How do I write a letter on a company's letterhead?

1) Open Accounts → Company Letters (/accounts/letters), Compose. 2) Pick the company — its branding loads into the letterhead and preview. 3) Describe the letter for the AI assistant and press Write letter, or type the body yourself (a prompt on an existing body revises it). 4) Adjust the letterhead details for this letter if needed — name, tagline, header address, footer phone, page size (A4 unless you choose A3 or A2). 5) Check the preview, paginated as it prints. 6) Save, Download PDF, or Send for signature (it opens as a Saral Sign draft to place signers and fields).
