Best Software for Engineering Firms in 2026 (7 Platforms Compared)

Engineering firms run on three numbers most software cannot get right: estimate at completion (EAC), utilization rate, and overhead absorption. Get those wrong and you cannot tell whether last month was profitable, whether your civil group is overbooked, or whether your federal contracts will pass a DCAA audit. Get them right and you can quote with confidence, hire ahead of demand, and renegotiate scope before a project runs red.

This guide compares the 7 platforms engineering firms actually use in 2026. We evaluated them across project budget tracking, EAC and earned value, utilization reporting, expense and timesheet capture, DCAA-aware accounting (where relevant), and client portal experience. We also looked at fit by discipline -- civil firms have different needs than MEP, structural, or multi-discipline AEC shops.

Full disclosure: Deelo is our platform. We will name its strengths and its limitations honestly. The goal is to help you pick correctly, even if "correctly" means a Deltek product or a niche specialty tool. Most engineering firms we talk to overspent on a platform that solved one problem and created three new ones. This guide is meant to prevent that.

Before the list, here is what an engineering firm's software stack has to do. Skip features you will not use. Insist on features you cannot run without.

Project budget and EAC tracking. A static budget is useless on a 9-month project. You need running estimate-at-completion that updates as hours and expenses post, with variance alerts when EAC drifts past contract value. If your software cannot tell you on Tuesday that the project will overrun by Friday, it is not engineering software.

Utilization and resource forecasting. Your billable target is somewhere between 65% and 80% depending on level. You need utilization by person, by team, by discipline, and a forward look at the next 4-12 weeks of resource demand against bench. "We are slammed" and "we are slow" are both expensive guesses without this.

Timesheet and expense capture that does not rely on memory. Engineers will not fill out timesheets retroactively with any accuracy. Capture has to be mobile, fast, and tied to project codes and phases the PM already set up. Expense capture needs receipt OCR and project allocation in the same step.

DCAA compliance (if you do federal work). Federal contracts under FAR Part 31 require segregated direct and indirect costs, daily timesheet entry with audit trail, indirect rate pools and bases, and floor checks. If you ever plan to bid federal -- DOD, DOE, FAA, USACE -- this is not optional.

Client portals and deliverable tracking. AEC clients expect drawing review, RFI, and submittal workflows in a portal, not over email. If your software does not give the client a place to log in and see status, your PMs spend half their week on status updates.

Multi-discipline coordination. A firm that does civil + structural + MEP needs phase-based budget rollups, cross-discipline resource visibility, and unified billing. Otherwise each discipline reports separately and the firm has no single P&L.

Pricing: Free tier. Starter $19/seat/mo. Business $39/seat/mo. Enterprise $69/seat/mo.

Best for: Engineering firms (5-150 staff) doing commercial, municipal, and private-sector work that want one platform for projects, CRM, billing, timesheets, and client portals -- without paying enterprise PSA prices.

What sets it apart: Deelo gives engineering firms project budgets with EAC tracking, time and expense capture against project phases, utilization reporting, an integrated CRM with proposal pipeline, automated invoicing tied to billing milestones, and a client portal -- on one data layer. No syncing between a CRM, a PM tool, a time tracker, an invoicing app, and a portal. The same project record drives every workflow.

Engineering-firm features: Project budgets with phases and tasks, EAC and percent-complete tracking, billable rate by role and project, utilization by person and team, timesheet entry on mobile and desktop, expense capture with receipt OCR, retainer and progress billing, change-order tracking, document storage on the project record, and a branded client portal for status and approvals. The AI assistant works across apps -- ask it to flag projects whose EAC has drifted more than 10% past contract, draft a change-order email to the client, and update the proposal pipeline in one prompt.

Pricing context: A 25-person engineering firm pays roughly $975/mo on Business plan for projects, CRM, time, billing, portal, and 50+ other apps. Deltek Vantagepoint for the same headcount typically runs $4,500-7,500/mo plus implementation.

Limitations: Deelo does not currently have native DCAA-compliant indirect rate pools or floor-check workflows. If you have federal contracts under FAR Part 31, you need a Deltek product or BST10 for that piece (some firms run Deelo for commercial work and Deltek Costpoint for federal work). Deelo also does not have built-in CAD-file revision control -- it stores documents but is not a Newforma replacement for drawing management.

