How to Choose an ERP Consultant for Sage 100 or Sage 300

The right ERP consultant can make the difference between a smooth implementation and a multi-year headache. Here's what to evaluate before hiring one.

ERP consulting quality varies widely, and the difference often isn't visible until well into a project. Here's what to evaluate up front.

1. Accounting Background, Not Just Technical Configuration

Many ERP issues are accounting questions wearing a software costume — inventory valuation, job costing, intercompany transactions. A consultant with a CPA or accounting background can diagnose these from the right starting point, rather than treating every issue as purely a configuration problem.

2. Relevant Industry Experience

Manufacturing and distribution have different operational realities — BOMs and work orders versus multi-warehouse purchasing and landed cost. Ask for examples of work with businesses similar to yours, not just general ERP experience.

3. Experience With Your Specific Platform Version and Tier

Sage 100 and Sage 300 each have version-specific quirks, and Premium (SQL Server-based) environments have different considerations than Standard or Advanced. A consultant's experience should match your actual environment.

4. Third-Party Integration Experience

If you rely on EDI, payment processing, or other integrations, ask specifically about the consultant's experience with those integrations — particularly during version upgrades, where plugin compatibility is the most common source of issues.

5. Approach to Data Migration

Ask how they approach data migration — do they run migrations in a parallel environment with validation before cutover, or migrate directly into production? The former is significantly lower-risk. See our ERP data migration checklist for what a thorough approach looks like.

6. Ongoing Support Model

Understand what happens after go-live — is ongoing support available, what's the typical response time, and is it the same team that did the implementation (who already understand your configuration) or a different support queue?

7. References and Case Studies

Ask for examples of completed projects with specific, verifiable outcomes — not just general claims of experience. See our case studies page for examples of the kind of detail worth asking for.
