Site Samurai is construction management software for UK contractors and construction teams that need purchase-order control alongside wider project operations. Its workflow covers purchase-order creation with line items, categories, cost codes, VAT treatment, project-versus-overhead classification, supplier emailing, delivery tracking, goods-received notes, and three-way matching with supplier invoices. The product also includes supplier management, commercial management, safety workflows, fleet tools, and programme management, making it a broader construction platform rather than a purchase-order tool alone.

Pricing is structured around three monthly plans. Starter costs £99 per month and includes unlimited users, unlimited projects, clients and contacts, applications for payment, project and supplier management, and 25 GB of document storage. Professional costs £199 per month and adds purchase orders, goods-received notes, supplier and sales invoices, estimating and BOQ, RAMS, toolbox talks, incidents, resource planning, programme management, Xero and Sage Business Cloud integration, and API access. Enterprise costs £699 per month and adds voice-first site capture, daily AI briefing emails, photo geotag timelines, a 48-hour weather risk board, SSO/SAML, and advanced audit logs. A 14-day trial is available.

The strongest fit is a construction team that wants approvals, approval limits, committed-cost visibility, delivery tracking, and invoice matching connected to project administration. Xero and Sage Business Cloud support accounting workflows, while Microsoft Project XML, DVLA vehicle lookup, LazyQs, and the Progress Photo Sync partner API extend the platform’s construction ecosystem. The purchase-order feature set is concentrated in Professional and above, so Starter suits teams seeking broader project administration without those controls. Teams that need advanced identity and audit capabilities must choose Enterprise, while smaller businesses wanting only basic purchase orders may find the wider construction-management scope unnecessary.
