Multi-Currency BOQ And Reliable BIM Import For Construction ERP

OpenConstructionERP is an open-source construction ERP handling bills of quantities and BIM and CAD imports, reaching 350 GitHub stars with an internationally distributed user base, and its issues pinpoint the two things estimators on cross-border projects need: a single budget that supports multiple currencies cleanly, and IFC model uploads that do not silently fail to zero elements after appearing to succeed. International contractors estimate in mixed currencies from BIM models. The wedge is an open construction ERP that handles multi-currency BOQs and reliable BIM ingestion, the workflow proprietary suites lock behind enterprise pricing.

Overall

Problem Statement

An estimator builds a bill of quantities for a project spanning multiple currencies, but the ERP forces a single currency per budget, and when they upload an IFC model it succeeds at the HTTP layer then fails in background processing with zero elements, so the quantities never populate. They cannot trust the tool for the multi-currency, BIM-driven estimating their projects require, and fall back to spreadsheets or costly proprietary software.

The Idea

An open construction ERP that supports multi-currency bills of quantities and reliable IFC and BIM imports for international contractors priced out of proprietary estimating suites.

Why Now

BIM-based estimating and cross-border construction grew through 2026, and contractors want alternatives to expensive proprietary suites, but OpenConstructionERP's issues show open options stumble on multi-currency budgets and silent IFC import failures, exactly the steps that make or break estimating on international projects.

Target User

Construction estimators and contractors running BIM-based, often multi-currency projects

Target Market

Construction estimating and ERP software

MVP Scope

IFC and CAD import with verified, non-zero element processing.
Multi-currency budgets within a single project.
BOQ generation and rate editing.
Priced BOQ export for tenders.
No full accounting or payroll modules at MVP.

Validation Plan

1Import 200 real IFC models and confirm zero silent zero-element failures.
2Validate multi-currency budgets against manual estimator calculations.
3Onboard 15 estimating firms or contractors in two quarters.
4Track BOQs produced end-to-end from BIM per active user.
5Interview 15 estimators on what their current tools get wrong on international projects.

Product Workflow

1User uploads IFC or CAD models that import with verified element counts.
2The ERP generates a bill of quantities from the model.
3Budgets support multiple currencies with a defined base and conversions.
4Estimators adjust rates and resources per line item.
5Reports export priced BOQs for tendering.

Monetization

Open-source core with a paid hosted option and a pro tier for multi-currency, advanced BIM workflows, and support, billed per project or per seat. The value metric is BOQs produced from BIM across currencies; the buyer is the contractor or estimating firm that wants proprietary-grade estimating without proprietary pricing and will pay for reliable BIM import and multi-currency budgets.

Strategic Upside

An open ERP that nails BIM-to-BOQ across currencies can expand into procurement and project controls for mid-market contractors underserved by enterprise suites; reliable import and multi-currency are the moat, because an estimating tool that drops model elements or forces one currency is unusable on the international projects that most need it.

Acquisition Channels

•Construction-tech and BIM communities and forums.
•AEC and estimating LinkedIn groups.
•Content on open BIM and IFC-based estimating.
•Partnerships with BIM consultancies.
•Industry conferences and quantity-surveying associations.

Competitors

Risks

Procore and established suites have deep features and industry lock-in.
IFC and BIM formats are complex and varied, making reliable import a long build.
Construction software sales cycles are slow and relationship-driven.
Estimators are conservative and slow to switch core tools.
Open-source adoption may not convert to paid in a traditional industry.

Counter Evidence

Many estimators still trust spreadsheets and proprietary tools and resist new ERPs.
Procore and CostX cover deep workflows that an open tool will take years to match.
IFC import reliability is hard enough that even mature tools struggle with it.
