The INVOICES menu is a collation of all the INVOICES created in BM and this menu can be used to either:
1. Search for an Invoice
2. Create a new Invoice
NOTE that most invoices are created from the following:
1. From the Progress Claim in a Fixed Price job
2. From the Site Summary in a Cost Plus job
3. From the Lead form to qualify a prospect
However you are able to create an Invoice through the INVOICE menu should you the need arise
