Payment Processing Fundamentals

What exactly is payment processing?

Payment processing is the system that moves money from your customer’s account to your business account when they make a purchase. Think of it as the digital equivalent of handling cash, but with multiple parties working together to ensure the transaction is secure and legitimate.

The key players involved:

• Payment Gateway: Captures and encrypts payment information from your website or terminal
• Payment Processor: Routes transaction data between banks and card networks
• Acquiring Bank: Your business’s bank that receives the funds
• Issuing Bank: Your customer’s bank that issued their payment card
• Card Networks: Visa, Mastercard, American Express, and Discover

How does a payment transaction actually work?

Here’s what happens in the few seconds between when your customer submits payment and when you get confirmation:

1. Customer submits payment – Card information entered online or swiped/inserted at terminal
2. Encryption and routing – Payment gateway encrypts data and sends to processor
3. Authorization request – Processor asks customer’s bank to approve the transaction
4. Bank response – Customer’s bank approves or declines based on available funds/credit
5. Merchant notification – You receive approval or decline message instantly
6. Settlement – Approved funds transfer to your account (typically 1-3 business days)

What payment methods should I accept?

Most merchants should accept these core payment methods:

Credit Cards (Essential)

• Visa and Mastercard (accept 85%+ of US transactions)
• American Express (higher fees but affluent customer base)
• Discover (rounds out major card acceptance)

Debit Cards (Essential)

• Lower processing costs than credit cards
• Instant payment for customers
• Preferred by budget-conscious shoppers

ACH/Electronic Checks (Recommended for B2B)

• Lowest processing costs (typically under 1%)
• Perfect for recurring payments and large transactions
• Standard for business-to-business payments

Digital Wallets (Increasingly Important)

• Apple Pay, Google Pay, Samsung Pay
• PayPal, Venmo (for online transactions)
• Faster checkout, improved security
• Preferred by mobile users

IntelliPay helps merchants determine the optimal payment mix based on their customer demographics and transaction patterns. Contact us at intellipay.com for personalized recommendations.

Cost and Fee Questions

How much will payment processing cost my business?

Processing costs vary based on your business size, industry, and the types of payments you accept. Here’s what to expect:

Typical Processing Rates by Business Size:

• Small businesses ($100K-$250K annually): 2.9% – 4.2% per transaction
• Medium businesses ($250K-$1M annually): 2.5% – 3.5% per transaction
• Large businesses ($1M+ annually): 1.8% – 2.8% per transaction

Rate Factors That Affect Your Costs:

• Card type: Debit cards cost less than credit cards
• Transaction method: In-person transactions cost less than online
• Card rewards level: Premium rewards cards cost more to process
• Business risk level: High-risk industries pay more
• Monthly volume: Higher volume typically means better rates

IntelliPay offers transparent rate analysis to help you understand exactly what you’ll pay. Visit intellipay.com for a free cost assessment.

What are interchange fees, and why do they matter?

Interchange fees are non-negotiable rates set by card companies (such as Visa and Mastercard) that account for approximately 80% of your total processing costs. Every processor pays the same interchange rates—the difference is in what they charge on top of these base costs.

2025 Interchange Examples:

• Visa/Mastercard Debit: 0.05% + $0.21
• Basic Credit Cards: 1.51% + $0.10
• Rewards Credit Cards: 1.65% – 2.40% + $0.10
• Business/Corporate Cards: 2.20% – 2.95% + $0.10

Why this matters: Since interchange is the same everywhere, focus on finding a processor with the lowest markup above these base costs.

What pricing models do processors offer?

1. Interchange-Plus Pricing (Best for most businesses)

• You pay exact interchange costs + a clear processor markup
• Most transparent option
• Typical markup: 0.10% – 0.50% + $0.05-$0.15 per transaction
• IntelliPay uses in interchange-plus pricing for maximum transparency

2. Flat-Rate Pricing (Good for low volume)

• One rate for all transactions (e.g., 2.9% + $0.30)
• Simple but often more expensive for high-volume merchants
• Good if you process less than $5,000/month

3. Tiered Pricing (Generally avoid)

• “Qualified,” “mid-qualified,” and “non-qualified” rates
• Often confusing and expensive
• Difficult to predict actual costs

4. Membership Pricing (Consider for high volume)

• Monthly fee + cost-plus pricing
• Can be cost-effective if you process $50,000+/month
• Requires careful analysis to ensure savings

What hidden fees should I watch for?

Common fees that processors don’t always highlight upfront:

Monthly Fees:

• Gateway fees: $15-$25/month
• Statement fees: $10-$15/month
• PCI compliance fees: $5-$15/month
• Minimum processing fees: $25-$50/month

Per-Transaction Fees:

• Batch settlement: $0.10-$0.25 per batch
• Authorization fees: $0.10-$0.20 per attempt
• International card fees: 1%-3% additional

Incident Fees:

• Chargeback fees: $15-$50 per chargeback
• NSF/returned payment fees: $25-$50
• Account update fees: $0.10-$0.25 per card update

Contract Fees:

• Setup fees: $0-$500
• Early termination fees: $200-$500
• PCI non-compliance fines: $20-$100/month

How can I reduce my processing costs?

Immediate Cost-Saving Strategies:

1. Negotiate Better Rates
   • Compare multiple processors annually

   • Ask specifically for interchange-plus pricing
   • IntelliPay’s industry relationships often secure better rates for our clients
2. Optimize Your Transaction Mix

   • Process transactions promptly to avoid declines
4. Consider Legal Surcharging
   • Pass credit card fees to customers (where legal)
   • Must clearly disclose surcharge amounts
   • Cannot exceed actual processing costs
   • Contact IntelliPay for guidance on surcharging compliance in your state
5. Choose Cost-Effective Equipment
   • Buy terminals instead of renting (saves $20-$50/month)
   • Use certified equipment to avoid non-compliance fees
   • Consider mobile solutions for lower-volume locations

Security and Compliance

What is PCI compliance, and do I need it?

