Your Level 1 agent is stuck on a complex technical issue. Your VIP customer is threatening to leave. A critical bug is crippling dozens of users. What should you do? Escalate.

Escalation is an essential mechanism in customer service, but if not handled properly, it can become a nightmare. In this guide, learn everything you need to know about support escalation: definition, types, and best practices for using it effectively.

Support climbing: definition

Escalation support is the process by which a customer request is transferred to a higher level of expertise or authority when the initial agent cannot resolve it.

Climbing can be:

  • Functional: towards a technical expert
  • Hierarchical: to a manager or supervisor
  • External: to a partner or supplier

It is a safety net that ensures that every request is answered, even the most complex ones.

Types of climbing

Functional climbing (horizontal)

Referral to a specialist or team with specific expertise.

Examples:

  • Level 1 support → Level 2 support (technical)
  • General Support → Billing Team
  • Agent → Developer for a bug

This is the most common escalation. It allows the request to be routed to the right person with the right skills.

Hierarchical (vertical) escalation

Transfer to a superior when the situation requires it.

Examples:

  • Unhappy customer who asks to speak to a manager
  • Request for significant commercial gesture
  • Crisis situation requiring a quick decision

She often intervenes in matters of authority or decision-making.

External scaling

Transfer to an entity outside the company.

Examples:

  • Escalation to the publisher of third-party software
  • Escalation to a supplier or partner
  • Escalation to external legal counsel

When to climb?

Legitimate reasons for escalation

  • Lack of technical expertise: the problem exceeds the agent's expertise
  • Lack of authority: the required decision exceeds the agent's prerogatives.
  • SLA exceeded: the deadline is approaching and resolution is not progressing
  • High-risk customer: VIP, sensitive situation, risk of churn
  • Systemic issue: bug affecting multiple clients

Warning signs

  • The customer becomes aggressive or threatening
  • The problem is recurring with no lasting solution.
  • The agent has been going around in circles for more than X exchanges.
  • The customer explicitly requests to speak to a supervisor.

The escalation process

1. Evaluation

The agent determines whether escalation is necessary and justified. Have all Level 1 resolution options been exhausted?

2. Documentation

Before climbing, the agent clearly documents:

  • The initial problem and context
  • Actions already attempted
  • The information collected
  • The reason for the escalation

3. Transfer

The request is assigned to the correct recipient with all documentation. The customer is informed of the transfer.

4. Follow-up

The initial agent can remain on copy to follow the resolution and learn.

5. Feedback

Once resolved, returning to the initial agent allows for improvement of skills for similar cases.

Support levels

Climbing is organized into a structure of levels:

LevelRoleSkills
Level 0Self-serviceFAQ, chatbot, knowledge base
Level 1Base supportFrequently asked questions, standard procedures
Level 2Advanced supportTechnical issues, complex cases
Level 3ExpertiseDevelopers, engineers, specialists
Level 4ExternalPublishers, partners

Each level has different skills and costs. The goal is to solve at the lowest possible level.

Automatic scaling

Modern tools allow certain escalations to be automated:

SLA escalation

If a ticket is approaching its SLA limit, automatically escalate it to a senior agent or manager.

Keyword escalation

Detection of sensitive terms ("lawyer," "cancel my account," "refund") that trigger an escalation.

Climbing on feeling

AI detects a frustrated or angry customer and automatically escalates the issue.

Klark can accurately analyze the sentiment of conversations and trigger intelligent escalations when the situation requires it.

Measuring escalation

Escalation rate

Formula: (Escalated tickets / Total tickets) × 100

Target: 10-20% is generally healthy. Too low may indicate a lack of rigor, too high may indicate a Level 1 training issue.

Climbing time

Time between ticket creation and escalation. Too long indicates hesitation to escalate.

Post-escalation resolution rate

Are escalated tickets actually resolved by the higher level?

Return to initial level

If many escalated tickets return to level 1 ("it wasn't for us"), there is a problem with the criteria.

Mistakes to avoid

Mistake #1: Climbing too fast

Climbing without attempting to solve creates overload at higher levels and deprives the agent of learning.

Mistake #2: Escalating too late

Waiting too long frustrates the customer and can cause SLAs to explode. Knowing when to escalate is a key skill.

Mistake #3: Escalating without context

"I'm transferring this ticket to you" without documentation = a waste of time for everyone and the customer having to repeat everything.

Mistake #4: No follow-up

Escalate and forget. The initial agent must follow up to ensure that the customer is taken care of.

Mistake #5: Escalation as an escape route

Using escalation to avoid difficult customers rather than for genuine competency reasons.

How to reduce unnecessary escalations

1. Improve your training for Level 1

The more competent your agents are, the less they need to escalate issues. Invest in ongoing training.

2. Document procedures

A comprehensive knowledge base enables agents to find solutions without escalating.

3. Give them more autonomy

If escalation is often used to "request authorization," expand the prerogatives of level 1.

4. Analyze patterns

A lot of escalations on the same subject? Create a procedure or provide specific training on this point.

5. Use AI as your co-pilot

AI suggestions enable agents to resolve cases that they would otherwise have escalated.

Frequently Asked Questions

Does escalation impact the FCR?

Yes, an escalated ticket is by definition not resolved on first contact. But a relevant escalation is better than a bad resolution.

Should the customer know that they are being escalated?

Yes, transparency. Inform him of the transfer and the estimated time frame for processing.

Who is responsible for the escalated ticket?

Generally, responsibility passes to the level that receives the escalation. But the initial agent can keep an eye on things.

Do you need approval to climb?

Not systematically, as this would slow down the process. But clear criteria must be defined.

Conclusion

Escalation support is an essential mechanism, but one that must be used judiciously. When managed well, it ensures that every customer finds a solution. When managed poorly, it overloads teams and frustrates customers.

The keys to successful climbing:

  • Define clear criteria for each type of escalation
  • Document everything systematically before transferring
  • Train Level 1 to reduce avoidable escalations
  • Automate critical escalations (SLA, sentiment)
  • Measure and analyze escalation patterns
