Nasarius is a specialised treasury and cash management consultancy founded in 2006 and headquartered in Copenhagen, Denmark. The firm advises large Nordic and European corporations on treasury best practices, process optimisation, bank tenders, treasury management system selection, implementation, and integration. Within the SAP product portfolio it focuses on SAP Treasury and Risk Management, SAP Cash Management, and SAP working capital solutions, and it is a registered SAP partner positioned around the office of the CFO. In 2024 Nasarius was acquired by Pearl Group, an SAP partner network in the Nordics with more than 500 SAP consultants. The acquisition combined Nasarius's treasury domain expertise with Pearl's broader SAP banking and finance practice, allowing joint delivery on end-to-end finance transformation projects. Nasarius retains its brand and continues to operate as a focused consultancy rather than a generalist SAP integrator, and its work typically involves either greenfield SAP Treasury rollouts, replacement of legacy treasury management systems, or integration of SAP Treasury with bank connectivity, payment factories, and in-house bank structures. Customers are predominantly large corporates in Denmark, Norway, Sweden, and continental Europe, often as part of broader SAP S/4HANA finance programs.
