It will be a great add on if the next versions of Sage could have a functional relationship between <Invoice's Module and Customer's Modulethe >, therefore to be able to select from customer's module a subset of records (lets say those with balances on 60+days, 90+days older) and from this list or subset run an INVOICE layout report that will email to each customer all their overdue invoices, multiple pdf file attachments (one per invoice)
