Aldelo Express is an App developed by Aldelo that adds to the popular Aldelo Pro (a Windows-based version) by enabling better options like iPad-based hardware, intuitive designs and integration with AldeloPay. The software comes in two different models, the subscrition-based model, in which you pay a monthly subscription per user and a free model, where you process the credit cards with AldeoPay (or an approved Aldelo processor) and they give you the software for free. All you need to buy is you hardware.
