I've had places offer to just not bill for a few months while still allowing full access or offer some steep discounts in the workflow for cancelling in attempt to reduce churn.
Growth = New Customers Acquisition - Churn. New customers are expensive for many businesses to get, they have marketing, sales, and promotion related expenses. It makes sense to spend money to reduce churn too, because it’s a cheaper way to boost your growth rate.
If you offer deals to reduce churn, you need to focus on if those deals are just delaying inevitable churn or if they are actually winning back customers. Delaying churn is just a game of spending money to make your books look better for a quarter.
IB growth can fuel business growth, especially during times of low new customer acquisition and or high to moderate churn
