The number of plans depends on your integration requirements and cannot be 100% determined a priori without knowing your specific requirements.
As a rule (not in all cases) it can be said that you need as many plans as you want to establish connections or synchronisations between systems/endpoints. In some cases, however, it makes sense to set up several plans between two systems.
Pricing is based on the number of plans, API calls, groups and relations. We thus price the value of your synchronisation. The more and more intensively you use the HubEngine, the more likely it is that the price will rise. However, our tariffs offer you the possibility of using the price tariff that is best for you. We’ll even actively recommend a higher rate if it saves you money.
