Manual Invoices can be generated, as well as rules based charges.

All data entered into Sales Invoices is checked against the database and totals automatically summarised for Project and Client.

Purchase Orders are used to create fully audited requests for goods and services

You can analyse exactly what you have spent, or plan to spend, your organisation's money on, how much you have spent against each Supplier, and who raised the Orders.

Both Sales and Purchasing allow you to set approval and value limits so that specific individuals can only raise work up to a set value, or must have their Orders approved by a  line manager.
