Migrate your BigCommerce store to Shopify

Use the Matrixify app in your Shopify store to migrate BigCommerce Products, Collections, Discounts, Customers and Orders to Shopify in just a few simple steps.
This import will use your BigCommerce store’s API to get the most detailed data:

• convert your BigCommerce Products into Shopify Products,
• create Custom Collections that your Products are in,
• create Redirects from the old BigCommerce Product and Collection URLs to the Shopify URL,
• migrate BigCommerce Customers to Shopify, including Customer Store Credits,
• migrate Orders from BigCommerce to Shopify,
• convert BigConnerce Coupons and Promotions to Shopify Discounts.

Let’s dig into the process of migrating the BigCommerce store to Shopify.

Steps to migrate from BigCommerce to Shopify:

1. Create BigCommerce API credentials.
2. Upload the credentials text file to Matrixify, or use the BigCommerce API URL to migrate only some of the data.
3. Under Options, choose “Dry Run” – to not import just yet.
4. Download the generated Import Results file and check that data is as you need, make corrections if needed.
5. Import your edited Excel spreadsheet file.
6. Enjoy your BigCommerce data in your Shopify store.

1. Create BigCommerce API credentials

In your BigCommerce admin, go into Settings -> Store-level API Accounts and click the “Create API Account” button.

A new page will open where you can give a name to the API Account and select permissions.

Set Token Type to V2/V3 API Token.

You can set any Name to the API Account, for example, “Matrixify Migration“.

In permissions, you must set the following scopes to read-only permission, depending on what data you are migrating:

• Products:
  • Products – to access Product details,
  • Information & settings – for BigCommerce stores’ settings and store units,
• Collections:
  • Products – to access Collections and their Products data,
  • Information & settings – for BigCommerce stores’ settings and store units,
• Customers:
  • Customers – to access BigCommerce Customers’ data,
• Orders:
  • Orders – to access Orders data,
  • Order transactions to access the historic Transactions data,
• Discounts:
  • Marketing – to get actual coupon and promotion data,
  • Information & settings – for BigCommerce stores’ settings and currency data,
  • Products – to get product data when a Discount applies to specific Products,
  • Customers – for BigCommerce Customer groups data when a Discount applies to specific Customer groups.

Any other permissions can stay on their default values.

If you will use the Customers or Orders date filters from step 2, also set Information & settings to read-only. The app reads your BigCommerce store time zone with it.

Click the “Save” button once you are finished.

A TXT file should download automatically to your computer. That contains your API credentials.

The credentials txt file name is like this:
BigCommerceAPI-credentials-h87k1m5ck1voo0q85fus4wbj6ifdq1n-.txt
(and you should keep it that way).

2. Upload the credentials text file to Matrixify

Now you can head into your Shopify store and open the Matrixify app.
On the app Home page, you can see the Import section. Click on it to select the credentials text file from your computer, or drag and drop it in the import area.

You should see that the app detects the import format as “BigCommerce API“.

As the app analyzes BigCommerce data, a count will be returned for number of Products, Collections, Customers, Redirects, Orders and Discounts.

If a scope permission is missing from BigCommerce API credentials, then that specific entity sheet will show as not selected with a message about what BigCommerce scopes are missing from the API credentials.

Use the BigCommerce API URL instead of the file

Instead of uploading the credentials file, you can build a URL from the same credentials and Import from it. Use it when you need to migrate only some of the data – for example only Customers and Orders, or only the Customers and Orders added or changed after your first migration. Filters can be set only in the URL. The credentials file always migrates everything.

The URL is built like this:

https://<CLIENT ID>:<ACCESS TOKEN>@api.bigcommerce.com/stores/<STORE HASH>/v3/

All values are in the credentials text file from step 1. Take the API PATH value, like https://api.bigcommerce.com/stores/abc123xyz/v3/, and put <CLIENT ID>:<ACCESS TOKEN>@ right after https://. For example:

https://h87k1m5ck1voo0q85fus4wbj6ifdq1n:[email protected]/stores/abc123xyz/v3/

In the Matrixify app Home, paste the URL in the Import section and press Upload from URL. The app detects the format as BigCommerce API, the same as with the file. The counts show only the data that matches your filters.

Migrate only selected BigCommerce data

Add ?only= at the end of the URL with a comma-separated list of what to migrate. For example, ?only=customers,orders migrates only Customers and Orders.

• products
• categories – migrated as Custom Collections
• customers
• orders
• discounts – BigCommerce Coupons and Promotions

Redirects are created when products or categories are migrated. Any other value fails the Import with a message that lists the accepted values.

Filter BigCommerce Customers and Orders by date

Date filters migrate only the Customers or Orders created or last modified in a date range. Add each filter after &, or after ? when it is the first parameter in the URL.