Pricing: Custom quotes; engineering firms typically report $50-150/user/mo plus implementation.

Best for: Architecture and engineering firms with 25+ staff, particularly those bidding on or executing federal contracts who need DCAA-aware project accounting.

What sets it apart: Vantagepoint is the successor to Deltek Vision and is widely deployed across the AEC industry. It includes integrated CRM, opportunity tracking, project management, resource planning, project accounting, and reporting. The accounting engine handles indirect rate pools, multi-company structures, and the kind of revenue recognition rules ASC 606 requires for AEC work. Deltek's marketplace and integrations with Newforma, Bluebeam, and BIM tools are mature.

Engineering-firm features: Opportunity-to-project pipeline, resource forecasting, project budgets with EAC, time and expense, billing (T&M, fixed fee, cost-plus, retainer), DCAA-compliant accounting in supported configurations, client portal, and dashboards by role.

Limitations: Implementation is rarely under three months and typically costs $25,000-100,000+ depending on firm size and configuration. The interface inherits decisions from a long product lineage and is heavier than newer platforms. Smaller firms (under 20 staff) are usually better served by Deltek Ajera or a lighter platform. Total cost of ownership is the highest on this list.

Pricing: Custom quotes; firms typically report $40-90/user/mo.

Best for: Smaller architecture and engineering firms (5-50 staff) that want Deltek's project accounting maturity without Vantagepoint's complexity.

What sets it apart: Ajera is purpose-built for small-to-mid A/E. It handles project setup, time and expense, billing, and accounting in one system, with reporting templates designed for AEC. Many regional civil and structural firms run on Ajera because it is faster to deploy than Vantagepoint and the per-user cost is lower.

Engineering-firm features: Project budgets, time and expense, multi-rate billing, percent-complete revenue recognition, A/R and A/P, project reports, and a client portal.

Limitations: CRM and pipeline tracking are weaker than Vantagepoint or Deelo. Resource forecasting is functional but less sophisticated. Like other Deltek products, the interface is workmanlike rather than modern. If you outgrow Ajera you will likely migrate to Vantagepoint, which is non-trivial.

Pricing: Enterprise pricing; usually only quoted to firms 100+ staff.

Best for: Large engineering firms, multi-discipline AEC enterprises, and firms with complex multi-entity, multi-currency, or government-contract cost structures.

What sets it apart: BST10 is built specifically for AEC and competes with Deltek at the enterprise tier. It handles multi-company consolidation, multi-currency billing for international work, complex indirect rate structures, and integrates with major ERPs and document management systems. Reporting depth is one of its strengths -- firm leadership can see profitability by client, project type, office, principal-in-charge, or discipline without custom report builds.

Engineering-firm features: Project accounting, resource management, time and expense, billing, AR/AP, GL, multi-entity consolidation, indirect rates, and reporting.

Limitations: BST10 is enterprise-grade and priced accordingly. Implementation is a multi-quarter project. It is overkill for most firms under 100 staff. The platform is robust but the interface is utilitarian.

Pricing: Custom quotes; widely cited in the $50-120/user/mo range.

Best for: Engineering firms with significant federal contract revenue who need DCAA compliance as a first-class concern, not a configuration option.

What sets it apart: Unanet is one of the most commonly used platforms among small-to-mid government contractors and AE firms with federal work. Its timesheet, indirect rate, and reporting features are designed around DCAA expectations. Many firms report passing audits with less back-and-forth on Unanet than on more general platforms.

Engineering-firm features: DCAA-compliant timesheets, indirect rate pools, project accounting, resource planning, billing (including federal billing types like cost-plus-fixed-fee and T&M), and CRM in their CRM module.

Limitations: Unanet's roots are in GovCon, not pure A/E, so some AEC-specific workflows (drawing review, BIM integrations) are weaker than Deltek or Newforma. The CRM module is less mature than Vantagepoint's. Firms doing 100% commercial work usually do not need Unanet's GovCon depth and pay for features they will never use.

Pricing: Custom quotes; firms commonly report $40-80/user/mo.

Best for: Mid-size architecture and engineering firms that want AEC-purpose-built ERP with a more modern user experience than legacy Deltek products.

