Can I migrate a large customer base to Shopify?

Shopify Discussion

  • I am migrating to shopify and would like to find out if there are any limitations on how many customers can be migrated.

We have a large customer base, over 200,000. If this is too large, what is the maximum number of customers we can add.

Thank you!

I don’t believe there is any limit. There are some limits on the number of product variants you can have though.

Hi @Raffid

Great question! There is no limit to the number of customer accounts your store can have. The only limit that you might run into is CSV import files are limited in size to about 15-20MB, depending on the type of import. So if you are importing by CSV you will need to break up the imports, which I would recommend doing anyways.

You can learn more about customer CSVs and get a template of our CSV file in our Help Center here: Shopify Help Center | Importing and exporting customers.

Shopify does not impose a strict limit on the number of customers you can migrate, so importing a large customer base—like your 200,000+ records—is entirely possible. However, the process may take longer depending on the size and complexity of your data. Cart2Cart is a great solution for handling bulk migrations like this, as it supports high-volume transfers of customers, products, and orders efficiently. If needed, Cart2Cart’s support team can assist with large-scale or customized migrations to ensure a smooth transition.
