Most invoicing tools rent themselves back to you every month. SolidInvoice is yours, fork the code, host it on your own server, and keep your billing data under your control.
Don't want to run servers?
We host it from $9/mo. Same codebase. Free 14-day trial, no credit card.
The honest reasons. Open source isn't just a checkbox, it changes what you can do with the software.
Invoice data lives on hardware you control. No third party holds the keys. Fits compliance needs (GDPR, HIPAA-adjacent workflows, internal policy) without custom contracts.
MIT licensed since 2013. Add fields, change workflows, integrate with your existing tools. No feature-request queue, just open a PR or patch it yourself.
If the hosted product disappeared tomorrow, your install keeps running. Export your data in SQL, CSV, or PDF at any point.
If you run Docker, Postgres, and a reverse proxy already, SolidInvoice is another container in your stack. Marginal cost is close to zero.
The software is free. Running it isn't quite free. Here's what a year actually looks like, so you can make the call.
Worth it if: you value control, already run infra, or bill hourly enough that your time isn't a constraint.
Worth it if: your time is worth more than $10/hr and you'd rather invoice clients than patch servers.
Start self-hosted and switch to hosted later if you want. Your data moves with you, that's the whole point of open source.
Docker is the shortest path. Other methods on the download page.
docker run -d -p 8080:8765 solidinvoice/solidinvoice:latestCommits, issues, and discussions are all public. Kick the tyres before you commit to anything.
We run it from $9/mo, same features, same MIT codebase. Switch to self-hosted whenever you want; your data moves with you.
