Invoice

Invoice is a command-line application for generating professional invoices as PDF files. Users can specify sender and recipient information, line items, quantities, rates, taxes, discounts, and notes directly through terminal options. The generated PDF can be saved to a custom output location. Frequently reused business information can be stored in environment variables to reduce repetitive input. Invoice data can also be defined in JSON or YAML configuration files and imported during generation. The tool is written in Go and can be installed with the Go toolchain or downloaded as a compiled binary.
