## Frequently Asked Questions (verified answers)
Q: What is flat-rate pricing for payment processing?
A: Flat-rate pricing charges one fixed percentage on every transaction regardless of card type — Stripe and Square use this model. It's simple and predictable but can be more expensive than interchange-plus for high-volume businesses. The simplicity is worth it for small businesses that prioritize ease...

Q: What are assessment fees in payment processing?
A: Assessment fees are charged by the card networks (Visa, Mastercard, Amex, Discover) directly to processors, who pass them to merchants. They're small — typically 0.13% to 0.15% — but unavoidable on every transaction. Unlike interchange, assessment fees are the same regardless of your processor and a...

Q: What happens when a customer swipes a card?
A: Swiping triggers an authorization request: your POS sends card data to your payment processor, which routes it through the card network to the issuing bank. The issuing bank checks available credit or balance and returns an approval or decline code. The actual money movement happens in a separate ba...

Q: What is interchange-plus pricing?
A: Interchange-plus passes the exact interchange rate through to you, plus a fixed markup from your processor (e.g., interchange + 0.3% + $0.10). This is the most transparent pricing model because you see exactly what Visa/Mastercard charges versus what your processor keeps. It's usually best for busin...

Q: What is tiered pricing and should I avoid it?
A: Tiered pricing sorts transactions into "qualified," "mid-qualified," and "non-qualified" buckets with different rates. The processor decides which tier each transaction falls into, often pushing rewards cards into the most expensive tier. Most payment experts recommend avoiding tiered pricing becaus...

Q: What does "2.9% + $0.30" actually mean?
A: On a $100 sale, you pay $2.90 (2.9%) plus $0.30 flat, keeping $96.80. The percentage covers interchange and processor margin; the fixed $0.30 covers authorization costs. The flat fee makes this proportionally expensive for small transactions — on a $5 sale you pay roughly 9% effective rate — so it f...

Q: How much does Square charge per transaction?
A: Square charges 2.6% + $0.10 for in-person card swipes, dips, and taps; 3.5% + $0.15 for manually keyed transactions; and 2.9% + $0.30 for online payments. There are no monthly fees on the free plan. Paid plans (Square Plus at $29/month) reduce rates for high-volume sellers in categories like restaur...

Q: How does payment processing actually work?
A: When a customer swipes or taps their card, the transaction travels from the merchant's terminal to their acquiring bank, through the card network (Visa/Mastercard), to the customer's issuing bank for approval, then back. The whole process takes 1-3 seconds. Funds typically settle to your bank accoun...

Q: What is interchange and who sets it?
A: Interchange is the fee paid to the customer's card-issuing bank on every transaction. Visa and Mastercard set interchange rates, which vary by card type, transaction type, and merchant category. Rewards cards and business cards carry higher interchange than basic debit. Interchange is the largest co...

Q: Is Square good for restaurants?
A: Square for Restaurants offers tableside ordering, menu management, floor plan layout, and kitchen display integration. The free plan works for simple cafes; the $60/month plan adds multi-location support and advanced reporting. Toast is a stronger choice if you need complex modifier trees or deep ki...
