Post-merge checklist: what to do after your first merge

A merge is saved when Shopify shows the new product in your admin. Everything downstream - storefront rendering, fulfillment, reporting, marketing integrations - still needs a quick pass. Run through this checklist the first time you merge, and again any time you do a large merge with many variants or third-party integrations.

1. Verify the merged product in Shopify admin

Open the merged product in the Shopify admin and confirm:

• Title and description read cleanly and match your brand voice. The AI draft is a starting point, not a final copy.
• Images are present, in the right order, and show the variant they correspond to.
• Variants list every combination you expected. Each variant has a price, SKU, and (where relevant) barcode.
• Inventory quantities match what the source products had before the merge.
• Options (Color, Size, etc.) are named the way your customers see them on the storefront.
• Product category and type are set correctly - these drive tax rates and discovery.

If anything is wrong, fix it in the Shopify admin now. The merged product is a native Shopify product, so normal admin edits apply.

2. Check the source products

Merges archives every source product when the merge is saved. Confirm:

• Source products have status Archived (not Active, not Draft).
• You are not seeing duplicates in collections, search, or the storefront.
• Nothing else in your store links to the old product handles - internal navigation, landing pages, email templates, ad creative.

301 redirects are generated automatically on PRO and UNLIMITED plans so old URLs continue to resolve. See URL redirects with Merges for details.

3. Publish to the right sales channels

Open the Sales channels panel on the merged product. Confirm the product is published to:

• Online Store (if you sell direct to customers).
• POS (if you sell in-store).
• Buy Button, Shop, Google, Facebook, Instagram, TikTok, or any other channel you use.
• Any custom apps or headless storefronts that read from Shopify's publication API.

Channel visibility is merged from the source products, but conflicts resolve in favor of the most-visible setting. Double-check anything customer-facing.

4. Open the merged product on your storefront

Visit the live product page on your online store and walk through the flow a real customer would:

• Variant picker shows the correct options and values.
• Image switching updates the main image when a customer picks a different variant.
• Price updates correctly when variants have different prices.
• Add to cart works from every variant combination.
• Out-of-stock states render correctly for any variant with zero inventory.

For merged products with more than 100 variants, test on a few different browsers and on mobile. Some older themes struggle to render large variant pickers. See Advanced usage and limitations for theme notes.

5. Confirm third-party fulfillment is reconnected

If any source product was managed by a dropshipper or fulfillment app, the new variant IDs need to be reassigned before stock and orders sync correctly:

• Printful - enable Sync original products and Order routing in Merges under Settings. See Using Merges with third-party fulfillment.
• GigaB2B - contact their support to remap SKUs to the new variant IDs. GigaB2B's mappings are variant-ID-based and do not update automatically after a merge.
• Spark Shipping - no manual step required. Spark identifies products by SKU, which Merges preserves, so the next sync picks up merged variants automatically.
• Other fulfillment apps - see Managing inventory after product merging.

Do not reimport the original products from your supplier. That will recreate the old listings and split your inventory.

6. Verify integrations and apps

Walk through the apps that touched the source products:

• Review apps - reviews carried across if stored in Shopify metafields. Judge.me requires Product Groups. See Keeping Judge.me reviews on merged products.
• Metafields - definition-based metafields transfer automatically. Legacy unstructured metafields do not. Check Settings -> Metafields and metaobjects in Shopify if something is missing.
• Subscription apps, loyalty programs, wishlists - these often store references to product IDs. Check that subscribers, points, and wishlists still resolve to a valid product.
• Analytics and pixel integrations - Google Analytics, Meta Pixel, TikTok Pixel will naturally start tracking the new product. Historical data for the source products stays on the source products (which are now archived).

7. Update marketing and internal systems

Anywhere you reference the product by URL, image, or handle:

• Email templates and upcoming campaigns.
• Paid ad creative (Meta, Google, TikTok) - update the destination URL even if the redirect handles it, for cleaner reporting.
• Internal docs, spreadsheets, and inventory trackers.
• PIM, ERP, or OMS systems that sync from Shopify.

8. Give it 24 hours, then review

Some things settle over time:

• Stock levels may take a few minutes to several hours to fully sync, depending on your fulfillment provider.
• Search indexing on your storefront may take a few hours to update.
• Third-party analytics typically show the merged product in reports within 24-48 hours.

After 24 hours, spot-check the merged product one more time. If anything still looks off, open the troubleshooting guide or email support@merges.io with the merged product URL.
