Description
Most invoicing apps start by asking you to create an account. Invoice Builder doesn’t.
It runs locally on your machine & your invoices are stored in a database file that you control.
This is an offline-first, open-source invoicing and quoting application built for freelancers, contractors, and small businesses who prefer owning their data instead of renting access to it.

PostgreSQL Support
Invoice Builder supports two database backends:
| Storage Type | Description | Best For |
|---|---|---|
| SQLite (local file) | Single portable database file stored locally | Solo users, offline desktop use |
| PostgreSQL (server) | Network-accessible database server | Multi-user setups, Docker deployments, NAS/server environments |
You can either:
- Create or open a local SQLite database file
- Connect to a PostgreSQL server using host, port, username, password, and database name
This makes it usable for both individual freelancers and small teams running it on shared infrastructure.

Conclusion
Invoice Builder is a straightforward offline invoicing tool. It doesn’t try to sync your data across the internet or bundle analytics into your financial documents.
If you want local control, open-source transparency, and flexible PDF customization, it’s worth trying.
If you prefer fully managed cloud accounting software, this probably isn’t the right fit.
