INTEGRATIONS

A short, honest list of what Site Samurai connects to today.

We would rather list five integrations that actually work than twenty that read well on a landing page. If something you rely on is missing, tell us and we will be straight with you about whether it is on the roadmap.

Accounting

Two-way OAuth connections to the accounting packages UK construction SMEs actually run. Invoices, payments and contacts sync both ways; supplier bills auto-match to purchase orders.

Xero

OAuth connection with two-way sync for invoices, payments and contacts. CIS tax codes are mapped on the way through, and supplier bills auto-match to purchase orders raised in Site Samurai.

Sage Business Cloud

OAuth connection to Sage Business Cloud Accounting for invoice, payment and contact sync. Sage 50 desktop and Sage 200 are not supported — the connector is API-only.

CIS and compliance (in-product)

CIS handling is built into Site Samurai rather than brokered through an HMRC API. You verify subcontractors on the HMRC portal yourself; Site Samurai stores the outcome and applies the right deduction rate from then on.

CIS deductions

Stores 0%, 20% and 30% CIS rates per subcontractor, applies them to bills automatically, keeps timestamped evidence of the rate that was in force, and formats deductions so they export cleanly to Xero or Sage. HMRC verification itself is done by you on the HMRC portal — Site Samurai records the result, it does not call HMRC.

Field and fleet

DVLA vehicle lookup

Free DVLA lookup built into the Fleet module. Enter a registration and Site Samurai returns MOT status, tax status and basic vehicle details. No customer configuration, no separate account — it is part of the product.

Programme and scheduling

Microsoft Project (MSP XML)

Import and export programme files in the Microsoft Project XML format so your programme can move between Site Samurai and MS Project. This is a file format, not a live connector — there is no running link between the two systems.

Partners

LazyQs

AI tender and contract review from our partner LazyQs. Site Samurai customers get a 25% discount, and Enterprise customers get the Professional tier free. Managed from in-app Integrations settings. Available on all plans.

Progress Photo Sync partner API

OAuth partner API that lets approved partner apps — for example Social Post — pull site progress photos with scoped access. Niche, but real. Available to approved partners only; not a general public API.
