Repeated invoicing: If you have already issued an invoice with the same information as the current invoice, you may be prompted with the same information as last time when invoicing again. At this point, you need to check whether the previous invoice has been successfully issued and sent to the customer. If it is not successfully issued or sent, it is necessary to reissue or modify the previous invoice information.
Customer has deducted: if the customer has deducted or reimbursed the previous invoice, the invoice with the same information may be the same as last time. At this point, you need to confirm whether the customer has deducted the previous invoice. If so, you need to handle it according to the customer's requirements.
System data synchronization problem: Sometimes, the electronic invoice system may have data synchronization problems, resulting in the newly developed invoice information being the same as before. At this point, you can try to wait for a period of time, waiting for the system to automatically update the data. If you can't solve the problem after waiting for a period of time, you can contact the electronic invoice service provider for consultation.
If you can't find the previously issued invoice information, you can try to query and retrieve it in the electronic invoice system. Under normal circumstances, the electronic invoice system will provide a variety of query methods, such as querying according to invoice number, invoice date, amount and other information. You can choose the corresponding query method according to the actual situation and enter the corresponding information to query. If you still can't find the corresponding invoice information, you can contact the electronic invoice service provider for consultation.
