Invoicing

My question about invoicing is when doing them manually when you need to and involving a multiple unit account, why can't SiteLink allow me to group all units from an account on one invoice as it does when auto generated? Some companies we have vendorship with do not want two or three invoices for one account but want them all on one invoice. Is there a fix for this? 

I have an account set up for  (print) invoice to be processed a few days earlier before everyone else's so they can get payment in on time. But it never pops up for me to process I always have to manually add the invoice. Dealing with 700+ units sometimes I might forget and their invoice gets sent out late. How can this issue be fixed? 

I have the same problem as BReeZy.  I'm sure every storage company has this problem with multi-unit tenants.  The terrible response from Sue_C sounds like a brush off.  Why not let us, as owners of the facility, decide if we want to manually send one invoice with multiple units on it?  The auto invoicing does it.  So your response doesn't hold water.  Please give us a button that says "Send a Multi-Unit Invoice"
