Frequently Asked Questions
01 What is interchange++ pricing and why do enterprises use it?
Interchange++ pricing separates the processor's fee from the card network's interchange fee, providing full transparency. Enterprises pay interchange (set by Visa/Mastercard, typically 1.5-2.5%) + a small processor markup (0.5-0.8%) + card scheme fees (0.1-0.15%). This typically saves 0.5-1% compared to flat-rate pricing like Stripe's 2.9% at high volumes, translating to millions in savings on $100M+ annual processing.
02 How much volume do I need to qualify for enterprise payment pricing?
Adyen typically requires $10M+ annual volume ($800K+ monthly), Checkout.com starts at $5M+ annual ($400K+ monthly), and Stripe offers custom enterprise pricing at $1M+ monthly. Below these thresholds, standard pricing from Stripe or Braintree is often more cost-effective when factoring in setup complexity and integration costs.
03 What is smart payment routing and how much does it improve authorization rates?
Smart payment routing automatically selects the optimal payment network, acquirer, or processing path for each transaction based on real-time data. Adyen's routing improves authorization rates by 2-5% on average, while Checkout.com claims up to 8% improvement. For a $100M annual business, a 3% improvement in authorization means $3M in recovered revenue, often exceeding the total processing fees saved by switching processors.
04 Should enterprises use a single processor or multi-processor strategy?
Large enterprises often use multi-processor strategies for redundancy and leverage. A primary processor (Adyen or Stripe) handles 80-90% of volume, while a backup (Checkout.com or Braintree) provides failover during outages and pricing negotiation leverage. However, this requires sophisticated integration and monitoring. Most mid-sized enterprises are better served by a single processor until $50M+ annual volume.
05 How do payment processors impact global expansion speed?
Processors with local acquiring (Adyen, Checkout.com) can launch in new countries in days by processing payments through local entities, improving authorization rates by 5-10% versus cross-border processing. Stripe requires more integration work per market but offers faster setup in major markets. Adyen's single contract covering 200+ countries is fastest for aggressive global expansion, while Stripe is faster for US/EU-focused growth.
06 What's the difference between free and paid tiers?
Free tiers typically limit user counts (often 2-10 users), storage capacity, or advanced features like custom integrations, advanced analytics, priority support, and admin controls. Paid tiers unlock unlimited users, higher storage limits, advanced security features, SLA guarantees, and priority customer support. Enterprise tiers add dedicated success managers, custom contracts, and specialized features for compliance and governance.
