You start by choosing your legal form: limited company, LLP, sole trader or partnership. The wizard then asks only for the matching details, such as the registered number and office for a company or the business address for a sole trader, and whether you trade under a different name, because the Companies Act 2006 requires both names to appear. Next come your contact email, a short description of your services and the date from which this version applies.
The VAT and professional questions decide whether your VAT number appears and whether a paragraph on your professional body and compulsory insurance is added. Then you choose how you charge; if pricing varies from job to job, leave the basis to each quotation and the terms keep all three regimes. The remaining screens cover the deposit, payment term, notice period, liability cap, ownership of the work, portfolio use, non-solicitation of staff and whether disputes go to mediation before court. The preview updates as you answer.
