The selection stakes: Research consistently shows that implementation partner quality is the single largest variable in ERP project outcomes — more important than platform selection, budget size, or project scope. A great partner can rescue a difficult project. A poor partner can destroy a well-resourced one. Selecting your implementation partner deserves as much rigor as any major strategic hire or vendor contract.

How to Structure Your Partner Evaluation

An effective partner evaluation proceeds in three stages: qualification (narrowing from the market to 3–5 candidates), RFP and demonstration (comparing capabilities and approach), and finalist selection (detailed due diligence and reference checks). Most companies rush stages two and three, and make their decision primarily on price and demo quality — both unreliable predictors of project success.

The questions below are organized by evaluation stage. Use them as a framework for your RFP, shortlist interviews, and final negotiations.

Qualification Questions

Use these to create your initial shortlist. Partners who can't answer these credibly don't belong on your shortlist.

Section 1: Experience and Credentials
Q1"How many implementations of [specific ERP platform] have you completed in the last 24 months, and what is the breakdown by company size ($10M–$50M, $50M–$200M, $200M+)?"
Volume and recency of experience at your company size is the most predictive credential. Beware partners who cite cumulative totals across decades — ask for the last two years specifically.
Q2"Which industry verticals do you specialize in, and how many implementations have you completed in [your industry] specifically?"
Industry-specific experience means the partner understands your compliance requirements, chart of accounts structure, and operational workflows without needing to learn them on your project.
Q3"What certifications does your team hold, and how many certified consultants do you currently employ?"
Platform certifications (NetSuite SuiteFoundation, Microsoft MBC, SAP certifications) indicate that consultants have been formally validated. Ask specifically about the proposed team, not the firm's total certified headcount.
Q4"What percentage of your implementations in the last two years went live within 20% of the original budget and timeline?"
Most partners won't give you an honest number voluntarily. Push for specifics. A partner who can't cite a track record of on-time, on-budget delivery is telling you something important.
Q5"Have you ever been hired to rescue or complete an ERP implementation that another partner failed? If so, what went wrong?"
Partners who have seen failures up close understand what causes them — and have strong incentives to avoid them. This question also gives you useful insight into their problem-solving approach.

Project Approach Questions

Use these during the RFP response review and presentation stage to evaluate methodology and team quality.

Section 2: Methodology and Delivery
Q6"Walk me through your standard implementation methodology phase by phase. How does it handle scope change requests?"
Partners with mature methodologies have documented, repeatable processes. Absence of a clear methodology is a red flag. The answer to the scope change question reveals whether change control is a real governance mechanism or a formality.
Q7"Who specifically will be assigned to our project, and what is their individual experience level? Will those people be dedicated to us or split across multiple projects?"
Partner firms sometimes win deals with senior resources and then staff projects with junior consultants. Named resources with specific experience, contractually guaranteed, is the protection you need.
Q8"What is your data migration approach? How many test migration cycles do you include, and when do they occur?"
Data migration is the most common timeline killer. Partners who treat it as a late-stage task or include only one test cycle are underestimating its complexity. You want a partner who starts data profiling early and plans multiple migration cycles.
Q9"How many hours per week will you require from our internal team, and by role? Please provide a resource loading chart."
Partners who can't give you a credible internal resource estimate haven't done rigorous project planning. This is also critical for evaluating whether your team can realistically support the project.
Q10"What is your policy on customization? How do you handle requests to customize the system versus recommending process changes?"
The best partners push back on unnecessary customization and propose process changes instead. Partners who say yes to every customization request are building scope and billing hours — at your expense and timeline risk.
Q11"What does your hypercare support model look like? How long is the hypercare period, and what is the staffing level?"
Go-live is when the real learning begins. Partners who end engagement at go-live or provide minimal hypercare leave companies exposed. You want at least 4–6 weeks of intensive post-go-live support.
Q12"How do you handle integration discovery if we find that a third-party API is more complex than initially scoped?"
Integration surprises are common. You want a partner with a defined process for re-scoping mid-project — not one who either absorbs the cost (creating resentment) or immediately issues a change order for every surprise (creating budget shock).

