I get your point about disambiguation. It's just very tricky when working in the SAP world as they don't take too well to variations and such. Btw., I like your option "management of regular customers".

Don't get me wrong. I think your suggestion is a valid one. I am just providing an alternative. So 'management of regular customer (data)' is also Ok in my books.

'Repeat customer' googles on sap.com as well
I don't really trust Googling as a decision criteria.
Surely the nomenclature depends on the SAP client's choice and the type of business.
Furthermore, as we know from Starbucks 'regular' can also mean 'normal' in US-EN.
'repeat' disambiguates this.
@Horst: 'Daten verwalten' is a definite 'manage' in my experience. As far as I understand, this tool is for managing the customer data, not interacting with the customers.

verges on nursing, and so "care" would seem the word -- except would it seem insincere? Would "service" or "support" work? And would "clients" be preferable to "customers"?

All options would work, I suppose. But we're in SAP World here, aren't we? As far as I know, SAP is quite stringent about their terminology. The term "regular customers" is a given. Just google it in connection with sap.com. The rest is flexible, e.g. a tool for managing regular customers etc.
