## What it is
Invio is a self-hosted, open-source invoicing application built in TypeScript with a minimalist, zero-bloat philosophy. Users create invoices, share secure links with clients (no client accounts needed), and get paid while keeping all data on their own hardware.

## Use cases
- self-host my invoicing instead of paying for SaaS
- create and send invoices to clients without them needing an account
- generate shareable invoice links for clients
- keep client and payment data on my own server
- simple minimalist invoicing for freelancers
- replace bloated invoicing software with a lightweight tool

## When to choose
- you want full ownership of your invoicing data on your own hardware
- you need a simple, no-frills invoicing tool without subscriptions or per-invoice fees
- your clients should be able to view invoices via a secure link without signing up
- you prefer free and open-source software with a minimalist workflow

## When to avoid
- you need advanced accounting features like taxes, multi-currency reporting, or bookkeeping integrations
- you want a managed hosted solution with support rather than self-hosting
- you require team collaboration, approval workflows, or ERP-level invoicing features
