Once your project cost estimate has been finalized and approved by the Sandkasten team - meaning your project is in Phase 3 - you can start shopping for your project. However, there are a few things you need to consider.

If the value of goods is between €200 and €1000 net for products in the same sector (e.g. only wood or only electronics), three quotations must be obtained before the ordering process. For example, three screenshots of different shopping baskets are sufficient. You have thereby demonstrated “market knowledge”. Please send the proofs to the Sandkasten team before ordering.

For goods with a net value of more than €1000, a call for tenders or a “direct award” must take place. This means that three formal inquiries must be submitted to three different suppliers. The Sandkasten team will be happy to take care of the tendering process for you.

Always try to purchase on account. You can also have the costs laid out and reimbursed by the university. However, this may take a few weeks. If you have expenses in cash, we need the receipt. For expenses that were not paid in cash (EC card, Paypal, credit card), we need a corresponding debit slip (bank statement). The above points must also be taken into account here. Purchases made via Amazon cannot be refunded.

When purchasing on account, please always use the following billing address:

Technische Universität Braunschweig
Transferservice
Bereich Wissenstransfer
Sandkasten
Bültenweg 17
38106 Braunschweig

Correct invoices
If you pay for services provided by musicians, artists or other sole traders, make sure your invoices or receipts are correct. Without certain details, they 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”.

If you need materials from the hardware store, you can pick up a purchase permit from the Sandkasten office (Bültenweg 17). You can then use this to buy from Bauhaus on account. The invoice will be sent directly to us and paid. The same applies to Luhmann Holzhandel GmbH and Ohlendorf.

Wenn außerhalb des Finanzplans noch Anschaffungen anfallen, sprecht diese unbedingt vorher mit dem Coach eures Projekts ab.

Note:
There are some things that cannot be financed by university funds:

• Food
• Beverages
• Everything without a correct invoice or receipt
• Orders outside the EU (without a German VAT number)
• Orders placed with Amazon

In certain cases, food and drinks can also be charged for sponsorships that run via the Braunschweigischer Hochschulbund. Please coordinate this with the Hochschulbund in advance – Contact the BHB.

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.
