Hello. I created three different supplier invoices and I don't see their payable amount in the Parties form. The amounts do show up in the Chart of accounts.
One of the invoices has only one product, another one has services and unregistered products (I just wrote a description, price, etc.), and the last one has a service. All the invoices have a payment term of 2 weeks and 4 days. In all cases, the invoice date was set to 21/06/2015 (more than one month ago). All of them have a Posted status. In the invoice form, you can choose the Payments tab, and see that there is an amount to be paid. I am using the Colombian chart of accounts. I do see amounts if I create a new database with a minimal chart of accounts. However, there is no such amount in the list of Parties. What could be wrong? I don't think that it has to do with the Colombian chart of accounts, could it be?
