A focused SAP practice, not a generalist IT shop

Siratek is a consulting firm that works only on SAP enterprise environments. We work with organizations that run their financial and operational processes on SAP, and we stick to hands-on functional work instead of general IT support.

Our practice covers SAP S/4HANA consulting and support in general, with particular depth in FI-CA (Contract Accounts Receivable & Payable) and CFM (Cash & Financial Management). Utilities, insurance and telecom companies rely on these modules to run high-volume billing, collections and treasury operations.

Engagements usually span the whole lifecycle: implementation and migration, functional support, maintenance and evolutives, and AMS support once a system is in production.
