What shops here make and for whom
The three clusters behave very differently. RV suppliers work on high-volume, schedule-driven programs with model-year changes and tight delivery windows. Orthopedic suppliers handle small lots of validated, fully traceable parts. Automotive and aerospace suppliers work to long-term agreements with detailed quality documentation.
A shop that serves more than one cluster has to maintain different quality systems, documentation and inspection routines inside one ERP.
Quoting and estimating realities
RV suppliers often quote against annual volumes and price lists that change with material cost and model-year updates, so quote history and price tables matter. Orthopedic quotes must include validation, finishing, cleaning and inspection. Aerospace quotes must reflect special processes and long lead items.
A common problem is that the estimate lives in one place and the as-built cost in another, so margins on repeat work drift unnoticed. Comparing quoted and actual cost by part family is a practical first step.
- Tie quoted volumes to actual releases and shipments
- Include validation and inspection time on regulated parts
- Review price lists after material cost changes

ERP and systems commonly seen
Indiana suppliers run a wide range, including JobBOSS, E2, Global Shop Solutions, ProShop, Epicor Kinetic, Infor SyteLine/CloudSuite Industrial, Plex, DELMIAworks, NetSuite and SAP. RV-side suppliers lean on EDI and releases from large builders, while orthopedic shops often add an eQMS for document control and CAPA.
EDI schedule changes, revision control and lot traceability are the usual stress points. When these live in different tools, planners and quality staff spend time reconciling instead of acting.
Compliance, data and where private AI helps
Orthopedic and aerospace suppliers handle confidential designs and, in some cases, export-controlled technical data. Keeping documents and models on infrastructure the shop controls, with ERP role-based access respected, helps the customer meet its own obligations. Netray does not hold any of these certifications on a customer's behalf.
Private AI helps with ERP questions, searching procedures and supplier quality agreements, and preparing for audits. It adds little where data is poor or where a standard ERP report answers the question. Human approval should remain on any write-back or quality decision.
