The ease of use makes it very user friendly as well! I love how easy this application was to set up with my business partner at first glance we were able figure out what each other needed in order install properly into our accounting software (Quickbooks). There are some minor bugs but nothing too serious either way just keep using until they get fixed :) We have been working together since March 2016 so far no issues yet which has made us both feel comfortable enought o continue learning more about QuickBooks & Beebill's Invoice app!! Our goal now from here forward will be creating new billers/clients through quickbook integration along side bee bills api call. This helps me stay organized because when clients pay their monthly payment i can pull right off qb instead going back thru all old emails manually searching by email subject line etc.. It also allows them access directly within QB if.
