What is a CAS file?

A CAS file is a zip file which holds the information regarding the initial registration details of your newly formed company. Accounting practices often require a CAS file because they use BGL’s software to store corporate records. The CAS file will connect with BGL to add your newly formed company’s details to BGL.

There is an option to order a CAS file on our order forms. Note that Castle provides a CAS file as a courtesy to clients at no additional cost.
