Spare-Parts Enquiries: Answer After-Sales Requests Without Delays

Set up a spare-parts and after-sales enquiry flow that identifies the machine, quotes the right part and commits a date within hours.

In short
Most delay comes from identifying the machine and part, not from quoting the price.
Capture serial number, photo and symptom on the first message, then look up the bill of materials.
Quote from live stock with a committed dispatch date, and track every enquiry to closure.
The problem

A customer's line is down. They send a WhatsApp photo of a worn bearing and a vague model name. Sales forwards it to service, service asks stores, stores asks for the part number, and the customer waits two days for a price. By then they have called a local trader who promised something the same afternoon.

After-sales is often the most profitable revenue a manufacturer has, yet it runs on personal phones and memory. Nobody owns the enquiry end to end. The same customer gets different answers from different people, and the plant head only hears about it when an angry email reaches the managing director.

Why it happens
01The machine serial number and installed configuration are not captured or easy to look up.
02Part numbers live in drawings and old bills of materials that only a few engineers can read.
03Stock and lead times sit in Tally or the ERP, separate from where enquiries arrive.
04No single owner or timer per enquiry, so requests stall between sales, service and stores.
How to fix it
1
Fix the intake fields
Ask every enquiry for serial number, model, photo of the nameplate and part, symptom and site location. Use one short WhatsApp or web form so nothing is missing.
2
Map serials to bills
Link each machine serial to its as-built bill of materials and drawing revision, so the right part number is found in minutes instead of by asking a senior engineer.
3
Quote from live stock
Check stock, reserved quantity and supplier lead time in Tally or the ERP before quoting. Send price, GST, dispatch date and validity in one standard quotation.
4
Own and close tickets
Give each enquiry one owner and a response target you define. Track it through quote, purchase order, dispatch and e-way bill, then confirm receipt with the customer.
Where an AI agent helps
Input

Agent does
Reads the nameplate, finds the bill of materials, checks stock and lead time, drafts the quotation
Human gate
Service engineer confirms part number; sales approves price and dispatch date
Outcome
Accurate quote sent same day, ticket tracked to dispatch
What to measure

Questions
What is the single biggest fix for slow spare-parts quotes?

Capture the machine serial number and a nameplate photo on the first message. Once you can tie the enquiry to the machine's bill of materials, most of the back-and-forth between sales, service and stores disappears.

Should we publish spare-parts prices to customers?

For fast-moving consumables, a published price list or portal often helps. For engineered parts with variable lead times, quote individually but use a standard template so price, GST, dispatch date and validity are always clear.

How do we handle old machines with missing drawings?

Start a reverse-engineering log. When an engineer identifies a part for an old machine, record the part number, photo and dimensions against that serial. Over time the gaps close and fewer enquiries need a senior engineer.
