To add customers on Shopify, go to your Shopify admin, click Customers in the left menu, then click Add customer. Fill in the customer’s name, email, and any other details, then hit Save. You can also bulk import customers using a CSV file. This guide walks through both methods step by step, along with required fields, tagging, and privacy rules you need to follow.

Whether you are migrating from another platform, adding contacts from a trade show, or building your customer list from scratch, Shopify gives you two main ways to add customers: manually one at a time, or in bulk through a CSV file upload.

Key Takeaways
1
Manual customer entry works best for individual profiles; CSV import handles bulk additions from migrations or events.
2
Always have documented consent before ticking “Customer accepts marketing” - required under GDPR, CCPA, and CAN-SPAM.
3
Use tags from day one: retroactively tagging hundreds of customers is far more work than doing it during import.
4
Customers added by the merchant do not have login access until you send them an account invite from their profile page.

How to Add a Customer Manually on Shopify

The manual method works best when you need to add one or a handful of customers. Here is exactly how to do it.

Step 1: Check You Have Permission

Before entering anyone’s details into your store, confirm you have their consent. Privacy laws like GDPR (EU), CCPA (California), and PIPEDA (Canada) require that customers agree to have their personal data stored. If you are transferring customers from another platform, keep a copy of the old records as proof of original consent.

For new contacts collected at events or in-store, use a signup form with a clear checkbox stating that the customer agrees to have their information stored. Do not rely on verbal agreement - it will not hold up if challenged.

Step 2: Open the Customers Section

Log into your Shopify admin at yourstorename.myshopify.com/admin. In the left sidebar, click Customers. This opens your full customer list, where you can search existing profiles or add new ones.

Step 3: Click “Add Customer”

In the top-right corner of the Customers page, click the Add customer button. This opens a blank customer profile form.

Step 4: Fill In Customer Details

The form has several fields. Not all are required, but knowing which ones matter will save you time and keep your data clean.

Required fields:

  • First name and Last name - at minimum, you need one of these
  • Email address - needed if you plan to send order confirmations, receipts, or marketing emails

Optional but recommended fields:

  • Phone number - useful for SMS marketing or order delivery updates
  • Address (street, city, state/province, zip, country) - pre-fills at checkout, reducing cart abandonment
  • Company - helpful for B2B stores or wholesale accounts
  • Notes - internal-only field visible to your staff, not the customer. Use it for context like “Met at NYC trade show March 2026”
  • Tags - covered in detail below

Two checkboxes at the bottom of the form are worth paying attention to:

  • Customer accepts marketing - only tick this if you have explicit consent. Sending marketing emails without consent violates most anti-spam laws.
  • Tax exempt - tick this for wholesale buyers, resellers, or non-profit organizations that qualify for tax exemption in your jurisdiction.

Step 5: Save the Customer

Click Save in the top-right corner. The customer profile is now live in your store. They will not receive any notification unless you manually send them an account invite email from their profile page.

How to Bulk Import Customers Using a CSV File

If you have dozens or hundreds of customers to add - for example, when migrating from WooCommerce, BigCommerce, or a spreadsheet from your old POS system - the CSV import method is far faster than adding each one manually.

Prepare Your CSV File

Shopify accepts a specific CSV format. You can download a sample template from the Shopify admin import screen. The key columns are:

  • First Name, Last Name
  • Email
  • Phone
  • Accepts Marketing (yes/no)
  • Tags (comma-separated within the cell)
  • Address1, Address2, City, Province, Province Code, Country, Country Code, Zip
  • Note
  • Tax Exempt (yes/no)

Save your file as UTF-8 encoded CSV. This prevents character issues with accented names or international addresses.

Upload the CSV

In your Shopify admin, go to Customers, then click Import in the top-right area. Select your CSV file and click Import customers. Shopify will process the file and show a summary of how many records were added, updated, or skipped due to errors.

If a customer email already exists in your store, Shopify will update that record with any new information from the CSV rather than creating a duplicate. This makes re-imports safe if you need to update addresses or tags in bulk.

Using Customer Tags for Segmentation

Tags are one of the most underused features in Shopify’s customer management. A tag is a label you attach to a customer profile - you can add as many as you want, and they are searchable and filterable.

Practical tag examples:

  • vip - customers who have spent over a certain amount
  • wholesale - B2B buyers with different pricing
  • tradeshow-nyc-2026 - where you collected the contact
  • newsletter-only - signed up for emails but has not purchased yet
  • return-risk - customers with a high return rate

To add tags manually, open a customer profile and type the tag in the Tags field. Press Enter or add a comma to confirm each tag. In a CSV import, put all tags for one customer in a single cell, separated by commas.

Tags power Shopify’s customer segments feature, which lets you create automatic groups based on tag values, spending history, location, and more. Setting up tags from day one saves significant time later when you start running targeted email or discount campaigns.

Common Mistakes When Adding Customers

These are the errors that cause the most problems, based on what store owners frequently run into - split between mistakes to avoid upfront and error messages you may hit during the process.

