We just launched AXSAR Solo - an all-in-one SaaS solution for Solo Founders and Small Teams.
It allows you to easily manage accounts/contacts, deals, help desk tickets, projects, tasks, invoices, proposals, time sheets, notes, todo lists, files, and diagrams, all in a single seamless SaaS solution.
