Large migrations fail in the middle
A 50-listing migration can survive hand cleanup. A 5,000-listing migration cannot. The failure point is usually the middle of the catalog, where duplicate images, partial variants, old seller boilerplate, missing barcodes, and inconsistent titles start stacking up.
The safe approach is to build a repeatable pipeline before you touch Shopify Admin. Every listing should pass through the same steps, and every exception should be visible before the CSV import.
At 5,000 listings, even a 2-minute manual fix per item is more than 160 hours of work.
Shopify needs reachable image URLs, and old marketplace images often need cleanup before they look like storefront photos.
Size, color, condition, SKU, inventory, and price need to land under the right Shopify handle.
A 5,000-listing migration workflow
Do not import everything in one blind pass. Generate the full Shopify CSV, review it in slices, import a small sample, spot-check the product pages, then move into larger batches once the shape is proven.
- 01Resolve the public eBay storefront and capture canonical listing URLs.
- 02Scrape listing facts, item specifics, variants, condition, barcode, weight, dimensions, and image URLs.
- 03Download images, remove repeated seller logos or banners, and choose the safest cleaned treatment per image.
- 04Rewrite titles, body HTML, SEO titles, and SEO descriptions using source-grounded AI prompts.
- 05Create one Shopify handle per product and one row per variant or image as Shopify expects.
- 06Run review checks for marketplace policy, copy quality, barcode validity, and image mismatch warnings.
- 07Import a small sample into Shopify, inspect the live product pages, then import the remaining CSV batches.
Cost and time expectations
A large manual migration is expensive because the boring parts repeat thousands of times. If a contractor spends one minute per listing, 5,000 listings becomes more than 80 hours before QA. If they spend three minutes per listing, it becomes a month of full-time cleanup.
Storeshift is designed for the seller who wants the catalog conversion, not a consulting project. The pricing formula starts at $19 for the first 200 listings, adds $0.10 per listing after that, and caps before it becomes agency work.
What to inspect before launch
After import, do not inspect only one featured product. Check a product with variants, a product with multiple images, a product with a long description, and a product with barcode or condition data. Those four cases catch most migration shape issues.

FAQ
Can Shopify handle a 5,000-product import?
Shopify can import large product CSV files, but sellers should test a small batch first and keep row structure, image URLs, handles, and variants clean.
Should I migrate all listings at once?
Generate the full catalog, but import in controlled batches. A sample batch catches CSV and image issues before thousands of products are affected.
How much does Storeshift cost for 5,000 listings?
Storeshift uses tiered one-time pricing: $19 for the first 200 listings, then $0.10 per listing after that, subject to the product cap in the app.
