I’ve used Dubsado for my business since 2019 and it seamlessly helps me build and send proposals, contracts, and invoices all with a single email. It also has complex workflows, task lists, time tracking, calendar invites, and newly a mobile app. Take a look here: https://www.dubsado.com/?c=juststart

I used Dubsado but hated how clunky it always was! Although it did help me initially systemize my processes but the clunkyness and the lack of project management as well as missing some granular CRM features I got tired of it. I tried a few, but have been using withmoxie.com for a few months now! ITS AMAZING! SO MUCH BETTER THAN DUBSADO! And an even greater support team! Absolute fan!
