How to Enable Bitcoin Payments for Your Square Business and Join the Million Merchant Club
Introduction
Square, now part of Block Inc., recently announced that over 1 million merchants are enabled to accept Bitcoin payments — a milestone driven by automatic enrollment for eligible U.S. sellers starting March 30. This guide walks you through how to join them, leveraging the Lightning Network for fast, low-cost transactions while receiving settlements in U.S. dollars. Whether you're a new Square user or an existing merchant, you'll learn the simple steps to start accepting Bitcoin as everyday money — just like the million businesses already on board.
What You Need
- An active Square account (for payment processing)
- Eligibility as a U.S.-based seller (currently limited to U.S. merchants)
- Access to your Square Dashboard (online or mobile app)
- Optional: A Square hardware terminal with NFC capability (for tap-to-pay Bitcoin)
- Understanding: No separate Bitcoin wallet required — Square handles conversion automatically
Step-by-Step Guide
Step 1: Log in to Your Square Dashboard
Navigate to squareup.com and log in using your merchant credentials. If you don’t have a Square account yet, sign up for free. Once logged in, you will see your main dashboard with options for settings, payments, and reports.
Step 2: Locate the Bitcoin Payments Toggle
Go to Settings > Payments > Bitcoin. If your account is eligible, you will see a toggle labeled “Accept Bitcoin payments.” For many U.S. sellers, this toggle was automatically turned on as of March 30, 2025. If it’s already enabled, you’re all set — skip to Step 4 to understand how payments work. If not, proceed to Step 3.
Step 3: Manually Enable Bitcoin Acceptance
If the feature is available but not yet active, simply toggle the switch to “On.” Square will ask you to confirm. Once enabled, your business becomes part of the network that activates a new Bitcoin-ready merchant every eight seconds. Note: You can opt out at any time by toggling it off.
Step 4: Understand How Bitcoin Payments Work
When a customer pays with Bitcoin via the Lightning Network, the transaction is processed almost instantly. Square automatically converts the BTC into U.S. dollars and deposits the USD amount into your regular settlement account. This means you never hold Bitcoin — you avoid price volatility and currency risk. Customers see a simple BTC payment option; you see a normal USD payment. It’s that seamless.
Step 5: Offer Tap-to-Pay Bitcoin (with NFC Hardware)
If you use Square’s contactless-enabled card readers or terminals (e.g., Square Reader or Square Terminal), customers can tap their NFC-enabled Bitcoin wallets to pay. No QR codes needed. This feature is powered by the Lightning Network and comes with zero processing fees through 2026 — a great incentive to encourage Bitcoin usage.
Step 6: Leverage Cash App Integration for Rewards
Encourage customers who use Cash App to send Bitcoin payments. Your Square system is already compatible. Cash App users can automatically convert peer-to-peer payments into BTC and earn 5% Bitcoin Back rewards at your store. They can withdraw up to $10,000 per day and $25,000 per week. Highlight these benefits to attract more Bitcoin-savvy shoppers.
Step 7: Monitor Your Bitcoin Payment Reports
In your Square Dashboard, you can view detailed reports under Reports > Payments. Filter by “Bitcoin” to see transaction volumes, fees (if any — remember, tap-to-pay is fee-free until 2026), and settlement amounts. This helps you track adoption and decide if you want to promote Bitcoin payments further.
Tips and Best Practices
- Promote Bitcoin acceptance with in-store signage or online banners. Mention that customers can pay with any Lightning-enabled wallet and receive instant confirmation.
- Test the process by making a small purchase with your own Lightning wallet (e.g., Wallet of Satoshi or Phoenix). This ensures everything works smoothly.
- Stay informed about updates — Block is expanding to more countries and adding features like the Bitkey hardware wallet for self-custody (though not required for merchants).
- Consider security — your Square account already follows PCI compliance. No extra steps needed, but use strong passwords and two-factor authentication.
- Leverage the proof-of-reserves report — Block holds 28,355 BTC (worth ~$2.2 billion), showing strong backing. Share this with skeptical customers to build trust.
- Opt out if needed — If you prefer not to offer Bitcoin payments, simply toggle the feature off. No impact on your other Square services.
With over one million merchants already on board, accepting Bitcoin through Square is a frictionless way to tap into the growing crypto economy. By following these steps, your business can join the movement toward making Bitcoin real-world money — one transaction at a time.
