What is data management?

Data management is the organised approach to collecting, storing, maintaining, and using your business information effectively.

It’s about making sure your data is accurate, accessible, secure, and valuable across your entire organisation.

For B2B specifically, effective data management:

• Creates a single source of truth for customer and prospect information.
• Establishes governance frameworks for data quality and compliance.
• Implements technologies that make data accessible to the right people.
• Builds business processes to keep information current and accurate.
• Develops methods to transform raw data into actionable insights.
• Ensures security and regulatory compliance across all data activities.

Without proper management, key business data degrades at 30% annually, directly undermining your revenue efforts.

What are the key components of a data management strategy?

A comprehensive B2B data management strategy encompasses:

1. Data collection: Methods for gathering information from primary and third-party sources.
2. Data storage: Database architecture and cloud vs. on-premises decisions.
3. Data cleansing: Processes to identify and correct inaccuracies.
4. Data enrichment: Adding value through third-party intelligence.
5. Data integration: Connecting information across your tech stack.
6. Data governance: Policies for handling information responsibly.
7. Data analysis: Converting raw data into actionable insights.
8. Data security: Protocols to safeguard sensitive information.

While many organisations focus primarily on collection and storage, the most successful revenue teams invest equally in cleansing, enrichment, and integration.

Why does data management matter for B2B revenue teams?

Here’s how effective data management affects each revenue function in your organisation:

For sales teams

Sales reps waste an average of 22.75 days each year on inaccurate data.

With robust data management, sales teams can eliminate data inconsistencies, ensuring accurate lead information, precise contact details, and comprehensive customer insights.

This translates directly to faster deal cycles, more targeted outreach, and improved pipeline forecasting.

For marketing teams

Data management enables precision marketing i.e. precision targeting and personalised communication.

Without clean, integrated data, marketing efforts become scattershot. You end up wasting resources on irrelevant messaging and poorly targeted campaigns.

Comprehensive data management allows marketers to create detailed customer profiles, accurately track buyer journeys, and develop hyper-personalised marketing strategies that resonate with specific audience segments.

For customer success teams

Customer success teams rely on data to transform reactive support into proactive relationship management.

Fragmented data means missed opportunities, inconsistent customer experiences, and reduced retention potential. 

Proper data management creates a 360-degree view of each customer, tracking complete interaction histories, identifying potential churn risks, and enabling personalised engagement strategies.

For RevOps teams

Without strong data management, RevOps teams struggle with inefficiencies, misalignment, and poor forecasting.

Clean, unified data helps revenue operations analyse performance, identify trends, and make data-driven decisions that optimise revenue growth.

What are the best practices for B2B data management?

Follow these proven approaches to maximise the value of your B2B data:

1. Establish clear data governance

Data governance forms the foundation of effective management. It defines who owns, manages, and can access different information types within your organisation.

Define data ownership

Assign specific accountability for different data categories (contacts, accounts, opportunities) to appropriate teams or individuals.

This prevents the “everyone’s responsibility means it’s no one’s responsibility” problem.

Implementation tip

Create a RACI matrix (Responsible, Accountable, Consulted, Informed) for each data type, clearly documenting who makes decisions about field definitions, required values, and quality thresholds.

Create standardised processes

Develop consistent procedures for data entry, updates, and maintenance across departments.

When everyone follows the same protocols, data consistency improves dramatically.

Implementation tip

Document step-by-step workflows for common data actions (adding contacts, updating company information, recording interactions) with screenshots and examples of properly formatted data.

Document data definitions

Establish a shared understanding of each field’s meaning, acceptable values, and how the information will be used.

This eliminates confusion and improves reporting accuracy.

Implementation tip

Create a searchable data dictionary that includes:

• Field definitions.
• Format requirements.
• Example values.
• Business context for why each data point matters.

2. Implement regular data cleansing

Data quality decays naturally over time.

