These documents give detailed technical specifications for our software filing service. Software filing allows users to send information to Companies House digitally.
You’ll need expertise in extensible markup language (XML) to develop software.
If you’re developing accounts software, you’ll also need expertise in inline extensible business reporting language (iXBRL).
If you’re developing more complex accounts packages, you’ll need to understand our zip functionality and how we use this in the Companies House software filing service.
If you’re a package accounts filer or developer, you must read and understand the file structure and the validation rules.
