How to Use Square to Run Your Business
In addition to payment processing, you can use Square’s mobile POS app to help run your business on the go. The following management tools are available through the app:
- Order and inventory management: Add items to your library, track in-stock inventory, and check order status. Square automatically updates your inventory when you make a sale, so your stock numbers are always up-to-date.
- Sales reports: Sales are recorded and summarized to help you track growth and make key business decisions.
- Customer management: Enter your customer information, such as email addresses and purchase history, so you can provide better service or grow your business via email marketing.
- Team member profiles: Add and view team members to quickly reference contact information.
Since your Square Dashboard is your business hub, this is where you’ll manage many of the payments-related aspects of your business. Use your Dashboard to access tools and features like:
- Team management: Add/remove employees, track clock-ins/clock-outs, view timecards, and manage breaks and overtime. Upgrade to Team Plus for $35/month to access employee activity logs and detailed sales and labor reports.
- Payroll: If you upgrade to Square Payroll, you can run payroll with direct deposits anytime, manage benefits like health care and pay-out tips, file new hire paperwork, and view federal and state tax withholdings and filings.
- Marketing: Create email campaigns for coupons, business updates, sales, and more. You can also generate automated campaigns for new customers, lapsed customers, birthdays, and more. Connect your Facebook account to set up marketing campaigns and access marketing reports.
- Reports: Pull detailed daily, weekly, or monthly sales reports and trends. Track analytics like payment methods, individual team member sales, labor vs sales, comps, voids, disputes, and taxes.
- Inventory management: Adjust and sync inventory from your mobile POS app or Dashboard. The app is great for on-the-fly changes, but any bulk uploads or adjustments, variant management, or low-stock tracking is easier on the Dashboard.
- Financial management: Monitor bank transfers, set up a Square Card (a business debit card tied to your Square sales balance), and request a business loan through Square Capital.
- Square Banking: Integrate your payments, banking accounts, and cash flow when taking payments and banking through Square. Products include Square Checking, Square Savings, and Square Loans.
