Customers you add at the register in Square often never reach your email marketing list, CRM, accounting software, or the phone contacts your team uses every day. Keeping these lists aligned by hand is slow and causes errors, duplicates, and outdated details. The Square Customers connector closes this gap by syncing your customer directory automatically. Every system then has the same accurate, current customer information.

How does it work?

The Square Customers connector links your Square customer directory to the rest of your business tools. With SyncPenguin, you can keep Square customers automatically in sync with your phone and email contacts, CRM, accounting software, or email marketing platform, in one or both directions. Names, emails, phone numbers, addresses, birthdays, notes, and more stay up to date everywhere, without manual exports or copy-pasting. You decide what gets synced and how, using simple no-code rules and filters.

Key features

Two-Way Sync

Keep Square customers and your other apps updated in both directions. New customers, edits, and deletions flow automatically.

Near Real-Time

Square notifies SyncPenguin when customers change, so updates and deletions are picked up quickly instead of waiting for the next scheduled sync.

Group-Based Filters

Use Square customer groups in filters and rules, for example to sync only VIPs, loyalty members, or wholesale customers.

No Duplicates

Smart matching by email links existing records during the initial merge, so your customer lists stay clean.

Smart Addresses

Country names from other apps are converted to the format Square expects, so customer addresses sync correctly.

Affordable & Scalable

With SyncPenguin you only pay for changes to your data, regardless of how many contacts you initially have, or will have in the future.

Supported fields

First name Last name Company Notes Reference ID Birthdate Email Phone Address Customer groups (read-only)

Things to note

• Square stores one email, one phone number, and one address per customer. When syncing from apps that hold several, SyncPenguin uses the work one (or the first available). You can pick a different one with custom rules.
• Square customer groups can be synced to other apps and used in filters and rules, but group membership is not changed in Square.
• Square custom attributes are not currently supported. Standard customer fields are fully supported.
• Customer profiles with no name, company, email, or phone are skipped, as they don't contain useful contact information.
• Countries are converted to standard two-letter country codes for Square. Misspelled or unusual country names may be left blank.

Frequently Asked Questions

Can I sync Square customers with Google Contacts or Outlook?

Yes. SyncPenguin can sync your Square customer directory with Google Contacts, Outlook, Microsoft 365, Apple iCloud Contacts, and many other contact apps, CRMs, and accounting tools.

Is the sync one-way or two-way?

Both are supported. You can sync customers from Square to another app, from another app to Square, or keep both sides updated in both directions.

Will syncing create duplicate customers?

No. When you start a sync, you can merge existing records first. SyncPenguin matches customers, for example by email, so existing records are linked instead of duplicated.

Can I sync only some of my Square customers?

Yes. With no-code filters, you can sync only the customers you need, for example members of a specific Square customer group or customers with an email address.

How quickly are changes synced?

Square notifies SyncPenguin about customer changes, so updates are typically synced within minutes. Regular scheduled syncs also run to make sure nothing is missed.

Do I need any technical skills to set it up?

No. You connect your Square account securely with a few clicks and configure everything in SyncPenguin's no-code dashboard. Common fields are mapped automatically.

Does it work with a Square Sandbox account?

Yes. Sandbox accounts are supported and clearly labeled, which makes it easy to test your setup before going live.
