Here are a few tools to simplify your life.
Marketing a book while the book is still getting self-published makes for a complicated project. This is especially true if the author is self-publishing for the first time. My book How to Self-publish and Market a Book address this situation by integrating the publishing and marketing tasks into a single unified project. Despite all the directions in the book, I felt the project need additional ways to control and manage it. For this purpose I constructed a spreadsheet that offers a way to just that. You can find more information about this tool at http://hankquense.org/wp/writers-and-authors-resource-center/guides-and-checklists/
But spreadsheets aren’t for everyone. That fact led me to develop another tool that will appeal to some. It’s a Kanban style project board template. It has every publishing and marketing task stacked into two separate columns. When you start a task, you can drag it into a “In progress” column and then into a “Completed: column when the task is finished. Thus you have a visual indication of the project’s progress. Kanban boards such as this can’t be inserted into a WordPress website. Consequently. I had to develop the tool on the Notion.so website. To use the board, you’ll have to get a Notion account, but that is free. Once you have the account, you can duplicate my template and paste it into your own Notion workspace. Here is a screen shot of the template:
