ONSO

ONSO is a procurement and project cost control platform built specifically for the construction industry.

We exist to fix a problem most teams live with every day: disconnected processes between site, office, suppliers and finance.

Too often, site teams struggle to get materials when they need them, project managers lack real time cost visibility, suppliers receive unclear orders and accounts teams are left untangling errors at the end. ONSO brings everyone into one simple, connected workflow.

From purchase order requests and supplier management to invoice matching, spend analytics and accounting integrations, ONSO gives businesses full real time visibility and control over what’s being bought, when and at what cost.

Our platform is designed to work for every user in the supply chain:

Site operatives raising requests

Project managers controlling budgets

Suppliers responding to quotes and orders

Accounts teams managing invoices and audit trails

No spreadsheets. No chasing. No surprises.

Just clear, controlled procurement that keeps projects moving and margins protected.

ONSO is modern construction procurement that is built around real workflows, not workarounds.
