How to Select an ERP System for Your Consulting Firm

This article explains how to select an ERP system for a consulting firm, covering the main ERP types, a practical evaluation checklist, and what to look for in a software partner.

Why it matters: Generic accounting tools can't handle project-based work, so choosing the wrong ERP costs consulting firms visibility, profitability, and client trust.

Key Takeaways

  • Project-based ERP fits consulting firms best: General accounting software can't tie every transaction to a project, so firms often outgrow it fast.
  • Build a selection checklist before you shop: Compare business-process fit, implementation approach, and total cost of ownership across each ERP option.
  • Deltek ERP is built for consulting firms: It centralizes projects, resourcing, and financials on one platform.

Selecting and implementing ERP software teaches consulting firms quickly that not all solutions are created equal. Enterprise Resource Planning (ERP) and Professional Services Automation (PSA) platforms vary widely, and so does the experience of choosing and rolling one out. That variation is exactly why due diligence matters: firms that go in informed, comparing options against their actual workflows rather than assuming "bigger is better", set themselves up for a smooth transition.

When consulting firms choose the right system and take the right steps for a successful implementation, the result is genuinely transformative: better visibility into projects, faster billing cycles, and less manual reconciliation.

What is ERP for Consulting Firms?

ERP for consulting firms is software that connects every transaction, time, expenses, invoices, and resources to a specific project, client, and general ledger account. Unlike generic accounting tools, project-based ERP gives consulting firms one system for financials, resource planning, and client management, so leaders can see project profitability and utilization in real time.

Delivering client projects or engagements adds another layer to a consulting firm's ERP requirements, one that generic, off-the-shelf solutions often can't accommodate. A true project-centric ERP is built for this: every transaction ties to a general ledger account, an organization (department or business unit), and a project. That three-way link is what makes precise financial reporting, real-time project status, and accurate resource planning possible, and it's where the real return on an ERP investment comes from.

A comprehensive, project-based ERP does cost more than an almost-free accounting tool. But that comparison misses the point. Generic accounting tools aren't built for project-based work, so firms end up spending time elsewhere: reconciling data by hand, chasing down project profitability in spreadsheets, or making decisions on incomplete information. The right ERP shifts the cost from ongoing manual work to a system that does it for you.

Benefits of ERP for Consulting Firms

ERP systems provide consulting firms with improved efficiency and productivity. By integrating various business processes into a single system, an ERP eliminates duplication of effort and streamlines workflows. Automating tasks such as invoicing, project management, and client communication allows consultants to focus more on strategic activities that drive business growth.

Benefits of ERP include:

  • Efficiency and Productivity: Streamlines processes and automates tasks, freeing time for strategic activities.
  • Visibility Data Management: Centralizes data for accurate, real-time information and better decision-making.
  • Project Management: Enhances resource allocation, time, and expense tracking.
  • Financial Management: Improves budgeting, forecasting, and cash flow oversight.
  • Client Management: CRM options provide better client relationship management and service delivery.
  • Regulatory Compliance: Ensures compliance through proper record maintenance and audit trails.
  • Collaboration: Facilitates better team communication and document management.

The visibility an ERP provides across the business allows for better decision-making and the ability to pivot quickly when projects or market conditions change, resulting in better performance across the firm. Independent industry research from SPI shows that firms with better visibility perform remarkably better, with increased utilization, higher revenue, and greater profitability.

Exploring Different Types of ERP Systems for Consulting Firms

When selecting an ERP system for your consulting firm, it's essential to explore the variety of systems available. Broadly classified, ERP systems can be on-premises, cloud-based, hybrid, or project-based.

On-Premises ERP

On-premises ERP systems are installed locally on a company's hardware and servers. This type of ERP offers full control over IT infrastructure, but it requires significant upfront investment and ongoing maintenance from an internal IT team.

Cloud-Based ERP

Cloud-based ERP, also known as SaaS (Software as a Service) ERP, is hosted on the vendor's servers and accessed over the internet. It typically offers a lower initial cost, easier scalability, and simpler updates than an on-premises ERP system.

Hybrid ERP

Hybrid ERP combines elements of both cloud and on-premises ERP models, giving firms the flexibility to run specific applications on-premises while hosting others in the cloud.

Project-Based ERP

Project-based ERP is tailored to industries that run on projects, including consulting firms. These systems include specialized modules for project management, resource planning, and time tracking, so every transaction ties back to a specific engagement. Deltek ERP is purpose-built for project-based businesses, connecting projects, people, and financials from the first pursuit through project closeout.

