In short
- Licence is usually a minority of true ERP cost across a five year lifecycle.
- Implementation, migration, integration and training routinely exceed the software cost.
- Internal staff time is the most commonly omitted line and one of the largest.
- Automotive adds specific setup costs: schedule mapping, ASN and label formats, PPAP structures and traceability.
Why the licence figure misleads
When a Hosur supplier first evaluates ERP, the conversation anchors on a per user per month figure, because it is printed largest. Across a realistic lifecycle it is frequently a minority share of total spend.
Everything around the software costs more than the software: configuring it to your process, cleaning and migrating item masters and BOMs, connecting it to GST filing and customer portals, training people, and running it afterwards. Total cost of ownership is the discipline of counting all of it before committing.
For an automotive supplier the configuration effort is genuinely higher than for a general business, because schedules, ASN formats, PPAP structures and traceability all need setting up correctly the first time.
Visible cost lines
- Subscription, scaling with users and modules.
- Implementation and configuration, shaping the platform to your schedule-to-dispatch flow.
- Data migration, item masters, BOMs, routings, vendors, customers and opening stock.
- Integration, GST e-invoicing, banking, customer portals and occasionally shop-floor devices.
- Training, initial and ongoing as staff turn over.
- Infrastructure, cloud subscription or on-premise elements.

The hidden lines that break budgets
- Internal staff time. Hours your own people spend in workshops, data cleaning, testing and validation. No invoice, but real cost, and routinely ignored.
- Change management. Moving a floor from paper travellers to a disciplined system, and absorbing the resistance.
- Customisation creep. Small requests that collectively inflate scope.
- Productivity dip at go-live. Output slows for a few weeks. It has a delivery cost.
- Ongoing administration. Someone must own users, reports and upgrades.
- Rework from poor data. Cheap migration of dirty masters is paid for repeatedly.
Automotive-specific cost lines
| Cost line | Why it exists |
|---|---|
| Schedule format mapping | Each OEM sends a different structure that must be mapped once |
| ASN and label configuration | Customer-specific dispatch notice and label layouts |
| PPAP and control plan setup | Quality structures per part number and characteristic |
| Lot traceability configuration | Genealogy from raw lot to dispatched part and ASN |
| Job work reconciliation | Challan flow, vendor WIP and ITC-04 data |
Budget these explicitly rather than discovering them mid-project. See our quality and vendor management pages for what each involves.

A five year shape
| Cost line | Year 1 | Years 2-5 |
|---|---|---|
| Subscription | Medium | Recurring |
| Implementation | High | Low |
| Data migration | Medium | Minimal |
| Integration | Medium | Low to medium |
| Training | Medium | Low but ongoing |
| Internal staff time | High | Low |
| Support | Low | Recurring |
| Automotive setup | High | Low |
Year one is front-loaded with one-off effort; later years settle into a lighter recurring pattern. An option that looks cheap in year one but carries heavy ongoing maintenance often loses over the horizon.
Building your own estimate
- List every line above, visible, hidden and automotive-specific, and mark which apply.
- Estimate internal staff time in hours and value it at loaded cost.
- Project each line across five years, separating one-off from recurring.
- Add contingency for customisation creep.
- Compare options on the five year total, never on licence alone.
Our selection guide sets cost within the wider decision.
Key Takeaways
- Subscription is usually a minority of five year total cost.
- Implementation, migration, integration and training together typically exceed software cost.
- Internal staff time is the most commonly omitted and one of the largest lines.
- Automotive adds schedule mapping, ASN and label setup, PPAP structures and traceability configuration.
- Only a five year view compares options fairly, because year one is front-loaded.
- A configured platform shifts patching, infrastructure and core development onto the vendor.
Frequently Asked Questions
It depends on users, modules and custom work, which is why responsible pricing follows scoping. What is consistent is that licence is usually a minority of the five year total.
For most manufacturing MSMEs it is a minority. Implementation, migration, integration, training, support and internal staff time together usually exceed it.
Internal staff time. The hours your own people spend in workshops, data work and testing are genuine cost even though no invoice is raised.
Because it carries extra configuration for OEM schedule formats, customer ASN and label layouts, PPAP and control plan structures, and lot traceability.
At least five, because approaches front-load or spread cost differently and a year-one quote can hide heavy ongoing maintenance.
Yes, and most Hosur suppliers should. Go live on schedule-to-dispatch, prove a result, then add quality, traceability and analytics in phases.
Scope against a written process, prioritise changes by value, phase the rollout and hold a contingency for changes that will inevitably arise.
Largely, but its quality has recurring consequences. Cheap migration of dirty masters creates errors you pay for repeatedly.
Subscription, support and administration, occasional new integrations, ongoing training and configuration evolution.
Only if your problem is accounting. If schedules, BOMs, quality and job work are the pain, those stay in spreadsheets, which carries its own substantial uncounted cost.
Conclusion
Total cost of ownership is the difference between a budget that holds and one that quietly doubles. For a Hosur auto-component supplier the subscription figure is close to a distraction. The money sits in implementation, migration, integration, training, support and the hidden lines, plus automotive-specific setup for schedules, ASN, PPAP and traceability. Lay it out across five years and the true shape of each option becomes visible before you sign rather than after.
