The software itself should help me save time ... it's far from clear! Unfriendly, difficult to use, some functions such as export tariffs is impossible (accepts no Batiprix for example), when suppliers could not send me any rate base ... too lightweight for Software artisan conscious propose clear papers and the latest regulations. EBP quotes and invoicing of the building is somewhat transformable, so this is a product that does not respond to a particular request and the user has the feeling of having to adapt ... it's a little backwards right even. Regarding the seller asked him 3 times a bill and he did not even deign to answer me !!!
