CRM Sync Strategy: Bidirectional Data Flow & Field Mapping Best Practices

How do I sync intent data to my CRM?

Quick Answer: Set up a bidirectional CRM integration that reads account ownership from your CRM while pushing behavioral and intent signals back.

Map fields strategically using "fill if empty" for enrichment data (job titles, company size) and "always update" for dynamic signals (website visits, engagement scores).
Filter syncs to ICP-qualified visitors only to prevent CRM bloat.

Quick Answer: Best CRM Sync Strategy by Use Case

Best for HubSpot marketing teams: Native HubSpot integration with auto-created properties and hourly batch sync for visit data. See Warmly's HubSpot integration.

Best for Salesforce enterprise teams: Managed package installation for activity timeline tracking and custom object support. Requires 2-3 days setup but provides deeper visibility.

Best for real-time sales alerts: Continuous sync with Slack/Teams notifications triggered when ICP visitors hit high-intent pages like pricing or demo requests. Learn about real-time alerts.

Best for preventing data conflicts: Pull territory and ownership FROM your CRM, never push TO it. Let your CRM routing rules remain the source of truth.

Best for enrichment without overwrites: Use "fill if empty" sync logic for firmographic data so validated rep corrections don't get overwritten by automated enrichment.

Best for multi-system setups: Hub-and-spoke model where Warmly syncs to HubSpot, then HubSpot syncs to Salesforce. Prevents circular syncing and duplicate creation.

Introduction

One of the most common questions B2B revenue teams ask is: "How do I get intent data into my CRM without creating a data mess?"

After analyzing 141+ customer implementation calls, the answer comes down to three things: thoughtful field mapping, smart sync logic, and aggressive filtering. Teams across SaaS, security, and enterprise tech have figured this out. They're syncing thousands of contacts monthly without overwriting validated data or overwhelming sales with noise.

This guide breaks down the exact strategies that work, pulled directly from real implementation conversations.

1. One-Time Sync vs. Continuous Sync: When to Use Each

The Core Question

During a recent implementation with a B2B technology company, their Senior Manager of Growth Marketing Operations asked: "Should I set this up to sync to HubSpot once, or have it continuously running?"

Every RevOps team faces this question. The answer depends on your use case.

One-Time Sync: Best For

Use one-time sync when you're:

Testing new segments before automating. One customer tested their ICP segmentation by syncing visitors who viewed pricing pages, validated the data quality, then enabled continuous sync.
Backfilling historical data. Initial setup and data migration scenarios.
Running specific campaigns. Syncing a webinar attendee list or event follow-up segment.
Exporting to sales engagement tools. Pushing lists to Outreach or Salesloft for specific cadences.

Continuous Sync: Best For

Use continuous sync when you need:

Real-time lead routing. High-intent visitors who should hit a rep's queue immediately.
Behavioral score updates. Page views, time on site, and session counts that change constantly.
Job change alerts. When someone joins a target account, update their contact record right away.
Multi-touch intent aggregation. Building a complete picture of engagement over time.

Real Example: One mid-market SaaS company's Director of Marketing Operations configured continuous sync specifically for accounts in tiers 1-3 who visited high-value pages. SDRs received Slack alerts within minutes of qualification.

The Hybrid Approach (What Most Teams Do)

Start with a one-time sync to validate data quality. Enable continuous sync for ICP segments only. Use filters to prevent CRM bloat.

One VP of Revenue Operations put it this way:

"Once it's synced, it's synced. You might have triggers that say 'after a period of time, or if this record changes, sync it again.' But you're not just blindly syncing everything."

2. Field Mapping Strategies for HubSpot and Salesforce

The Most Common Mistake

Mapping every available field "just in case."

During one legal tech company's implementation, their team initially tried to map 30+ fields. After experiencing sync delays and CRM clutter, they narrowed it down to 8 essential fields. Sync performance improved by 300%.

