Online shopping has issued an invoice and can be returned. As long as the purchased goods are within the validity period and problems are found, they can be returned regardless of whether an invoice is issued. In order to ensure the quality of products and protect the legitimate rights and interests of consumers, the regulations stipulate that if the goods sold by the sales company have problems during the warranty period, they can not only return them at any time, but also make multiple compensation.

Electronic invoice return is invalid. If it is returned after opening, the received invoice will definitely be unusable. When you return the electronic invoice, the seller will void the electronic invoice that has been sent to you. Even if you want to use it, the financial department will not agree. It's already a toll ticket. Once discovered by the tax bureau, it will be regarded as tax evasion.
