First of all, the biggest difference is that the invoice can be used as the original voucher for the cost, expenses and income of an enterprise, while the receipt can only be used as the voucher for the current payment. To put it bluntly, invoices can be included in the cost as proof of reimbursement; The receipt can only prove the cash relationship and cannot be included in the cost. Therefore, from the consumer's point of view, if it is only to prove that a certain amount of money has been paid, it is not used for reimbursement, then a receipt will do. However, if it is an expenditure for enterprise use, it needs to be used for enterprise reimbursement later. At this time, you must ask for an invoice.
There are also many kinds of receipts. It is used for internal business of the company, such as internal material transfer, employee deposit collection, return of excess business loan, etc. At this time, the proof that it is legal to use the internal self-made receipt can be recorded as cost. In case of business dealings between enterprises and the army, the receipts produced by the army can be used for tax exemption according to regulations, and such receipts can also be accounted for. Administrative fees incurred by administrative institutions can be recorded in the accounts using the receipts supervised by the financial department. There are also receipts produced by tax authorities for business dealings between enterprises.
