Deltek Review 2026: Is It Worth It or Too Complex?

Deltek vs Milient Software: At a Glance 

Who is Deltek best for?

Deltek Vantagepoint is a project-based ERP platform designed specifically for architecture, engineering and consulting firms. It brings project management, resource planning, CRM, financial management and reporting together within one system, giving firms visibility across the full project lifecycle.

Target Audience

Deltek Vantagepoint is primarily designed for project-based professional services organisations that need detailed oversight of projects, people and finances.

Its target audience includes:

• • • • Architecture firms managing multiple projects, budgets and resources.
      • Engineering firms requiring detailed project and financial oversight.
      • Consulting and professional services firms managing client projects, utilisation and profitability.
      • Growing and larger project-based firms that need project, resource, CRM and financial information connected within one system.

Key Features

Project Management: Plan and track projects throughout their lifecycle, with dashboards and project-specific KPIs helping teams monitor project health, budgets and profitability.

Resource Management: View employee availability and utilisation to identify over- or underutilised team members, allocate people to projects and forecast future staffing requirements.

Financial Management & Billing: Manage project accounting, budgets, expenses, accounts payable and receivable, billing and invoicing while monitoring project profitability and cash flow.

CRM & Pipeline Management: Connect client and opportunity information with project data, helping firms manage relationships, opportunities and their future pipeline within the wider ERP.

Business Intelligence & Reporting: Bring project, resource and financial information together to provide greater visibility into company and project performance.

AI-Powered Tools: Deltek's Dela AI capabilities can surface project risks, answer questions using company data, automate routine processes and provide recommendations to project managers. Recent updates have also added AI-assisted timesheet and absence-policy checks.

Positives

• • • • Comprehensive functionality: Vantagepoint combines project management, resource planning, CRM and financial management rather than requiring separate systems for each area.
      • Built specifically for project-based firms: Its functionality is designed around the requirements of architecture, engineering and consulting businesses rather than being a generic ERP.
      • Strong financial visibility: Project managers can monitor budgets, planned and actual spend, profitability and other project KPIs.
      • Detailed resource planning: Firms can monitor capacity and utilisation and match employees to project demand.
      • Growing AI capabilities: Dela is increasingly being incorporated into project, finance and administrative workflows to automate tasks and highlight potential issues earlier.

Negatives

• • • • Learning curve: With a wide range of ERP functionality, Vantagepoint can take time for new users to learn. A 2026 Gartner Peer Insights reviewer noted that it "Takes some time to learn the system".
      • Complexity: Bringing CRM, projects, resources, accounting and reporting into one platform provides extensive functionality, but may be more than smaller firms require.
      • Setup and administration: User comparisons on G2 indicate that setup and administration can be challenging, with Vantagepoint receiving a 6.8/10 Ease of Setup score in one current comparison.
      • Limited pricing transparency: Deltek does not publish standard Vantagepoint prices publicly, meaning firms need to contact the company for a quote.

Customer Reviews

Positive reviews

"It does its job. It's reliable. It has functionality especially for management and accounting departments. Overall, it's a solid program with proven results and a user base that reinforces trust."

"I liked the integration between each facet of the program. It reminds me of SAP in that information entered in one module is carried through to others."

Negative reviews

"It's a bulky program compared to the web based program I use now. It wasn't compatible with some browsers so I had IE just for timesheets. User interface wasn't the most intuitive and customer service wasn't built in. Therefore I had to ask my accounting manager for her to contact customer service with questions."

"The interface in Deltek Vision is clunky. The functionality is there, but the refresh time is slow, and autofill options that you think would be automatic are not present. For instance navigating to a page does not automatically set your cursor to the first entry cell in the page."

Pricing

Deltek does not publicly list standard pricing on its website. Firms need to contact Deltek directly for pricing based on their requirements, making it harder to estimate the total cost before speaking with its sales team.

No pricing screenshot included because Deltek does not publicly display standard Vantagepoint pricing.

Key features

Project Flow combines day-to-day project management with the financial visibility AEC firms need to understand how their projects are performing. Three features are particularly relevant for firms considering an alternative to Deltek Ajera.

Real-time time and budget tracking

Project Flow puts current hours, expected hours and budgeted hours side-by-side, giving project managers a live view of how work is progressing against budget. This makes it easier to identify potential overruns before they become bigger profitability problems.

Rather than waiting until the end of a project to understand its financial performance, teams can use up-to-date project data to make decisions throughout its lifecycle.

Phase-level project planning

coordination and technical design, across a visual timeline. Multiple projects can also be viewed together, helping firms understand what's happening across their wider portfolio.

This is particularly useful for architecture and engineering firms managing complex, multi-phase projects where schedules, budgets and resources need to remain aligned as work progresses.

Resource allocation and planning

Project Flow lets firms define roles such as Project Manager, Architect or Intern, assign team members and set role-specific hourly rates. Teams can then track billable and non-billable allocation at role level.

By connecting resource decisions with project and financial information, firms get a clearer picture of who is working where and how those decisions affect budgets, without relying on separate resource planning spreadsheets.

Where Milient shines

• • • AEC-specific project management: Project Flow is tailored to architecture, engineering and consulting firms rather than being a general-purpose project management platform.
    • Financial visibility without spreadsheet overload: Live budget, fee, time and invoicing data gives project leaders a clearer view of performance while reducing reliance on Excel.
    • Ease of use: Project Flow is designed to make detailed project information accessible, with users specifically highlighting its intuitive interface and visualisation.

Where Milient falls short

• • • • Timesheet experience: Users have noted that it isn't always clear when timesheets have been submitted or validated, and there are currently limitations around approval notifications.
      • No calendar view for logged hours: Users looking to view their recorded project hours within a calendar-style layout may find this functionality limited.

Customer reviews

Project Flow users frequently highlight ease of use and reduced spreadsheet dependency as strengths.

“Very user friendly. The display is easy to understand and I can change my operating language.”

Deltek Review: What’s Our Verdict?

Overall, Deltek is a reliable and established platform with strong functionality, particularly for management, accounting and connected project information.

However, the reviews suggest that its depth can also make it feel bulky, clunky and less intuitive for some users. For larger teams with complex accounting needs, Deltek may be a solid option, but businesses looking for a more modern, user-friendly experience may want to compare alternatives before committing.

Growing AEC firms looking for project and financial control in a more intuitive platform may find Milient Project Flow a simpler alternative.
