, so after the government issued a few months before the merchants formally start to implement. Although the state has made it clear that the legal effect and basic use of electronic invoices are the same as paper invoices, and that electronic invoices can also be reimbursed into the accounts, the Beiqing Daily reporter found in an interview that many business financial personnel have a headache with electronic invoices. "As consumers print their own, so there will be differences in paper quality, printing effect, which is equivalent to the original invoice of the physical anti-counterfeiting properties are canceled, the responsibility for identifying the authenticity of all pushed to the financial staff, the responsibility is really too big!" Some corporate finance staff said they usually recommend that employees try to choose to open ordinary invoices of business consumption, but more and more businesses only provide electronic invoices, to reimburse these invoices tend to be in the staff and finance staff disagreements. In addition, the characteristics of electronic invoices can be repeatedly printed also make how to prevent repeated reimbursement of the problem faced by corporate finance staff. An enterprise's financial personnel have made a special test, the same electronic invoice after copying and the original invoice is almost exactly the same, if used to repeat the reimbursement, the financial staff simply can not identify. In this regard, most of the financial staff can only take the method of reimbursement of each electronic invoice number down, each time the reimbursement should be queried once the invoice has been reimbursed, which undoubtedly increased the pressure of work.