Follow these steps to ensure your data remains sound:

Audit your database quarterly

Schedule regular reviews to identify errors, outdated information, and gaps in critical fields.

This prevents the gradual erosion of data quality that undermines your revenue efforts.

Implementation tip

Create data quality scorecards for key data objects (accounts, contacts, opportunities) with metrics like completeness, accuracy, and recency that teams can track over time.

Remove duplicates

Duplicate records skew analytics, waste marketing resources, and create confusion about customer history.

Implement both automated and manual deduplication processes.

Implementation tip

To identify potential duplicates, use fuzzy matching rules based on email domains, company names, and contact information.

Then, have data stewards review and merge records appropriately.

Update contact details proactively

Don’t wait for bounced emails or failed calls to identify outdated information.

Implement data management systems (like Cognism!) to refresh contact data automatically.

Implementation tip

Manage your data effectively with Cognism Enrich! It’s the ultimate solution for keeping your CRM data fresh and reliable, supporting:

• Instant enrichment (updating your CRM in real-time).
• Scheduled enrichment (refreshes your CRM on a regular cadence).
• On-demand CSV enrichment (upload your CSV and Cognism will fill in the missing info).

3. Enrich with third-party intelligence

First-party data tells only part of the customer story. External enrichment provides crucial context for effective targeting and engagement.

Supplement first-party data

Combine your internally collected information with validated third-party data to create complete customer profiles.

This provides a more comprehensive view of each account.

Implementation tip

Prioritise enrichment fields based on your ideal customer profile criteria.

Focus first on information that directly impacts lead qualification and segmentation.

Add verified contact information

Standard business contact details (switchboard numbers, generic emails) create barriers between your team and decision-makers.

Invest in accurate direct dials, mobile numbers, and personal emails.

Implementation tip

Check out Cognism’s Diamond Data®, a unique data asset comprising phone-verified mobile numbers.

These numbers guarantee you’ll reach up to 87% of your sales list.

Incorporate intent signals

Traditional firmographic data shows who might buy, but intent data reveals who’s actively looking to buy now. Combine both for maximum impact.

Implementation tip

Cognism’s intent data (powered by Bombora) is available in our Elevate pricing package. For more information, visit our pricing page.

4. Centralise your data architecture

Fragmented data creates contradictory views of customer reality. A centralised architecture establishes a single version of truth.

Establish your CRM as the system of record

Designate one platform as the authoritative source for customer information. Your goal is to eliminate conflicts between systems.

Implementation tip

Document which fields originate in which systems. Ensure you have clear rules for which platform takes precedence when conflicts arise.

Connect key platforms

Ensure marketing automation, sales engagement, customer success, and financial systems share relevant customer data bi-directionally.

Implementation tip

Create smooth data flows

Implement real-time or near-real-time synchronisation between systems. You want your teams to work with the most current information.

Implementation tip

Audit sync frequencies and error logs monthly.

Identify and resolve integration issues before they impact revenue operations.

5. Prioritise compliance and security

Non-compliant data usage creates significant legal and reputational risks for B2B organisations.

Stay up-to-date with regulatory requirements

The GDPR, CCPA, and country-specific telemarketing regulations create a complex regulatory compliance landscape.

Establish management processes to keep pace with requirements.

Implementation tip

Cognism is a GDPR and CCPA-compliant B2B data provider. It maintains compliance in the following ways:

• It adheres to a stringent data verification process.
• It ensures all its data is legally sourced and of the utmost quality.
• It’s regulated by the ICO and provides users with a notified database.
• It scrubs mobile numbers against Do-Not-Call lists in a record 13 countries: the UK, USA, Australia, Canada, New Zealand, Belgium, Croatia, France, Germany, Ireland, Portugal, Spain, and Sweden.

Establish security protocols

Create appropriate access controls, encryption standards, and handling procedures for sensitive information.

Implementation tip

Implement role-based access controls that limit data visibility based on business need, with special protection for personally identifiable information.

