A customer complaint costs more than the 8D itself. The customer may sort stock, scrap parts, arrange extra deliveries, and then send a debit note or chargeback to recover those costs. What can be charged, and how, depends on your contract, the supplier manual, and the customer’s terms. They differ by customer and sector, so this page gives no typical amounts and no fixed rules. It describes how suppliers commonly track these costs and how the 8D connects to them.
What a complaint can cost
Most chargebacks and debit notes are built from a few cost types. Knowing them helps you check a debit note line by line.
- Sorting and rework: Hours spent sorting stock at your site, in transit, or at the customer. This includes third-party sorting services the customer arranges and charges back.
- Scrap: Parts scrapped by you or by the customer, sometimes including parts they were built into.
- Extra freight: Express replacement deliveries, returns, and special transport to keep the customer’s line running.
- Admin or handling fee: A flat fee per complaint, if the customer’s terms include one.
- Other costs: Line stops, extra inspection, lab tests, travel, or field actions. These vary most and need the clearest evidence.
Your own internal costs count too, even when nobody charges them: engineering time on the 8D, extra inspection, and production lost to sorting.
How to track complaint costs
- Open a cost record on the day the complaint arrives, with the complaint and part number.
- Log sorting hours, scrap counts, and freight as they happen, with dates and who did the work.
- Keep the evidence: sorting reports, scrap tags, freight invoices, and any customer messages about costs.
- Separate costs the customer charges from your internal costs.
- Total it per complaint, so you can compare it with the debit note when it arrives.
The free complaint cost sheet adds up sorting, scrap, freight, third-party containment (CS1/CS2), line stops, warranty or field costs, admin fees and other costs into a debit summary you can copy, print, or download as CSV. It runs in your browser and doesn’t send or store what you enter. It gives an estimate only; your contract decides what is chargeable.
An illustrative example
The figures below are made-up example figures, not typical or real amounts. They only show how a cost summary is built.
| Cost line (example) | Amount (example figure) |
|---|---|
| Sorting: 12 hours × 40 per hour | 480.00 |
| Scrap: 150 parts × 2.50 per part | 375.00 |
| Express replacement delivery | 220.00 |
| Admin fee per complaint | 100.00 |
| Total (example figures) | 1,175.00 |
In this fictional case, the supplier compares the summary with the customer’s debit note. The sorting hours on the debit note are higher than the sorting report shows, so the supplier asks for the report behind them before agreeing.
Checking a chargeback or debit note
- Does each line link to this complaint, part number, and date range?
- Is there evidence for quantities and hours, such as sorting or scrap reports?
- Do the rates match what your terms or agreement say?
- Did sorting continue after your clean point was confirmed? If so, ask why.
- Are any costs counted twice, for example scrap and rework on the same parts?
Raise questions in writing, through the channel the customer uses, and keep a record. For a formal request, see the supplier SCAR 8D checklist.

How a strong 8D limits repeat costs
The 8D can’t undo costs that have already happened. It can limit what follows:
- D3 containment with quantities per location and a clear clean point gives sorting a defined end. See 8D containment actions examples.
- D4 root cause covering both why it happened and why it escaped makes a repeat complaint less likely. See weak D4 root cause examples and the 8D escape point.
- D6 verification with data shows the action works, so containment can end. See D6 verification of effectiveness.
A rejected 8D usually means more rounds, longer containment, and more cost. See 8D rejected: what to do next and, if the due date is close, missed 8D deadline: what to do.

FAQ
- Do I have to accept every debit note?
- That depends on your contract, the supplier manual, and the agreed terms. Check each line against the evidence and the terms, and ask for missing detail before you agree. This page is not legal or contractual advice.
- Does a strong 8D reduce the cost of this complaint?
- Mostly it limits what comes next. Containment with a clear clean point can stop sorting from running longer than needed, and a verified root cause with an effective action lowers the chance of a repeat complaint and the costs that come with it.
- What does 8D Gate check?
- It gives a pre-send readiness check on the 8D text: an Accept / Conditional / Reject advisory with missing evidence and questions. It doesn’t check costs or debit notes, and it isn’t a customer decision. The review tool is v0.1: it reviews English 8D reports, and the interface and report are in English. Templates are also available in German, Czech and Polish.
