Spendline provides AI cost attribution and budget controls for B2B software companies. It sits between an application and supported AI providers.
Your application supplies customer and workflow labels. Spendline records the attributed cost and checks configured budgets before forwarding supported requests. Where you share revenue data, it compares customer revenue with AI cost for the same period. Other delivery costs are not included.
Start with one workflow in a guided 30-day free pilot on live production traffic. We agree the scope, success criteria and paid terms before you start.
