The Customer Success Dictionary of Reference: Part II
A glossary of common customer success terms: subscription revenue, cross-sell, customer lifecycle management, deployment, adoption, KPIs, and risk factors.

TL;DR
- A cross-sell means selling a different product to a customer (lateral growth), while an upsell expands or increases revenue on a current offering.
- Customer Lifecycle Management is the practice of understanding and facilitating the full customer journey, from sales through onboarding, engagement, and beyond.
- Adoption has two meanings in customer success: the number of users at a customer organization who use the product regularly, and the uptake of new product features across that organization.
What are the Definitions of Customer Success Terms? - Part II
You asked and we listened! After the positive response to our âCustomer Success Dictionary of Reference: Part Iâ post, we wanted to provide further opportunities for education and growth. In this post, weâll dig even deeper into some common customer success terminology and phrases that many teams utilize every day. Although the exact term names might differ between specific organizations, verticals, or industries, the main ideas remain consistent throughout. Letâs take a look:
Subscription Revenue
Todayâs SaaS organizations commonly utilize a subscription business model, where customers pay a recurring fee to gain access to a certain software or cloud-based platform. Subscription revenue refers to the overall amount of incoming revenue from customer subscriptions over a set period of time. Customer success teams should track subscription revenue over time to keep tabs on big-picture customer accounts and relationships. Itâs also important to remember that subscription revenue doesnât make up 100% of an organizationâs revenueâthere are also non-subscription services like training, customization, or professional services.
Cross-Sell
Cross-sell is a customer success term that refers to selling a different product or offering to a consumer. A cross-sell differs from an upsell, which often increases incoming revenue or expands on a current product offering. Cross-selling has more to do with lateral growth, or switching between one product and another. Itâs often a sign of complete trust between a customer and a brand to attempt a cross-selling transaction, as it often requires a Customer Success Manager (CSM) presenting an entirely new workflow to a customer and them accepting the suggestion wholeheartedly.
Green Zone Status
For SaaS organizations that rely on incoming Subscription Revenue (see term #1) and recurring revenue, Green Zone Status refers to revenue numbers that are trending positively. Green Zone Status is oftentimes represented graphically to make it easy for customer success professionals to quickly identify where âred zonesâ are occurring. Many customer success teams monitor Green Zone Status to stay in-the-know exactly when a customer account starts trending downwards and immediately begin building a plan.
Customer Lifecycle Management
The customer lifecycle refers to the entire customer journey, from sales to onboarding to engagement and beyond. Customer Lifecycle Management, then, is the understanding and facilitating of this process to ensure the perfect customer experience every single time. CSMs should track and learn what they can from every single customer journey and then work from best practices or benchmarks to optimize the customer journey for every individual and organization alike.
Deployment
Deployment is a stage in the customer lifecycle that is often lumped in with onboarding a customer, although itâs actually itâs own step. Deployment is any change on the back end of a platform or product, and occurs when a customer begins using a platform for the first time, as well as when a vendor organization needs to update code behind the scenes. For sophisticated SaaS organizations, deployment is a seamless transfer of data between an online host and the pre-built platform.
Adoption
Adoption is a customer success term with two possible definitions associated with it. On one hand (and probably most commonly), adoption can refer to the number of internal employees at a customer organization who use a SaaS product on a regular basis. As product usage spreads from the decision makers to the end users, the user adoption can be easily measured. However, adoption can also refer to the adoption of new product features by an entire organization. Just as product usage can spread throughout individual customers, an organization can spread itâs use case across an entire platform, slowly adopting all of the features and use cases it offers.
KPIs (Key Performance Indicators)
Key Performance Indicators, or KPIs, are an extremely important for any team or department in any organization, not just SaaS companies. While this blanket term is standard, however, the actual KPIs tracked often differ throughout teams, departments, and organizations. Thatâs one of the perks of KPIs, actuallyâbeing able to track exactly whatâs important to a specific team, without being bogged down by unnecessary metrics. Customer success teams can track KPIs like engagement, usage, and even satisfaction.
Risk Factors
Risk factors is another customer success phrase that can be called different things depending on the team. Risk factors are anything that can possibly stand in the way of a customer succeeding or renewing with a vendor. Also known as âred flagsâ or âroadblocksâ, risk factors are predetermined issues blocking the path to success. Customer success professionals can proactively identify these risk factors early and then work to remove any obstacle or potential of these risk factors occurring.
