A Capability Statement provides information about your business. It explains your Who, What, Where, Why, How, and When.
Every business should have a minimum of two statements. The first being a comprehensive document of about 15-20 pages. Every Tender submission or Expression of Interest should include this document.
It's an excellent idea to add photos of products or services as well as graphs or charts to show what you can do and how you do it.
The second document is a concise, summarised two-page document. This is ideal for the smaller customers and great to include as a PDF with any emailed quote.