Essential Field Categories

Behavioral Signals (Always Update)
Field Purpose Sync Logic
Last Visit Date Regency Signal Always Update
Total Time on Site Engagement Depth Always Update
Session Count (30d) Visit frequency Always Update
High-Intent Page Views Pricing, demo, case studies Always Update
UTM Parameters Campaign attribution Always Update

Enrichment Data (Fill If Empty)
Field Purpose Sync Logic
Job Title Contact identification Fill If Empty
Company Size Firmographic qualification Fill If Empty
Industry Segmentation Fill If Empty
LinkedIn Profile URL Sales research Fill If Empty

Intent Signals (Always Update)

Field	Purpose	Fill If Empty
Bombora Topic Surge Scores	Third-party intent	Always Update
Buying Committee Members	Account intelligence	Always Update
Persona Classification	Lead routing	Always Update

HubSpot-Specific Field Mapping

Recommended Custom Properties:

Contact Properties

- warmly_persona (dropdown)
- warmly_engagement_score (number)
- warmly_last_visit_date (date)
- warmly_high_intent_pages (text)
- warmly_session_count_30d (number)

Company Properties

- warmly_audience (text)
- warmly_bombora_topics (text)
- warmly_company_visits_30d (number)
- warmly_total_identified_visitors (number)
- warmly_intent_score (number)

Real Implementation Example: One device management company's Head of GTM Operations mapped only 6 custom properties:

Warmly Audience - Triggered lifecycle stage changes
Persona - Routed leads to specialized SDRs
Active Time on Site - Minimum 30 seconds to qualify
Last Seen Date - Recency scoring
Confidence Score - Only synced contacts >70% confidence
ICP Fit - Prevented non-ICP from entering CRM

Result: 47% reduction in junk leads entering their CRM, 2.3x increase in SDR qualification rates.

Salesforce-Specific Field Mapping

Minimum Required Fields for Lead Creation:

Based on enterprise implementations, Salesforce requires:

First Name
Last Name
Email
Company Name
State/Region
Country
Industry

Custom Fields Pattern:

Lead/Contact Fields

- Warmly_Engagement_Score__c (Number)
- Warmly_Last_Visit__c (DateTime)
- Warmly_Intent_Topics__c (Long Text Area)
- Warmly_ICP_Tier__c (Picklist: Tier 1, Tier 2, Tier 3, Not ICP)

Account Fields

- Warmly_Total_Visitors__c (Number)
- Warmly_Buying_Committee_Count__c (Number)
- Warmly_Account_Intent_Score__c (Number)

Managed Package vs. API Integration

Factor	Managed Package	API Integration
Setup Time	2-3 days	1-2 hours
Activity Timeline	Full tracking	Limited
Custom Objects	Supported	Not supported
Best For	Enterprise teams	(<50 reps)
Complexity	Higher	Lower

Enterprise Requirement "The Salesforce managed package is non-negotiable for us because we need object-level tracking, not just field updates."

3. Fill If Empty vs. Always Update: The Critical Decision

Why This Matters

One RevOps team voiced a common fear: "We've spent months manually correcting firmographic data in Salesforce. Will Warmly overwrite our validated data with lower-quality enrichment?"

The answer lies in sync logic configuration.

Fill If Empty: Use for Static Enrichment

Definition: Only populate the field if it's currently null/empty in your CRM.

Best For: - Job titles (unless tracking job changes) - Company size/employee count - Industry classification - Company headquarters location

Why: If a sales rep manually corrects a contact's title from "Engineer" to "VP of Engineering" based on a discovery call, you don't want automated enrichment overwriting that validated data.

Always Update: Use for Dynamic Behavioral Data

Definition: Update the field every time new data is available.

Best For: - Last visit date/time - Total page views - Engagement scores - Session counts - Intent topic surge scores

Why: Behavioral data is time-sensitive. Yesterday's pricing page visit should override "Last Visit: 30 days ago" in your CRM.

The Decision Matrix

Field Type	Sync Logic	Why
Job Title	Fill If Empty	Reps manually correct during discovery
Company Size	Fill If Empty	Static unless tracking growth
Last Visit Date	Always Update	Time-sensitive behavioral signal
Engagement Score	Always Update	Changes with each visit
Intent Topics	Always Update	Bombora scores change weekly
Territory/Owner	Read Only	CRM routing rules should control
Lifecycle Stage	Conditional	Only progress forward, never backward
Lead Source	Fill If Empty	First-touch attribution should be immutable

Territory Assignment Exception

Multi-Product Routing Complexity: Some companies route leads by product line across multiple business units.

Their Sync Rule: "Pull territory assignment FROM Salesforce, never push TO Salesforce. Let Salesforce routing rules handle assignment."

This prevented accidental overwriting of carefully configured territory logic.

4. Managing Custom Properties and Objects

Do I Create the Field First?

Common Question: "Do I create the field first, then map it? Or does Warmly auto-create it?"

