v7.6.0 - a built-in general ledger, AI plan reading and room for much larger files.

OpenConstructionERP is used by people in more than 100 countries, and a large share of what we ship starts as one of your messages. Version 7.6.0 follows the same line as 7.5.0, the full path from a drawing to a calculated and scheduled project, and adds two things many of you asked for: a real set of books your project costs roll up into, and the room to work with the large files and long lists that real projects produce.

What is new in version 7.6.0

• A double-entry general ledger. A chart of accounts, balanced journal entries, and a trial balance, income statement, balance sheet and cash flow built from the same postings.
• AI plan reading for PDF takeoff. The takeoff tool can read a drawing with a vision model and propose what it finds as labelled suggestions you confirm, with every billed quantity re-derived on the server.
• Resumable uploads for large CAD and PDF files. A big upload goes up in chunks and picks up where it left off if the connection drops, instead of starting over.
• Higher limits across the board. Bigger uploads, longer lists per page and larger bulk actions, so big projects do not run into a ceiling.
• Self-service account erasure and saved views. You can remove your own account and data from Settings, and save a filtered, sorted view of a list to reopen later.

Your project costs, in a real set of books

Estimates, budgets, commitments and actuals already share one cost line in OpenConstructionERP. Version 7.6.0 takes the next step and posts them into a proper general ledger. You get a chart of accounts, and every entry is a balanced double-entry journal that is checked to balance before it posts, so debits and credits always tie out. From those postings the platform builds the four statements you expect: a trial balance, an income statement, a balance sheet and a direct-method cash flow. It is the financial backbone that turns project cost data into numbers a finance team can read, without exporting to a separate accounting tool.

AI that reads the plan, and you decide

Quantity takeoff already reads vector drawings and, since 7.5.0, scanned ones. In 7.6.0 the takeoff tool can also hand a PDF plan to a vision model and get back what it sees as labelled suggestions: rooms, lines and counts you confirm or correct. Nothing is applied on its own. The suggestion is a starting point, you stay in control of every measurement, and the server re-derives the billed quantity on save so an AI reading can never quietly change a number.

Built for the size of real projects

Large models and long bills of quantities should not hit an arbitrary wall. This release raises the limits across uploads, pagination and bulk operations, and adds resumable uploads so a multi-gigabyte CAD or PDF file goes up in chunks and resumes after a dropped connection instead of starting from zero. The one limit we deliberately left alone is the sign-in rate limit, which stays where it is to keep accounts safe.

Your data, on your terms

OpenConstructionERP is open-source and self-hosted, and your data belongs to you. Version 7.6.0 makes that concrete with self-service account erasure: you can remove your own account and personal data from the Settings danger zone, with a clear confirmation first. A hardening pass across twelve modules also tightened how amounts are calculated and how each request stays inside the right workspace, so the numbers stay correct and the boundaries stay firm.

By the numbers

Install or upgrade

pip install --upgrade openconstructionerp

The desktop installers for Windows, macOS and Linux carry the same one-installer setup, and the Linux build includes the CAD and BIM converters for AutoCAD, Revit and IFC. You can grab the latest installers from openconstructionerp.com/download. If you run an external PostgreSQL through DATABASE_URL, nothing about that connection changes.
