| Overview  Understanding Invoice processing | 1. | Invoices are generated on a bill term by bill term basis. | 
| 2. | Multiple bill terms can be posted under one invoice number via the use of an invoice group. | 
| 3. | A project can be invoiced only once with an invoicing run. If two invoices for a project are to be generated within one billing period, the first must be posted prior to generating even the draft for the second. | 
| 4. | Invoices can be sent to separate A/R accounts. | 
| 5. | Invoice runs can be filtered by labor only or expense only. | 
| 6. | Invoice runs can be filtered by project leader. | 
| 7. | Invoice runs can be filtered by user-defined billing groups established at the Bill Terms Node. |
