Invoicing is a critical component of any business, ensuring that payments are tracked, managed, and received in a timely manner.

And while many cloud-based solutions are available, self-hosted invoicing apps offer greater control, customization, and often enhanced privacy. Plus many of them are open sourced and free.

That said, in this article we'll compare some of the best self-hosted invoicing apps, highlighting their key features, benefits, and potential drawbacks.

But first, let me go a bit further in depth why one would pick a self-hosted solution over a cloud-based option:

Why choose self-hosted invoicing apps over cloud options?

Paid hosted invoicing solutions like FreshBooks, QuickBooks Online, and Xero offer convenience, automatic updates, and customer support.

They're often the go-to choice for businesses that prioritize ease of use and are willing to pay for a subscription service.

However, self-hosted invoicing apps present several advantages:

1. Cost savings:

• Hosted solutions: Monthly or annual subscription fees that can add up over time.
• Self-hosted solutions: Typically free or one-time purchase costs, with expenses mainly for hosting and maintenance.

2. Data privacy and control:

• Hosted solutions: Data stored on third-party servers, potentially subject to data breaches and access by the service provider.
• Self-hosted solutions: Complete control over data, stored on your own servers, enhancing privacy and security.

3. Customization:

• Hosted solutions: Limited to the features and customizability offered by the provider.
• Self-hosted solutions: Greater flexibility to customize features and integrations to suit specific business needs.

4. No vendor lock-in:

• Hosted solutions: Dependence on the provider's infrastructure and policies.
• Self-hosted solutions: Freedom to switch hosting providers or modify the software without restrictions.
