Deltek Alternatives: Vantagepoint and Ajera Replacements for Professional Services (2026)

Disclosure: Operating publishes this page and is one of the tools discussed. We checked every product claim against vendor pages, documentation and help centers, and we say where staying with Deltek is the better choice. Last updated October 2, 2026.

Short answer: Deltek is a software company, not one product. Most people searching for Deltek alternatives are leaving Deltek Vantagepoint, an ERP for architecture, engineering and consulting firms, or Deltek Ajera, accounting software for small A&E firms. If you must replace the general ledger, WIP and billing, look at Unanet AE or BQE CORE for A&E, or Certinia on Salesforce. If accounting can live in QuickBooks, Xero, Sage Intacct or NetSuite, a PSA such as BigTime, Kantata or Operating can run staffing, time and margins. If only planning is broken, you may not need to leave Deltek.

TL;DR

• Name the product first. Vantagepoint and Ajera have different buyers and different alternatives.
• Vantagepoint: Unanet AE (another A&E ERP), Certinia (Salesforce), Kantata (enterprise PSA), BigTime (PSA with an external ledger) and Operating (PSA for consulting and IT services firms of 30 to 500 people).
• Ajera: BQE CORE (integrated accounting, documented Ajera conversion), Unanet AE, Monograph (small architecture firms on QuickBooks Online) and BigTime.
• The key decision: which system owns the ledger, WIP and invoices after the move. A PSA is not an accounting system.
• Staying can be rational for government cost accounting, A&E billing setups that work, or problems caused by configuration.

Deltek alternatives at a glance

The first two tables split the market by the product you are leaving. The third shows pricing as of October 2026. "Quote-based" means no public price.

What are you actually replacing when you leave Deltek?

You are replacing one Deltek product, and each product owns a different part of the firm. List the jobs it does: CRM, staffing, time, invoicing, WIP, the ledger, or all of them.

Deltek is a product family

Deltek says more than 30,000 organizations use its software. Its ERP line has five products: Costpoint for government contractors, Vantagepoint for A&E and consulting, Maconomy for commercial enterprise, ComputerEase for construction and Ajera for small A&E firms. Deltek also sells Polaris, a PSA for IT and consulting firms "without the overhead of a full ERP".

Some firms still run Deltek Vision. Deltek's upgrade FAQ says Vision 7.6 got its final year-end update in January 2026 and moved to sustaining support. Deltek Cloud access to Vision winds down in the first quarter of 2027.

Deltek Vantagepoint

Deltek calls Vantagepoint an ERP "designed specifically for architecture, engineering, and consulting firms". It covers CRM and pipeline, project management, resource management with skills search and staffing forecasts, time and expense, billing, accounting and approval workflows. A "Front Office only" option runs beside an existing financial system. Deltek says more than 2,000 companies use Vantagepoint and over 80% of them are on Deltek Cloud (vendor claims).

The product is moving. Release 2026.1 added AI insights for timesheet approvals, and 2026.2 added AI policy checks on expenses and an opt-in redesign called Harmony UI. There is a REST API. Two facts matter for CRM-led firms: 2026.1 removed the native Salesforce integration, and the HubSpot connector we found is built by a third party, SyncMatters. Pricing is quote-based.

Deltek Ajera

Deltek positions Ajera as project management and accounting software "for small A&E firms". It is a real accounting system. Its documentation explains that time, vendor invoices, billing and receipts update the general ledger automatically, and that draft invoices collect WIP as work happens. Around that core sit Schedule Manager, dashboards, Ajera Payments and AI features: Ask Dela (cloud only), Timesheet Assist and receipt reading.

Its integration model is older. The Ajera API uses sessions on a single POST endpoint and covers a limited list of records. Ajera Cloud customers can request read-only ODBC access. Deltek still invests: Ajera 10.3 shipped in November 2025, and Deltek says it is "committed to the continuous improvement" of Ajera.

Vantagepoint vs Ajera: the practical difference

Both hold project accounting, so neither is a simple PSA.

Implementation times are G2 review averages for Vantagepoint and Ajera, not Deltek figures. Firms usually move from Ajera to Vantagepoint as complexity grows. Deltek's Environmental Works story describes a firm that grew from 150 to over 300 people across 10 locations before moving (vendor case study).

Why professional-services firms look for Deltek alternatives

Most firms do not leave Deltek because a feature is missing. They leave because using the features they pay for takes too much time, training or specialist help.