Answer: It depends on your CRM.

HubSpot: Auto-Creation Supported

For HubSpot, properties can be auto-created during initial sync if they don't exist. But best practice is to pre-create them with specific formats:

Property name (e.g., warmly_engagement_score)
Field type (Single-line text, Number, Date, Dropdown)
Group assignment (e.g., "Warmly Data")
Description for sales team visibility

Salesforce: Manual Creation Required

Salesforce requires custom fields to exist before mapping.

Recommended Process:

Create custom fields in Salesforce sandbox
Test sync with 10 records
Validate data quality and formatting
Create fields in production
Map in Warmly settings
Enable sync for qualified segments

Multi-System Architecture

Common Challenge: "We use both HubSpot and Salesforce. Anything that goes into HubSpot also goes into Salesforce."

Recommended: Hub-and-Spoke Model

Warmly → HubSpot (marketing automation)

                      ↓

                 HubSpot → Salesforce (qualified leads only)

This maintains a single source of truth and prevents duplicate syncing.

Not Recommended: Parallel sync to both systems (risk of circular syncing and conflicts).

5. Avoiding Data Conflicts and Duplicates

The Duplicate Prevention Strategy

Key Lesson: "To minimize duplicate companies, we limited our Change-Jobs play to existing CRM companies only. We don't create net-new accounts from job change alerts."

Common Conflict Scenarios

Email Mismatch Duplicates

Problem: Warmly identified [email protected], Salesforce had [email protected]. Result: Duplicate created.

Solution:

Enable fuzzy matching by domain + first/last name
Set minimum confidence threshold (70%+)
Use LinkedIn profile URL as secondary deduplication key

Territory Routing Conflicts

Problem: Multiple reps claimed the same account. Warmly synced to the first matched owner.

Solution:

Pull territory assignment FROM CRM, don't push TO CRM
Use account-level routing rules in Salesforce
Let CRM be the source of truth for ownership

Lifecycle Stage Conflicts

Enterprise Workflow: "Leads enter HubSpot first, qualify there with lead scoring, then sync to Salesforce only after reaching MQL threshold."

Best Practice:

Only sync leads that meet minimum qualification threshold
Never push leads backward in lifecycle stage
Use separate syncs for different lifecycle stages

The Confidence Score Filter

Best Practice from 30+ Implementations: Only sync contacts with confidence score >70%.

Testing Results:

50% threshold: 40% false positives
70% threshold: 12% false positives
85% threshold: 3% false positives, but missed 30% of valid leads

Optimal: 70% for most B2B companies.

Segment Before Sync

Effective Filtering Strategy:

Company size: 50-5,000 employees
Industry: SaaS, Technology, Professional Services
Exclude: Customers, closed-lost (last 6 months), competitors
Include: Active in the last 30 days + viewed pricing/demo page

Result: 73% reduction in non-qualified leads syncing to CRM.

6. Bidirectional Sync Architecture Explained

What "Bidirectional" Actually Means

Common Confusion: "Is it a two-way sync?"

Clarification:

Read FROM CRM (Warmly pulls in):

Account ownership - Lifecycle stages
Custom fields (ICP tier, ABM list membership)
Territory assignment
Opportunity stage

Write TO CRM (Warmly pushes out):

Website visit data
Engagement scores
Intent signals
Chat transcripts
Enriched contact/company data

Real-Time vs. Batch Sync

Common Question: "Is it real-time or batch?"

Real-Time (Push Immediately):

Chat messages
Form submissions
High-intent page views (pricing, demo request)
Qualified visitor alerts

Batch Sync (Every 60 minutes):

Engagement score updates
Session count aggregations
Intent topic updates
Firmographic enrichment

Why the Hybrid? Real-time for actionable signals needing immediate rep response. Batch for aggregate data that doesn't require instant updates.

Initial Sync Timeline

Typical Mid-Market Implementation:

CRM size: 47,000 contacts, 12,000 accounts
Initial sync time: 1 hour 15 minutes
Ongoing sync: Every 60 minutes (incremental)

7. Intent Data Sync Specifics

Bombora Integration Strategy

Example Setup: Track up to 12 Bombora keywords: revenue operations, sales enablement, conversation intelligence, sales automation, lead routing, CRM optimization.