What sets it apart: InFocus is a single-database ERP built for AEC, covering CRM, project management, accounting, time, expense, and billing. The interface is more contemporary than Deltek's older products, and many firms cite faster onboarding for new hires. It supports the project-accounting concepts engineering firms expect: indirect rates, multi-rate billing, percent-complete revenue, and EAC.

Engineering-firm features: Opportunity pipeline, project setup, budgets and EAC, time, expense, billing, accounting, reporting, and dashboards.

Limitations: InFocus has a smaller install base and partner ecosystem than Deltek, which can matter when you need consultants, training resources, or third-party integrations. Federal-contract features are present but typically a notch behind Unanet for firms doing heavy GovCon work.

Pricing: Per-user, per-module; firms commonly report $25-65/user/mo depending on modules selected.

Best for: Smaller engineering and architecture firms (1-25 staff) that want strong time tracking, billing, and project management without the overhead of a full ERP.

What sets it apart: BQE Core is modular -- you buy CRM, Projects, Billing, Accounting, and HR separately. For firms that just need time, expense, and billing on top of QuickBooks, the lighter footprint and lower price point are attractive. The mobile app for time entry is one of the better ones in this category.

Engineering-firm features: Time and expense, project budgets, billing (multiple rate structures), retainer tracking, basic CRM, and reporting.

Limitations: Core is not a full AEC ERP. Indirect rate handling is limited compared to Deltek, BST10, or Unanet. Federal-contract suitability depends heavily on configuration and supplementary processes; firms with serious DCAA exposure usually need more. As you grow past 25-30 staff, the modular pricing can start adding up.

Two more platforms come up constantly in engineering firm RFPs and deserve a note.

Newforma is project information management for AEC -- drawing review, RFI, submittal, transmittal, and email filing tied to projects. It is not an ERP and does not handle accounting or billing. Most firms run Newforma alongside Deltek, BST10, or Deelo for the project-document side, not as a replacement for project accounting. If your bottleneck is drawing coordination and submittal turnaround, Newforma is the answer; if it is project profitability or utilization, Newforma will not solve that.

Replicon PSA is a professional services automation platform with strong time tracking, project costing, and billing, used by some engineering and consulting firms that prioritize time accuracy over AEC-specific workflows. It is broader than BQE Core but lighter than Deltek. For firms that are more time-and-billing-driven than project-document-driven, Replicon can be a fit. For firms that need AEC-specific workflows, Deltek, BST10, or Clearview InFocus typically win.

Pick by the constraint that will hurt the most if you get it wrong.

By discipline. A civil engineering firm doing land development, municipal work, and survey coordination has different priorities than an MEP firm running long projects with heavy submittal volume, or a structural firm running shorter design contracts. Civil firms often weigh utilization and multi-project resource forecasting most heavily; MEP firms care about RFI and submittal turnaround (often pairing an ERP with Newforma); structural firms lean toward fast project setup and clean billing. Multi-discipline firms care most about cross-discipline budget rollups and unified P&L.

By federal vs commercial mix.

- 0% federal: Deelo, BQE Core, or Clearview InFocus depending on size - 1-25% federal: Vantagepoint or Ajera (DCAA-aware but not GovCon-first) - 25%+ federal: Unanet or Vantagepoint with GovCon configuration - Multi-entity, international, or 100+ staff with complex cost structures: BST10

By firm size.

- 1-10 staff: Deelo, BQE Core, or Replicon PSA - 10-50 staff: Deelo, Ajera, Clearview InFocus, or BQE Core - 50-150 staff: Vantagepoint, Clearview InFocus, Unanet, or Deelo (commercial) - 150+ staff: Vantagepoint or BST10

By role of project documents. If drawing review, RFIs, and submittals are your operational bottleneck, plan for Newforma alongside whichever ERP you choose. No platform on this list replaces Newforma cleanly for AEC document workflows; pretending otherwise leads to a half-implemented document strategy.

By total cost of ownership, not sticker price. Deltek Vantagepoint at $100/user/mo plus a $60,000 implementation costs a 25-person firm roughly $390,000 over 3 years. Deelo on Business plan for the same firm runs roughly $35,000 over 3 years. The decision is not always price -- if you need DCAA compliance and you do not have it, you risk a contract -- but TCO has to be in the conversation.

The best platform is the one that matches your actual mix of work, your actual size, and your actual constraints. Buy for the firm you are, not the firm you imagine being in five years. You can change platforms when the firm changes.
