Schedules that change faster than the plan

Vehicle makers and tier-one suppliers around Sriperumbudur, Oragadam and the southern corridor rarely send a single purchase order and wait. They issue a schedule for the coming period, revise it as their own production changes and then pull parts through daily or shift-wise call-offs. Some send these through a supplier portal, others by spreadsheet or email. A supplier with several customers ends up maintaining a different rhythm for each.

Generic requirements say something like "the system should manage sales orders." That is not enough. I write requirements that state how a schedule is stored, how each revision is kept alongside the previous one rather than overwriting it, how call-offs consume the schedule and how the gap between scheduled and dispatched quantities is reported. These details decide whether planning can trust the system or keeps its own sheet.

I also capture what happens when a customer pulls more than scheduled at short notice, because that is when overtime, premium freight and expediting costs appear. If those costs are not linked to the customer and the schedule change that caused them, management cannot raise the issue in commercial reviews. The requirement work follows the method on my ERP requirements gathering page, applied to your customers' actual documents.

Retrospective price revisions and supplementary invoices

Many automotive supply agreements link part prices to raw material indices or periodic negotiations. A customer may announce a revised price that applies from an earlier date, after hundreds of parts have already been invoiced at the old price. The supplier then has to work out the difference for every affected dispatch and issue supplementary invoices or credit notes, and the customer has to accept them.

Done in spreadsheets, this exercise is slow and error-prone, and money is often left uncollected because the reconciliation is never finished. An ERP can help, but only if the requirement is explicit: prices held with effective-from dates, the ability to identify every invoice affected by a backdated change, calculation of the difference by part and customer, and a record of which differences have been billed, accepted or disputed.

I describe this flow step by step in the requirements document, including approvals and the reports finance needs. The tax treatment of supplementary invoices and credit notes is a question for your chartered accountant, and the requirement leaves room for whatever document type they confirm. When I later score platforms, this scenario is one of the first I test, because it separates systems that store a price from systems that manage price history.

Debit notes for rejections, shortages and warranty claims

When a customer's incoming inspection or assembly line finds a defective part, the supplier often learns about it through a debit note. Shortages at the customer's receiving dock and warranty returns from the field arrive the same way. Each debit note reduces what the supplier will be paid, and without a structured process many are accepted simply because nobody had time to check them.

The requirements I write treat the debit note as a transaction with its own life. It is linked to the original dispatch, part and production lot where possible. Quality reviews the evidence and decides whether to accept, dispute or replace. Where the defect came from a raw material or a subcontracted process, the cost is passed back to the responsible vendor. Finance sees every open debit note by customer and age, not just the net balance.

This flow touches sales, quality, stores and accounts, which is why it tends to fall between departments in a generic BRD. Writing it as one end-to-end process, with clear owners at each step, is where an independent analyst can add real value. For the general structure of the document, see my ERP BRD consulting page and the India ERP business analyst page for national compliance requirements.

Customer-owned dies, molds and fixtures

Press shops, die casters and plastic molders in Ambattur, Thirumudivakkam and the larger estates often hold tools that belong to their customers. The customer paid for the die or mold, sometimes directly and sometimes through an amortization amount built into the part price. The supplier must keep it, maintain it, report its condition and return it on request.

These tools rarely appear properly in an ERP. They are not the supplier's fixed assets, yet their maintenance, repairs and remaining life matter to production planning and to commercial conversations. The requirement I write covers a tool register with ownership, location and customer, a count of strokes or shots linked to production entries, maintenance and repair history with costs, and alerts as a tool approaches its expected life so a replacement discussion starts in time.

Where amortization is included in the price, I add a requirement to track how much has been recovered against the agreed amount, so the supplier knows when the price should change and can raise it with evidence. Some platforms can model customer-owned tools within their asset or maintenance modules; others need a small custom register. The gap analysis shows which applies to your shortlist before you commit to a vendor.

Workshops that work for Tamil-speaking supervisors

The people who know how schedules, rejections and tools are really handled are often stores in-charges, line supervisors and dispatch clerks who have been with the company for many years. Many are more comfortable explaining their work in Tamil than in English, and a workshop run entirely in formal English can lose exactly the detail that matters.

The engagement runs in English, so I plan sessions to accommodate this. A bilingual manager from your team joins each plant session, supervisors explain in whichever language they prefer and the colleague summarizes for the notes. I ask to see the registers, whiteboards and spreadsheets people actually use, because these reveal workarounds that nobody mentions in a meeting. Each session ends with a short list of statements that the supervisor confirms before they go into the document.

All sessions are remote, which suits plants spread across the city's belts and keeps workshops short enough to fit between shift handovers. The output is a requirements document with numbered, testable statements, process maps for each flow and a decision log. The Chennai ERP overview places this work in the wider context of the city's manufacturing base, and you can get in touch to plan the analysis.
