SIP Management (Coresuite)

E-invoicing in Germany: How to implement the obligation with SAP Business One

SIP Management This is the Service Intervention module of the Coresuite family and covers the lifecycle of a service intervention process in SAP Business One: from the customer's request, through scheduling, technician deployment, feedback, and finally invoicing. It integrates the SAP B1 service modules (Service Calls, Service Contracts, Equipment Master Data) with a job scheduling system and a mobile feedback component for field service technicians.

Context

In day-to-day operations, SIP Management controls the conversion of service calls into tangible assignments: the dispatcher sees capacity planning per technician and day, assigns tasks, generates work orders with spare parts lists, and the technician documents working time, materials used, photos, and customer signatures on-site. Upon feedback, working times are transferred to service contracts or customer invoices – depending on the coverage type (warranty, fixed price contract, billable) – and the service call is closed accordingly. Technically, the module is based on Coresuite. Framework, utilises its own UDTs and UDOs for deployments and technician capacities, and integrates with external tools like mobile apps or customer portals via the B1if scenario or the Service Layer.

Demarcation

SIP Management does not replace SAP B1 service calls as such – it builds upon them and adds the deployment perspective. Compared to full-fledged Field Service Management platforms like SAP Field Service Management (formerly coresystems.cloud), the scope of functions is leaner and tailored for B1 medium-sized businesses. And it is not a CRM: Opportunities, leads, and marketing campaigns remain in SAP B1 CRM or in upstream systems like HubSpot. If you want to use a full field service suite in addition to SIP, you should decide early on which system will take the leading role for deployment scheduling, spare parts, and service contract billing.
