Dear Potential Vendor,

We here at ABC, Inc. realize that times are difficult.  That you are shaking every tree for any possible business opportunity.  Let us make a few points clear:

1. Yes, our terms our non-negotiable.
2. When we ask for X amount in liability insurance on your part, we mean it.  This is not a suggestion but an expectation of doing business.
3. Yes, we do follow the governmental safety and quality standards as put forth by said agencies.
4. Just because you went to school with the cousin of the sister-in-law of the CEO's estranged brother, will not automatically get you a coveted vendor slot.
5. We have a prohibitively strict gift policy - NO GIFTS.
6. Calling me everyday for 3 months will only make me annoyed.  
7. Sending multiple emails a day, makes you SPAM.
8. Sometimes, the answer is simply - NO.

Thank you for considering doing business with ABC, Inc.

Sincerely,

Admin Gal
