There are many companies in the Castellum, so it’s important to issue your invoice to the correct company and include the correct reference details. If this information is missing or incorrect, you risk payment being delayed and having to issue a new invoice. Here you will find answers to the most common invoice questions from our suppliers.
Payment Terms
We apply 30-day payment terms. Any late payment interest is charged according to the Interest Act. The main rule is that we do not pay any invoicing fees unless there is a special agreement.
Reference Marking
All supplier invoices should be marked with a nine digit reference string in the “your reference” field. The reference number indicates which property the order pertains to as well as a code for who ordered the goods/service. The person at Castellum who orders a good/service must always provide a reference number. If you lack a reference, please contact the person who placed the order and ask for a reference number.
Example of how the reference marking looks:
