Hi Sheri (sorry if I have the spelling wrong),
Tech Support is right, however...
Converting your statements from an accrual to a cash basis is really a simply matter of backing out the expenses from unpaid invoices. Since Adagio keeps track of the g/l transactions of the invoices you'd posted, you could created a report using Crystal Reports for Adagio that listed all the outstanding invoices and the ledger accounts they referenced. Use this report to create a batch to post into ledger. Before you post this batch, copy it, reversing the signs to restore the expense entries.
Does that make sense?
