The public site explains the three things the business actually does - measure, fabricate and install - and invites a builder to request a quote.
About OpenConstruction
OpenConstruction is a job-to-cash management platform for construction and fabrication contractors — the businesses that quote work, cut and assemble it in a workshop, then deliver and install it on site.
It covers material stock, quotes and variations, site measurements, production, delivery and installation, labour and job costing in one system, built on Drupal 11.
The platform is organised as eight modules under strict data ownership: exactly one module can create or change each record, and every other module only reads it. That rule exists because the most expensive failure in this kind of business is two parts of the system reporting the same money differently.
Stock, cost and financial ledgers are append-only — corrections are made with reversing entries, never deletions — and every change to a price, a slab, a cost or a claim is written to an immutable audit trail. Access runs across eight levels, and visibility of pricing and margin is a separate flag on the account rather than a role, so a supervisor can approve production without seeing what the job is worth.
Key Features
Use Cases
See how OpenConstruction fits your industry
Stone & Surface Fabrication
Track slabs and off-cuts by warehouse location, reserve material against a job, and reconcile what was actually cut against what was planned.
Joinery & Custom Manufacturing
Quote from site measurements, drive the workshop from staged work orders, and hand over with photographs and a signature.
Trade Contractors with a Workshop
Run quoting, production and installation on one record instead of three spreadsheets that disagree with each other.
Fit-out & Installation Businesses
Manage several delivery visits per job, hold the job open until the punch list clears, and issue a warranty you can trace.
Technology Stack
What Makes OpenConstruction Different
One writer per record — no two modules can report the same money differently
Append-only ledgers: a correction is a reversing entry, never a deletion
Off-cuts stay valued, findable stock with parent lineage instead of becoming scrap
Warranty certificates trace a job down to the component, the slab and the goods receipt it came from
Pricing and margin visibility is an account flag, not a role — production can be approved without exposing job value
