Your customer starts with a message on Instagram, continues by email, then calls to follow up on their request. Do they have to explain everything again each time? If so, you have anomnichannel problem.

In this guide, discover what omnichannel really is, why it has become essential, and how to implement it in your customer service department.

Omnichannel: definition

Omnichannel refers to an approach where all customer communication channels are integrated and synchronized, providing a seamless and consistent experience regardless of the point of contact.

Customers can switch between channels seamlessly: their history, context, and request follow them.

Omnichannel vs. Multichannel: What's the Difference?

These two terms are often confused, but they refer to very different realities:

AppearanceMultichannelOmnichannel
ChannelsMultiple channels availableMultiple integrated channels
DataSilotées by channelUnified and shared
ExperienceDifferent depending on the channelConsistent everywhere
HistoryTo be repeated at each contactAutomatically tracked
Customer visionFragmented360°

In summary: multichannel means being present everywhere. Omnichannel means being consistent everywhere.

Modern customer service channels

Traditional channels

  • Phone: always preferred for emergencies and complex cases
  • Email: asynchronous reference channel, perfect traceability

Digital channels

  • Live chat: responsiveness of the telephone, convenience of digital technology
  • Chatbots: available 24/7, handling simple requests
  • Web forms: structured and qualified requests

Social channels

  • Facebook/Instagram: messaging and public comments
  • Twitter/X: often used for public complaints
  • WhatsApp: a rapidly growing channel, especially internationally

Self-service channels

  • FAQ/Knowledge Base
  • Customer portal
  • Community forums

Why omnichannel has become essential

Customers are asking for it

73% of customers use multiple channels during their purchasing journey. They expect a seamless experience across all these touchpoints.

The frustration of "re-explaining"

According to a Salesforce study, 76% of customers expect all agents to be aware of their history. Having to repeat their problem is one of the main sources of frustration.

Competitive advantage

Companies with a strong omnichannel strategy retain an average of 89% of their customers, compared to 33% for those with a weak strategy.

The benefits of omnichannel

For the customer

  • No need to repeat its history
  • Freedom to choose your preferred channel
  • Consistent and personalized experience
  • Faster resolution

For the company

  • Actionable 360° customer view
  • Greater satisfaction and loyalty
  • Unified data for analysis
  • Resource optimization

For agents

  • Complete context from the moment of admission
  • Fewer redundant questions
  • More efficient work

The challenges of omnichannel retailing

Technical challenge: integration

Connecting all channels to a single platform requires robust integrations. Data must flow in real time.

Organizational challenge: silos

If the email team doesn't talk to the phone team, omnichannel won't work. It's as much a human project as it is a technical one.

Consistency challenge

The tone, responses, and processes must be consistent across all channels. This requires documentation and training.

How to implement an omnichannel strategy

1. Assess your current situation

  • Which channels are active?
  • Are they integrated or siloed?
  • What is the typical customer journey?
  • Where are the sticking points?

2. Centralize customer data

A CRM or customer service platform that aggregates all interactions is essential. Agents must be able to view the complete history with a single click.

3. Choose a unified platform

Modern tools (Zendesk, Freshdesk, Intercom, etc.) allow you to manage all channels from a single interface.

4. Train your teams

Agents must be able to navigate between channels and understand the specificities of each while maintaining consistency.

5. Automate intelligently

AI can route requests to the right channel/agent, suggest consistent responses, and maintain context across channels.

Klark integrates seamlessly with leading platforms to bring a layer of intelligence to all your channels, with consistent, contextualized responses.

6. Measure by channel AND overall

Track KPIs by channel to identify specific characteristics, but also globally to gain a complete view of the customer journey.

Omnichannel and KPIs

Omnichannel impacts several key indicators:

KPIImpact of omnichannel
CSAT↑ Smooth experience = increased satisfaction
FCR↑ Full context = better resolution
AHT↓ Less time spent gathering context
CES↓ Less effort for the customer

Mistakes to avoid

Mistake #1: Adding channels without integrating them

Opening a WhatsApp channel without connecting it to your CRM creates a new silo. Integrate before activating.

Mistake #2: Neglecting training

An omnichannel tool that is poorly used is worthless. Invest in training your teams.

Mistake #3: Forgetting the mobile

A large part of interactions take place on mobile devices. Your experience must be perfect on this medium.

Mistake #4: Ignoring customer preferences

Some customers prefer email, others prefer the phone. Respect their preferences rather than forcing a channel.

Mistake #5: No unified customer view

Without centralized history, omnichannel doesn't really exist. It's the foundation of everything.

Frequently Asked Questions

Is it necessary to be present on all channels?

No. It's better to excel on a few well-integrated channels than to be mediocre everywhere. Choose according to your target audience.

What is the cost of an omnichannel strategy?

Varies depending on complexity. SaaS platforms allow you to get started for a few hundred euros per month.

How long does it take to set up omnichannel?

From a few weeks (basic integration) to several months (complete transformation with change management).

Is omnichannel suitable for small businesses?

Yes! Modern tools are accessible. An SME can have an omnichannel approach with 2-3 well-integrated channels.

Conclusion

Omnichannel is not a technological luxury; it's what your customers expect. A seamless, consistent experience where they never have to repeat their story.

The keys to a successful omnichannel strategy:

  • Centralize customer data
  • Integrate before adding new channels
  • Train your teams to be consistent
  • Automate to maintain context
  • Measure the overall experience, not just by channel
