We won a sale recently against the Director of a competitor who claimed to have been a priest in order to impress the prospect. There was no mistaking the claim made during the pitch. He was never a priest. his credibility was shot.
Any small business owner buying POS or other software for their business should ask for all claims to be proven. Honest representatives will gladly arrange this. Dishonest representatives will present you with all sorts of excuses.
Most business owners have inbuilt BS meters which detect lies like the priest claim. Unfortunately, some do not and these folk can end up with a bad decision.
Software should be bought because it is proven to be right for the job and not because of wild claims.
