Real-Life Example:
How Lisa Uses Merchant Services to Grow Her Bakery
Lisa owns a small bakery in Austin, Texas. She sells pastries at her shop and occasionally at weekend farmer’s markets. She chose Square for her business because:
- She needed a mobile card reader she could use on her phone.
- Square didn’t charge monthly fees — she only pays per transaction.
- The software includes inventory tracking and customer insights.
As a result, Lisa doubled her weekend sales by offering card payments and sped up checkout in her store.
How Do Merchant Services Work?
Here’s a simple version of what happens when a customer pays you with a card:
- You collect the payment using a reader, a POS system, or a website.
- The transaction is sent to the payment processor.
- The processor checks with the customer’s bank for approval.
- If approved, the funds are sent to your merchant account.
- Within 1–3 days, the money is transferred to your business bank account, minus a small fee.
