Invoice Schedule


Invoice Scheduling enables you to plan when and on what basis to bill clients.


Sending your invoices out on time and the ability to forecast revenues is vital for the smooth running of your business.  


V1 Project Accounting’s invoice scheduling functionality enables you to easily manage these processes.


To create an invoice schedule in V1 Project Accounting you need to set up a system of Invoice Rules that detail how much and when the client should be invoiced.  


The invoice rule type determines whether a project is billed on a fixed fee basis or a time and costs recharge basis.
