What are practical scenarios where custom pricing shines?

A global e-commerce brand running 12 regional storefronts, each with its own domain, needing translation into 30 languages and bot-refund reporting for Google Ads. An agency managing 50 client sites that wants a single master contract, centralized admin, and the ability to activate agents per client without separate sign-ups. A high-volume lead-gen site spending over $200k per month on paid traffic, requiring bot detection, refund evidence, and conversion-lift guarantees before any invoice.
