i recently bought a round and i held back 500 retention, and i glad i did because the round he sold was supposed to have been worth 550 a month, but after me working it the gross value to me after the cancellations and messer which i eliminated straight away was worth 350, so in real terms he would have got 4.5 times instead of the agreed 3 times. he wasnt happy but after a meeting he conceded and reduced the cost . remember that a customer who liked it done trad before may be difficult to change to wfp .some people just dislike wfp . there is a lot of wc who dont do it properly. (inc me when i first started.) experience changes that
