We are planning to create a copy of our company file for practice/learning purposes.  It will be used for the entire A/R workflow, so employees will understand Sales (work) Order-Invoice-Receive Payment.   

We would like to fully simulate receiving payments for fake invoices.   I understand how to create a dummy bank account; however, am not certain what of the best option for the test payment.    

Suggestions?  or link to a good article about it.
