NetSuite ⇔ Connectwise PSA Integration

API-to-API integration that keeps your financials and PSA in sync

Overview

Service businesses that run Connectwise PSA for ticketing, project management, and dispatch — and NetSuite for accounting, billing, and financial reporting — face a familiar problem: the same customer, project, and time entry has to live in both systems. Catalyst's NetSuite ⇔ Connectwise PSA integration is a native, API-to-API integration that keeps the two platforms aligned without manual exports, CSV imports, or middleware.

The Challenge

Without an integration, the seams between PSA and ERP show up everywhere. Customers exist in both systems with mismatched IDs. Tickets close in Connectwise but invoices never get cut in NetSuite. Hours logged by techs sit in PSA timesheets and have to be retyped, summarized, or imported manually before they can be billed. Inventory consumed on a service ticket doesn't decrement NetSuite stock. Finance and operations end up reconciling the two systems instead of running them.

The Solution

The Catalyst integration synchronizes the records that matter in both directions:

• Customers and contacts — created or updated in one system, reflected in the other
• Service tickets and projects — visible in NetSuite for billing, costing, and reporting
• Time entries — flow from Connectwise PSA to NetSuite for invoicing
• Products and inventory — kept consistent across catalogs
• Invoices and billing data — generated from NetSuite based on PSA activity

Because the integration is API-to-API, there's no flat-file export, no middleware platform to license, and no custom-coded scripts that break with each update. Field mappings, sync rules, and exception handling are configurable.

Key Capabilities

• Bidirectional customer sync
• Ticket and project visibility in NetSuite
• Automated time-to-invoice flow
• Inventory and item alignment
• Configurable mappings and sync rules
• Exception handling and audit trail

Benefits for NetSuite Users

Service teams stop maintaining two parallel customer lists. Billing speeds up because hours flow automatically from PSA to NetSuite invoices. Finance gets accurate revenue and margin reporting because the data underneath is consistent. And IT and operations stop spending time on data hygiene that could be spent on customer-facing work.

Who It's For

Managed service providers, IT services firms, professional services organizations, and any business running Connectwise PSA alongside NetSuite. Particularly valuable for teams currently using manual processes or homegrown scripts to bridge the two systems.
