Why Payment Processing Matters
Direct Cost Impact on Profitability
Payment processing fees represent one of your largest operating expenses. For a business processing $500,000 annually, the difference between a 2.9% and 2.2% effective rate equals $3,500 in annual savings.
Cash Flow and Business Operations
Payment timing significantly affects business operations. Traditional processors may hold funds for 2-5 business days, while modern providers offer next-day or even same-day funding.

Interchange is the fee charged by card-issuing banks for processing transactions. These fees typically range from 1.3% to 3.3% plus a fixed fee.
How can I reduce my payment processing fees?
Switch to interchange-plus pricing for transparency, negotiate better rates based on volume, encourage debit card usage, and implement fraud protection.
Can I negotiate payment processing rates?
Yes, especially if you process substantial volume. Businesses processing over $100,000 monthly should always negotiate.
What's the best processor for my small business?
For businesses processing under $10,000 monthly, Square or PayPal offer simplicity. For $10,000-$100,000, interchange-plus processors like Payment Depot or Stax typically deliver better value.
