What Automotive IT Companies Do

ERP Implementation and Support (SAP Automotive, Oracle, Infor)

Automotive manufacturing requires ERP systems configured for industry-specific processes: production planning with MRP/MPS for JIT and JIS delivery sequences, variant configuration for high-mix assembly (a single vehicle platform can have millions of valid configurations), automotive-specific costing (standard cost, actual cost, Automotive Product Costing in SAP), and PPAP (Production Part Approval Process) record management. Leading platforms include SAP S/4HANA with Automotive Industry Solution (formerly IS-Auto), Oracle Cloud Manufacturing, and Infor LN (formerly BAAN, strong in Tier 2 automotive). IT providers handle implementation, migration from legacy BAAN/SAP ECC 6.0 systems (SAP ECC end-of-mainstream maintenance in 2027), and ongoing AMS (Application Managed Services).

Automotive EDI and Supply Chain Integration

Automotive EDI is among the most complex in any industry, covering ANSI X12 and EDIFACT transaction sets including 830 (planning schedules), 862 (shipping schedules/JIT releases), 856 (advance ship notice), 810 (invoice), and 820 (payment remittance). OEM-specific requirements from GM (GMSQ1000), Ford (Q1 / IATF), FCA/Stellantis (AIAG), and Toyota (TPS-aligned processes) add further complexity. IT providers configure EDI translation software (OpenText TN, IBM Sterling B2B Integrator, DiCentral, SPS Commerce), manage VAN (Value Added Network) relationships, and build middleware integrations with ERP and WMS systems. They also support customer portals like GM Supplier Portal, Ford Covisint/Exostar, and the Stellantis eSupplier portal.

IATF 16949 and APQP IT Systems

IATF 16949 certification requires documented, controlled processes supported by IT systems that provide traceability, calibration management, SPC (Statistical Process Control) data, and PPAP document control. Automotive IT companies implement QMS platforms (ETQ Reliance, IsoMetrix, Intelex, or SAP QM) configured for FMEA (AIAG/VDA FMEA 1st edition, 2019), control plan management, MSA (Measurement System Analysis), and customer-specific requirements (CSRs) from each OEM. SPC software (InfinityQS ProFicient, SPC for Excel, DataLyzer) captures real-time process data from CMMs, gauges, and production equipment for Cpk/Ppk tracking.

Vehicle Telematics and OBD Data Integration

Fleet operators, dealership groups, and automotive technology companies require IT infrastructure to collect, store, and analyze OBD-II (On-Board Diagnostics) and CAN bus data from connected vehicles. IT providers build data pipelines from telematics control units (TCUs) and OBD dongles (Geotab, Samsara, Verizon Connect hardware) through cellular or V2X communication networks into cloud-based fleet management platforms. They also develop integrations with dealer DMS systems (CDK Global, Reynolds and Reynolds, DealerSocket) for warranty repair order correlation and recall campaign management. For automotive OEMs building connected vehicle platforms, IT companies architect MQTT/AMQP broker infrastructure (AWS IoT Core, Azure IoT Hub) to handle millions of simultaneous vehicle connections.

Electric Vehicle Software and Charging Infrastructure IT

The EV transition has created new IT requirements that traditional automotive IT firms are rapidly developing: Battery Management System (BMS) data integration for SoH (State of Health) and SoC (State of Charge) analytics, OCPP (Open Charge Point Protocol 1.6/2.0.1) compliant EV charging network management software, V2G (Vehicle-to-Grid) integration APIs, and over-the-air (OTA) update orchestration platforms for vehicle software stacks. IT providers support OEMs and charging network operators (ChargePoint, Blink, EVgo) with CSMS (Charging Station Management System) implementation, ISO 15118 smart charging protocol integration, and cloud-based energy management dashboards.

Manufacturing IT and Industry 4.0 Integration

Automotive plants are deploying Industry 4.0 technologies - machine learning-based predictive maintenance, cobots (Universal Robots UR series), automated optical inspection (AOI) systems, and digital twin platforms (Siemens Tecnomatix Plant Simulation, NVIDIA Omniverse). IT companies integrate these systems with plant floor historians (OSIsoft PI System, now AVEVA PI), MES platforms (Siemens Opcenter, Rockwell FactoryTalk), and ERP backends. They also manage the OT/IT convergence challenge - securing Ethernet-connected PLCs (Siemens S7-1500, Allen-Bradley CompactLogix) and SCADA systems without disrupting sub-millisecond control loops that automotive stamping and welding operations require.

How to Choose an Automotive IT Company

Automotive is one of the most demanding IT environments - choose a partner who genuinely understands the industry, not one who treats you as a generic manufacturing client:

• Verify IATF 16949 and APQP knowledge: Ask whether their team understands PPAP submission levels, AIAG/VDA FMEA methodology, customer-specific requirements (Ford Q1, GM BIQS, Stellantis SQ), and how QMS software must be configured to support third-party IATF audit evidence. Generic ISO 9001 experience is not sufficient.
• Assess automotive EDI depth: Request references from clients who send JIT 862 shipping schedules to at least two major OEMs. Ask about their experience handling the unique Odette/VDA message standards used by European OEMs (BMW, Mercedes, VW) in addition to ANSI X12 for North American OEMs.
• Evaluate SAP Automotive or Oracle MFG certification: For ERP engagements, look for SAP Recognized Expertise in Manufacturing or Automotive, or Oracle Certified Implementation Partner credentials. Ask for case studies from suppliers with comparable revenue and product complexity.
• Check OT/IT security experience: Automotive plants are increasingly targeted by ransomware (Toyota's 2022 supplier attack shut down 14 plants for one day). Providers should demonstrate experience with OT network segmentation using Purdue Model or ISA/IEC 62443 frameworks, not just standard IT cybersecurity.
• Confirm 24/7 support for production-critical systems: Automotive plants run three shifts, 5-6 days/week. EDI, ERP, and MES outages at any hour are production emergencies. Verify your provider offers a genuine after-hours NOC with automotive-experienced engineers, not just an answering service that escalates to on-call staff.
• Ask about EV and software-defined vehicle experience: If your business is evolving toward EV components, power electronics, or vehicle software, prioritize providers who have begun building competency in OTA update platforms, ISO 15118, and automotive-grade DevSecOps pipelines (ASPICE compliance, functional safety IT for ISO 26262 workflows).
