LitExtension: Migrate Your Store to Squarespace

LitExtension is an automated data migration service that moves an existing online store onto Squarespace (or off it) without manual CSV wrangling. It transfers products, customers, orders, and blog content from 140+ platforms, while your current store stays live throughout. This page is a plain-English rundown of what it is, what it does, what it costs, and the important things it can and cannot move.

Best for: Anyone moving an existing store (from Shopify, Wix, WooCommerce, Square, and others) onto Squarespace who wants it done accurately without technical work.

What it is

LitExtension is the leading eCommerce migration service, with over 280,000 migrations and more than 200,000 customers across ten-plus years. It moves your store data automatically between 140+ platforms (Shopify, WooCommerce, Wix, Webflow, Square, BigCommerce, Magento, and many more) and Squarespace, in both directions. The migration runs in the cloud, so it keeps going even if you close your browser, and crucially your existing store stays fully live and able to take orders throughout, with no downtime and no data loss. You can run a free Demo Migration first to preview exactly how your data will look on Squarespace before committing.

What it does

LitExtension handles the data side of a platform move in three guided steps. Key points include:

• Migrates the core data: products (with variants, images, and SKUs), categories, customers, orders, and blog posts into Squarespace.
• 140+ supported platforms, including Shopify, WooCommerce, Wix, Webflow, Square, BigCommerce, Magento, and PrestaShop, in and out of Squarespace.
• No downtime: your current store keeps running and taking orders while the migration happens in the cloud.
• A free Demo Migration to preview results, plus a Pricing Estimator to see the cost before you start.
• 301 redirect help to preserve SEO value where source and Squarespace URL structures differ (more on this below).
• Two ways to run it: the automated self-service tool, or the All-in-One package where a Personal Assistant manages the whole migration for you.
• 24/7 support by live chat, email, and ticket, with around 99 percent reported satisfaction.

What it cannot migrate (read this first)

This is the honest part that matters most, because a migration moves your data, not your whole website. A few things cannot transfer, by design:

• Design, theme, and custom CSS cannot be migrated. Squarespace uses its own templates, so you recreate the look separately (which, with Squarespace’s templates, is often a welcome refresh anyway).
• Customer passwords cannot transfer, for security reasons. Customer records move across, but each customer resets their password on first login.
• Credit card details are never transferred between platforms.
• SEO URLs: because Squarespace uses its own URL structure, direct SEO-URL migration from some platforms (such as Webflow) is not supported. The key move here is setting up 301 redirects, which LitExtension helps with, so your existing search rankings are preserved rather than lost. Treat this as the single most important step for protecting your traffic.

One more practical note if you are migrating out of Squarespace: Squarespace caps CSV exports at 2,000 products, with each variant counted separately, so larger catalogues need planning, which the service handles for you.

Pricing

LitExtension pricing starts from around $59 and scales with the number of entities you migrate (products, customers, orders), so a small store costs little and a large one costs more. The Pricing Estimator on their site gives an exact figure before you commit. As a rough guide:

• Automated migration: from around $59, priced by your data volume. You run the guided self-service tool.
• All-in-One package: a premium, fully managed option where a Personal Assistant handles the entire migration to a high standard.
• Free Demo Migration: preview a limited migration at no cost before paying for the full transfer.

For context on the destination: Squarespace plans run roughly from $16 per month (Basic) up to around $99 per month (Advanced) on annual billing, so factor your ongoing Squarespace subscription in alongside the one-off migration cost.

Who it is for

LitExtension is for anyone with an existing store who wants to move to Squarespace accurately and without manual effort: someone leaving Shopify, Wix, Square, WooCommerce, or another platform who would otherwise be exporting and reformatting CSV files by hand and risking errors. It removes the technical risk from the data move and keeps the old store live so you lose no sales during the switch. It is less relevant if you are starting a brand-new Squarespace store with no existing data to bring across, or if your catalogue is tiny enough that a manual CSV import feels trivial, though even then the free Demo Migration is worth a look to compare.

Our verdict

If you are moving an existing store to Squarespace, LitExtension is the established, low-risk way to do it: it transfers your products, customers, and orders accurately, keeps your current store live throughout, and lets you preview the result for free first. The reason it is worth using rather than wrestling with CSV exports is precisely the detail, variants, relationships, and the SEO side. Go in clear that design and passwords do not transfer and that protecting your rankings depends on setting up 301 redirects, which the service helps with. For a high-stakes platform move where getting the data right matters, it is a sensible, well-proven choice, and the free Demo Migration means you can see exactly what you will get before paying.

Frequently asked questions

Can LitExtension migrate my store to Squarespace?
Yes. It moves products, customers, orders, categories, and blog content into Squarespace from 140+ platforms, including Shopify, Wix, WooCommerce, Square, Webflow, and BigCommerce. You can preview it first with a free Demo Migration.

Will my store go offline during the migration?
No. The migration runs in the cloud and your current store stays fully live and able to take orders throughout, with no downtime and no data loss.

Does my website design transfer to Squarespace?
No. Design, theme, and custom CSS cannot be migrated, because Squarespace uses its own templates. Your data moves across, and you recreate the look using Squarespace’s design tools, which is often a useful refresh.

Will I lose my SEO rankings?
Not if you handle URLs correctly. Squarespace uses its own URL structure, so direct SEO-URL migration is not always supported, but LitExtension helps you set up 301 redirects so your existing search value is preserved. This is the most important step to get right.

How much does LitExtension cost?
Pricing starts from around $59 and depends on how many products, customers, and orders you migrate. A free Demo Migration and a Pricing Estimator let you see the result and the exact cost before committing, and an All-in-One managed package is available if you want experts to handle everything.
