How Can a Locksmith Keep Track of Faulty Parts Sent Back to the Wholesaler and the Credits Owed?

Locksmiths replace failed gearboxes and cylinders for free, then never see the wholesaler credit. We build a log linking each callback, the part and its credit.

Quick answer — TL;DR

When a new mechanism or cylinder fails soon after fitting, the locksmith replaces it at their own cost and sends the faulty part back, then rarely checks that the credit arrived. Returns sit in the van, labels go missing and credits are forgotten. We build a returns log that starts on the job, tracks each part back to the supplier and matches the credit note in your accounts.

A box of faulty parts in the back of the van

A customer calls because a gearbox your engineer fitted a month ago has failed. The engineer goes back, fits another at no charge and puts the faulty one in a box in the van, with a note that says "return". The box also holds a cylinder with a stiff cam, a handle with a broken spring and something nobody can identify.

Some of these are eventually taken to the wholesaler's counter. The counter staff take them and say the credit will come through. It might. Nobody at your end checks, because nobody wrote down what was returned, when, or against which original invoice. At the end of the year the box is still half full.

Returns fall between the job and the accounts

A faulty part return involves the engineer, the original job, the new job, the wholesaler and the accounts. None of them owns the process from start to finish.

  • The original purchase invoice for the part is not linked to the job it was fitted on.
  • The engineer records the free return visit, if at all, as a job with no charge.
  • Faulty parts are not labelled with job, date or fault.
  • Returns to the wholesaler have no reference your office can track.
  • Credit notes arrive in the accounts without anyone matching them to a return.

Paying twice for the same part

Each unreturned or uncredited part means your business has paid for two parts and been paid for one, plus the free return visit. Individually small, these add up over a year, and nobody sees the total because it is scattered. You also lose useful information: which products or suppliers keep failing.

A returns log that closes the loop

We build a simple returns process linked to your job records and accounting software.

  1. When an engineer attends a failed part, they mark the job as a warranty return visit and pick the faulty part and the original job from the property's history.
  2. The system looks up the original purchase from your supplier invoices where they are linked, or asks the office to confirm it.
  3. A returns label is generated with a reference, the part, the fault description, the original job and invoice, to go with the part.
  4. When the part is handed to the supplier, the return is marked as sent, with the supplier's own reference if they give one.
  5. Credit notes from the supplier are matched to open returns in your accounting software, automatically where the reference matches and by the office where it does not.
  6. Returns with no credit after a set time appear on a chase list, and a report shows failures by product and supplier.

Whether a supplier accepts a return is between you and them under their terms. The log makes sure you ask, and notice when the answer never comes.

Credits arrive and the box empties

Faulty parts go back promptly with the information the supplier needs. Credits are matched rather than hoped for. The office can see what is outstanding with each supplier. And after a few months, the failure report shows which products cause the most callbacks, which feeds straight into what you stock.

Engineers stop carrying a mystery box around. The part goes back with its label within the week, the office sees it on the open returns list, and when the credit note lands in Xero or QuickBooks it is matched without anyone hunting for the original invoice. If a credit never comes, the chase list says so while the return is still fresh enough to argue about.

Is this happening in your vans?

  • Faulty parts sit in vans waiting to be returned.
  • Nobody checks whether supplier credits arrive.
  • Free return visits are not linked to the original job.
  • You do not know which products fail most often.
  • Returns are handed over at the counter with no reference.

FAQ

Frequently asked questions

The questions readers ask us after this guide.

Still have a question?

Ask us directly — a senior engineer will get back to you.

Ask about your project

Does the supplier have to change anything?

No. The log works with whatever returns process your wholesaler already has, and records their reference if they give one.

Can it read supplier credit notes automatically?

If credit notes arrive in your accounting software or by email in a consistent format, we can match them. Otherwise the office matches them from a short list.

What if we cannot find the original purchase?

The return can still be logged and sent. The link to the original invoice is helpful but not required.

Is it worth it for a small firm?

It depends on how many returns you make. If it is rare, a simple spreadsheet may be enough, and we would tell you that.
