I had slowly been features adding to the Google Sheet template over the past year for my own use cases. At this point, the template allowed you to easily add metadata for your project, set billing rates and markup by task, and easily break out tasks into sub tasks and even sub sub tasks.
After working with the template over the past year or so, I thought others might find it really useful. It has saved me a ton of time when bidding on projects, made my estimates more accurate, and has even served as a deliverable that I could share directly with a client.
I was pretty happy with the current state of the template but knew it needed to sprucing up and some documentation. Accordingly, the majority of the work needed to get the MVP completed focused on styling and writing a clear read me. It took about a day to get the MVP completed.
