A_bill_ity is the software platform for order-to-cash processes from FIQAS. It is built from modules that can be used alone or combined: transformation, which validates and enriches incoming data; rating, which applies customer prices and agreements; billing, which covers calculation, generation and distribution of invoices; and collection, alongside subscription invoicing. FIQAS describes the platform as configurable and suited to very large volumes. It is built on .NET Core, Angular and Microsoft SQL Server and integrates through REST APIs. Deployment follows the customer's preference: on-premises, in a cloud, or a private cloud, and FIQAS can also handle hosting with its own facilities or those of partners.
FIQAS is based in Aalsmeer, near Amsterdam, in the Netherlands. It states that it is ISO 27001 certified, completes ISAE 3402 Type II audits every year and that A_bill_ity meets GDPR requirements. Because the deployment model is chosen per customer, the data location depends on that choice and is not fixed on the website. Ownership is not stated, and the platform is proprietary.
