I am expereinced with many kinds of sales situations and know that HOW you deliver the message is often more important than what the message is.
As far as details go, the answer depends to a degree on what kind of product or service you are selling, at what price level (2 figures or 7?) and how (personal sales pitch, telephone, text).
Here are some general remarks first regarding pitches.
1) Address the customer's situation - whether his business or personal situation. Show him that you "get" him and can speak his language.
2) Convince him of your expertise - he needs to know that you know what you are talking about.
3) Show him: a) Why he should buy now, b) What's in it for him and c) Why you/your product is the best choice.
4) Show him what your commitment to him is.
5) Tell him how he should make a decision.
6) Stick to your guns - you have something of value and you are not willing to do everything and anything to make the sale.
If you are actually speaking to your prospect, there are a number of techniques you can apply to most situations.
1) Listen to him carefully and identify words he uses that have meaning to him so that you can...
2) Repeat these words back to him exactly, in the exact order if possible. This is called "Pacing".
3) Mirror his body language whenever you can - not immediately or exactly, but close enough. This is called "Mirroring"
With pacing and mirroring you give him the subconscious imperssion taht you "get" him and that you are alike.
4) Greet him with a genuine smile and smile whenever the situation allows. Smiles elicit smiles, and smiling causes a feeling of happiness.
5) Maintain good eye contact. Comfortable eye contact, but contact that is more frequent and is held longer than people normally do.
This communicates confidence, honesty and genuine interest in him.
6) When not mirroring, maintain open, relaxed body language.
NLP (neurolinguistic programming) offers other related techniques.
