I know that they rule is to never book with a vendor who is not willing to give you a contract.
Our potential chair cover company and tranportation/shuttle provider both come highly recommended (and are on the "preferred" list) by our venue and the reviews I can find appear to be good. The prices are right but...urgh...they both don't work with a contract. I really can't believe that any reputable small business is willing to work without one. I'm really concerned about booking anything until there is accountability - in writing - for the services promised at this point in the planning. I tend to believe that people out there working on reputation and verbal marketing alone would not risk their livelihood but, c'mon, FI and I want contracts!
How would you go about addressing this with the vendors without giving the impression that you are a know-it-all trying to tell a person how to run their business??
We are about 8 months out from the wedding and I'm getting a ton of planning out of the way now. All the more reason for agreements in writing! There is time but I don't want to sit too long and risk having them both book up.
