Systax has been attracting attention from other major players besides SAP. For Systax, a medium-sized company, this opens doors to reach larger clients, users of SAP solutions. In the following years, SAP developed the company's channel in the country, which gained momentum with the introduction of S/4, the new SAP ERP, which already has native integration with Ariba. The solution entered SAP's portfolio in 2012, when the German multinational bought Ariba for USD 4.3 billion. The agreement with Systax is a milestone for Ariba in the country. Service pricing and integration with Ariba's auction system are also on the roadmap. It can also be integrated with S/4 Hana, bringing Systax's data source into the ERP as well. Procurement Compass will implement the system, an API that SAP says is easily integrable with Ariba, with an average time between two and three weeks. The first tax calculation engine for the SAP Ariba Sourcing platform also had the involvement of Procurement Compass, a company founded by procurement professionals in 2017. It is also performs calculations of taxes due and identifies potential tax errors that could lead to future fines.

The engine makes it easier to see which taxes incur on each tender, both from the full price received in tenders, and to predict which taxes will incur on a net price. This new feature will allow Ariba clients to have access to 22 million tax rules that are updated daily, facilitating the work of tax specialists, who currently calculate taxes manually, slowing down the purchase flow. Ariba, SAP's e-procurement software, has teamed with Brazil-based tax intelligence company Systax in order to use their tax calculation engine.
