What Is Credit Card Payment Processing?
Credit card payment processing is the service that allows businesses to accept payments made with credit and debit cards. It involves a series of steps that connect the customer’s bank to the merchant’s account, ensuring the transaction is secure and funds are transferred correctly.
Here’s a basic overview of how it works:
- Customer swipes, taps, or enters card info.
- The payment gateway sends this data to the processor.
- The processor contacts the card network (Visa, Mastercard, etc.).
- The issuing bank approves or declines the transaction.
- If approved, the funds are held temporarily before being deposited into the merchant’s bank account (usually within 1–2 business days).
Key Factors to Consider When Choosing a Payment Processor
Choosing the right credit card processing service requires evaluating several critical features. Here are the most important ones:
1. Pricing & Fees
- Transaction Fees: Usually a percentage + a flat fee (e.g., 2.6% + $0.10).
- Monthly Fees: Some providers charge monthly or annual fees.
- Setup Fees & Termination Fees: Be wary of long-term contracts.
2. Ease of Use
- Intuitive dashboards, simple onboarding, and user-friendly hardware/software make a big difference for small business owners.
3. Payment Methods Supported
- In-person, online, mobile, contactless (NFC), invoicing, recurring billing, etc.
4. Hardware and Software Integration
- Does it work with your POS system, accounting software (QuickBooks, Xero), or ecommerce platform?
5. Customer Support
- 24/7 support is crucial for handling transaction issues, disputes, or technical problems.
6. Payout Speed
- Faster payouts help with cash flow—some processors offer next-day or even same-day deposits.
