Custom pricing allows vendors to offer enterprise customers bespoke pricing that reflects their specific needs, committed usage, and negotiating power. It is common in B2B SaaS for deals that fall outside standard packaging.

Example: A SaaS vendor's standard plans top out at $2,000/month. An enterprise customer negotiating for 500 seats, a 3-year term, and custom SLAs receives a custom pricing proposal of $15,000/month, developed specifically for their requirements.
