It doesn't take much time if we use right tools. I've found Asana really good for task management with your team. As software dev, all you have to do is to tick completed tasks or write short comment if you are missing deadline for an individual tasks. Also, committing code multiple times a day with meaningful comments also helps.
Any advice for easily communicating with non-technical clients who wouldn't use technical tools?
I have faced many non-technical clients in past and trust me it's not easy. The best thing I could do is to double (sometimes triple) the original estimated timelines.
Make separate milestones for QA and UAT rounds.
Breaking the project in very small but presentable milestones helps in keeping non-technical clients updated and happy.
