Prerequisite: You must complete HST mapping first.
Go to Administration > Web Admin > HST Adjustments.
In the HST Transaction Adjustment Setup section, from the dropdown list, select an Offsetting debit account for absorbed HST tax increase.
Enter a threshold above which customers are charged for HST tax increases. For example, to charge customers for increases greater than $5, enter 5 in the Charge customer when increase exceeds field. To not charge customers for increases, leave at 0.
If there are A/R amounts created, use the calendar button to specify the Due Date of new payment plans created.
In the Upgrade Processing Selection area, do one of the following:
To process all transactions, select Process all remaining transactions, OR
To process only some transactions, in the numerical field, Enter number of transactions to process.
Click Run Upgrade. When the processing finishes, a message appears in the following format: "FINISHED! Processed x transactions marked as processed on <date>".
If there are outstanding transactions (i.e. you only processed some transactions), click Reset and Process again to reset the transaction counter.
