Well i have to say i am generally not the type of user writing reviews about products.
So you may apologise to amount of my written reviews.
But i have to admit that after i was in need of some modification for QuickSell, the developer instantly gave me a hand and customised the product to fit my needs by 100%.
In general, QS works out of the box pretty well, but i needed some pdf-postprocessing so it required some modification.
I think QuickSell is a brilliant alternative for all those who try to sell documents and hate the bulky and complicated style of Docman.
I started with docman + docmanpaypal, but changed over to QuickSell, for the before mentioned reasons.
With Quicksell it takes 1-5 Minutes to install, 1-2 Minutes to add a new item, and 0 effort to sell items.
