CAC Payback Period is the time it takes for a company to earn back their customer acquisition costs. The value depends on how high the Customer Acquisition Cost (CAC) is and how much a customer contributes in revenue each month or each year.

Call Volume is the count of both incoming and outgoing calls handled. It can be used to measure the number of incoming calls to a Customer Support organization, outgoing calls from a Sales team, calls queued to an Automatic Call Distribution (ACD) service, and dropped calls. Tracking this metric helps you determine required staffing levels and understand customer behaviour.

Call-in Rate is the average number of inbound calls received per paid user of a product or service. It is used to monitor changes in call volumes, which can be an early warning sign of product or service issues, and even potential churn.

Campaign Cost per Goal Conversion is the amount of money spent on an ad campaign, also called Campaign Spend, that leads to a goal conversion. It is used to measure the costs involved in the success of an ad campaign which consists of several ads with a single business objective.

Contact to Customer Conversion Rate is the percentage of contacts that have converted to sales. Contacts can be past or existing customers, or qualified leads. This is an important metric to track in the sales funnel because it quantifies how efficiently the sales process secures and grows existing customer relationships.

Contacts are individual people that the business has a relationship with, often associated with an account. In many Customer Relationship Management Systems (CRMs), such as HubSpot and Salesforce, Contacts are associated with qualified opportunities, existing customers, or past customers. Leads are usually not counted as Contacts.

The Cost Of Goods Sold (COGS) is the measure of direct costs incurred by a company to manufacture or deliver their product or service. Costs typically include raw material and direct labour, but this varies from business to business, depending on the products or services that are being sold. COGS is the building block to understanding Gross Margin and Gross Margin Percent.

Cost per Activated Lead measures the costs involved in generating one activated lead. An activated lead is a potential customer who demonstrates intention to purchase your product.

Customer Acquisition Cost (CAC) is the cost a business incurs to acquire a new customer. This includes the fully loaded costs associated with sales and marketing to attract a potential customer and to convince them to purchase, divided across all new customers.

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.

The Customer Lifetime Value (LTV) metric indicates the total revenue a business can reasonably expect from a single customer account. It considers a customer's revenue value and compares that number to the company's predicted customer lifespan. Businesses use this metric to identify their most valuable customer segments.

CSAT is a measure of the level of satisfaction that a customer has with a company’s products and/or services, most often provided by the customer as part of a survey. It is commonly used as an indicator of a customer’s loyalty to a company.
