When completing a travel form and/or any form of claims for NSU, it is important to distinguish between what is accepted as a proper receipt, and what is not.
Our accountants have provided the following definition of what is accepted as a receipt:
A receipt is a document that shows that a vendor has received means for a service or goods. Or even more simple you buy something and get a document that specifies this. In short, a receipt should state the date, the amount and what has been bought. If you look at Wikipedia they state the following:
A receipt (also known as a bill of parcel, unpacking note, packaging slip, (delivery) docket, shipping list, packing list, packing slip, delivery list, manifest or customer receipt), is a document acknowledging that a person has received money or property in payment following a sale or other transfer of goods or provision of a service. All receipt must have the date of purchase on them. If the recipient of the payment is legally required to collect sales tax or VAT from the customer, the amount would be added to the receipt and the collection would be deemed to have been on behalf of the relevant tax authority. In many countries, a retailer is required to include the sales tax or VAT in the displayed price of goods sold, from which the tax amount would be calculated at point of sale and remitted to the tax authorities in due course. Similarly, amounts may be deducted from amounts payable, as in the case of wage withholding taxes. On the other hand, tips or other gratuities given by a customer, for example in a restaurant, would not form part of the payment amount or appear on the receipt.
According to the NSU accountants, a receipt is issued after a purchase but an invoice is issued either before or after. You usually pay the rent beforehand but you pay electricity afterwards.
Credit card receipt is not a receipt that is approved by auditors since it doesn´t state what the purchase if for.
