Best ERP for Consulting Firms: 10 Tools Reviewed & Compared (2026)

Deltek has been the dominant ERP for engineering and professional services firms for decades. Its Vantagepoint product covers project management, resource planning, CRM, accounting, and business intelligence in one platform. For firms doing government contracting work specifically, Deltek is often the only realistic choice - it handles the compliance requirements (DCAA, FAR) that other tools don't touch.

The utilization and project profitability reporting in Deltek is genuinely strong. It's built around the A&E (Architecture & Engineering) billing model and understands concepts like direct labor, indirect costs, and overhead burdens in ways that general ERP doesn't. If your firm invoices on T&M, fixed-fee, and cost-plus contracts simultaneously, Deltek handles that natively.

The downside is scale and complexity. Implementation projects routinely take 6-18 months and cost $50,000-$200,000+. The interface is not modern. For firms under 50 people who don't need government compliance features, the implementation cost and ongoing admin burden are hard to justify when lighter tools cover the operational basics more efficiently.

Scoro positions itself as an all-in-one business management platform for professional services, and it largely delivers on that promise. It covers project management, time tracking, resource planning, CRM, and financial reporting in one coherent interface. The UX is modern and the onboarding is faster than the enterprise alternatives.

Utilization reporting and project profitability are both solid. The quotes-to-cash workflow (proposal → project → time tracking → invoice) is well-implemented. For agencies in particular, the retainer management and budget tracking features are genuinely useful. Scoro's reporting is flexible enough to build the dashboards that ops directors actually need.

Where Scoro is weaker is in forward resource allocation - the view of who has capacity in the coming weeks is functional but not as sophisticated as dedicated resource planning tools. It's also priced at the higher end of the mid-market tier, which can be hard to justify for smaller firms when the per-seat cost starts adding up.

Kantata is one of the most capable professional services platforms in the market. Resource management is a particular strength - the way Kantata handles skills-based allocation, demand planning, and capacity forecasting is more sophisticated than most alternatives. For firms doing complex resource scheduling across dozens of concurrent projects, it's worth considering.

Project financial management is equally mature. Budget tracking, revenue recognition, and multi-currency billing are all handled well. Kantata integrates with Salesforce natively, which is a meaningful advantage for firms that run their pipeline there and want project data to flow in automatically when a deal closes.

The main limitation is that Kantata is priced and designed for firms that have already scaled. Onboarding takes time, the configuration requires effort, and the pricing model makes it hard to justify under 30-40 seats. Smaller firms often find they're paying for capability they can't yet use.

Productive has emerged as one of the cleaner options in the mid-market professional services space. The interface is well-designed, the onboarding is relatively fast, and it covers the core bases: project management, time tracking, resource planning, budgeting, and invoicing. For teams coming out of a mix of disconnected tools (Harvest for time, Trello for projects, spreadsheets for budgets), Productive is a significant step up.

Utilization tracking and project profitability reporting are both functional. The budget vs. actual view per project is clear and updates as time is logged. Productive has been adding features at a fast pace, and the product has improved substantially in the last two years.

The ceiling is starting to show as firms scale past ~100 people. Resource planning works well at smaller team sizes but can become unwieldy with complex organizational structures. It also lacks some of the financial depth (multi-entity, revenue recognition) that larger firms need. But as a starting point for a consultancy that's serious about getting operational visibility, it's a strong option.

BigTime has been one of the most popular professional services tools for mid-size firms precisely because it does time tracking and billing extremely well. The timesheet interface is fast, the billing workflow is flexible, and the WIP (Work In Progress) management features are genuinely useful for firms managing retainer clients and milestone billing.

Utilization reporting is available and reasonably detailed - you can see billable vs. non-billable time by person and by project. The dashboards are customizable. For firms whose primary operational problem is getting accurate time data and turning it into invoices efficiently, BigTime solves that problem well.

The gaps are significant for firms that need the full picture. Resource planning (forward allocation, capacity forecasting) is not a strength - it's functional but not built for serious scheduling. Project profitability reporting works but requires some configuration to get meaningful margin data. And there's no CRM, no proposal tool, no pipeline visibility. BigTime is a strong component, not a full platform.

BQE Core (formerly ArchiOffice/EngineerOffice) is one of the longest-standing platforms specifically built for architecture and engineering firms. It understands A&E billing natively: hourly billing, percentage of construction, not-to-exceed contracts, phase-based project management. For firms working in those models, BQE Core fits out of the box in ways that general platforms don't.

The financial reporting - project performance, profitability by phase, overhead tracking - is strong. The timesheet and expense workflow is mature and well-regarded by the firms that use it. BQE has also invested in a modern interface over the last few years, and the current product is significantly more polished than it was.

The limitation for management consultancies is that BQE Core is very A&E-specific in its mental model. Firms doing strategy consulting, IT consulting, or other non-engineering work will find some of the workflow assumptions don't quite fit. Resource planning is functional but not sophisticated. And the integrations ecosystem is smaller than larger platforms.

NetSuite is a genuine enterprise cloud ERP with capabilities that dwarf everything else on this list. Multi-entity, multi-currency, complex revenue recognition, full GL accounting, automated consolidation - if your firm has reached the scale where those things matter, NetSuite can handle them. It's particularly relevant for consulting firms that have grown through acquisition or operate across multiple geographies.

The professional services module (NetSuite PSA, or SRP for Services Resource Planning) adds project billing, timesheet management, and resource scheduling on top of the core ERP. Large firms that need both a proper accounting backbone and project management in one system often end up here eventually.

For any firm under 100 people, NetSuite is almost certainly the wrong choice. Implementation projects are expensive and slow - 6-18 months is typical, and $50,000-$250,000+ before any subscription fees is not unusual. The configuration complexity is high, the learning curve is steep, and the ongoing admin burden requires dedicated internal resource. Firms that adopt NetSuite too early often find themselves locked into a system they've outgrown in the wrong direction - too rigid to adapt as the business changes.

Accelo covers the basics for small professional services businesses: client management, project tracking, timesheet logging, billing, and retainer management in one platform. The interface is accessible and the setup time is relatively short. For a firm moving off spreadsheets and email at the 5-20 person stage, Accelo provides a meaningful improvement in operational structure.

The CRM component is actually one of Accelo's stronger points - client records, contact management, and the link between sales pipeline and active projects works well. For firms where account management and project delivery blur together, that integration is useful.

The ceiling is real. Utilization reporting is basic. Resource planning is limited. Project profitability visibility is functional but not detailed. As firms grow past 30-40 people, they typically find they're working around Accelo's limitations rather than with its strengths. It's a strong starting point, not a long-term platform for a scaling consultancy.

Teamwork started as a project management tool and has been adding professional services features over time - time tracking, billing, retainer management, and basic resource scheduling are all available. For teams that primarily need project and task management with some billing capability bolted on, it works reasonably well at an accessible price point.

The project management features are genuinely good: task dependencies, milestones, client portals, and collaborative document management are all well-implemented. If your team's primary tool is a project board and you want to add time tracking and invoicing without switching platforms entirely, Teamwork is a logical step.

For consulting firms that need operational intelligence - real utilization rates, project margin tracking, forward capacity forecasting - Teamwork falls short. Utilization reporting is basic. There's no meaningful forward allocation view. Revenue and margin data requires manual extraction or integrations. It's a project tool wearing a professional services hat, not a purpose-built operations platform.
