As already mentioned, we’re working on how to make Summary budget periods more flexible. Here’s a sneak peek 
You’ll be able to choose your preferred frequency and then select either a specific date (if you’re paid on a fixed date) or a specific day (ex. last Friday of the month).
Summary will also automatically adjust to day before or after if your date doesn’t fall on a business day.
This is still WIP, but would love to get some feedback!
