Create a Supplier Onboarding Checklist and Welcome Email

I need two documents to onboard a new supplier for my business. Here is my business context:

- Business type: [e.g., independent restaurant / retail boutique / residential construction contractor]
- What I buy from suppliers: [e.g., fresh produce and dry goods / women's apparel / lumber and hardware]
- Team size: [e.g., 4 people — me plus three staff]
- How I place orders: [e.g., by email every Monday / through a web portal / by phone]
- Payment terms I offer: [e.g., net-30 by check / payment on delivery / ACH within 15 days of invoice]
- Any compliance requirements: [e.g., all food suppliers must provide current food handler certification / all contractors must carry $1M general liability]
- Main contact on my end for suppliers: [e.g., me (owner) for new relationships, my office manager Sarah for ongoing orders and invoices]

Document 1: A supplier onboarding checklist for internal use — everything my team needs to collect and confirm before a new supplier is activated. Format as a checklist with checkboxes and brief notes on what each item means.

Document 2: A supplier welcome email — professional, clear, and specific. It should tell the supplier exactly how to work with us: payment terms, how to submit invoices, how we place orders, who to contact, and what our quality and return expectations are. Tone should be professional and direct, not overly formal.

Make both documents specific to the business context I've provided, not generic.
