Asking a supplier to lower their price gives you one number to argue about, and no basis to argue from.

**Asking them to break that price into its components gives you twenty numbers — and every one you can compare across suppliers becomes a negotiating point.**

**It also surfaces something you would never otherwise see: which parts of your product cost far more than they are worth.**

*Prefer to watch? One hundred and seventy-nine seconds on when to send the breakdown, comparing line items across suppliers, and sourcing a component your supplier never negotiated on.*

## **Where this sits in sourcing**

**Get quotes from 30–50 suppliers.**

**Shortlist the best and order samples.**

**Then, while you are waiting for samples, send your top 5–10 a cost breakdown sheet.**

**That waiting period is otherwise dead time**, and it is when suppliers are most motivated to be transparent — they are still competing for the order.

See [**Negotiating Lower COGS**](https://kb.trackiq.com/hc/knowledge-base/articles/negotiating-lower-cogs).

## **What the sheet asks for**

**The supplier fills in only their own cells.** Keep the structure fixed so the responses stay comparable.

**Company information:** contact name, email, company.

**Then, line by line, every cost component:**

| Field | What it captures |
|---|---|
| **Material description** | raw material, purchased part, labour, external process, or overhead |
| **Gross weight per part** | where applicable |
| **Material price per unit** | the cost of that line |

**The sheet totals to the unit price they quoted you.**

### **A worked example — a garlic press**

| Component | Weight | Cost |
|---|---|---|
| Raw material | 1.25 kg | $1.70 |
| Steel sieve insert | 1.1 kg | $0.35 |
| Chrome plating process | | |
| Labour | | |
| Overhead / factory | | |
| **Total unit price** | | **$1.75** |

**The value is not the total. You already knew the total. It is the lines.**

## **Two things the breakdown gives you**

### **1. Line-by-line comparison across suppliers**

**Supplier A quotes $0.35 for the steel insert. Supplier B quotes $0.50.**

**That is a specific, evidenced negotiating point** — far stronger than "your price is too high", because it is a question the supplier has to answer with a reason rather than a discount.

**Do this across every line** and you find the few cents each, repeatedly, that add up.

### **2. Components that cost more than they are worth**

**Sometimes a line comes back far higher than expected relative to what it contributes.** An insert card, a piece of packaging, a secondary process.

**Then you have two options:**

**Remove it**, if the cost outweighs the benefit.

**Or source it yourself** and send it to your supplier.

**That second option is genuinely underused, and it works for a structural reason.** Your supplier sources that component too, but it is a trivial part of their overall production — so they never negotiated hard on it. **You, buying it for one product at real volume, frequently can.**

**Most worthwhile on high-revenue products**, where a few cents a unit is a serious annual number.

## **Doing the arithmetic before you negotiate**

**Work out what a cent per unit is worth to you** — annual volume × the saving — before the conversation.

**That number decides how hard to push, and on which lines.** Five cents on a product selling 200 units a day is $3,650 a year; on one selling 5 a day it is $91 and not worth the relationship cost.

**Knowing which products carry enough volume to justify a hard negotiation is the input to all of this** — see [**Where Your Margin Actually Goes**](https://kb.trackiq.com/hc/knowledge-base/articles/where-your-margin-actually-goes). It also tells you where a COGS reduction actually lands: on margin, or on the room you have to advertise.

## **Common mistakes**

**Asking for a lower price** instead of a breakdown, and having nothing to negotiate with.

**Letting each supplier use their own format**, so nothing is comparable.

**Sending it after you have chosen a supplier**, when their incentive to be transparent has gone.

**Only comparing totals**, and missing the line items where the real difference sits.

**Never considering self-sourcing** a component the supplier has no reason to negotiate on.

**Negotiating hard on a low-volume product**, where the saving does not justify the relationship cost.
