Disclosed herein are methods and systems for enforcing dependencies in an account management system using publish/subscribe. Messages containing account information may be published and received by one or more account servicers. Account servicers may not perform account management tasks based on a message unless the message satisfies a keyword, which may express dependencies of the account servicer. Keywords may be based on the content of received messages. If a received message matches a keyword, the account servicer may perform an account management task, and cause a subsequent message to be published with an additional keyword related to the account servicer.
