Manage your customers in the customer overview. You can see all the information you need from the customer, and you can attach an unlimited number of tags to the customer.
With tags, you can associate specific information with a customer. For example, you can determine whether it's a retail sale or a webshop sale. The options are endless.
In addition to the tags you can attach, it's also possible to see what kind of product the customer has purchased. If it's a product with a certain lifespan, you can schedule an email for the end of the product's lifespan, turning a one-time customer into a repeat customer. For instance, you can set up an automatic email with a discount code that the customer will receive in five years, allowing them to purchase the same or a similar product from you.
