The short version

  • Each has a real cost: Deltek not one product but a portfolio, including Costpoint, Vantagepoint, Maconomy, Ajera, ComputerEase, GovWin IQ and Replicon, so the right choice depends on the industry before the feature set; Netsuite OpenAir openAir is a separate application from NetSuite rather than a module of it, so customers, projects and employees exist in two places and a synchronisation must be configured, monitored and repaired when it drifts.
  • They diverge on capability: Deltek covers Time and expense, Netsuite OpenAir covers Timesheets and expenses.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Deltek

  • Not one product but a portfolio, including Costpoint, Vantagepoint, Maconomy, Ajera, ComputerEase, GovWin IQ and Replicon, so the right choice depends on the industry before the feature set
  • Pricing is not published anywhere and requires contacting sales
  • Built around project-based industries such as government contracting, architecture and engineering rather than general business

Netsuite OpenAir

  • OpenAir is a separate application from NetSuite rather than a module of it, so customers, projects and employees exist in two places and a synchronisation must be configured, monitored and repaired when it drifts.
  • It overlaps with NetSuite's own project and services capability, so buyers inside the Oracle estate face a choice between two products from the same vendor and rarely get a straight comparison from the sales conversation.
  • The product has been renamed and repositioned more than once, which leaves documentation, training material and community knowledge fragmented across names and makes it harder to establish what applies to your version.
  • Licensing is per user, so a firm with many occasional timesheet submitters pays full seats for people who sign in twice a month, and the model suits billable-heavy organisations far better than mixed ones.
  • The user interface and administration reflect the product's age rather than current design conventions, which raises training effort and makes consultant adoption of timesheet discipline harder than it needs to be.

Answered from the vendors’ own pages

Deltek: How much does Deltek Costpoint cost?

Deltek does not display pricing for Costpoint or other products on its website. Enterprise ERP pricing requires contact with Deltek sales.

Source
Netsuite OpenAir: Is OpenAir part of NetSuite?

No. It is a separate Oracle application that integrates with NetSuite. It is sold alongside NetSuite and often bought by NetSuite customers, but it has its own data model, interface and administration.

Deltek: What is the cost of Deltek Vantagepoint for architecture firms?

Deltek does not publish Vantagepoint pricing on its website. Pricing depends on firm size, employee count, and feature requirements.

Source
Netsuite OpenAir: Should I use this or NetSuite's own project modules?

If your problem is invoicing project work and tracking basic costs, NetSuite's own capability may be enough and avoids a second system. If your problem is resource planning, skills-based staffing and utilisation forecasting across a large delivery organisation, that is what OpenAir was built for.

Deltek: Do Deltek cloud ERP solutions charge per user?

Deltek offers cloud ERP products but does not disclose per-user, per-month, or subscription rate information on its public website.

Source
Netsuite OpenAir: Can it be used without NetSuite?

Yes, it can run against another finance system, but then you are building and maintaining that integration yourself, which removes the main reason most buyers choose it over an independent professional services automation product.

Netsuite OpenAir: What is the hardest part of implementing it?

Getting consultants to submit accurate timesheets on time, and agreeing how revenue recognition should work on fixed price engagements. Neither is a software problem, and both determine whether the reports are trusted.
