direction on adding customers and receivables

[Michael Tenenbaum]

I would like to use GNC as the accounting backbone for our office 
automation system.  We're using Postgresql as the database.

For this reason I need to know how to:

(1) Add a customer from our application (bypassing GNC)

(2) Add a receivable from our application to the general ledger (bypassing GNC)

Thanks.
