Very easy to register, handle payments with my bank account or card; can be installed in different countries so that it's not only available at home but also from abroad! There are still some bugs which need attention (for example when making an invoice I receive sometimes errors). But they have promised me several times already new updates will fix this issue soon as well as other issues such us invoicing via email etc.. If you want all your sales data centralized - use their app called SalesforceIQ!! It's free of charge if we pay $99 per month otherwise there would simply by no reason why anybody should ever chose any third party over our own platform since both offer exactly same functionality/capabilities regarding customer information storage & access.