When considering different ERP types, weigh each option against your consulting firm's current business processes, technical requirements, and long-term goals. Make sure it can handle the complexity of your services and client relationships as you grow.

How to Select the Right ERP Solution for Your Consulting Firm

Selecting the right ERP solution is crucial for improving business operations within a consulting firm.

Start the selection process by defining your firm's unique business requirements, then shortlist ERP systems that align with those goals and processes. Investing time up front to build an ERP selection checklist pays off well before contract signing.

#1 Build a Checklist

Remember, you are searching for a solution to solve unique problems in your business. Some issues are apparent, but many are not. There will be many factors to consider, but here is a baseline to help get you started:

Evaluation Criteria What to Look For Why It Matters
Business Process Fit How closely the system matches your service lines, billing models, and project structures A system that fits your business reduces workarounds and manual patches later
Implementation Approach Structured, agile, or hybrid rollout, and how much internal time it requires Determines how fast your firm gets to value and how much disruption to expect
Cost of Ownership License, implementation, training, and ongoing support costs together Total cost, not sticker price, determines long-term ROI
Customer Service Track Record Vendor's support responsiveness and history with project-based consulting firms A vendor's support quality shapes your day-to-day experience for years

Examine each system's track record. The right solution should have a history of successful implementations, ideally with deep experience in the consulting industry. Weigh its technical requirements against your team's current capabilities to gauge how steep the learning curve will be.

Ultimately, the deciding factor should be long-term return on investment. A system that costs more upfront but fits how your firm delivers projects will outperform a cheaper, generic tool over time.

"Any time you switch something that's so ingrained into the everyday of what your employees are doing, it's inevitably going to be a shot in the arm. With the switch to a newer ERP system came a new retooling of how we wanted to do our data collection—we made some amazing advances that have allowed us to double in size in the last six years."

— Katie Wendt, Chief Information Officer, Environmental Works, Inc.

#2 Choose the Right Software Partner

Once upon a time, software was something a company bought and used, end of story.

That was before cloud computing and SaaS (Software as a Service) became the industry standard. Software is now almost a living thing, with frequent updates and upgrades provided as part of the package, which is why choosing the right ERP partner is more important than ever.

During the selection process, you will evaluate features and functionality, but you should also spend at least as much time evaluating the companies that provide these solutions.

Look at their websites to get a sense of their culture, read the blogs and articles they publish, and sign up for a webcast or event if you can. The aim is to gain a genuine, deep understanding of what this company is putting out into the world: do they demonstrate thought leadership, and do they understand your industry and your pain points?

Choosing a software partner that you're aligned with will pay off as you scale and grow in sync with the developments they build into their solutions. When you make the best selection, you and your ERP partner grow together.

Frequently Asked Questions

Basic accounting software tracks income and expenses at the company level, without connecting them to a specific project or client engagement. Project-based ERP ties every transaction, time, expenses, and invoices, to a project, so firms can see profitability and utilization by engagement, not just company-wide totals. That visibility is what most consulting firms are missing when they outgrow spreadsheets or entry-level accounting tools.

Building a custom ERP is technically possible, but it's rarely practical for a consulting firm. Custom builds take significant time and internal IT investment, and they still need ongoing maintenance, security updates, and support that established ERP vendors provide as part of the product. Most consulting firms get a faster return by selecting and configuring an established, project-based ERP instead of building one from scratch.

The right ERP for a consulting firm depends on firm size, service lines, and whether the business needs project accounting or just general bookkeeping. On-premises, cloud, hybrid, and project-based ERP are the four broad categories to evaluate. Deltek is a project-based ERP purpose-built for architecture, engineering, and consulting firms, built to manage the full project lifecycle from pursuit to closeout.

Implementation timelines vary based on firm size, data complexity, and how many integrations are involved. Consulting firms report smoother rollouts when they clean up their data in advance and lean on their vendor's implementation team or partner for support. Ask your ERP vendor for a realistic timeline based on your firm's size and complexity before you sign a contract.

A comprehensive ERP selection checklist compares business-process fit, implementation approach, total cost of ownership, and the vendor's track record with project-based consulting firms. It's also worth weighing the vendor as a long-term partner, not just a software purchase to ensure your ERP system supports your business over the long term. Firms that skip this step often end up forcing a generic tool to fit a project-based business, which rarely works well.

Yes, when the ERP is sized to the firm's complexity rather than built for enterprise-scale operations. Consulting firm Environmental Works, for example, saw an 8% increase in project profitability after moving to a project-based ERP, even while scaling from 150 to over 300 employees. For firms managing multiple simultaneous projects, the visibility an ERP provides typically outweighs the switching cost.[
