The SKU is the stock-keeping code stored on each product variant. This guide shows how to set it from another field, append or prepend text, find-and-replace, or wipe it entirely across many variants at once.

SKU is a variant field. Each variant of a product has its own SKU, so the action runs once per matched variant. A product with five variants gets five SKU updates.

No format check. The app accepts any text — letters, numbers, dashes, spaces. If your warehouse expects a specific pattern, eyeball the Edit Preview before running.

Step 1: Pick the SKU field

In the Configure Product Edits panel, click Select Field.

The Select Field button in the Configure Product Edits panel

SKU lives under Variant Fields.

The Select Field modal with SKU marked under Variant Fields

Click it. The configuration panel switches to a How to edit SKU dropdown defaulting to Set SKU to value, plus a value input.

Step 2: Choose how to change the SKU

Seven actions are available.

Direct value

Set SKU to value — every matched variant gets this exact SKU. Pair with a dynamic value (see Step 3) so each variant still gets a unique code.
Remove SKU — clears the SKU field entirely. No input shown, no value to enter.

Adjust the existing SKU

Add text to end — append text (e.g. -REFURB).
Add text to beginning — prepend (e.g. WH- for warehouse).
Remove text from end — strip a suffix.
Remove text from beginning — strip a prefix.
Find text and replace — swap one substring for another, optionally case-insensitive.

The inputs below the dropdown change based on what you pick.

Step 3: Enter the value

Set SKU to value

Type the new SKU in the Set the sku to this value input.

Use dynamic values to keep SKUs unique. Click Add dynamic value above the input. A modal opens letting you build a token from product fields (Vendor, Handle, Title, Type, Tags…) and metafields, with optional capitalization (UPPER, lower, Title Case). Picking a field inserts a token like {{product.handle}} at the cursor — combine tokens with literal text to compose a SKU template.

Set SKU to value with "VENDOR-{{product.vendor}}-{{product.handle}}" entered. The Edit Preview on the right shows each variant's SKU resolving to a unique value built from its product's vendor and handle

In this example, every matched variant gets a SKU like VENDOR-Pure Fix Cycles Charlie...-pure-fix-cycles-charlie-.... The Edit Preview resolves the tokens per variant so you can verify before running.

Setting a literal value with no dynamic token across many variants gives every variant the same SKU. Shopify lets you save duplicate SKUs, but inventory tools, reports, and integrations get confused fast — almost never what you want.

Find text and replace

Two inputs — what to look for, and what to replace it with — plus a Case insensitive checkbox.

Find text and replace mode with "OLD-" in the search field and "SS26-" in the replace field

Use this to retire an old prefix, fix a typo across the catalog, or rebrand a SKU range. Leave the replace field blank to delete the matched text outright.

Add / Remove text from end or beginning

A single input. Whatever you type gets appended, prepended, or stripped from the matching end of every SKU.

Remove SKU

No input — the action just clears the SKU field on every matched variant.

Remove SKU action selected: dropdown shows Remove SKU and there is no value input below — Start Bulk Edit Now is enabled immediately

After the run

SKU changes are reversible from the History page using Undo.
Empty SKUs are allowed by Shopify, but most apps that key off SKU (inventory sync, reports, channel integrations) will skip variants without one.
Add/Remove and Find-and-Replace actions are not idempotent — re-running them keeps modifying the SKU. Scan the Edit Preview on the right before you run; if a row already shows the prefix or replacement, running again will double-apply it.
