The good news? Square has several support channels. The challenge is knowing which option gets you the fastest answer — and how to avoid wasting time when you’re in the middle of a rush.

This guide walks you through every Square support option, how to reach a real human, and the most common Square problems we see (with quick fixes). You’ll also find a link to our free POS troubleshooting assistant that walks you through Square issues step-by-step.

Square Customer Support Options (Complete Guide)

1. Square Support Phone Number (Fastest Live Help)

If you need real-time help with payments, deposits, or hardware during business hours, calling Square is usually the quickest option.

Square Customer Service Phone: (855) 700-6000
Square Website: squareup.com

Phone Support Hours: Monday–Friday, 6 AM–6 PM PST

Phone support is helpful for:

• Card reader not connecting
• Payments failing or stuck
• Account verification or deposits on hold
• Hardware malfunction (Register, Terminal, Stand)

Before calling, have this info ready:

• Square account email
• Device type (iPad, Square Terminal, Register)
• Any error messages you’re seeing
• Your unique customer code (Square requires this)

2. Check Square System Status (Before You Troubleshoot)

If Square payments or hardware suddenly stop working, there may be a platform-wide issue.

Square System Status Page: https://www.issquareup.com

From this page you can:

• Check if payment processing is degraded
• See outages affecting Register, POS app, or Dashboard
• Review recent incidents
• Confirm delays with deposits or transfers

If you see “Major Outage” or “Degraded Performance,” your issue will likely resolve automatically once systems recover.

3. Square Support Center (Best for Tutorials & How-To Fixes)

The Support Center is where Square hosts all their guides, troubleshooting steps, and help articles. You’ll also find community discussions from other Square users.

Square Support Center: https://squareup.com/help

Best for:

• Setup questions
• Menu/item configuration
• Square Online help
• Managing invoices, teams, or permissions
• Troubleshooting readers, printers, or hardware

Be sure to sign in — it unlocks account-specific support options.

4. Submit a Support Request Through Your Dashboard

If you need deeper technical help, Square lets you submit detailed support cases through your Dashboard.

These are ideal for:

• Deposit issues or account holds
• Complex Square Online store issues
• Recurring hardware failures
• API or advanced configuration problems

Include:

• Screenshots of error messages
• Your device type
• Steps you’ve already tried
• Approximate time the issue began

Detailed cases tend to get routed to the right team faster.

5. In-App Support (Fastest Self-Service Option)

If you’re using the Square POS app on iPad, Register, or Terminal, you can access support directly inside the app.

How to access support in the Square POS app:

1. Open Square POS
2. Tap More
3. Select Support → Help
4. Search or browse troubleshooting topics

This is often the fastest way to get device-specific fixes.

• Try another card (many declines are bank-related)

3. Square Deposits Delayed or Missing

• Check Balance → Deposits in your Dashboard
• Ensure your bank info is verified
• Look for account hold/verification requests
• Remember weekend/holiday delays

4. Printer Offline or Not Printing

• Ensure the printer is powered on with paper
• Restart printer + POS device
• Verify Wi-Fi network is the same across devices
• Check the printer’s IP address in settings
• Replace worn or loose network cables

5. Square Inventory Not Syncing

• Re-enable online sync for each item
• Reconnect all devices to the internet
• Refresh item library in the Dashboard
• Check for conflicting variations

6. Square POS App Freezing or Slow

• Restart your device
• Update the Square POS app
