Hi Morris,

There are a few reasons why this might happen.  AutoDebit contains a safety check on the Claims tab when you're viewing a customer.

The claims safety check will block anyone from making a claim if:

• You have other customers with claims under the same postcode and/or full customer name. (This is to prevent serial fraudsters registering multiple customer accounts in order to create more claims).
• Their payments are not up to date. (This check basically fails if the 'Next Payment Due' date is in the past for an active Service),
• They don't have any active Payment Methods on their Services.

Note that customers might fall outside of the second two rules above if they are within a free trial period. 

Once you have made sure your customers don't fall under the above descriptions, you should be able to create claims for them.

Best wishes,

Adam
