Which plan is right for my business?
We have a plan for every type of business. The main decision is based on your company’s number of clients and the traffic you’re able to generate on your websites or private areas. The more clients you have, the more simulations will be performed, and the more necessary it becomes to better track your clients’ behavior. Review FEXER’s plans to learn more about all the features included in each plan.
What if I exceed the monthly simulation limit?
Each plan has a monthly simulation limit. If this limit is exceeded, each additional simulation is charged at a set price. If this limit is regularly exceeded, it is recommended to upgrade to a higher plan, which has a higher simulation limit.
How does the analytics service work?
