Authorize.net and peers: monthly-fee + per-transaction pricing model — the pre-Stripe norm

Claim: Authorize.net and peer payment gateways operated on a monthly fee + per-transaction pricing model (~$10–$25/month base + per-transaction). This was the norm before Stripe normalized all-transactional, zero monthly pricing.

Source: Multiple payment-industry sources.

Confidence: Verified.

Why this matters for Candid: The pricing-model contrast (Stripe pricing: 2.9% + 30¢ per successful domestic card transaction; no monthly, setup, or cancellation fees) is part of why Stripe is the canonical commodity-parts example. A storefront with light traffic was paying $25/month for the gateway whether or not it sold anything — a fixed cost that scaled poorly to zero.
