What is AI Invoice Generation?
In plain language
AI invoice generation uses language models to transform technical work context — PR titles, descriptions, issues, and diffs — into professional invoice line items. Instead of writing "refactored auth middleware," the AI produces "improved authentication architecture for better security and maintainability."

Dedicated tools like diffbill automate the entire workflow — gathering PRs, providing context, generating descriptions, and creating Stripe drafts — instead of requiring manual prompting each time.
