Rabio

Rapid Business Information Organizer

RABIO is a free, open source budgeting software solution built specifically for cost control, using a Cost Breakdown Structure (CBS) to organize Budget, Actual Costs, Earned Value and Forecast in one place. It's the tool a Cost Control Department reaches for when a spreadsheet stops being enough — especially on construction and other project-based work, where costs need to be tracked center by center, category by category, from day one of the project to close-out.

The rabio_2026_09 release is now available for download, and it's the most significant update to the Open Source edition since rabio_2023_03. We compared both packages file by file — here's exactly what changed for Open Source users.

1. Reports That Finally Render Correctly Every Time

The single biggest fix in this release: PDF report export. In the 2023 edition, wide cost-breakdown tables could overlap, clip digits, or wrap header text mid-word once a project had more than a handful of centers and categories. This release rebuilds the PDF layout engine so that:

• Page size (A4 or A3) is selected automatically based on how many columns a report needs — no more manually guessing which size will fit.
• Column widths are calculated from the actual rendered font metrics, not an assumed font, so numbers and bold headers never get clipped or overlap again.
• Long header labels wrap cleanly between words instead of splitting a word in half.

If your team gave up on exporting Budget vs Actual reports to PDF because the output looked broken, this release is the reason to try again.

2. Simpler, More Consistent Report Output

To keep the Open Source edition focused and predictable, report output has been simplified:

This removes the combinations that were most prone to formatting issues, so every report a Cost Controller pulls out of RABIO Open Source looks right the first time.

3. Modern, Up-to-Date Front-End Libraries

Every vendored front-end library ships fully updated — no CDN dependency, still works completely offline:

We deliberately kept Font Awesome on the 6.x line rather than jumping to a newer major version — some of the icon names RABIO's interface relies on are only guaranteed to exist as aliases in 6.x, so staying there avoids any risk of a broken icon after upgrading.

4. A Faster, Simpler Installation

Setting up a new RABIO Open Source install used to mean importing two separate SQL files in the right order. Not anymore:

• Database structure and required reference data are now combined into a single database/rabio.sql file — one import command and you're done.
• System requirements have been refreshed and clarified: PHP 8.1+ (tested against 8.3) and MySQL 5.7+ / MariaDB 10.2+.
• Installation instructions now explicitly cover a step that's easy to miss but breaks the app under modern PHP if skipped: pointing rb_bootstrap.php at the correct path via .htaccess.

Note for anyone upgrading from rabio_2023_03: the folder structure has changed (the old application/ wrapper folder is gone), so this is a fresh install into a new directory, not a file copy-over. Point the new install at your existing database and you keep all your historical cost data.

5. Real Documentation, Finally

The release now ships with a proper README.md and a full CHANGELOG.md, so both new users and anyone upgrading from an older release can see exactly what's inside the package and what changed, without digging through commit history.

Why RABIO Is the Right Budgeting Software for Cost Control

Unlike a generic accounting tool or a spreadsheet template, RABIO is purpose-built around the Cost Breakdown Structure methodology that cost controllers already think in: centers and categories, Budget vs Actual Costs, Earned Value, and Forecast, all connected so that variance is visible at a glance rather than recalculated by hand every month. That makes it a natural fit for:

• Construction cost control — tracking budget vs. actual spend by work package, from earthworks and structural frame through finishes.
• Project-based cost management in any industry where a Cost Control Department needs to report Budget, Actual Costs, Earned Value and Forecast on the same structure.
• Teams that want an open source starting point — no license fees, full access to the code, and a clear upgrade path to Pro when the project grows.

What's New in RABIO Pro

Alongside this Open Source update, RABIO Pro has also gained a significant new capability aimed at teams managing more than one project at a time: Manage Projects.

• Create a new project from scratch, with its full cost-breakdown scaffolding set up automatically.
• Copy an existing project into a brand-new one — including its complete structure and its recorded cost history — the fastest way to start a new job that follows the same cost breakdown as a previous one.
• Delete a project safely, with a clear preview of exactly what will be removed before anything is confirmed.

Because this touches financial structure across an entire organization, access is locked down accordingly: Manage Projects is available only to super administrator users, and every action requires the super admin to re-enter their password before it takes effect — an extra layer of protection against an unattended session being used to create, duplicate, or remove a project by mistake.

This feature is exclusive to RABIO Pro, which also includes multi-project geo-mapping, file attachments, approval workflows, and extended reporting on top of everything in the Open Source edition. If your team is outgrowing a single-project setup, or you need a custom feature built for your specific cost control process, get in touch with the RABIO team about upgrading or custom development.
