1) Pre-launch: Finding the time while working to create your SaaS (prior to go launch).
2) Post-launch: Ensuring you have the time to support your customers, and resolve issues in a timely manner. (Paying) customers come with the extra responsibility of taking care of them.
The latter can be much harder to manage since you need to react quickly and not push it off until when you have time.
