Invoicing and retention

Invoicing and retention - a project manager prepares source documents for invoicing either on the basis of a job log or given periods. The documents are passed on in a form of a request of invoicing which, aside of basic data, also contains requested enclosures, advances list and a retention structure related to the invoice.

Retention can be defined either at invoice preparation or at any time after it is posted. Each retention item has an individual due date and is posted individually in the system. The system includes built-in notifications of oncoming due dates of retention in the form of notification e-mails to responsible persons.

All purchase invoices regarding the project may require an authorization using either internal work flow processes of the information system or integration with MS SharePoint. At confirmation, a relation to a project is input (to assign direct costs), a relation to price calculation line (for a comparison of planned and actual costs), a relation to a cash flow line (for a comparison of planned and real outcomes) and an allocation of retention.
