In order to merge subscription A into subscription B follow the steps below:
Look up the number of issues remaining and the Deferred Income (cash) for the active order in subscription A.
Transfer the Deferred Income (cash) from the active order in subscription A to the active order in subscription B.
Adjust the active order in subscription B so that its term includes the issues that were remaining for the active order in subscription A. Also adjust the active order in subscription B so that the price includes the Deferred income (cash) from the active order in subscription A.
Cancel subscription A.
Check 'Date of last notice' and 'Last notice number' fields for the most recent order in subscription B. Since you have just increased the term on Subscription B, you need to make sure that this renewal information is still correct.
If the order uses a "by days" renewal series and the first renewal notice has already been sent, then QuickFill will send out the next notice when the specified number of days since the last notice has passed. You can adjust the 'Date of last notice' and 'Last notice number' fields on the 'Billing & Renewal' tab of the 'Adjust order' transaction. To restart the renewal series, remove the values in these fields.
If the order uses a "by issue" renewal series, QuickFill will send out a renewal notice based on the issues remaining and no adjustment is necessary.
The 'Duplicate subscriptions' report (located under 'Reports', 'Customer lists') provides a list of customers who have more than one subscription to the same publication.
