How to Hire ERP Consultants

What can ERP consulting firms do for your business?
ERP consulting firms guide the entire project, design your processes, and manage change across every department. Here’s what they can do for your company:
1. They significantly improve your chances of success Organizations that engage ERP consultants report an 85% success rate in their implementations.
Consultants bring a structured methodology, independent oversight, and accountability that internal teams, already stretched across their day jobs, rarely have the bandwidth to provide.
2. They protect your ROI The average ROI for an ERP project is 52% , and companies typically see a return on their investment in approximately 2.5 years. But that return doesn't happen automatically.
Among organizations that conducted an ROI analysis before implementation and had been live for over a year, 83% reported meeting their ROI expectations.
ERP consulting companies drive both outcomes by building the business case upfront and keeping the project aligned with it.
3. They deliver measurable operational gains Around 74% of businesses experienced increased productivity and improved efficiency following ERP implementation, and roughly 62% said ERP helped reduce costs, particularly in purchasing and inventory control.
For product-based businesses, 91% of organizations reported optimized inventory levels post-implementation.
4. They keep budgets from spiraling Budget overruns typically stem from underestimating project staffing (38%), expanding initial scope (35%), and technical or data issues (34%).
Consultants manage all three by scoping accurately, controlling scope creep, and flagging data issues before they become expensive mid-project surprises.
How do I know if my organization is actually ready for ERP implementation?
Your organization is ready for ERP implementation when you have executive commitment, clean data, documented processes, and a budget that covers more than just the software license.
Most ERP projects don't fail because of bad software, but because the organization wasn't ready before the project started. An ERP readiness assessment helps you figure out whether now is the right time to implement, and sometimes the honest answer is that it isn't.
Readiness comes down to four things:
People Processes Data Budget
Companies that jump straight to vendor selection without first checking readiness often find themselves mid-project with no internal champion, dirty data, and a budget that covers only half the work.
How do I compare two consultants who claim expertise in the same platform?
When two ERP consulting companies claim expertise in the same platform, what sets them apart is usually their industry experience, team structure, methodology, and how they handle challenges when the project gets hard.
Use this comparison framework:
Criteria What to ask What a strong answer looks like
Industry experience How many projects have you completed in my industry and at my company size? Specific project names, industries, and company sizes, not general claims
Team structure Who will work on my project day to day?
Named individuals with verifiable backgrounds, not just firm credentials
References Can I speak with a past client who has a similar project?
References from companies in your industry at roughly the same size, including clients who may not have had a perfect experience
Methodology Walk me through how you handle scope changes mid-project
A clear, documented process; vague answers here signal trouble later
Cost transparency Give me an itemized estimate, including variable costs
Reliable consultants provide itemized estimates and explain how they structure fees, including variable costs for custom work and ongoing support
Compensation model Do you receive commissions from any software vendors?
A truly objective ERP consulting firm will highlight the pros and cons of multiple solutions without steering you toward what they are most incentivized to recommend
Post go-live support Who supports us after go-live, the same team or different?
Same team or a named handover process, not a generic support desk
The same ERP platform can lead to completely different outcomes depending on who implements it, so the tiebreaker is rarely technical certification. It's track record, transparency, and how well they listen before they start talking.
Do ERP consultants provide support after go-live?
Most ERP consulting firms offer post-go-live support, but the scope, duration, and cost vary significantly. If you don't define it in the contract before signing, you may not get what you expect.
Over 58% of businesses fail to achieve the expected ROI within the first 2 years, primarily due to inadequate post-deployment support.
What the first phase looks like: hypercare Immediately after go-live, a phase known as hypercare begins, focusing on stabilizing the new system and ensuring end users adopt new ways of working. This typically lasts four to six weeks and involves intensive support from both the consulting team and your internal staff.
Eventually, the project team phases out, and a smaller support team takes over, which means slightly longer response times. Managing expectations across your organization in advance is important.
What ongoing support should cover After go-live, skilled ERP consulting firms can help resolve issues and backlogs, standardize processes to prevent workarounds, and fine-tune system performance.
Longer term, good support shifts from fixing problems to continuous improvement, helping the system evolve as your business grows.
What to define in the contract Before signing, get clear answers on these four things:
Who specifically provides support after go-live, the same team or a different one?
What is the response time guarantee, and is it in writing?
Is post go-live support included in the project fee or billed separately?
How long does the consultant remain available after the system goes live?
The most effective ERP support partnerships are built on continuity; a partner who already understands your configuration and culture can step in quickly when new needs emerge, rather than starting from scratch.
What questions should you ask ERP consulting companies before signing a contract?
Ask ERP consulting companies questions across three areas: their background, their process, and their fit for your specific project, to separate the firms that can deliver from the ones that just say they can.
Relevant Background
How many ERP implementations have you completed in our industry, and at our company size?
Can you provide references from two or three past clients with projects similar to ours? Can we speak with them directly, not just read testimonials?
Who will be working on our project day to day, and what are their individual qualifications?
Do you receive any commissions or fees from ERP software vendors, and how does that affect which solutions you recommend?
Services and Processes
What does your implementation methodology look like phase by phase, and what milestones will we be measured against?
How do you handle mid-project changes, and what does that mean for our timeline and budget?
What does post-live support look like? How long does it last, and is it included in the project fee or billed separately?
What happens if the project goes over budget or misses the go-live date — what does the contract say about accountability?