Customers:

• customers_created_since – created on or after the date
• customers_created_before – created before the date
• customers_updated_since – last modified on or after the date
• customers_updated_before – last modified before the date

Orders:

• orders_created_since – created on or after the date
• orders_created_before – created before the date
• orders_updated_since – last modified on or after the date
• orders_updated_before – last modified before the date

A since date includes that exact moment, a before date does not. So customers_created_since=2026-11-10T14:04:00 includes a Customer created at 14:04:00, and customers_created_before=2026-11-10T14:04:00 leaves that Customer out. When you add several filters, an item has to match all of them.

For example, this migrates only Customers created in the first half of 2026:

?only=customers&customers_created_since=2026-01-01T00:00:00&customers_created_before=2026-07-01T00:00:00

After a full migration, this migrates only the Customers and Orders added or changed in BigCommerce since October 1, 2026:

?only=customers,orders&customers_updated_since=2026-10-01T00:00:00&orders_updated_since=2026-10-01T00:00:00

Date format:

• Write dates in ISO 8601 format, like 2026-01-01T00:00:00. A date alone, like 2026-01-01, means the start of that day.
• Dates are read in your BigCommerce store time zone, not in your Shopify store time zone.
• Do not add a time zone to the date, like Z or +02:00 – the app does not use it. Write the time as it is in your BigCommerce store time zone.
• For a repeating Import you can use dynamic placeholders. They are filled in with the current date and time in your BigCommerce store time zone. For example, orders_created_since=%Y-%m-01T00:00:00 migrates the Orders created since the start of the current month.

A value that is not a date, like customers_created_since=last-week, fails the Import before anything is migrated. The message names the filter and shows the format to use.

Customers date filters are used only when Customers are migrated, and Orders date filters only when Orders are migrated. Otherwise they are ignored.

The date filters need the Information & settings scope from step 1. Without it, the Import fails before anything is migrated, with a message to create an API token with that scope.

3. Select the “Dry Run” option to generate an Excel file

Once you have confirmed that details about the job look correct, you can scroll down to the “Options” section of the import job.

In the Options, you would need to select the “Dry Run – convert the file and test as far as possible without actually importing anything” option.

Leave all other options as they are by default.

With Dry Run, the app will take data from the BigCommerce API and only generate an Excel file according to the Matrixify template without actually importing any data.

Now you can click the “Import” button and the app will generate the dry-run file.

4. Download generated Import Results file and check data

Once the dry-run has completed, which should be relatively quick, you can press the “Download Import Results file” button to download the generated file.

You will get the zip file with your data prepared for the migration.
In the zip file, you should see the folder “Images” and Excel file “Import_Result.xlsx“.

The Images folder is generated with image files if products or collections in your store contain images in their description HTML code.
The app will change for image links in HTML code to point to Shopify Files so that they no longer point to the BigCommerce site.
You would need to unzip the zip file and upload all image files in your Shopify Admin -> Settings -> Files.

If there are no Image files, do not worry – it means that your description HTML does not have any images in the HTML code. Actual Product images still will be migrated.

Once images are imported in Shopify Files, you can check the “Import_Result.xlsx” file.
If you need to check your data before importing or clean it up – you can open that file and work your changes in it.
Data in this file is organized according to the Matrixify template.

Note that the Excel file contains multiple sheets/tabs all of which will be imported:

• Products
• Custom Collections
• Customers
• Redirects
• Orders
• Discounts

Each column from Matrixify template sheets is explained in those documentation pages:

• Products template documentation
• Custom Collections template documentation
• Customer template documentation
• Order template documentation
• Discounts template documentation
• Redirects template documentation

In that Excel file – feel free to clean up and update any data that you need to change, before importing to Shopify. And, of course, if you don’t need to change anything, then you don’t have to – you can just import that Excel file as it is.

5. Import your Excel file

Once you have checked that all data matches your needs you can finally import the file.

Head back to the Matrixify app and on the Home page, Import section upload your corrected Excel file.
Now you should see that the import format shows as “Matrixify”.

Make sure that item counts are correct and that there are no unexpected warnings showing.

This time, you do not need to select or change any options.

If there are any inconsistencies, please contact Matrixify support, before importing your data.
Check that everything is correct and then press the “Import” button to start actually importing data into Shopify.

6. Enjoy your BigCommerce data in Shopify

After the Import has finished, you can check and enjoy your Products, Collections, Customers, Orders and Discounts migrated from BigCommerce to Shopify!

Good to know!

• Create your Shopify store.
• Install the Matrixify app.
• If you have any questions or issues during the migration, do not hesitate to contact Matrixify support.
• Using the method in this tutorial, you can also migrate BigCommerce Store Credits to Shopify. This is included as part of the Customer’s sheet.
• When Customers and Orders are migrated in the same Import with a Customers date filter, Orders whose Customer is outside the date range are still migrated. Such an Order takes Customer: Email and Customer: Phone from its billing address.
• Do not have access to the BigCommerce API for Products migration? Check out our tutorial on how to migrate Products to Shopify using the BigCommerce CSV file.
• All the migrated data is really yours – it stays on your Shopify store even after you have uninstalled the Matrixify app (but you can also continue using Matrixify for other data exports, imports, and updates).
