Do not be afraid of presenting a "contract" to your client.
Let me repeat, do not be afraid of presenting a "contract" to your client.
I know, I know, it seems so much friendlier and less formal to continue without a contract. And my goodness, you wouldn't want to do anything to rock the boat. Right? Wrong. There's no stability in the boat without a contract.
Consider this example. You need to get some repair work done on your roof, so you call a couple of different contractors out to your home. The first contractor gives you a written proposal/contract for the work, and sets the price at $2975. A second contractor comes along and says, yep I can get do the job for $2500. Everything about the second guy seems novice, he doesn't write up a contract, he just hands the number to you on the back of his business card. The first guy looks incredibly more legitimate at this point. In truth, the second guy might even be a better roofer. But who would trust his unprofessional approach? I think most people, myself included, would feel more confident with the contractor who gave you a written proposal, even though his price was higher. (Notice too that the first man's price wasn't a round number like the second guy; exact pricing is more valid in the eyes of the customer)
Plus, and this is a BIG plus; if you ever want to sell your business one day, which business is more sell-able? A business owner who has a list of customers that he services whenever they call? Or a business owner who has a nice stack of signed contracts?
So don't make the mistake of avoiding a contract. In fact, the comment that your customer made to you indicates there could possibly be a small degree of doubt in the back of his mind as to your companies approach...
"if i thought something wasn't right about you i wouldn't use you." That almost sounds like he's trying to convince himself that you're OK. It's important that you try to remove every shred of a question mark from the client's mind. You need to be seen as the consummate PROFESSIONAL who will make all their problems go away.
I am going to give you a gift. In fact I'm going to give it to everyone here. Here is a generic version of a contract that we have used for our carpet cleaning business. You will just need to update the highlighted areas of the contract with your data when you fill it out for your client. And for the sake of legality, you may wish to have your own attorney give it a quick review to see that it's legal in your state and for the scope of work you're intending. I hope it is helpful to you...