• Daily usability. Capterra reviewers rate ease of use at 3.6 out of 5 for Vantagepoint and 3.4 for Ajera. On G2 both score 4.1 overall. This is review evidence, not a measurement.
• Reporting needs an expert. G2 and Capterra reviewers describe custom reports that need SQL or a trained administrator.
• CRM integrations. HubSpot and Salesforce users now need a third-party or custom connector for Vantagepoint, and the Ajera API is limited.
• Change cost. A Vision upgrade, a reconfiguration and a switch all need a partner-led project, so firms compare all three.
• Forward planning. Firms that staff from a moving pipeline want tentative staffing, skills matching and capacity forecasts that managers use every week.

Some complaints describe older versions. Test the current release before you decide.

ERP replacement vs PSA replacement: the four architectures

Leaving Deltek is an architecture decision before it is a vendor decision. You can replace the whole system, split the PSA from accounting, put a PSA between tools you keep, or keep Deltek and replace only planning.

Option 1: Replace Deltek with another integrated platform

CRM, projects, time, billing and accounting stay in one data model. Unanet AE and BQE CORE do this for A&E. Certinia does it on Salesforce. Dynamics 365 Project Operations does it with Dynamics 365 Finance. A timesheet still flows to WIP, invoice and ledger without integrations. The cost is a second large ERP project.

Option 2: Separate the PSA from accounting

The flow becomes CRM, then PSA, then accounting. The PSA owns staffing, time, budgets and margins. QuickBooks, Xero, Sage Intacct or NetSuite owns the ledger, AP and payroll. BigTime, Kantata and Operating work this way. You get better daily tools, but you own an integration and must decide where WIP and revenue recognition live so both systems reconcile each month.

Option 3: Keep your CRM and project tools, put a PSA in the middle

Sales stays in HubSpot, Salesforce or Pipedrive, and delivery stays in Jira or Asana. The PSA turns likely deals into staffing plans, collects time and sends invoices to accounting. Decide which system owns the client, project, rate card and invoice.

Option 4: Keep Deltek, replace only the planning layer

If accounting, billing and WIP work, keep Deltek and add a planning tool. Mosaic documents native connectors for Vantagepoint, Ajera and Vision. Other tools need custom work on the Deltek APIs. There is no financial migration, but you pay two vendors and own a sync.

Illustrative examples: a 120-person IT consultancy that uses Vantagepoint for time, resource plans and invoices and sells in HubSpot is an Option 2 or 3 firm. A 70-person engineering firm with phase budgets, WIP and 15 years of history in Ajera should look at Option 1 or 4.

Best Deltek Vantagepoint alternatives

Grouped by architecture, not by score.

Unanet AE: best for A&E firms that want another integrated ERP

Why consider it: Unanet AE is the closest like-for-like option, with projects, resource scheduling, project accounting, WIP and billing. Its financials include GL, AP, AR, multi-company and revenue recognition, and Unanet CRM is built for AEC pursuits.

Where it is stronger: Unanet says 45% of its AE customers came from Deltek and quotes "low single-digit months" to implement on its switch page (vendor claims).

What you lose: little functional depth, but you still run a full ERP project, and G2 ease-of-use scores are close to Vantagepoint's.

Choose it if you are an A&E firm that needs integrated accounting from a different vendor.

Certinia: best for Salesforce-centric organizations

Why consider it: Certinia runs natively on Salesforce. Professional Services Cloud covers estimation, resourcing, projects and billing, and Financial Management Cloud adds a general ledger and ASC 606 revenue management.

Where it is stronger: deal, project, staffing and finance share one Salesforce data model.

What you lose: A&E-specific workflows. You also need Salesforce licenses, a partner-led rollout and a quote.

Choose it if you are a larger consulting, IT or advisory firm on Salesforce. See Certinia vs Operating.

Kantata: best for complex enterprise staffing

Why consider it: Kantata is a resource-centric PSA with skills matching, forecasting, project accounting, revenue recognition and invoicing, in standalone and Salesforce-native versions.

Where it is stronger: pipeline demand planning, internal and external talent in one pool, and AI agents such as its Expertise Agent. Standard integrations include NetSuite, Sage Intacct, QuickBooks, Xero, Salesforce and HubSpot.

What you lose: the ledger and A&E focus. G2 reviewers mention a learning curve, its security page lists US hosting, and pricing is quote-based.

Choose it if you have hundreds of billable people and an ERP you will keep. See Operating vs Kantata.

BigTime: best for mid-market firms that keep a separate ledger

Why consider it: BigTime focuses on time, expenses, billing and budgets for consulting, engineering and IT firms. Essentials starts at $20 per user per month.

Where it is stronger: billing and time workflows. On G2, it scores 8.8 for ease of use against 7.5 for Vantagepoint. It syncs with QuickBooks, Sage Intacct and NetSuite and integrates with Salesforce and HubSpot.

