Choosing an ERP at a Large Enterprise: It’s Not Just a Technology Decision

At large enterprises, ERP selection is never just about picking software – it’s a decision that shapes how the whole organization runs for years to come. Here are the real challenges and lessons S4 Consulting has learned from advising large enterprises through their ERP selection process.

3 Common Challenges

The larger the organization, the more the ERP selection process runs into roadblocks that have nothing to do with technology.

01

High Stakes, Every Department Involved

An ERP decision touches finance, sales, manufacturing, and operations all at once. Building consensus requires a selection process where every department head has a real voice, not just one team calling the shots.

02

Proposals Are Getting Harder to Evaluate at Face Value

AI has made vendor proposals more polished and detailed than ever, which makes it harder than ever to tell a genuinely strong solution from one that just reads well on paper.

03

Not Enough In-House Expertise to Vet the Consulting Team

Most organizations simply don’t have the technical depth to accurately judge the real capability of the consultants who will actually be running the implementation.

Our Approach: A Structured Selection Process

Three principles S4 applies to help large enterprises make an ERP decision that’s objective and on schedule.

1

Start With a Clear Methodology Fast & Saving

An effective selection process starts with a clear methodology. That’s why S4 built Fast & Saving – a framework that helps enterprises shorten decision time while keeping the process objective and cost-efficient.

2

Require Proof Through Visuals, Not Just Text

Instead of accepting long written descriptions that AI can easily polish up, S4 requires vendors to demonstrate their solution through screenshots, visuals, and live demos directly in the proposal.

3

Interview the Actual Consulting Team

Real capability lives with the people doing the implementation, not the company’s general credentials. A direct interview with the exact consultants who will work on the project is a non-negotiable step.

Frequently Asked Questions About ERP Selection Advisory

The most common questions enterprises ask when considering an ERP selection advisory service.

What is ERP selection advisory?

ERP selection advisory is a service that helps enterprises build a structured process for evaluating and choosing the right ERP platform and implementation partner, based on objective criteria rather than gut feel or a polished proposal alone. S4 Consulting acts as an independent advisor, with no bias toward any particular vendor throughout the process.

When does a business need ERP selection advisory?

It’s worth considering when the decision spans multiple departments, involves a significant budget, or when the internal team doesn’t have enough technical depth to evaluate ERP vendors’ real capabilities. It’s also a critical step to take before issuing an RFP, to avoid locking in the wrong platform from the start.

What does S4’s ERP selection process look like?

The process runs through 3 sequential workstreams: building the RFP/RFQ and a scoring framework aligned to the business’s real priorities, running vendor evaluations through standardized demo scenarios, and compiling a final recommendation based on transparent scoring data.

How is ERP selection advisory different from ERP implementation consulting?

Selection advisory happens before any contract is signed, focused on choosing the right platform and the right implementation partner. Implementation consulting happens after that choice is made, focused on system configuration, data migration, and go-live. Many businesses skip a structured selection phase and end up paying for it with a poorly matched implementation.

How is ERP selection advisory priced?

Pricing depends on the size of the business, how many departments are involved in the evaluation, and how many vendors need to be assessed. S4 Consulting works directly with each client to scope a quote that fits the specific project.

How long does an ERP selection advisory project take?

Depending on scope, an ERP selection advisory project typically takes 2 to 3 months, from building the RFP through to a final recommendation. The SSI Securities project, for example, was completed in about 2 months, on the committed timeline.
