Frequently Asked Questions

Questions About ERP Selection Advisory

Common questions organizations ask before hiring an independent ERP selection consultant.

What is ERP selection advisory?

ERP selection advisory is a service that helps organizations build a structured process to evaluate and choose the ERP system that best fits their needs – instead of researching on their own, sitting through vendor demos, and deciding on gut feel. An independent consultant sets objective evaluation criteria, runs demos against real business scenarios, and delivers a data-driven recommendation, free from any vendor relationship.

Who leads ERP selection projects at S4?

Phạm Hoàng Lạc, CEO of S4 Consulting, personally leads S4’s ERP selection projects. He has advised a range of major Vietnamese organizations, including SSI Security, PetroVietnam Technical Services Corporation (PTSC), Vissan, the University of Medicine and Pharmacy, and Hanoi Beer Alcohol and Beverage Corporation (Habeco).

When should an organization hire an ERP selection consultant?

It’s worth considering independent advisory when you’re choosing between multiple ERP vendors, when several departments have conflicting requirements that need to be reconciled, or when leadership needs a decision process that can be defended to a board or shareholders – as was the case for SSI Security in selecting its future management system.

How is independent ERP selection advisory different from advice from an ERP vendor?

An ERP vendor is always incentivized to sell its own solution. An independent consultant like S4 Consulting takes no commission from any vendor, so evaluation criteria and scoring weights are built around your organization’s actual needs rather than favoring a particular solution.

What does S4’s ERP selection process look like?

S4 applies its Fast & Saving methodology across 3 sequential workstreams: (1) building the RFP, evaluation criteria, and a weighted scoring framework, (2) vendor bidding – reviewing proposals, running demos, and assessing each vendor’s implementation team, and (3) consolidating scores, analyzing risk, and building the final selection recommendation.

How long does an ERP selection engagement take?

Timeline depends on company size and the number of vendors being evaluated. As a reference point, S4’s ERP selection project for SSI Security ran about 2 months, from building the RFP through the final recommendation.

How much does ERP selection advisory cost?

Cost depends on project scope, the number of workstreams, and how many vendors need to be evaluated. S4 uses a transparent Time & Materials model, with a specific quote provided after an initial scoping conversation.

Does S4 help with implementation after the ERP is selected?

Yes. S4 Consulting is an implementation partner for Oracle NetSuite and Acumatica, so after the selection phase it can continue on as the implementation partner for the chosen system, or hand over the full evaluation record to whichever implementer the organization selects.