Mistakes to Avoid Before You Start

  • Duplicate email addresses - if two rows in your CSV have the same email, Shopify merges them. This is usually fine, but can overwrite address data you wanted to keep. Review your CSV for duplicates before importing.
  • Ticking “accepts marketing” without consent - this can result in spam complaints, email provider bans, and legal penalties under GDPR or CAN-SPAM. Only mark this if the customer has actively opted in.
  • Skipping tags - adding 500 customers with no tags makes them impossible to segment later. Always tag during import, not after.
  • Wrong CSV encoding - saving as ANSI instead of UTF-8 corrupts special characters. Always use UTF-8.
  • Forgetting to send account invites - adding a customer to Shopify does not give them a login. If you want them to create an account and view order history, you need to send an account invite from their profile page after saving.

Error Messages and What They Mean

  • “Email already taken” error - the email address is already on another customer profile (maybe a duplicate from a previous CSV import, maybe a wholesale and retail split). Search by email first; merge if appropriate, or use a tagged variant.
  • CSV import fails silently - most CSV failures come from malformed headers, smart quotes pasted from Word, or non-UTF-8 encoding. Open the file in a plain text editor; re-save as UTF-8 CSV with straight quotes.
  • Customer can’t reset their password - the “Send account invite” email goes to spam more often than other Shopify emails. If a customer says they didn’t receive it, check the email under Customers > Email logs, ask them to whitelist your domain, and resend.
  • Tags don’t filter properly - tags in Shopify are case-sensitive in some flows. Standardize tag casing (always lowercase, no spaces) at the point of creation, not after.
  • Customer added but doesn’t appear in marketing list - the customer probably wasn’t subscribed during import. Check Settings > Notifications and confirm the “Accepts marketing” field was set during CSV upload.

Customer Data You Can Sync to Shopify (Without Manual Entry)

For larger customer lists or recurring sync needs, Shopify supports automated customer data import beyond manual entry and CSV upload:

  • Shopify Admin API (Customer endpoint). Developers can create, update, and bulk-sync customers programmatically via REST or GraphQL. Useful when integrating with an external CRM, accounting system, or membership platform that should keep Shopify customers in sync. Most stores hire a developer for the initial integration, then run on autopilot.
  • Migration tools when switching platforms. Cart2Cart, LitExtension, and Matrixify (formerly Excelify) handle bulk customer migrations from WooCommerce, BigCommerce, Magento, Squarespace, and other platforms. They preserve customer history, segmentation tags, and (where available) order history. Pricing typically $50-500 depending on customer count.
  • Shopify Flow for auto-tagging. Plus stores get Flow free; standard plans can use it via the Flow app. Flow can auto-tag customers based on behavior: “VIP” after 3+ orders, “high-value” after $500 in lifetime spend, “at-risk” after 90 days without a purchase. The tags update automatically, so segmentation stays current without manual work.
  • Email platform sync. Klaviyo, Omnisend, and Shopify Email integrate two-way with Shopify customers. A signup on your email form creates a Shopify customer; a Shopify purchase updates the email subscriber profile with order data. Most stores want this two-way sync turned on.

For most Shopify stores under 5,000 customers, manual entry and CSV import is fine. The API and migration tools matter when you’re moving in from another platform or syncing with external systems where double-entry would create errors.

Privacy and Consent: What You Actually Need to Do

Privacy compliance is not optional, and the rules vary by region. Here is a practical breakdown:

  • GDPR (EU/UK) - you need explicit, documented consent to store personal data. You must also honor deletion requests (“right to be forgotten”). Keep records of when and how consent was given.
  • CCPA (California) - customers have the right to know what data you store and to request deletion. You do not need consent to collect, but you must disclose and delete on request.
  • PIPEDA (Canada) - requires meaningful consent and limits data collection to what is necessary for the stated purpose.
  • CAN-SPAM / CASL - these govern email marketing specifically. CAN-SPAM (US) requires an unsubscribe link and honest subject lines. CASL (Canada) requires express opt-in before sending commercial emails.

For most Shopify store owners, the practical steps are:

  • Add a consent checkbox to any form where you collect customer details
  • Keep a record of when each customer gave consent (a screenshot, a database timestamp, or the original signup form)
  • Only tick “accepts marketing” in Shopify for customers who have explicitly opted in
  • Have a process for handling data deletion requests - Shopify lets you delete customer data from the admin under the customer’s profile

What Happens After You Add a Customer

Once a customer is saved in Shopify, a handful of things happen behind the scenes that affect what you can do with them next:

  • They appear in your customer segments. Any saved segments (e.g. “Customers from Canada,” “Customers tagged wholesale”) automatically include the new record if they match the filters. This means newly-added customers can immediately receive segment-targeted email or SMS campaigns without manual list rebuilding.
  • They get a customer ID and unique URL. Each profile gets a Shopify-internal ID and an admin URL of the form /admin/customers/{id}. Useful for direct links from internal tools, support tickets, or staff training documentation.
  • They don’t get a welcome email automatically. Adding a customer through the admin or CSV does NOT send a welcome message. If you want one, use a flow in Shopify Email or Klaviyo triggered by the “Customer created” event, or send a manual invitation from the customer’s profile.
  • Their account is not active until they accept an invite. Customers added by the merchant don’t have a password until they receive an “Account invite” and create one. Send the invite from the customer profile (Send account invite button) so they can log in to track orders and re-use saved addresses.
  • Their data counts toward your Shopify plan limits. The Basic plan caps customer profiles at 1 million; Advanced and above remove the cap. For most stores this is irrelevant, but high-volume direct-import migrations can hit the ceiling.