What you lose: a native ledger. Full resource management sits in the Enterprise tier, and its Resourcing Agent is listed as beta or coming in 2026.

Choose it if billing is your main problem and finance will run the books elsewhere. See Operating vs BigTime.

Operating: best for consulting and IT services firms separating PSA from accounting

Why consider it: Operating (operating.app) is a PSA built around staffing and project economics. Every plan includes skills-based staffing, tentative allocations and a capacity forecast weighted by CRM deal probability. Native integrations bring HubSpot, Salesforce and Pipedrive deals in as tentative projects.

Where it is stronger: it answers "if we win this deal, who works on it, and at what margin?" before the deal closes. Pricing is public: $13, $17 and $21 per person per month billed annually ($15, $19 and $23 monthly). Time tracking, invoicing, revenue recognition and multi-company sit in the higher plans. Enterprise starts at 100 people, with an SLA, custom contract and on-site onboarding. Operating is SOC 2 Type 2 certified, hosts data in Frankfurt, includes SSO on every plan, and has a REST API and a native MCP server with 59 tools for AI agents.

What you lose: Operating has no general ledger, AP, payroll or built-in CRM. Accounting sync is native for Xero and QuickBooks Online, while NetSuite needs the API. There is no Deltek, Jira or Asana connector and no task management. Retainer billing is limited, and custom reporting is less flexible than Deltek's.

Choose it if you are a consulting or IT services firm of about 30 to 500 people, staffing from the pipeline is the main problem, and accounting can live in Xero or QuickBooks Online. Above 500 people, fit depends on complexity.

Mosaic or Deltek Polaris: if you only need a better planning layer

Mosaic says "your ERP remains the financial backbone" and sells itself as the planning engine on top, with connectors for Vantagepoint, Ajera, Vision, Costpoint Cloud, Unanet and BQE CORE. Deltek's own Polaris is another route for IT and consulting firms. Compare it in Operating vs Polaris.

Also considered

• NetSuite SuiteProjects Pro: fits when NetSuite is the ERP. Its three-way Salesforce integration is deprecated. See SuiteProjects Pro alternatives.
• Dynamics 365 Project Operations: $135 per user per month, for Microsoft-standard firms that also run Dynamics 365 Finance.
• Productive, Scoro, Accelo: agency-leaning PSAs. Productive's HubSpot and Salesforce sync need its unpriced Ultimate plan.
• Wrike, Teamwork.com: work management with budgets and time, not project accounting.

Best Deltek Ajera alternatives

Ajera buyers usually need accounting first, so this list leans toward tools that hold a ledger or sit on top of Ajera.

BQE CORE: best for small A&E firms that want integrated accounting

Why consider it: BQE CORE has its own general ledger, and BQE says CORE users do not need QuickBooks. It adds time, billing, project management and resource forecasting.

Where it is stronger: a documented path. BQE's data conversion lists Ajera, Vision and Win2 as sources. On G2, CORE scores 8.5 for ease of use against 7.4 for Ajera.

What you lose: the conversion has a non-refundable fee, excludes payroll and AP data, and can take over 30 days. Accounting and CRM are add-on modules, pricing is quote-based, and there is no native HubSpot or Salesforce connector.

Choose it if you want books and projects in one easier A&E tool.

Unanet AE: best for A&E firms outgrowing Ajera

If more entities, offices or projects make Ajera feel small, Unanet AE is the non-Deltek route in the same direction as an Ajera-to-Vantagepoint upgrade.

Monograph: best for small architecture firms on QuickBooks Online

Monograph combines phase budgets, staffing, time, invoicing and profitability in a visual tool for architects. QuickBooks Online keeps the books through a sync on the Grow and Track plans. QuickBooks Desktop and Xero are not supported. Pricing runs from $45 to $490 per month by headcount.

BigTime: best for firms ready to move the ledger

BigTime fits Ajera firms that want stronger billing and accept QuickBooks or Sage Intacct as the ledger. You lose the built-in link between time, WIP and GL, so plan month-end reconciliation first.

Mosaic: best if you want to keep Ajera

Mosaic reads Ajera clients, projects, phases, employees and time, so Ajera stays the system of record. Ajera Cloud users need ODBC access from Deltek for some of that data.

Why Operating is not on this list: most firms buy Ajera for its ledger and WIP. Operating holds neither, so it only fits an Ajera firm that has already decided to move accounting to Xero or QuickBooks Online.

How to choose the right Deltek alternative

Start with ownership, not features. Decide which system owns the ledger, which owns the CRM, who plans capacity, and how much history must stay live. Then use the table.

