ERP Vendor Selection Checklist

Why ERP Vendor Selection Deserves More Rigor Than It Usually Gets

Most ERP vendor selections are decided on demos. A slick interface, a confident sales team, and a feature list that checks every box on a hastily assembled requirements sheet. Six months into implementation, the gaps show up — the vendor cannot support multi-entity consolidation, the total cost of ownership is triple what was quoted, or the platform simply cannot scale as the company adds headcount and acquisitions.

A successful ERP vendor selection requires evaluating software capabilities, vendor viability, and total cost of ownership against your specific operational bottlenecks — not against a generic feature matrix. This checklist from ERP For Private Equity walks through the three areas that determine whether a vendor selection holds up over the life of your investment.

Part 1: Software Capabilities

Start With Your Bottlenecks, Not Their Features

Before evaluating any vendor, document the specific operational bottlenecks costing you time or money today — a slow month-end close, manual intercompany eliminations, no real-time inventory visibility, disconnected systems that require duplicate data entry. Score each vendor against these bottlenecks directly, rather than against a generic capability checklist that treats every feature as equally important.

Core Functional Fit

Assess each vendor against your core requirements: financial management, multi-entity and intercompany accounting, inventory and operations management, reporting and business intelligence, and any industry-specific functionality your business requires. Flag any area where the vendor requires custom development to meet a standard requirement — custom code is where implementation timelines and budgets go to die.

Scalability

The system you select needs to support the business you will be in three years, not just the business you are today. If your PE sponsor has an active acquisition strategy, evaluate how easily the platform onboards new entities, whether pricing scales predictably with users and transaction volume, and whether the data model supports the multi-entity complexity that comes with each add-on acquisition.

Part 2: Vendor Viability

Financial Stability and Market Position

You are not just buying software — you are entering a multi-year relationship. Assess the vendor's financial stability, market tenure, customer base size, and investment in ongoing product development. A vendor that is losing market share or has been acquired recently carries real risk to your implementation and your long-term support.

Implementation Partner Quality

The software vendor and the implementation partner are two separate decisions, and the partner has more influence over your outcome than the software itself. Evaluate the partner's industry experience, references from other PE-backed portfolio companies, average implementation timeline, and what their process looks like when something goes wrong mid-project.

Support and Long-Term Roadmap

Ask what support looks like after go-live — response times, escalation paths, and whether support is included or billed separately. Ask about the product roadmap and how often the platform ships meaningful updates. A stagnant product roadmap is a signal the vendor is not reinvesting in the platform you are about to depend on.

Part 3: Total Cost of Ownership

Look Beyond the License Quote

License or subscription cost is rarely the largest component of total cost of ownership. Build a full cost model that includes implementation fees, data migration, integration development, training, ongoing support and maintenance, and the internal staff time required to get to go-live. The vendor with the lowest license quote frequently has the highest true cost once these are included.

Pricing Model Fit

Per-user pricing models can become expensive quickly as a portfolio company scales headcount or adds entities through acquisition. Consumption-based or transaction-based pricing models often deliver more predictable total cost of ownership for PE-backed companies with active growth plans. Model your cost projection three years out, not just for year one.

Cost of a Failed or Delayed Implementation

Factor in the cost of implementation risk itself. Industry estimates put ERP implementation failure or significant overrun rates at 50 to 75 percent when measured against original timeline and budget. A vendor and partner combination with a strong track record of on-time, on-budget go-lives reduces this risk materially — and that risk reduction has real financial value even though it will not appear on the vendor's price sheet.

How to Use This Checklist

Work through all three sections with your CFO, operations lead, and PE deal team before engaging vendors in detailed demos. Score your shortlist against your documented bottlenecks first, then layer in vendor viability and total cost of ownership. The result should be a decision you can defend to your investment committee — and a platform that still fits the business you will be running after your next acquisition closes.
