It can be difficult to take over a position without adequate training. When working with your dealer, you are entitled to insist on getting full answers to your questions. After all, you're the one signing the cheques! One technique is to build a list of questions and send them to your dealer. Maybe some can be answered by email and maybe some require a site visit.

The 1-hours webinars are a good way to get an introduction to Adagio.

Another way that the subledger could be out of synch with the control account is when Retrieving subledger batches to the GL. This could happen if you choose to "Assign entries to" a "Specific period" rather than "Period based on date",
