The Problem with One-Way Sync

Traditional integrations often move data in a single direction, such as pushing leads from HubSpot into Salesforce. This approach leaves gaps: updates made in Salesforce don’t flow back to HubSpot, and teams end up with conflicting records, duplicate contacts, and manual reconciliation work. As a result, sales and marketing teams operate on different versions of the truth, undermining both customer experience and operational efficiency.

The Value of Real-Time, Two-Way Synchronization

Bi-directional sync means that any change—whether it’s a new deal in HubSpot, an updated contact in Salesforce, or a custom field change in NetSuite—automatically propagates to all connected systems. This ensures:

• No more manual data entry or reconciliation
• Consistent, up-to-date information for every team
• Faster response times for sales and support
• Reduced risk of errors and compliance issues

For example, a sales rep updates a customer’s phone number in Salesforce. With bi-directional sync, that change appears instantly in HubSpot, NetSuite, and any other connected system—no extra steps required.

Beyond Basic Integration: Operational-Grade Data Consistency

Stacksync is designed for organizations that need more than just basic data movement. Its real-time, bi-directional sync engine ensures that every change—no matter where it originates—flows instantly across all systems. Unlike batch-based ETL tools or one-way connectors, Stacksync’s architecture supports:

• Sub-second propagation of updates between HubSpot, Salesforce, NetSuite, and databases
• Field-level change detection, so only the relevant data moves
• Automatic conflict resolution, preventing data overwrites and duplicates
• Support for both standard and custom objects, including complex associations

Technical Deep Dive: How It Works

Stacksync uses a combination of Change Data Capture (CDC), event-driven processing, and a robust connector framework to achieve real-time sync. Here’s a simplified workflow:

1. Connect Systems: Use OAuth or secure credentials to link HubSpot, Salesforce, NetSuite, and your databases.
2. Map Fields: Stacksync auto-detects schemas and suggests mappings, but you can customize as needed.
3. Set Sync Rules: Define which objects and fields to sync, and set conflict resolution preferences.
4. Activate Sync: Changes in any system trigger instant updates everywhere else, with full audit trails and error handling.

Technical specification: Stacksync can process up to 60,000 HubSpot records per minute, with latency measured in milliseconds for most operations.

1. CRM and ERP Integration

Many organizations use HubSpot for marketing and Salesforce or NetSuite for sales and finance. Stacksync enables seamless, two-way sync of contacts, deals, and custom objects, ensuring that every department works from the same data set.

• Sync customer records between HubSpot and Salesforce, including custom fields and associations
• Propagate deal status changes from NetSuite to HubSpot for real-time marketing follow-up
• Maintain referential integrity across all systems, even with complex data models

2. Database Synchronization

For companies that rely on operational databases (like PostgreSQL or MySQL), Stacksync allows direct, bi-directional sync between HubSpot and your database. This means developers can work with familiar SQL tools, while business teams see updates reflected instantly in HubSpot.

3. Workflow Automation

Stacksync’s workflow engine lets you trigger automated actions based on data changes. For example:

• Send a Slack alert when a high-value deal closes in HubSpot
• Update inventory records in NetSuite when a new order is logged in HubSpot
• Enrich CRM data with external API calls, all within a single workflow

4. Data Quality and Compliance

With field-level change detection and robust error handling, Stacksync helps maintain data quality and supports compliance requirements like GDPR and HIPAA. All data is encrypted in transit and at rest, and no persistent storage is used.

Quick Setup, No Heavy Lifting

Stacksync’s no-code interface and 200+ pre-built connectors mean you can connect HubSpot to Salesforce, NetSuite, databases, and more in minutes. The platform automatically handles API authentication, schema mapping, and error recovery.

Scalable for Growth

Whether you’re syncing 1,000 or 1 million records, Stacksync’s pricing and architecture scale with your needs. Usage-based pricing ensures you only pay for what you use, with decreasing costs as your data volume grows.

Support for Complex Scenarios

• Multi-system environments: Sync HubSpot with multiple CRMs, ERPs, and databases at once
• Custom workflows: Build advanced automations triggered by any data event
• Enterprise security: Choose processing regions, enforce SSO, and manage access with RBAC

Example: A logistics company uses Stacksync to sync customer and order data between HubSpot, Salesforce, and NetSuite, reducing manual reconciliation time by 40% and saving $30,000 annually in integration costs.

The Shift to Operational Integration

In 2024, more organizations are moving beyond analytics-focused ETL tools to operational integration platforms that support real-time business processes. As customer expectations for instant service rise, the ability to sync data across systems in real time is no longer optional.

Framework: The Modern Data Stack

The modern data stack model emphasizes modular, API-driven systems connected by flexible integration platforms. Stacksync fits this model by offering:

• Real-time, event-driven architecture
• Support for both operational and analytical data flows
• No-code and low-code configuration for business and technical users