PCI DSS (Payment Card Industry Data Security Standard) compliance is mandatory for any business that accepts, processes, stores, or transmits credit card information. Non-compliance can result in fines up to $100,000 per month.

PCI Compliance Levels Based on Transaction Volume:

• Level 1: 6+ million transactions/year → Full security assessment required
• Level 2: 1-6 million transactions/year → Annual self-assessment questionnaire
• Level 3: 20,000-1 million e-commerce transactions/year → Annual self-assessment
• Level 4: Under 20,000 transactions/year → Annual self-assessment questionnaire

Core PCI Requirements:

• Maintain secure networks with firewalls
• Never store sensitive authentication data (CVV codes, etc.)
• Encrypt transmission of cardholder data across open networks
• Use and regularly update anti-virus software
• Restrict access to cardholder data on need-to-know basis
• Assign unique ID to each person with computer access
• Regularly test security systems and processes

Red Flags to Monitor:

• Multiple transactions with different cards from same IP address
• Shipping address is different from billing address
• Large orders from new customers
• Transactions just under your authorization limits
• Orders from high-risk geographic locations

What happens if I get a chargeback?

A chargeback occurs when a customer disputes a charge through their bank, forcing you to prove the transaction was legitimate.

Common Chargeback Reasons:

• Customer doesn’t recognize the charge (unclear billing descriptor)
• Product not received or significantly different than described
• Fraudulent transaction (stolen card information)
• Customer tried to cancel but was still charged
• Processing error (duplicate charge, wrong amount)

Chargeback Prevention:

1. Use clear billing descriptors – Customer should recognize your business name
2. Provide excellent customer service – Resolve issues before they become disputes
3. Keep detailed transaction records – Save receipts, shipping confirmations, etc.
4. Process refunds promptly – Don’t make customers dispute legitimate returns
5. Communicate clearly – Ensure customers understand what they’re buying

Response Process:

• You have 7-10 days to respond with evidence
• Provide compelling documentation (receipt, delivery confirmation, customer communication)
• Win rates average 20-40% across industries
• Each chargeback typically costs $15-$50 in fees, regardless of the outcome

What’s the difference between a payment gateway and a payment processor?

Payment Gateway:

• The technology that captures payment information
• Encrypts sensitive data for security
• Provides the checkout experience for customers
• Handles fraud detection and prevention tools
• Think of it as the “digital cash register”

Payment Processor:

• The service that moves money between accounts
• Communicates with banks and card networks
• Manages the actual funds transfer
• Provides merchant accounts and banking relationships
• Think of it as the “digital bank teller”

Integration Options:

1. All-in-one solutions (IntelliPay) – Gateway and processor combined
2. Separate providers – Choose best gateway + best processor for your needs
3. Processor-provided gateway – Many processors include gateway services

How do I accept mobile payments?

Popular Mobile Payment Options:

• Apple Pay: 70%+ of eligible iPhone users enrolled, works with most terminals
• Google Pay: Growing Android adoption, NFC and online payments
• Samsung Pay: Works with older magnetic stripe terminals
• PayPal/Venmo: Popular for online and peer-to-peer transactions

Implementation Requirements:

• For in-person: NFC-enabled terminal, EMV compliance
• For online: SSL certificate, payment gateway support
• Security: Tokenization for data protection, PCI compliance

Benefits of Mobile Payments:

• Faster checkout process (15-20% improvement)
• Enhanced security through tokenization
• Better customer experience
• Reduced cart abandonment online
• Appeals to younger demographics

Should I accept ACH/electronic check payments?

ACH payments can significantly reduce your processing costs, especially for larger transactions or B2B payments.

ACH Benefits:

• Lower costs: Typically 0.5% – 1% vs. 2.9%+ for cards
• No chargebacks: ACH returns are much less common and easier to resolve
• Perfect for recurring payments: Subscriptions, memberships, loan payments
• Higher transaction limits: No practical limit like credit cards

ACH Considerations:

• Slower processing: 1-3 business days vs. instant authorization
• Customer setup: Requires bank account information
• Return risk: Payments can be returned for insufficient funds
• NACHA compliance: Must follow ACH network rules

Best Use Cases for ACH:

• Monthly subscriptions or memberships
• Large purchases ($500+)
• B2B invoice payments
• Rent, utility, or loan payments
• Any situation where lower costs outweigh slower processing

Frequently Asked Questions

Q: How often should I review my payment processing costs? A: Review annually for rate negotiations, quarterly for optimization opportunities. Processing costs are often your second-largest expense after payroll.

Q: Can I switch payment processors without disrupting my business? A: Yes, with proper planning. Allow 2-4 weeks for transition and always maintain backup payment methods during the switch.

Q: Do I need a separate solution for online and in-person payments? A: Not necessarily. Many processors offer unified solutions, but some businesses benefit from specialized solutions for each channel.

Q: What’s the difference between payment aggregators and traditional merchant accounts? A: Aggregators (Stripe, Square) pool multiple merchants under one account—quick setup but less control. Traditional merchant accounts offer individualized identification and often provide better rates for established businesses.

Q: How do I handle international customers? A: Look for processors with global capabilities, multi-currency support, and local payment methods for international markets.
