Site Samurai vs Fieldwire for UK Delivery Teams

Fieldwire is a known option for field task coordination. Site Samurai extends field workflows with UK contractor compliance and commercial execution in one operational stack.

TL;DR

If your dominant need is task management, plan markups, punch lists, and as-built photo capture against a live drawing set — and you already handle applications for payment and CIS in another system — Fieldwire (a Hilti company) is the better fit. It is purpose-built for jobsite task and plan coordination with a strong iOS/Android app. If you need one UK stack covering NEC4/JCT 2016 applications for payment, HMRC CIS verification, RAMS with digital sign-off, CDM 2015 Phase Plans, and subcontractor management alongside field capture, Site Samurai is the better fit. Fieldwire publishes per-user pricing (Basic free, Pro $39, Business $64, Business Plus $89 per user/month billed annually, USD). Site Samurai is £99/£199/£699 flat per month, unlimited users, 14-day free trial, no credit card.

UK-specific regulations this comparison turns on

Fieldwire is a jobsite task and plan coordination product, now part of Hilti Construction Software. Its feature surface is built around US-centric workflows: RFIs, submittals, change orders, lien-style payment claims. UK contractors instead operate under the Construction Act 1996 (HGCRA, as amended by LDEDCA 2009): payment notices due within 5 days of the due date, pay less notices at least 7 days before the final date for payment, and cumulative applications for payment against a valuation schedule. CIS deductions fall under Finance Act 2004 Chapter 3 with HMRC UTR/NI verification. Principal contractors must evidence RAMS and Construction Phase Plans under CDM 2015. None of these are published on Fieldwire's public feature set as of April 2026. Site Samurai builds them natively.

Choose Fieldwire if

Your team works primarily from a live drawing set — markups, punch lists, and as-built photos against the plan are the daily rhythm.

Fieldwire's plan viewer and task-on-plan workflow is a mature, focused product used on 4M+ jobsites.

You already run applications for payment and CIS in another system (e.g. Sage 200 Construction, QuickBooks + CIS add-on).

Fieldwire does not overlap with your commercial stack and can sit cleanly on top of it.

You have a small team (<5 users) and want a genuinely free plan to evaluate jobsite task tooling.

Fieldwire Basic is free for 5 users / 3 projects — a cheaper on-ramp than any paid UK platform.

Choose Site Samurai if

You are a UK subcontractor applying for payment monthly under NEC4 or JCT 2016.

Site Samurai ships Construction Act s.111 pay less notice tracking, cumulative valuations, retention, and a no-login client portal. Fieldwire does not.

You deduct CIS on subcontractor payments and HMRC re-verification matters each run.

Site Samurai verifies UTR/NI with HMRC, applies the returned rate, and cascades re-verification forward to unpaid amounts.

You are a principal contractor producing RAMS and CDM 2015 Construction Phase Plans.

Fieldwire Custom Forms capture certificates but are not a structured RAMS builder with versioning, digital sign-off, and CDM Phase Plans.

Your team is 10+ users and per-seat pricing would push you above £500/month on Pro or Business.

Flat £99/£199/£699 with unlimited users beats per-user pricing once the team crosses ~10-12 paid seats.

FAQ

Frequently Asked Questions

Fieldwire is primarily a field coordination tool focused on task management, plan markups, and issue tracking. It does not include native commercial workflows such as applications for payment, valuations, or retention tracking. Contractors needing commercial control alongside field operations typically require additional software or a more integrated platform like Site Samurai.
Fieldwire provides general field documentation capabilities, but it is not purpose-built for UK-specific compliance obligations such as CDM 2015, RAMS generation, or CIS workflows. UK contractors with compliance-heavy workloads often need to supplement Fieldwire with additional tools or processes.
Fieldwire does not include native CIS or RAMS functionality. These are UK-specific compliance requirements that typically require dedicated tooling. Site Samurai includes CIS and RAMS workflows as core features, integrated directly into project delivery.
Fieldwire's mobile app is well-regarded for field task management and plan viewing. Site Samurai's mobile experience extends beyond field tasks to include compliance documentation, commercial workflows, and subcontractor management, providing a broader operational scope for site-based teams.
Some contractors use Fieldwire for specific field coordination tasks alongside a broader platform. However, running parallel systems increases data fragmentation and admin overhead. Site Samurai is designed as an integrated operational stack that covers field, compliance, and commercial workflows in one place.
