In Xend Finance, a group is an entity that holds one or more Esusu and Cooperative cycles. An Esusu cycle has to be created as a part of a group, also a Cooperative savings cycle has to be created as part of a group.
If you intend to create an Esusu or Cooperative savings cycle for others to join, will have to create a group. You can create a group from the Esusu section or the Cooperative savings section. If you want to create Esusu cycles in a group, create that group from the Esusu section, and the same thing for the Cooperative savings cycles.
Whichever section you create a group from, the need details are the same.
