An adjustment transaction is an automatic transaction equal to the difference between cash shift's Expected and Actual balances. Poster adds this transaction after closing the cash shift.
Expected balance is location's revenue according to Poster reports.
Actual balance is an actual shift closure sum mentioned by cashiers.
☝️ In case the Actual balance is lower than the Expected one, Poster creates an adjustment to update the cash amount transferred to your financial accounts. By default, this transfer equals the cash shift's Expected balance.
