The ACS Contributions module maintains complete giving records for all contributors. These records include both regular contributors with and without pledges and one-time givers.

The Contributions module integrates with the individual records of the ACS People module, eliminating the need to enter contributor records twice. You can also configure the Contributions module to post your general ledger distributions directly to the ACS General Ledger module, and you can enter pledges at any time during the year.

Make sure your batches only include transactions with dates in 2015.
Transactions with a posting date for next year must go in a separate batch. So, your
2016 batches should not have any 2015 contributions.
