Clust was created to cut the friction for you and for your clients, customers, candidates, hires, speakers (whoever you work with regularly) when you want to gather from them a list of elements (such as files, documents, payments, esignatures, tasks to be completed) in a particular order or not.
If you need to tell someone as part of a specific process (we call this an application) that they need to take action on many things so you can work, then you can save money and time using Clust.
In other words, if you ever happened to send an email or chase someone so they can:
complete an action, send you documents or files, pay you, sign something, upload more files, check out a document...
You need Clust!
Plus, you'll be compliant with the law regarding data collection.
