Manufacturing ERP Guide: BOMs, MRP, Shop Floor and Costing
A practical guide to manufacturing ERP: modelling BOMs and routings, making MRP trustworthy, shop-floor data capture, costing, quality and traceability.

Automotive ERP for suppliers, parts businesses and workshops
“Automotive” covers very different businesses: tier-two suppliers shipping to OEM plants on tight schedules, aftermarket distributors with catalogues of tens of thousands of parts, and service workshops managing vehicles, technicians and parts. Each needs a different emphasis from its ERP.

Context
ERP in automotive
What they share is volume, precision and traceability: the right part, in the right quantity, at the right time, with records to prove where it came from.
01Operational challenges
What usually breaks before the ERP project starts
01
OEM schedule volatility
Release schedules change weekly, and suppliers must adjust production without overbuilding.
02
EDI and labelling requirements
Customers mandate EDI releases, advance shipping notices and specific label formats.
03
Fitment data complexity
Aftermarket parts must be matched to make, model, year and engine variants.
04
Workshop parts and labour
Service jobs need parts reserved and technicians scheduled, with warranty claims tracked.
02Core flows
How the ERP should handle each part of the business
- Sales flow
- Suppliers receive blanket orders with releases via EDI; distributors sell by fitment lookup to trade and retail; workshops quote jobs combining parts and labour.
- Procurement
- Components purchased against firm and forecast releases; distributors replenish by demand history and supplier lead times.
- Inventory
- Lot or serial tracking for safety-relevant parts; large SKU counts organised by category and supersession chains.
- Warehouse
- High-volume picking, cross-references between part numbers and customer-specific packaging and labels.
- Manufacturing
- Suppliers run repetitive production against releases with quality checkpoints, PPAP documentation and traceability to material lots.
- Accounting
- Customer-specific pricing and rebates, warranty recoveries and core charges for remanufactured parts.
- CRM
- Fleet and trade accounts, OEM programme management and workshop customer histories by vehicle.
03Industry workflows
Workflows specific to automotive
01
Release management
Incoming EDI releases update planned demand; cumulative quantities reconciled against shipments.
02
Part supersession
Superseded part numbers redirect demand and stock to replacements.
03
Core returns
Core charges billed with remanufactured parts and credited when cores are returned.
04
Warranty claims
Failed parts claimed back to suppliers with documentation from the service job.
04 — Reporting
Reports that should come out of the system, not a spreadsheet
- Release vs shipment cumulative reconciliation
- Fill rate and on-time delivery by customer
- Stock turns by part category
- Warranty claims and recoveries
- Workshop technician utilisation
- Quality PPM by customer
05 — Compliance
Compliance considerations
Automotive suppliers often operate under IATF 16949 with PPAP, control plans and traceability. Distributors may face product safety recall obligations. The ERP should retain lot genealogy, quality records and supplier documentation.
Regulatory requirements vary by jurisdiction. We configure the system to support your obligations; confirm specific rules with your auditor or compliance advisor.
06 — Integrations
Systems the ERP needs to talk to
EDI with OEMs, fitment catalogue data providers, dealer and workshop systems, carrier platforms and marketplaces for aftermarket sales are the main integrations.
07AI opportunities
Where AI is genuinely useful here
Practical uses that sit on top of clean ERP data. None of them replace getting the core transactions right first.
01
Part identification
Match customer descriptions or part numbers from other catalogues to your SKUs.
02
Release change analysis
Highlight significant changes between successive OEM releases for planners.
03
Workshop job drafting
Suggest parts and labour lines from a described fault or service interval.
08ERP modules
Modules a typical deployment includes
- M01Sales & EDI
- M02Manufacturing
- M03Inventory
- M04Purchasing
- M05Quality
- M06Repair / Service
- M07Accounting
- M08Barcode
09Roadmap
Implementation roadmap
- 01
Segment-specific design
Decide whether supplier, distributor or workshop processes are the focus.
- 02
Core flows
Orders, inventory, purchasing and accounting live.
- 03
EDI and fitment
Customer EDI or catalogue data integrated.
- 04
Quality and service
PPAP records, warranty and workshop flows.
10Common mistakes
Mistakes we see repeatedly
01
Manual EDI handling
Re-keying releases defeats the purpose of EDI and causes shipment errors.
02
Ignoring supersessions
Without supersession chains, demand and stock fragment across old and new part numbers.
03
Generic labels
Non-compliant labels can lead to customer chargebacks.
04
Fitment as free text
Unstructured fitment data cannot power accurate search or online sales.

FAQ
Frequently asked questions
Can the ERP handle OEM EDI releases?
Yes, through EDI integration that converts releases into demand and generates advance shipping notices from shipments.
How do we manage fitment data?
Fitment can be stored as structured attributes or linked to a fitment data provider, depending on catalogue size.
Can workshops use the same system?
Yes, with repair or service modules for vehicles, jobs, parts and labour.
