NetSuite ⇔ Connectwise PSA Integration
API-to-API integration that keeps your financials and PSA in sync
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 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 technicians sit in PSA timesheets and have to be retyped, summarized, or imported manually before they can be billed.
Inventory consumed on a service ticket does not 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 and 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 is no flat-file export, no middleware platform to license, and no fragile custom script that breaks with every update.
Field mappings, sync rules, and exception handling are configurable.
Key Capabilities
- Bidirectional customer sync — keep customer and contact data aligned across systems
- Ticket and project visibility — bring PSA activity into NetSuite for billing and reporting
- Automated time-to-invoice flow — move technician time from Connectwise PSA into NetSuite invoicing
- Inventory and item alignment — keep products, items, and inventory activity consistent
- Configurable mappings — define how fields and records should sync
- Exception handling and audit trail — identify sync issues and maintain visibility into integration activity
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 more accurate revenue and margin reporting because the data underneath is consistent.
IT and operations spend less time on data hygiene and more time supporting customers.
Who It’s For
NetSuite ⇔ Connectwise PSA Integration is built for managed service providers, IT services firms, professional services organizations, and any business running Connectwise PSA alongside NetSuite.
It is especially valuable for teams currently using manual processes, CSV imports, or homegrown scripts to bridge the two systems.
