The GSI advantage

The only HubSpot Diamond Partner that's also an Oracle NetSuite partner

Pure-play HubSpot agencies connect to NetSuite through third-party middleware. Flawless Inbound, backed by GSI's ERP engineering team, architects the integration at the data layer, meaning cleaner data, fewer failure points, and no middleware vendor in the middle of your lead-to-cash process.

What the integration enables
- Leads in HubSpot auto-create customer records in NetSuite at close
- Real-time inventory and pricing visible to sales reps in HubSpot
- Marketing segmentation using NetSuite purchase history and order value
- Invoice, payment, and renewal data visible in HubSpot for customer success
- Custom object synchronization between both systems
Who this is for
- Manufacturing and distribution companies on NetSuite
- Professional services firms using NetSuite for project accounting
- B2B companies with complex quote-to-cash workflows
- Companies replacing NetSuite's native CRM with HubSpot

Flawless was able to outline a solution taking the constraints of HubSpot into consideration and ultimately developed integrations with Stripe and AWS.
