Only one billable issue may be linked to a service order. If you need several billable issues at different points in time, it is recommended to solve that with internal issues and a consolidated invoice, and linking this to the service order.

Billable goods and service are issued in service order documents. An issue document is created for that, so it can be accessed also via Goods | Issue (see also Issuing with documents).

Like with service issue, two methods for achieving this are available:

1) Link with Existing Issued Invoice

In the Billable tab, specify a document in the Link to Document field and click the Link button.

2) Create New Invoice

In the Billable tab, click the Create Document button. A new issued invoice is created in the document type specified in Billable Service/Goods for that service order document type.

No matter how you link billable issues to service order, the Billable tab is used to record all issues from a warehouse. The specific warehouse is set in the service order document type through the Billable Services/Goods field. The same method can be used to invoice any services that the customer is billed for.

Because this creates a separate document, such documents are posted in the same way as issued invoices in the Goods module (see Automatic posting of issued invoices and Automatic posting of materials consumption).
