Why you should use Square Payment

Why you should use Square Payment

Square Payments simplifies the process of accepting all forms of payment for small enterprises without splitting the bank. They acknowledge that no small enterprise should be excluded from the economy due to prohibitively high costs or complex technologies. These are five reasons why you should connect Square Payment with your existing BigCommerce store.

  • Simple Flat Rate Payment Processing: Square can be used to process credit card purchases in your physical store, online, and on the go using your mobile device. Per credit card purchase, Square charges a flat fee. The credit card company fee, the customer’s bank cost, and the merchant account processor fee are rolled into one flat-rate fee.
  • Top merchant services: One of the best merchant systems available for small businesses is Square’s inexpensive and user-friendly payment processing. Any free Square account includes invoicing, a virtual console, online orders, and software to track and challenge chargebacks, in addition to smartphone and in-store payments.
  • Free & Low-Cost POS Software: Square provides free and premium POS platform subscriptions for grocery, hotel, and appointment-based companies in addition to the regular free Square POS app. Pay collection, inventory control, basic workforce management, customer relationship management (CRM), monitoring, and analytics are also included with each POS software product, as well as industry-specific functions.
  • Free Online Ordering Website Builder: Any Square account comes with a third free solution, Square Online. It’s a simple site builder that you can use to make a company website, a basic eCommerce site, or add online shopping or order-ahead features to your existing business. Square Online can also be used to schedule appointments online. Business Management Solutions: Square provides a variety of market management applications that can be used as a standalone platform or in combination with any of Square’s other offerings, in addition to its three free business tools: purchases, POS, and online shop. One of the benefits of using Square is that companies can mix and match which technologies they need to build the right configuration for their requirements.

You’ll be able to hold a correct inventory count in your BigCommerce account until you’ve set up your Square Point of Sale and BigCommerce. Both order-based stock level changes are now reflected in real-time in your BigCommerce account. Note that while manually updating stock levels in BigCommerce would immediately move to your Square account, any manual changes in your Square account will not.

BONUS: Some important things that you have to consider once deciding to connect Square to your BigCommerce store:

  • Payments collected by BigCommerce will appear in your Square Dashboard’s transaction history and will be used in your Transaction CSV. Access your BigCommerce account to track your orders and issue refunds.
  • Your customers will get an email confirmation from BigCommerce when they put an order on your BigCommerce store. Customers will not get Square receipts immediately, but you will issue a Square receipt at any time from the online Square Dashboard. Your BigCommerce orders will be transferred according to your transfer plan, much like Square Point of Sale purchases.

Note: BigCommerce and Square Inventory are also integrated.