Test finalists with your own data: staff a real pipeline deal, close a month with WIP, and build your Monday COO report.

What to consider before migrating from Deltek

Move the data you need to run the business from day one, and archive the rest.

Plan the cutover around money

Cut over at a month-end or year-end. Approve all time, bill what you can, then load open AR and unbilled WIP as opening balances. Reconcile both against Deltek, and run one billing cycle in parallel.

Check extraction and access

Vantagepoint data comes out through its REST API, and Ajera data through its API, reports or ODBC. Ask Deltek in writing how long you keep read-only access after the contract ends, because audit trails and historical margins often stay there. Confirm scope, fees and exclusions for any vendor migration service.

Rebuild integrations on purpose

List every integration and scheduled report that touches Deltek: payroll, HR, CRM, BI and banking. See our PSA rollout guide and PSA vs ERP for system ownership.

When you should stay with Deltek

Stay when Deltek's accounting depth does real work for you and the pain sits in configuration, training or one missing layer.

• Government contracting. DCAA audits, indirect rates and CAS or CMMC duties belong in a GovCon ERP such as Costpoint or Unanet GovCon. Commercial PSAs do not claim this.
• Integrated accounting you rely on. If WIP, phase billing and the ledger work, a PSA alone splits them across systems.
• Deep configuration and history. Price the rebuild of custom fields, reports and integrations before you compare license fees.
• The problem is configuration. A partner review, Harmony UI or an Ajera-to-Vantagepoint move may fix it for less.
• Security scope. Deltek's compliance page lists SOC 1 and SOC 2 Type II for both products. ISO 27001 and FedRAMP cover other Deltek products.

FAQ

What is the best alternative to Deltek?

It depends on the product. For Vantagepoint, A&E firms compare Unanet AE, and Salesforce-led firms compare Certinia or Kantata. For Ajera, small A&E firms compare BQE CORE and Monograph. Consulting firms that keep accounting in Xero or QuickBooks can use Operating or BigTime.

What are Deltek's main competitors?

In A&E: Unanet AE, BQE CORE and Monograph. In professional services: Kantata, Certinia, BigTime, NetSuite SuiteProjects Pro and Operating. In government contracting, Unanet GovCon competes with Costpoint.

Is Deltek Vantagepoint a PSA or an ERP?

Deltek calls it an ERP. It includes PSA functions such as resource planning, time and projects, plus CRM, billing and accounting. Replacing it with a PSA alone means moving the ledger elsewhere.

What is the difference between Ajera and Vantagepoint?

Ajera is accounting-led software for small A&E firms. Vantagepoint is a broader ERP for A&E and consulting firms of any size, with native CRM, deeper resource planning, workflows and a REST API.

What is replacing Deltek Ajera?

Nothing has been announced. Deltek shipped Ajera 10.3 in November 2025 and says it keeps investing. Deltek Vision, not Ajera, is being replaced by Vantagepoint.

What is the best Deltek alternative for consulting firms?

Consulting firms rarely need A&E billing, so a PSA beside a separate ledger often fits. Operating suits firms of 30 to 500 people that staff from the pipeline.

What is the best Deltek alternative for architecture and engineering firms?

A&E firms that need integrated accounting shortlist Unanet AE and BQE CORE. Small studios on QuickBooks Online often choose Monograph.

What is the best Deltek alternative for resource planning?

If you keep Deltek, Mosaic has native Deltek connectors. If you replace the operational layer, Operating and Kantata focus on skills, tentative staffing and capacity forecasts.

Can a PSA replace Deltek Vantagepoint or Ajera?

A PSA can replace staffing, time, budgets, margins and often invoicing. It does not replace the general ledger, AP or payroll, so you need QuickBooks, Xero, Sage Intacct or NetSuite beside it.

How does Deltek compare with BigTime?

Vantagepoint and Ajera include a ledger. BigTime syncs to QuickBooks, Sage Intacct or NetSuite instead. BigTime starts at $20 per user per month and scores higher on G2 for ease of use.

Unanet AE is the closest match to Vantagepoint: an A&E ERP with project accounting, GL and CRM. Both score 4.1 on G2. Unanet GovCon competes with Costpoint.

How does Deltek compare with Operating?

Vantagepoint and Ajera are ERPs with a ledger. Operating is a PSA without a ledger or built-in CRM. It connects HubSpot, Salesforce or Pipedrive to staffing and margins, and syncs invoices to Xero or QuickBooks Online.

What should you consider before migrating from Deltek?

Decide which system owns the ledger, CRM and invoices. Move active clients, projects, people, rates, open AR and unbilled WIP. Archive closed history, keep read-only access, and cut over at month-end.