Commercial and Risk Questions

Section 3: Pricing, Contracts, and Risk
Q13"Is this engagement priced as fixed-fee, time-and-materials, or a hybrid? What triggers additional billing beyond the base quote?"
Time-and-materials contracts transfer all project risk to you. Fixed-fee contracts create a strong incentive for partners to complete scope efficiently. Hybrid models can work if the fixed and variable portions are clearly defined.
Q14"What contingency is built into your estimate, and what scenarios would cause you to trigger a change order?"
Honest partners build contingency into their estimates and are transparent about it. If an estimate has zero contingency, it will be exceeded — and the change order conversation will happen later, under more pressure.
Q15"What are the provisions in your SOW for scope management, timeline delays on the client side, and dispute resolution?"
Read the proposed contract carefully before signing. Provisions that shift timeline risk to the client (e.g., "delays caused by client will extend timeline at the same daily rate") can dramatically increase project cost if your team is slower to respond than planned.
Q16"Do you carry professional liability (E&O) insurance, and what is the coverage limit? Can you provide a certificate?"
For significant ERP projects, professional liability coverage matters. Partners who don't carry E&O insurance may not have the financial capacity to remediate problems they cause.
Q17"What happens if the project lead or key consultant leaves during the engagement? What is your knowledge transfer and continuity policy?"
Consultant turnover is a real risk on long projects. Partners with mature knowledge management practices and documented replacement procedures are more resilient than those who depend entirely on individual expertise.

Reference Check Guide

Reference checks are the highest-value due-diligence activity in partner selection — and the most commonly rushed. A 20-minute reference call is insufficient. Block 45–60 minutes with each reference, and ask for the CFO or project lead, not a marketing-provided testimonial contact.

Questions to Ask Partner References

  1. How did the final project cost compare to the original quote? By how much did it exceed budget, and what drove the overages?
  2. How did the actual go-live date compare to the original target? What caused any delays?
  3. Were the same consultants who were presented during the sales process actually assigned to your project?
  4. How did the partner handle scope change requests? Were change orders transparent and fairly priced?
  5. What was the weakest aspect of the partner's delivery? (Silence or refusal to answer here is itself informative.)
  6. Did the partner push back on inappropriate customization, or did they just build what was requested?
  7. How was the post-go-live hypercare? Were critical issues resolved quickly?
  8. If you had to do it over, would you use this partner again? (The "yes, but..." matters as much as the yes.)

🚩 Red Flags to Watch For

  • Reluctance to provide unfiltered references. If a partner only offers references they've pre-briefed, ask to speak with a reference from a project that had significant challenges. Their response tells you a lot.
  • Aggressive timeline estimates. If the timeline seems unrealistically short given project complexity, it's usually a sign of either inexperience or a deliberate strategy to win the deal and expand later.
  • Heavy use of offshore or subcontracted resources without transparency. Offshore resources can be excellent — but you should know upfront who is delivering the work and how they're managed.
  • No formal change control process. Partners who "handle scope informally" are not protecting your interests. Formal change control is a sign of a mature organization.
  • Principals close the deal but junior staff deliver. If the partner's senior partner or principal is leading your sales process but will have minimal involvement post-contract, factor that into your decision.
  • Unable to produce a detailed project plan. Before signing, ask for a sample project plan from a comparable recent engagement. Partners who can't produce a credible, detailed plan haven't done the pre-sale work that predicts delivery quality.
  • Dismissive of your data quality concerns. Partners who say "data migration is straightforward, we handle it all the time" without asking about your data complexity are either inexperienced or not listening.
  • Vendor-partner relationship incentives that bias advice. Some implementation partners earn significant licensing revenue when clients choose a specific ERP platform. This creates conflicts of interest. Ask partners directly whether they receive referral fees from ERP vendors.

Key Contract Terms to Negotiate

Contract TermWhat to Require
Named Resources Specific named consultants, with their CVs attached. Define replacement process and notice period if a named resource leaves.
Change Control Process Written change order process with defined response times, approval requirements, and impact assessment before work begins.
Go-Live Criteria Objective criteria for go/no-go decision — defect thresholds, data validation completion rates, UAT sign-off requirements.
Hypercare Period Minimum 30 days; ideally 60 days post-go-live. Define staffing level and response time SLAs during hypercare.
Escalation Process Named escalation contacts on both sides. Defined response timeframes for critical issues (P1: 4 hours, P2: 1 business day, etc.).
Intellectual Property Any custom development created for your project belongs to you, or is licensed to you in perpetuity. No restrictions on future partners using the configuration.
Payment Schedule Milestone-based payments tied to delivery of specific deliverables — not time-based. Avoid large upfront payments that reduce partner accountability.
Dispute Resolution Defined mediation step before arbitration or litigation. Include a process for engaging a neutral third party to assess disputed deliverable quality.

Where to Find ERP Implementation Partners

The traditional path to finding implementation partners — asking the ERP vendor for referrals — has a conflict of interest built in. Vendors refer their preferred partners, not necessarily the best fit for your requirements. Additional sourcing approaches include:

Regardless of where you source candidates, run every finalist through the full evaluation process above. Source quality doesn't substitute for due diligence.
