I can't believe that I am defending them but I can't help myself.
Like anything in business, you need to weigh up the pros and cons. The devil is in the small print but then it always has been. I have had clients that used Rentsmart and knew exactly what they were getting into and why. If I had been able to offer them the kit on HP they would have bought from me.
Schemes like Rentsmart allow you to free up capital for other things. You get the use of a computer for less money than it would cost to buy it and all of the money you pay out to Rentsmart each year can be offset against profit in that year.
If you bought the computer outright, this would not be the case. You would have to treat the computer as an asset and depreciate it over several years. Depending upon how you did this you would get a capital allowance to offset against profit each year. The maximum you would be allowed in year 1 would be 40% of the cost of the computer.
Of course in the long run it will cost you more than if you bought it outright. Rentsmart are in business to make money and the small businesses that need to hang onto meagre capital are precisely who they target.