Field Structure:

bombora_topics_surging (text): "Revenue Operations (75), Sales Enablement (68)"

bombora_highest_topic (text): "CRM Optimization"

bombora_highest_score (number): 82

bomborasurgedate (date): 2025-01-15

Sync Strategy:

Always Update (scores change weekly)
Trigger alerts when score >70
Create CRM workflow: Score >70 + pricing page visit = hot lead

Learn about Bombora integration

Website Behavioral Signals

Time-on-Site Thresholds (Based on 40+ Implementations):

Duration	Intent Level
<30 seconds	Bounce (don't sync)
30-120 seconds	Low intent
2-5 minutes	Medium intent
5+ minutes	High intent

High-Intent Pages (Always Sync):

/pricing
/demo
/contact-sales
/vs/[competitor]
/case-studies/[industry]

Effective Logic: "If CRM company equals accounts tier 1-3, first-party signals, and they visit high-value pages → sync immediately + Slack alert to account owner"

UTM Parameter Capture

Critical for Attribution:

crm_campaign_source: "linkedin" 
crm_campaign_medium: "paid" 
crm_campaign_name: "Q1_Product_Launch"

Sync Logic:

First Touch: Fill If Empty (never overwrite)
Last Touch: Always Update
All Touches: Append to multi-touch field

Intent Score Aggregation

Multi-Signal Scoring Formula:

Intent Score = (Bombora Surge × 0.30) 
             + (Website Visits × 0.25) 
             + (High-Intent Pages × 0.25) 
             + (Engagement Score × 0.15) 
             + (LinkedIn Activity × 0.05)

Sync Strategy:

Recalculate hourly
Push to CRM when score changes >10 points
Trigger workflows at thresholds (50, 70, 90)

FAQs

"How do I sync intent data to my CRM?"

Set up a bidirectional integration with your HubSpot or Salesforce instance. Map behavioral and intent fields to custom properties, configure orchestrations to sync qualified visitors based on ICP criteria, and use "fill if empty" for enrichment data and "always update" for behavioral signals.

See the full integration guide

"What's the difference between one-time sync and continuous sync?"

One-time sync pushes a specific list once, best for testing segments or campaign exports. Continuous sync updates automatically (usually hourly), best for real-time lead routing and behavioral tracking. Most teams use a hybrid: one-time to validate, then continuous for ICP segments only.

"Should I use fill if empty or always update for CRM fields?"

Use "fill if empty" for static enrichment data like job titles and company size (so rep corrections don't get overwritten). Use "always update" for dynamic behavioral signals like last visit date, engagement scores, and intent topics (since these change constantly and should always reflect the latest state).

"How do I prevent CRM duplicates when syncing intent data?"

Three strategies: (1) Set a 70%+ confidence score threshold to filter low-quality matches, (2) Enable fuzzy matching by domain + name for email variations, (3) Limit job-change syncs to existing CRM companies only rather than creating net-new accounts.

"Will syncing intent data overwrite my validated CRM data?"

Not if configured correctly. Use "fill if empty" sync logic for firmographic fields like job titles. This ensures automated enrichment only populates empty fields and never overwrites data that reps have manually corrected based on discovery calls.

"How long does the initial CRM sync take?"

Depends on CRM size. For a typical mid-market company (47,000 contacts, 12,000 accounts), initial sync takes about 1 hour 15 minutes. After that, incremental syncs run every 60 minutes and complete in minutes.

"Can I sync to both HubSpot and Salesforce at the same time?"

Yes, but use the hub-and-spoke model: Warmly syncs to HubSpot, then HubSpot syncs qualified leads to Salesforce. This maintains a single source of truth and prevents circular syncing that can cause duplicates and conflicts.

"What fields should I sync to my CRM from intent data?"

At minimum: Last Visit Date, Engagement Score, Session Count, High-Intent Page Views, and ICP Tier. For intent data specifically: Bombora Topics, Intent Score, and Surge Date. For enrichment: Job Title, Company Size, and LinkedIn URL (all using fill if empty).

Key Takeaways

Start with one-time sync to validate data quality before enabling continuous sync
Use "Fill If Empty" for enrichment (titles, firmographics) and "Always Update" for behavioral signals
Set a 70% confidence threshold to balance coverage and accuracy
Segment before syncing to prevent CRM bloat
Let CRM handle territory routing by pulling ownership rather than pushing it
Sync intent signals separately from enrichment for better workflow triggers
Monitor duplicate creation rate weekly and adjust fuzzy matching logic
