# License parameters

> License parameters in ABBYY FlexiCapture: serial number, station and page limits, processing options, and the custom components needed for invoice capture.

Each license has its own serial number. A license includes a set of parameters that determine whether the user has the right to perform certain document processing operations.

* **Description** — Serial number, licensing method, availability of a virtual machine
* **License purpose** — License type (software or hardware), ability to provide document processing services
* **Workstations**, **Tools** — Restrictions on the number of stations and development tools (FlexiLayout Studio, FormDesigner).\
  **Note:** Depending on the license type, restrictions on the number of stations can be specified either separately for rich and Web-stations or together for both types of stations.
* **Productivity** — Restrictions on the number of pages and CPU cores. The **Page limit** group displays both the total quantity of pages allowed for the license and the number of pages available at the moment.
* **Processing** — Additional document processing parameters: the use of FlexiLayouts, a limit on the amount of fields, and additional recognition languages\
  **Note:** A license with a limit on the amount of fields in Document Definitions precludes the use of table fields and repeating fields in projects.
* **Custom components** **(including Document Definitions)** — The use of components developed by the user
* **Import** — Additional import options; specifies whether the ISIS protocol and the opening of PDF files are allowed
* **Export** — Additional export options; specifies whether export to [searchable PDF](/flexi-capture/appendix/work-with-pdf) and advanced XML export are allowed

## Components for invoice processing

For you to be able to process invoices, **Custom components** must include one or more components from an **ABBYY HQ** vendor or the **Invoice AU** component from **ABBYY AU**:

* **EuropeanInvoice** — For European invoices
* **USInvoice** — For American and Canadian invoices
* **ANZInvoice** — For Australian and New Zealand invoices
* **JPInvoice** — For Japanese invoices
* **CommercialInvoice** — For commercial invoices
* **Receipt** — For receipts
* **Orders** — For orders

The **EuropeanInvoice.AddOn.LineItems**, **USInvoice.AddOn.LineItems**, **JPInvoice.AddOn.LineItems,** and **ANZInvoice.AddOn.LineItems** components allow you to enable Line items extraction.

The **ABBYY EU: Business Monitoring** component allows you to enable the [business process monitoring](/flexi-capture/web-stations/monitoring-console/mmc-monitoring-business-process) feature.
