You are better of in the beginning, looking to a Restaurant Depot or Costco/Sams type place. Going direct to a distributor forces you into both volume and contract terms that are onerous for a beginning company. My friend with the coffee shop buys all of his sodas and waters from Jetro/Rest. Depot or Cash and Carry (like RD). I have other friends in the business who buy from Distributors, but, it gets to be a pain. They want you to do things their way.
Whip It Off, Chambers!
