What is customer success?

Customer success helps your clients reach their goals using your product. It’s proactive, not reactive.

The goal is to make sure customers get so much value that they never want to leave.

The core principle

If customer support fixes what’s broken and customer service answers questions, then customer success makes sure customers thrive.

Key responsibilities of a customer success team

While the specific duties of a customer success team can vary, they generally include the following:

• Client onboarding: Guiding new customers through the initial setup process and helping them understand how to navigate the product to meet their unique goals.
• Customer education: Providing training and resources to ensure customers fully understand the features and functionalities of the product, empowering them to make the most of it.
• Customer relationship management: Serving as the primary point of contact for clients, customer success team members work to build strong, long-term relationships that foster loyalty and turn customers into brand advocates.
• Proactive support: Regularly engaging with customers to identify potential issues early and address them before they affect the customer experience.
• Upselling and cross-selling: As relationships evolve, customer success teams identify changing customer needs and suggest relevant product upgrades or additional services that enhance the customer’s experience.
• Feedback gathering: Collecting customer feedback during interactions to uncover needs and areas for improvement. This information can be shared with the product team to refine offerings and improve customer satisfaction.

What is customer service?

Customer service answers general questions and solves non-technical problems. It’s reactive and triggered when customers reach out.

The goal is to make every customer interaction positive, whether they’re buying or need help
after purchase.

If it’s a general question or transaction, it’s customer service. If it’s a technical problem with the product, it’s customer support.

Key responsibilities of customer service teams

• Responding to customer inquiries: Addressing customer questions or concerns related to products, services, policies, and procedures. These inquiries are handled through phone, email, chat, or social media channels.
• Addressing and resolving issues and complaints: Ensuring customer concerns or complaints are addressed quickly, professionally, and efficiently, turning negative experiences into positive ones.
• Escalating issues and complaints: When a situation cannot be resolved by the customer service team, it’s their responsibility to escalate the issue to a higher level (e.g., management) and ensure that it is resolved.
• Collect feedback: Gathering customer feedback about their experiences to share insights with relevant stakeholders, helping improve products and services over time.
• Maintaining customer records: Keeping accurate and updated records of customer interactions to ensure consistency, especially if a different customer service representative needs to assist the same client in the future.
• Order management: Handling processes related to orders, such as tracking, returns, exchanges, and refunds, depending on the product or service offered, to ensure smooth and efficient transactions.

What is customer support?

Customer support fixes technical problems with your product. It’s reactive and triggered when something breaks or doesn’t work right.

The goal is to get your product working properly as fast as possible.

The key difference

Customer Service helps with questions and transactions. Customer Support fixes technical problems.

Key responsibilities of customer support teams:

• Technical assistance: Providing support to customers experiencing technical issues by helping them troubleshoot problems, resolve technical difficulties, and guide them through specific processes.
• Product problem solution: When customers encounter product-related issues, customer support teams step in to restore full functionality and ensure the product performs as intended.
• Documenting customer issues and solutions: Keeping records of customer problems and the solutions provided allows the team to identify recurring issues and potential product improvements. It also provides a reference for follow-up interactions with customers.
• Providing guidance and solutions: Offering step-by-step guidance to help customers overcome technical or product-related challenges, enabling them to use the product effectively.
• Collaborating with other departments: Customer support teams frequently collaborate with customer service, customer success, and product teams to address recurring technical issues and ensure seamless product improvements.

Top metrics for measuring customer success, service and support

Establishing metrics to measure customer service, customer support, and customer success is essential. These metrics enable teams to evaluate individual and overall performance, identifying areas of strength and opportunities for improvement.

The primary goal of the metrics for each department is as follows:

• Customer success metrics evaluate how effectively customers are reaching their goals using your product. 
• Customer service metrics measure how well your customer service team addresses inquiries and resolves issues that clients encounter with your product or service, contributing to a positive experience. 
• Customer support metrics focus on how efficiently your support team manages technical issues and product-related challenges.
