Take the part back. Check the invoice. Tag it with a return number, match it to the supplier’s purchase, and file the claim before the window closes. Keep the part on a labelled shelf while the supplier decides. When the credit note comes, close the return against it and write off the stock line.
Step one: receive the part at one counter
Every return enters through a single desk. A mechanic who hands a faulty alternator or starter motor to whoever stands nearest has just created a part with no history, no owner and no credit.
Find the sale by phone number or registration plate. Note the sale date, the fitting date if known, the odometer reading at fitting and the kilometres run since then. Write the complaint in the customer’s words. A squeal, a leak and a dead cell each point to a different supplier question.
Do not argue about cause at the counter. Accept the part. Tag it. Explain what happens next.
Step two: inspect and sort the return
A senior person examines the part. Look for impact marks, heat discolouring, bent terminals, missing packaging, stripped threads and any sign that someone has opened the part on a bench. Photograph the part beside its box label.
Then sort it into one of three outcomes. A true defect becomes a supplier warranty claim. Your own error becomes an exchange. Misuse becomes a refusal with the reason written down.
A wrong-part sale, such as a clutch plate for the wrong variant, is your cost. Absorb it. A supplier will only reject it.
- Customer, vehicle and complaint noted
- Part number, batch code and brand read from the label
- Photos of the part, box and any damage
- Outcome: claim, exchange or refusal, with reason
Step three: match it to the supplier purchase
The claim needs the supplier’s invoice. Trace the batch code to the purchase entry. Many shops buy the same brake pad from two wholesalers, and only the batch code on the box shows which wholesaler owes you the credit.
Check the supplier’s claim rules. Some want the claim form and the part back at their warehouse before a fixed cutoff. Others issue a credit note only against a claim number that they hand you after a phone call with their warranty desk.
Write the deadline on the return tag the same day. A late claim is a part you pay for twice. Never skip this step.
Step four: file, chase and hold the part
Send the claim with the invoice copy, photos and complaint. Keep the supplier’s reference on your return record.
Store the part in a labelled bin. Tag it. Lock it. Never put it back on the shelf, even if it looks fine, because a returned battery or sensor can reach the next buyer.
Review open claims every Monday. Anything unanswered past the supplier’s stated time gets a call, with the claim reference and the batch code in front of you.
- Claim form with supplier’s reference number
- Supplier invoice copy and batch code
- Photos and customer complaint
- Collection date or courier receipt
Step five: close the return against credit
Match each credit note to the return and to the original purchase. A short credit or a rejection needs a reason recorded. Short notes beat long memories.
Then settle with the customer by refund, exchange or goodwill. Then fix the stock.
Review rejections monthly. A wholesaler who rejects ignition coils, shock absorbers and wiper motors again and again is a wholesaler to replace. Chase one open claim today. Start with the oldest.

How long do suppliers allow for warranty claims?
It varies by supplier and part type. Read each supplier’s written terms. Put the deadline on the tag.
Should we accept a return without the original invoice?
You can. Look up the sale first. A part you did not sell should be refused, since the supplier will reject it as well and you will carry the loss.
What do we do with electrical parts that fail on testing?
Many suppliers refuse electrical parts that were fitted wrongly. Test it on a bench, photograph the reading and attach it to the claim.
Can software track supplier deadlines?
Yes. A dealer system links each return to the purchase entry, stores the deadline and lists claims close to expiry so nobody relies on memory.
