AffixBuild
Construction ERP · Contractor OS

Run the whole job from tender to certificate.

AffixBuild connects nine modules around one priced BOQ — so your tender becomes the budget, the budget tracks the site, and the site generates the bill. No more spreadsheets that drift apart.

The thread

One BOQ runs through everything

Most tools treat estimating, costing and billing as separate apps. AffixBuild keeps a single priced line-item list at the centre — every module reads and writes the same source of truth.

Why AffixBuild

Engineered for how contractors actually work

Not a generic ERP bent into shape — a system that speaks BOQ, cost codes and certificates from the ground up.

  • Multi-tenant from day one

    Every record scoped to your organisation and isolated at the database level. Org-wide and project-level roles for PMs, QSs, site engineers and accountants.

  • Built for the field

    Site progress, attendance and equipment logs capture offline and sync when signal returns. The office sees real numbers, not week-old paper.

  • An auditable money trail

    Tenders, POs, IPCs and wage runs carry immutable history and approvals — with retention, advances and variations handled by the system, not by hand.
