ERP Vendor Selection Checklist: 10 Questions to Ask Before Buying

Picture this: You’ve spent months demoing ERP systems, negotiating contracts, and rallying your team—only to realize six months post-implementation that the vendor’s “seamless payroll integration” is anything but seamless. Now you’re stuck with a half-baked system, angry employees, and a CFO demanding answers.

Choosing an ERP vendor isn’t like picking a SaaS app. It’s a 10-year marriage—not a casual fling. The wrong choice can cost millions in downtime, rework, and lost productivity. To avoid buyer’s remorse, here are 10 non-negotiable questions to ask every ERP vendor before signing the dotted line.

1. “Can You Handle Our Industry’s Unique Requirements?”

Generic ERPs promise the moon but often fail industry-specific needs.

  • Manufacturing: Ask about shop floor scheduling, WIP tracking, and compliance (e.g., ISO, FDA).
  • Retail: Demand proof of inventory forecasting and multi-channel sales support.

Example: A dairy company learned the hard way when their ERP couldn’t track batch expiration dates, leading to $250K in wasted stock.

Follow-Up: “Show me how three similar clients use your system.”

2. “What’s Included in the Base Price vs. ‘Extras’?”

Vendors love burying costs in fine print. One hospital was quoted $200K upfront—then hit with $80K/year for “mandatory” security updates.

Ask For:

  • A line-item breakdown of licensing, support, and training fees.
  • Clarify if updates, integrations, or API access cost extra.

3. “How Do You Handle Data Migration?”

Data migration is the #1 cause of ERP delays. A logistics company lost six weeks because their vendor underestimated legacy data cleanup.

Key Questions:

  • Do you provide migration tools or consultants?
  • What’s the process for mapping old data to new fields?

Red Flag: “Don’t worry—it’s plug-and-play!” (Spoiler: It never is.)

4. “What’s Your Policy on Customizations?”

Some vendors charge $300/hour for tweaks; others lock you into rigid workflows.

Case Study: A bakery paid $50K to customize recipe scaling in their ERP—only to lose the changes during an update.

Ask:

  • Are customizations preserved during upgrades?
  • What’s the average cost/time for common tweaks?

5. “Can We Speak to Your Longest-Standing Client?”

References matter, but vendors will cherry-pick happy clients. Dig deeper:

  • Request: A reference from a client using the system for 5+ years.
  • Ask Them: “What’s the one thing you’d change about this vendor?”

Fun Fact: A construction firm discovered their vendor’s “24/7 support” didn’t include holidays—after a system crash on New Year’s Eve.

6. “What Happens If We Outgrow the System?”

Your ERP should scale as fast as your business. A tech startup outgrew their ERP in 18 months, forcing a $1.2M migration.

Ask:

  • What’s the maximum user/data volume supported?
  • Is upgrading to a higher tier seamless?

7. “How Do You Handle Security and Compliance?”

A breach in your ERP could mean lawsuits, fines, or bankruptcy.

Must-Ask:

  • Is data encrypted at rest and in transit?
  • Do you comply with GDPR, HIPAA, or CCPA (if applicable)?

Stat Alert: 68% of ERP users report security gaps post-implementation.

8. “What’s Your Average Response Time for Critical Issues?”

A food distributor once waited 72 hours for a vendor to fix a shipping module bug—costing them a key client.

Get It in Writing:

  • SLA (Service Level Agreement) for critical vs. non-urgent tickets.
  • Escalation paths for unresolved issues.

9. “How Often Do You Release Updates?”

Too few updates = stagnant features. Too many = unstable systems.

Ideal Answer:

  • Quarterly updates with advance testing environments.
  • Clear release notes and backward compatibility.

Avoid: Vendors who push untested “innovation” patches.

10. “What’s Your Exit Strategy If We Part Ways?”

Breaking up is hard to do. One retailer spent $140K to extract data from a proprietary ERP after switching vendors.

Ask:

  • Can we export data in standard formats (CSV, SQL)?
  • Is there a transition support period?

Final Tip: Test Drive with Real Scenarios

Before committing, run a mock workflow:

  1. Process a dummy order from start to finish.
  2. Generate a financial report.
  3. Simulate a system crash.

If the vendor hesitates, walk away.
