ERP Guides — the editorial guides for US mid-market buyers
The editorial guides on erp-software.org cover the questions that US mid-market buyers actually face during an ERP project — selection, cost, migration, implementation, cloud-versus-on-premises, requirements documents, vendor RFPs. Each guide is independent of any specific product, written for practitioners and updated on a published cadence. This index lists the available guides and the order in which they typically become relevant during a project.
Foundational guides
- What is an ERP system — the definition, the modules, the role in the operational stack
- ERP systems overview — the comprehensive landscape of products, deployment models and vendor categories
- Cloud ERP vs on-premises — the deployment-model trade-off in detail
- Cloud ERP — public, private, hosted and hybrid cloud patterns with the data-residency and compliance concerns that matter to US buyers
Selection and procurement
- ERP selection — the end-to-end selection process for mid-market buyers
- ERP RFP process — the structured tender mechanics
- ERP requirements document — the template and the chapter-by-chapter guidance
- Requirements document example — a concrete worked example with MoSCoW prioritization
- Compare ERP systems — the methodology for structured comparison
- ERP cost overview — the cost components and realistic benchmarks
Migration and implementation
- ERP migration — strategies, phases, risks and the data-migration discipline
- SAP ECC to S/4HANA migration — greenfield, brownfield and selective data transition paths
- ERP implementation — the project phases, partner selection, change management and hypercare
Topic guides
- ERP news — market developments shaping 2026 buyer decisions

How we build these guides
Each guide on erp-software.org is structured around a specific decision a US mid-market company is likely to face: when to migrate, which vendor short-list fits the size of the operation, how to scope an RFP, what to expect during go-live week, how to model 5-year TCO with realistic add-on and implementation-service cost. We start every guide from public sources (vendor documentation, analyst reports from firms such as Gartner, Forrester, IDC and Panorama Consulting, and official US government publications such as the U.S. Census Bureau, Bureau of Labor Statistics and NIST) and cross-check against interviews with ERP consultants who run mid-market projects in the United States.
The editorial discipline: no paid placement, no "the best ERP" verdicts, no affiliate-revenue links. Where we name vendors we give the trade-off explicitly — choose X if your operation matches profile Y, choose Z if it matches profile W. This pattern produces guides that are usable as actual planning artifacts rather than as marketing-funnel content.
How to get the most out of these guides
For first-time ERP buyers in the US mid-market, the recommended reading order is: ERP System Definition first (concept primer), then ERP RFP Process to understand the structured selection methodology, then ERP Cost Overview to set realistic budget expectations, then ERP Implementation for what happens after signing.
For experienced project leads running a migration, jump straight to First-90-Days Checklist and Data Migration Guide — these are the two areas where mid-market projects most consistently underestimate effort. For SAP customers facing the 2027/2030 maintenance cliff, the dedicated SAP ECC to S/4HANA Migration playbook covers the brownfield-vs-greenfield decision in detail.
