In the current climate, I would strongly encourage anyone buying or selling services to invest in practical negotiation training. Most businesses are under a huge amount of pressure to maintain revenue streams, and this means that there are huge opportunities to negotiate discounts if you have the right skills to do so.
"If you don't stand up to your clients when negotiating fees, they probably won't hire you"
Many routine negotiations are more about behavioural skills than negotiation theory – ignoring practical training in favour of “seminars” is unlikely to deliver a return on investment in either the short or long term.
