the manner in which a sale is concluded depends on the style of the decision-maker - watch out for the signs: no-nonsense high-achievers are likely to decide very quickly and may be a little irritated if you leave matters hanging after they've indicated they're happy; cautious technical people will want every detail covered and may need time to think, so don't push them, but do stay in touch and make sure they have all the information they need; very friendly types may actually say yes before they're ready, in which case you need to ensure that everything is suitably covered so nothing can rebound later
