I have been through two ERP rollouts in manufacturing environments and both of them were painful in ways that felt completely avoidable in hindsight. I always assumed we just got unlucky with vendors or timing. Then I came across an article that broke down the actual reasons this keeps happening across the industry and it made a lot of things click.

The core problems it identifies:

1. Everyone compares feature lists. Every vendor checks every box on every RFP. The spreadsheet tells you nothing because the answer is always yes. What actually eliminates vendors are the hard technical requirements a system simply cannot meet, and nobody leads with those.
2. Most consultants running these evaluations are not independent. Referral arrangements between consultants and vendors are standard practice in this market. The recommendation follows the commission, not your requirements.
3. The demo is not real. Sales teams show you a clean environment with practiced click paths and ideal data. What you see in the demo has almost no relationship to what your actual production data does inside the system six months later.
4. Implementation costs 2 to 5 times the software subscription and almost nobody budgets for it upfront. Manufacturers keep getting blindsided by this.
5. The SAP ECC deadline is pushing manufacturers into rushed S/4HANA migrations without properly evaluating whether it is actually the right system for their operation. A migration off ECC is a full reimplementation. If you are reimplementing anyway, you should be looking at everything.

All of this matches exactly what I saw from the inside. The selection process is where these projects fail, not the go-live.

Curious whether engineers and ops people here recognise this pattern. Please say what sector and company size you are coming from before replying.

Background: I've watched too many mid-market companies waste 4-6 months and $50K+ on ERP selection consultants, only to pick a system that fails during implementation. The industry failure rate is 55-75%, and most failures happen because companies evaluate the wrong systems from day one.

The Problem: Traditional ERP selection is backwards. Companies score 200 features across 10 systems, produce a meaningless average, then pick based on the best demo or brand recognition. Meanwhile, a single missing capability (parallel ledgers for multi-GAAP, native manufacturing execution, on-premise deployment) can kill the entire project 8 months into implementation.

What I Built: A free comparison tool that uses knockout scoring instead. It identifies your 5-10 technical dealbreakers upfront, eliminates systems that can't deliver them natively, then ranks what's left. Same methodology senior ERP consultants use, but automated.

The tool compares 10 ERP products at the product level (not vendor level, because SAP alone has 4 distinct ERPs with completely diffrent capabilities). Takes 10 minutes, generates instant results, zero vendor bias

Key Technical Decisions:

- Product-level comparison instead of vendor-level (S/4HANA Public Cloud vs Private Cloud vs Business Central vs Finance & SCM)
- Knockout criteria tested: multi-GAAP parallel ledgers, deployment model, manufacturing depth, cloud extensibility, multi-entity management, budget ceiling
- No referral fees or vendor partnerships (revenue from optional premium reports only)

What I Learned Building This:

- Companies don't need 200-feature spreadsheets, they need to know what eliminates a system
- The right ERP product matters as much as the right vendor
- Three to four knockouts typically reduce a shortlist from 6+ systems to 2-3 real contenders

Tech Stack: Knockout scoring algorithm, product-level capability mapping for SAP (S/4HANA Public/Private, ByDesign, Business One), Microsoft (D365 F&SCM, Business Central), Oracle (Cloud ERP, NetSuite), Odoo, and IFS.

Current Status: Live and free to use. Built for mid-market (50-2,000 employees), but the methodology works for any company tired of vendor demos and biased consultants.

Happy to answer questions about the knockout methodology, why product-level comparison matters, or how to avoid the most common ERP selection mistakes.

For the community: What's been your experience with ERP selection? Have you seen companies pick the wrong system because they didn't identify dealbreakers early enough?
