Gross Revenue Retention (GRR) Rate is the percentage of recurring revenue retained from existing customers in a defined time period, including downgrades, and cancels. It does not include any expansion revenue. GRR is also commonly referred to as Gross Renewal Rate.

Total Addressable Market (TAM) is a measure of the revenue opportunity of capturing 100% of the market for a product or service.

Customer Effort Score (CES) is a measure of how easy or difficult it is for customers to interact with your company, for example, to make a purchase, to access a free trial, to resolve a problem, to navigate your website, or to get something done in your product. It’s measured by surveying customers after a specific interaction, and asking them to rate how easy or difficult it was to do what they wanted to do. Examples of difficult or high-effort interactions are ones that add friction for customers, for example, making them repeat information, interact with multiple people or screens, or wade through generic content to find information relevant to them.

Time to Value (TTV) measures the duration between when a user selects your product and the moment they initially realize the value of your product. Value usually means that the setup process is completed and the first usage of the product is successful.

A Customer Health Score is a single, calculated number that reflects a customer’s health across multiple dimensions. By monitoring Customer Health Scores, you can detect early signals of increased friction or declining customer engagement. You can also identify highly engaged and loyal clients, who would make excellent advocates.

Annual Contract Value (ACV) represents the normalised dollar amount an average customer contract is worth to your company over one year. Unlike other SaaS metrics such as Annual Recurring Revenue (ARR), there's less universal consensus on ACV's precise definition across the industry. Some companies include one-time charges like setup fees, implementation costs, or training in their ACV calculations, while others exclude these non-recurring elements to focus purely on the ongoing contractual commitment. This variability makes it essential for sales and finance teams to establish clear internal definitions and remain consistent in their calculations to ensure meaningful trend analysis and benchmarking. The metric serves as a crucial indicator of your company's market positioning, customer segmentation strategy, and overall business model effectiveness. ACV directly influences your go-to-market approach, sales team structure, customer success investments, and pricing strategy. Companies with higher ACVs typically employ different sales methodologies, longer sales cycles, and more comprehensive customer onboarding processes compared to those targeting lower ACV segments.
