Amazon's **Bulk Services** programme exists to accelerate multipack sales, and to get sellers to use it Amazon offers **up to a 25% reduction on the referral fee**.

**That is a permanent margin gain on products you already sell**, requiring nothing but a catalogue change.

**It launched for seller-fulfilled orders — but it works on FBA orders too.**

*Prefer to watch? One hundred and forty-seven seconds on what the discount is worth in margin points, the package level setup, and verifying it on a real order.*

## **What it is worth**

**On $1,000/month of referral fees for one product:**

| Units in pack | Monthly saving | Extra margin at a 15% referral fee |
|---|---|---|
| **2–9** | **$150** | **+2.25%** |
| **10–23** | **$200** | **+3.0%** |
| **24+** | **$250** | **+3.75%** |

**Three and a bit points of margin, straight to the bottom line, forever.** Very little else on Amazon pays that much for an afternoon of catalogue work.

**Run the arithmetic on your own products first** — see [**Where Your Margin Actually Goes**](https://kb.trackiq.com/hc/knowledge-base/articles/where-your-margin-actually-goes).

## **Does your product qualify?**

**Price must be at least $20 / £20 / €20.**

**And at least one of:**

**10 or more units in the pack**, or

**2+ units and total volume at least 1,400 cu in / cm³**, or

**2+ units and total weight at least 35 lb / 35 kg.**

### **Where it works**

**US** — live and running.

**UK and Germany** — enrolment works, though Amazon's help documentation is thin. Assume the US thresholds apply until told otherwise.

**Canada** — does not work.

**Clothing and supplements are generally excluded** in every marketplace.

## **The process**

**Four steps.**

**1. Make sure a single-unit listing exists.**

**2. Create the CASE relationship on the multipack.**

**3. Upload it.**

**4. Verify on a live order.**

## **Step 1: the single-unit variant**

**The programme needs a UNIT listing for the multipack to point at.** If you do not have one, create it.

**Inventory → Manage All Inventory → Copy Listing** from the nearest existing product.

**Then correct everything** so it is a genuine single-unit version — you will probably need a fresh UPC.

**List it properly**, with real images and dimensions. Amazon does not currently require it to be buyable, but a half-built listing is a liability if that changes.

## **Step 2: set the package levels**

**Reports → Inventory Reports → Category Listings Report.**

**If that report is not offered, open a case asking Amazon to enable it.**

**Delete every row except the products you are handling** — do one product type at a time.

**On the single-unit row:**

| Field | Value |
|---|---|
| `package_level` | **UNIT** |

**On the multipack row:**

| Field | Value |
|---|---|
| `package_level` | **CASE** |
| `Package Contains Quantity` | units per case |
| `Package Contains Identifier` | the single-unit **SKU** |
| `Relationship Type` | `package_contains` |

**If Relationship Type is not present in your sheet, skip it.**

## **Step 3: upload**

**Catalog → Add Products Via Upload**, and upload the edited file as a **Partial Update**.

**Partial Update matters.** A full upload will overwrite fields you did not intend to touch.

## **Step 4: verify on a real order**

**Wait 24 hours**, then find a recent order showing **Payment Complete** and open its transaction details. **The referral fee line shows whether the discount applied.**

**Do not assume the upload worked.** Silent failures here are common, and you will not notice from the catalogue side.

**A referral fee that quietly stops being discounted looks exactly like a normal fee until you compare it against what it was** — see [**Understanding Business Reports**](https://kb.trackiq.com/hc/knowledge-base/articles/understanding-business-reports). Catching that from monthly settlement statements takes a quarter.

## **Keeping it working**

**Set every SKU up the same way.** Inconsistency across SKUs on the same ASIN breaks it.

**Do not reuse a SKU** that is already acting as a unit SKU elsewhere.

**Product types must match** between the unit and the case.

**A business price must be set** — see [**Business Pricing and Quantity Discounts**](https://kb.trackiq.com/hc/knowledge-base/articles/business-pricing-and-quantity-discounts).

**Set a List Price in the catalogue** — see [**Adding a List Price Strike-Through**](https://kb.trackiq.com/hc/knowledge-base/articles/adding-a-list-price-strike-through).

**Review it weekly**, using the selling economics report, the fee preview report and the category listings report. Discounts drop off silently.

**Refresh with a full update periodically** if it lapses.

## **One serious warning**

**Back up your listing data before you touch any of this.**

**Deleting either listing — the unit or the case pack — deletes the data for both.** They are linked, and the deletion is not confined to the one you deleted.

## **Common mistakes**

**Assuming it is seller-fulfilled only.** It works on FBA.

**Uploading as a full update** instead of a partial one.

**Setting it on some SKUs but not all** on the same ASIN.

**Skipping verification**, and believing a discount that never applied.

**Never re-checking**, and losing the discount without noticing.

**Deleting a linked listing**, and losing both.
