LedgerSMB is an open-source ERP (Enterprise Resource Management) software that enables businesses to efficiently manage their operations, gives them full control over their cash flow, and lets them track and plan budgets by project and department.

The app also lets you track time spent working on different projects and enables you to easily convert billable hours into invoices.

What LedgerSMB is lacking is payroll functionality, plus its reporting capabilities are quite limited.

Free vs Open Source Accounting Software

Open-source software is typically free to use forever, but there are a few exceptions, like Odoo, which offers premium plans as well.

What’s worth noting is that most accounting software solutions that advertise themselves as free limit you in one way or another. They usually only offer free plans with limited numbers of invoices you can send or a limited number of users.

On the other side, truly open source software is free to use forever, with no limits, hidden fees, or strings attached.

So, if you’re on a tight budget, open-source software is typically the better option. However, given that these tools are mostly built by volunteer developers and are a community project in most cases, they have outdated UIs and are much more difficult to learn and fully utilize compared to free plans of premium accounting tools.
