Help me fill in a big customer's supplier form.

Who it's for: [type of organisation]
The questions: [paste them]
What I already have: [e.g. insurance certificate, a health and safety statement]
My business: [size, what you do]

Ask me up to 3 short questions first if anything important is missing. Wait for my answers.

Then:
1. Each question in plain English and what they're really checking.
2. A list of documents to find or write, in the order I'll need them.
3. Short draft answers where I've given you the facts; leave a clear gap where I haven't.
4. Questions to ask their contact if something doesn't apply to a business my size.
5. A covering email when I send it back.

Use only what I've given you, leave blanks for any price or fact I haven't given, and don't invent anything. UK English. Don't invent facts or policies; flag anything I should check with an adviser. Remind me to confirm by phone, on a number I already have, that the form really came from them before I send bank details.
