1. A computer-implemented method of formulating reverse accounting entries for a deleted journal, the method comprising: receiving a command, in at least one computer processor operatively coupled to a memory, that a journal is to be deleted; mapping, by the at least one computer processor operatively coupled with the memory, a journal entry in the journal to be deleted to a transaction entry received from a feeder system; determining, by the at least one computer processor operatively coupled with the memory, an identifier key corresponding to the transaction entry received from the feeder system; formulating, by the at least one computer processor operatively coupled with the memory, a reverse accounting entry in a web service message to reverse the transaction entry; and sending, by the at least one computer processor operatively coupled with the memory, the reverse accounting entry with the identifier key corresponding to the transaction entry received from the feeder system in the web service message to the feeder system, wherein the web service message aggregates other reverse accounting entries for other journal entries in the journal to be deleted.
