A RAG + ServiceNow chatbot for SMEs usually costs €12,000 to €46,000 depending on integration depth, knowledge quality, and security model. Monthly running cost is commonly €300 to €980. This is one of the highest-ROI internal AI use cases because it targets repetitive support requests, ticket triage, and faster incident resolution.
Why ServiceNow + RAG Works for SME Operations
ServiceNow already contains incidents, categories, and process context. RAG adds the missing layer: fast retrieval from runbooks, SOPs, internal documentation, and historical resolutions. Together, this creates an assistant that answers accurately and supports the support team, not just end users.

ROI Example
If your internal support team receives 1,500 repetitive requests monthly and the assistant resolves 50% automatically, you reduce 750 manual interactions. At €4 to €7 handling cost each, that is €3,000 to €5,250 per month in direct savings.
