We have been collaborating with Paraplan for about a year now. We haven't encountered any serious problems, and if difficulties arose, we reached out to customer support. They operate on weekdays during business hours, so responses to some inquiries weren't always quick. Overall, the support is commendable: they are accommodating, explain things, and help resolve issues that come up. The functionality is quite simple, as Paraplan is geared towards small training centers, fitness clubs, and similar organizations. You can create personal accounts for clients and subscriptions. Everything else is standard – sales funnel, mailings, telephony integration, access rights distribution, and reporting. The overall impression is positive. The system works smoothly and without errors. Although some reports are lacking, the existing ones allow for the necessary data to be created through another application. The interface may not appeal to everyone, but it is simple and user-friendly.
