NetSuite OpenAir: Complete Guide to Professional Services Automation in 2026

Professional services organizations, consulting firms, IT services companies, engineering practices, marketing agencies, face a unique operational challenge: their primary asset (people) is also their primary cost, and every billable hour either captured or lost directly affects revenue. NetSuite OpenAir is Oracle's Professional Services Automation (PSA) platform designed to solve this problem, connecting project delivery, resource management, time and expense capture, and client billing in one system.

This guide explains what OpenAir does, when it is the right choice, and how to implement it effectively alongside or integrated with NetSuite's core financials.

What Is Professional Services Automation?

PSA platforms sit at the intersection of project management, resource planning, and financial management for services businesses. A complete PSA system manages:

• Project lifecycle: From opportunity (pre-sale) through delivery, billing, and closure
• Resource management: Matching available staff to project demand based on skills, availability, and utilization targets
• Time and expense capture: Accurate recording of billable and non-billable time against projects, clients, and activities
• Client billing: Generating invoices based on time and materials, fixed-fee milestones, or subscription arrangements
• Revenue recognition: Recognizing revenue according to project progress and contract terms (ASC 606)
• Project profitability: Real-time visibility into margin by project, client, practice, and resource

NetSuite OpenAir Core Capabilities

OpenAir was a standalone PSA tool (acquired by NetSuite in 2008) that has since been deeply integrated with NetSuite's ERP platform. Its core capabilities include:

Project Management

OpenAir provides a full project management workspace including task hierarchies, project templates, milestone tracking, dependency mapping, and Gantt charts. Project managers create work breakdown structures that map directly to the billing structure, tasks are assigned billing types (T&M, fixed fee, not billable) so time entry automatically flows to the correct invoice calculation.

Resource Management

OpenAir's resource management module is one of its strongest differentiators. It provides:

• Resource availability calendar showing capacity vs. bookings across all staff
• Skills and certifications tracking for competency-based staffing
• Utilization reporting (actual vs. target billable hours) by resource, team, and practice
• Forecasted utilization based on current bookings and pipeline projects
• Approval workflows for staffing requests across practice areas

Time and Expense

OpenAir provides mobile-first time entry with weekly timesheets, daily time logs, and GPS-enabled expense capture. Time is submitted against specific projects and tasks, with approval workflows routing timesheets to project managers. Expense reports with receipt attachment flow through the same approval chain. All approved time and expenses are available for immediate billing.

Billing and Invoicing

OpenAir's billing engine supports all major professional services billing models:

• Time and materials: Billable hours × rate, with custom rate cards by resource grade, client, or project
• Fixed fee: Invoice on completion or on defined milestone events
• Capped T&M: Time and materials up to a fixed maximum, common in government and healthcare consulting
• Retainer/recurring: Monthly recurring invoices for managed services or ongoing advisory work
• Blended: Multiple billing arrangements on a single project (e.g. fixed fee for Phase 1, T&M for Phase 2)

OpenAir vs NetSuite Projects Module

NetSuite has a native Projects module that provides basic project tracking. Understanding when to use the Projects module versus OpenAir is a critical decision:

Capability	NetSuite Projects	NetSuite OpenAir
Project task management	Basic	Advanced (templates, dependencies, Gantt)
Resource scheduling	Minimal	Full capacity planning + utilization
Time entry UI	Basic timesheet	Purpose-built, mobile-optimized
Expense management	Basic	Full with receipt capture, policy enforcement
Billing complexity	Simple T&M or fixed	All billing models including blended
Revenue forecasting	Limited	Pipeline-to-revenue forecasting
PSA reporting	Basic	Utilization, realization, margin by dimension
Additional license cost	Included	Additional per-user license

Rule of thumb: Use NetSuite's native Projects module for product companies with occasional professional services revenue. Use OpenAir when professional services is a primary business model with 10+ consultants and complex resource management needs.

OpenAir-NetSuite Integration

One of OpenAir's key strengths for NetSuite customers is the native, pre-built integration between the two systems. This integration synchronizes:

• Customers and contacts (bidirectional)
• Approved time and expenses → NetSuite invoices
• Project revenue → NetSuite financials
• Employee and resource records
• Purchase orders and vendor bills

The integration eliminates the manual data transfer that plagues firms using disconnected systems, project data in one tool, billing in another, and financials in a third. With OpenAir and NetSuite connected, an approved timesheet flows to a draft invoice to posted revenue automatically.

Key Metrics OpenAir Enables

Services businesses using OpenAir gain visibility into the KPIs that determine financial performance:

• Billable utilization rate: Billable hours ÷ available hours (target: 70 to 80% for consulting)
• Realization rate: Invoiced revenue ÷ potential revenue at standard rates (reflects discounts and write-offs)
• Project margin: Revenue − direct project costs ÷ revenue (by project, client, practice)
• Days Sales Outstanding (DSO): How long it takes to collect invoiced revenue
• Revenue per billable head: Total revenue ÷ number of billable staff

NetSuite OpenAir vs. Sage Intacct and Certinia

Professional services firms evaluating PSA and financials together usually also look at Sage Intacct paired with a separate PSA tool, or Certinia (formerly FinancialForce) running on the Salesforce platform. Certinia runs natively on Salesforce, which is relevant for firms already running their CRM there. Sage Intacct provides dimensional financial reporting aimed at firms with complex multi-entity structures. NetSuite with OpenAir keeps project delivery, billing and general ledger in one system, rather than a PSA tool connected to a separate financial platform, which requires the connection between the two to be built and maintained. Which platform fits depends on a firm's existing CRM platform, reporting requirements and how much of the PSA-to-financials integration it wants to manage itself.
