Do you know Panera, a restaurant chain in the US? They recently offered a $8.99 coffee monthly subscription. Customers can take unlimited coffee under this offer.
They decided to offer this program after a few months of testing. They saw more than 200% increase in the frequency of visit, which is expected. The best part is there have been about 70% increase in food attachment. It’s like they use marketing money in this subscription offer to sell their core product which is food.
Can you add a subscription model to your product or part of your service? If you can and want to, I suggest you to build a strong financial model to justify it. A wrong calculation could cause a major issue.
