The short version

  • Only Odoo has a free tier, so it costs nothing to try first.
  • 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; Odoo the free plan is limited to one app, so any second module moves the whole account to a paid per user plan
  • They diverge on capability: Deltek covers Project accounting, Odoo covers Sales management.
  • Prices and features above were last checked on 30 August 2026.
