You can only manage what you measure. Here is the starting set with benchmarks.
NPS (Net Promoter Score). "How likely are you to recommend us, from 0 to 10?" Promoters (9–10) minus detractors (0–6) gives your score. For B2B, 30 and above is healthy. Below 20 is a warning.
CSAT (Customer Satisfaction Score). Satisfaction with one specific interaction. Fires after a call, a meeting or a closed deal. It exposes problems in individual processes rather than in the company as an abstraction.
Churn rate. The share of customers who did not come back within a period. For transactional B2B services, 5–7% a year is generally acceptable. Higher than that needs a structural explanation.
Repeat purchase rate. The share of customers buying again. One of the most underrated numbers in small and mid-sized business: moving it is almost always cheaper than buying more traffic.
CES (Customer Effort Score). How much work it takes to deal with you. Often more predictive than satisfaction — people return to whatever is easy, even at a slightly higher price.
LTV and CAC together. Without this pair the metrics above stay qualitative. Once you can see acquisition cost and lifetime value per channel, service decisions stop being a matter of taste. We showed the calculation in
ROI of a CRM implementation and the channel-level view in
tracking lead cost from messengers through end-to-end analytics.
None of this needs manual collection.
End-to-end sales analytics pushes it all into one dashboard that refreshes itself.
