With any subscription service, a key consideration is how likely your customers are to remain subscribed to your service. The best way to measure this is to collect feedback from your customers on a regular basis. Sending an AskNicely NPS survey will give your customers a short, easy way to let you know how they are feeling. By triggering the survey after they start their subscription with an optional wait period you can be continuously collecting feedback and keep a realtime gauge on how your customers are feeling about your service.

Note: When setting your wait period, consider the length of time of your subscription renewal and how long it will take the customer to start using your product - for many SaaS businesses working with a monthly billing cycle, it makes sense to wait around 25 days so that you get feedback shortly before the second payment is due. However, for some businesses with a longer onboarding phase, you may want to wait for longer.
