there is no necessary connection between return and invoice. No matter whether the merchant has issued an invoice or not, it can be returned for a refund, but it must meet the conditions of return. If the goods have problems or meet the conditions of unreasonable return, they can be dealt with through refund rights protection.

under normal circumstances, we find that the invoice was issued incorrectly in the current month, or the invoice needs to be returned and reopened for various reasons, so we can void the invoice directly in the invoicing system. Cross-month invoices cannot be voided in the system, only invoice red ink offset can be made. To put it simply, once you made a wrong invoice, now you need to make an invoice exactly like the blue one in red, so you can flush the original invoice and then make a correct invoice again.

Of course, there will be no scarlet letter on the invoice, so the amount issued by the red-ink invoice is negative. Invoices shall be issued in accordance with the prescribed time limit, sequence and columns, all of which shall be issued in one lump sum and stamped with special invoices.

No unit or individual may commit the following acts of falsely issuing invoices:

1. Issuing invoices for others and themselves that are inconsistent with the actual business conditions;

2. Let others issue invoices for themselves that are inconsistent with the actual business conditions;

3. Introduce others to issue invoices that are inconsistent with the actual business situation.

if you have issued an invoice after purchasing a commodity and now want to return it for a refund, then you need to return the invoice to the seller for invalidation, and then return it for a refund. If the invoice of the other party can't be voided, you need to buy this invoice, and you may need to make a deduction when you refund it.
