Hi Donna,
What version of Adagio Receivables are you using?
Reasonably current versions of Adagio Receivables support using a Write-off batch to send net credit amounts to Adagio Payables as a manual check batch, to allow printing a check for a customer. To do this, you have to set up the customer with an associated vendor code from Adagio Payables, then use the Write Off batch function to generate an Adjustment batch for that customer, and choose the option to send to Payables.
Here is a link to a
ShowMeHow training video on how to use Write Off batches in Adagio Receivables, including the sending of customer credit balances to Payables (starting at 2:25). The video in total is only 3:40 in length.
