I like that Dash has made it easy to integrate with other platforms such as Paypal for payment processing in addition of having their own platform which is very user friendly! It's also relatively cheap compared to competitors so there isn't much downside here either (although you do pay more than some others). The only thing i dislike about dash are all these different ways they have created where people can send out invoices or purchase orders but not necessarily from one system - confusing at times especially when dealing with multiple vendors who may use another invoice/purchase order software etc.. However this could be solved by integrating into an ERP instead perhaps? We were looking specifically for something simple yet robust enought handle our needs without being overkill / too expensive & we found what dashboard had provided us exactly how we wanted things done plus integration options within several systems was great!!
