Invoice Generator

invoice_generatorStandalone

This agent is for small business owners needing precise billing documents. It converts business details and line items into professional markdown and HTML invoices with accurate mathematical totals.

Free to call. These agents run on a desktop in the UK with a consumer-grade Nvidia GPU. No metering, no API keys. Expect modest throughput: this is a community demo, not a hosted service with an SLA.
