If you’ve ever tried to analyse your customer data and ended up feeling like you were looking at five different, conflicting stories — you’re not alone. Most growing businesses in Hong Kong and across Asia deal with the same challenge every day.
Sales has one version of customer data.
Marketing has another.
Customer service sees something else.
The ecommerce team looks at a separate set.
Meanwhile, the loyalty system follows its own logic.
And none of it matches.
This is the reality of data silos — one of the biggest obstacles to delivering a seamless customer experience. The solution is a Single Customer View (SCV), also known as a Customer 360. Let’s break it down in a simple way and walk through how your business can move from scattered data to a unified customer view that actually drives growth.
Why Data Silos Are a Serious Problem
At first, data silos may not appear harmful. Your CRM works. Your email platform works. Your POS works. Your website analytics work. But the issue is that none of these systems communicate with each other.
The result is a list of problems that stack up quickly: duplicated customer records, inconsistent purchase history, incorrect segments, poorly targeted campaigns, confusing customer journeys, wasted ad spend, inaccurate reporting, and slower decision-making. If your team constantly asks, “Which data is correct?”, “Why is marketing’s number different from sales?”, or “Why can’t we personalise this campaign?”, your business is dealing with silos — and they’re costing you real money.
What Is a Single Customer View?
A Single Customer View (SCV) is a unified, accurate, real-time profile of each customer. Instead of storing scattered information in different platforms, an SCV connects all touchpoints into one identity and one timeline.
This includes data from:
- website visits
- purchase behaviour
- loyalty programme activity
- SMS and email engagement
- WhatsApp/WeChat interactions
- customer service tickets
- POS transactions
- mobile app activity
- campaign responses
- offline store visits
Once unified, every team sees the same truth — one complete customer view. This is why Customer Data Platforms (CDPs) play such a critical role in modern marketing ecosystems.
Step-by-Step Guide: Moving From Data Silos to a Customer 360
Here is the practical process most companies follow.
Step 1: Identify All Data Sources
Start by mapping every system that stores customer data, including:
CRM, POS, ecommerce backend, email/SMS/WhatsApp/WeChat tools, loyalty programs, customer service platforms, app analytics, payment gateways, social media, and offline store systems.
Most companies are surprised to discover 10–20 separate sources of customer data. This step alone brings clarity to how fragmented the customer journey really is.
Step 2: Clean & Standardise the Data
Before merging, you must resolve inconsistencies such as duplicated profiles, missing information, incorrect phone numbers, different naming formats, mismatched email–phone combinations, or duplicate loyalty IDs. Good data hygiene ensures the SCV you build later is reliable.
Step 3: Connect the Systems Through Integrations or APIs
This is the technical foundation. Using integrations, middleware, or a CDP, you connect all systems so data flows into one central platform. This allows real-time synchronisation between:
- online and offline purchases
- CRM and marketing channels
- loyalty and ecommerce
- app and website behaviour
- WeChat/WhatsApp interactions
- customer service history
No more exporting files manually or copying data from one system to another.
Step 4: Unify Customer Identity
Each system identifies customers differently — email in one, phone number in another, loyalty ID in another, and device ID somewhere else. A CDP uses identity resolution to merge all these identifiers into a single, accurate customer profile.
One person becomes one ID with one complete timeline.
Step 5: Build Real-Time Customer Profiles
Once identity is resolved, the system creates dynamic customer profiles that update in real time. These profiles include:
- demographics
- purchase history
- browsing behaviour
- loyalty tier and spend
- coupon usage
- engagement scores
- preferred channels
- lifetime value (CLV)
- churn predictions
- recommended products or services
This becomes your Single Source of Truth across the organisation.
Step 6: Activate the Data Across All Teams
This is where an SCV delivers its true value. Once you have clean, unified data, you can:
✔ personalise campaigns automatically
✔ run behaviour-based automation
✔ identify high-value customers easily
✔ send real-time triggered messages
✔ improve loyalty programme relevance
✔ retarget more accurately
✔ shorten the sales cycle
✔ respond faster in customer service
✔ build more accurate dashboards
Everything becomes more efficient, more personalised, and more aligned with customer needs.