6. Focus on data usability

Even perfectly accurate data provides no value if teams can’t easily access and apply it.

Make data accessible

Create intuitive interfaces and reports that put relevant information at users’ fingertips without requiring technical expertise.

Implementation tip

Build role-specific dashboards and views that highlight the most relevant data for each team member’s function. Try to limit information overload!

Provide contextual information

Raw data points become valuable when teams understand what they mean and how to use them.

Implementation tip

Add field-level help text, tooltips, and usage examples to your CRM and other platforms.

This will help to guide proper interpretation.

Create actionable signals

Transform data into clear next steps for sales and marketing teams through alerts, tasks, and prioritisation frameworks.

Implementation tip

Implement scoring models that combine multiple data points into simple prioritisation signals, with automated task creation when high-value triggers occur.

What are the common challenges and solutions in B2B data management?

Even with the right tools and intentions, B2B organisations face significant data management challenges.

Here’s how to overcome them:

Challenge 1: Data decay

B2B data decays at 22.5% annually as people change roles, companies, and contact details, making yesterday’s perfect contact list today’s collection of bounced emails. 

The solution?

Invest in continuous verification rather than one-time purchases. 

Partner with data enrichment providers like Cognism that automatically refresh your data.

Implement regular enrichment cycles for high-value segments, establish quality metrics with automated alerts, and create simple mechanisms for sales teams to flag outdated information during their daily outreach.

Challenge 2: Siloed systems

86% of senior executives agree that eliminating organisational silos is critical to expanding the use of data and analytics in decision-making.

When your marketing, sales and customer success platforms don’t communicate, your entire revenue operation suffers.

To avoid this, establish your CRM as the central source of truth with clear ownership hierarchies.

Connect platforms through integration tools like Segment or Zapier, and ensure changes in one system automatically update across your entire tech stack.

Challenge 3: Compliance complexity

The global patchwork of data regulations creates significant risk. 

The GDPR, CCPA, and country-specific rules each have unique requirements for consent, retention, and transparency, with penalties reaching 4% of global revenue. 

Protect your organisation by partnering with compliance-focused data providers who handle verification as part of their service.

Document all consent with detailed timestamps and communication preferences. 

Create SLAs for handling data subject requests with clear responsibility assignments and response timeframes.

Challenge 4: Adoption resistance

Even perfect systems fail when teams resist using them. 

Sales representatives often view data management as administrative overhead, leading to incomplete updates, neglected spreadsheets, and inconsistent practices.

Overcome this resistance by demonstrating how quality data directly drives sales KPIs.

Show the connection between clean data and better sales, including higher connect rates, faster deals, and improved commissions. 

Integrate data management into existing workflows and recognise team members who maintain high standards.

Challenge 5: Attribution difficulties

Marketing investments become guesswork when you can’t track prospects across their buying journey. 

Which activities truly influence deals? Without proper attribution, early-stage marketing gets undervalued while last-touch interactions receive disproportionate credit.

Start by implementing consistent tracking parameters across all campaigns and platforms. 

Connect anonymous website visits to accounts through IP matching, then link them to individual contacts as they identify themselves. 

Build attribution models that distribute credit across touchpoints rather than assigning all value to a single interaction. 

Boost your revenue with better data

Poor data management isn’t just an inconvenience, it’s a direct threat to your revenue goals. Sales teams can’t connect with prospects, marketing campaigns miss their targets, and leadership lacks the insights needed for strategic decisions.

The path forward is clear:

Implement effective data management practices and partner with providers like Cognism that deliver accurate, compliant, and actionable B2B data.

Companies that prioritise data management achieve:

• 3x more live conversations with prospects.
• 70% more efficient prospecting processes.
• Measurable improvements in conversion rates at every funnel stage.
• Significantly higher ROI on marketing and sales investments.

Don’t let bad data hold your revenue teams back. Experience the difference that phone-verified, compliant B2B data makes.
