Invoices

Invoices must always include the billing address listed below, never your private address.

Billing address:
Technische Universität Braunschweig
Transferservice
Bereich Wissenstransfer, Sandkasten
Bültenweg 17
38106 Braunschweig

If you need material from the hardware store you can pick up a shopping permit from the Sandkasten office (Bültenweg 17) by arrangement with your project coach. You can then use this to make purchases from Bauhaus on account. The invoice will be sent directly to us and paid. The same applies to Luhmann Holzhandel GmbH.

If you pay for services provided by musicians, artists or other sole traders, make sure that the invoices or receipts are correct. Without certain details, these are not valid. Checklists for invoices over and under 250 euros can be found on the IHK Berlin website under “General mandatory information on invoices”.

Reimbursement of cash expenses

If you are unable to purchase something on account, it is possible for you to display the costs and have them reimbursed by the university. The following documents must be received by us no later than two weeks after the display.

In order to be able to reimburse your expenses, we need the completed “Antrag auf Auslagenerstattung” with the attachment from you. You will receive the document from your coach on request.

If you pay the expenses in cash, we need the receipt in addition to the application.

If you have paid the expenses by EC card, PayPal or credit card, we need the receipt and a corresponding debit receipt of the amount (bank statement), if available.

If you take the above points into account, there should be no problems with billing. If you are unsure about an order, a supplier or similar, it is better to ask too much than too little.
