‘Containers under management’ refers to the maximum total number of containers you lease and supply through xChange at the same time. ‘Basic’ plan users are automatically upgraded to the ‘Professional’ plan once you manage over 10 containers. If you’re on the ‘Professional’ or ‘Enterprise’ plan, you can add batches of 100 containers for $249 each upon reaching your limit.
Please note that while the quantity of containers you can supply is primarily limited by your ‘Containers under management’ plan, the number of containers available for you to lease is subject to risk assessment conducted by xChange.
