How do you write a letter to supply goods to an organisation?

Well, honey, first you gotta start with a proper heading with your contact info and the date. Then, get straight to the point in the body by stating what goods you're supplying, the quantity, and any terms and conditions. Wrap it up with a polite closing and your signature. And don't forget to proofread, we don't want any embarrassing typos now, do we?
