Head-to-Head Comparison
SITE SAMURAI VS PROCORE FOR UK CONTRACTORS
The problem: Procore is a mature US-originated enterprise platform priced and implemented for large main contractors with annual turnover-based contracts and dedicated rollout teams. UK SMEs who buy it typically inherit a bill and a project plan that do not match their operating model. The fix: pick based on operating scale. Site Samurai is UK SME-first with NEC/JCT native applications for payment, HMRC CIS verification, CDM 2015 RAMS, transparent £99/£199/£699 pricing, and unlimited users on every plan. Procore is the right answer at Tier-1 main contractor scale. Site Samurai is the right answer for everyone else.
TL;DR
If you are a Tier-1 UK main contractor with dedicated IT, a multi-region project portfolio, and an annual turnover measured in hundreds of millions, Procore is a credible platform — it is built for enterprise main contractors with dedicated rollout teams and annual turnover-based contracts. If you are a UK SME contractor (£5m-£200m turnover) running projects under NEC4 or JCT 2016 with applications for payment, CIS deductions, RAMS, and CDM 2015 obligations, Site Samurai is the direct answer. Unlimited users on every plan, £99 Starter / £199 Professional / £699 Enterprise per month, 14-day free trial with no credit card required. Procore does not publish UK pricing; it is priced by annual construction turnover and quoted per customer.
Last reviewed: 21 April 2026 (2026). Competitor feature claims verified against procore.com/en-gb on 21 April 2026; Procore pricing is quote-only and scales with annual construction turnover. Competitor source.
Where Procore is strong
- • Mature enterprise-grade platform with deep main contractor workflow (drawings, submittals, RFIs, bid management).
- • Unlimited users on every Procore contract — the commercial model is annual construction turnover, not per-seat.
- • Large third-party marketplace and ecosystem integrations for enterprise IT stacks.
- • Dedicated implementation, professional services, and customer success teams for large rollouts.
- • Global scale across multiple regions, currencies, and languages.
- • Segmented products for main contractors, owners, and subcontractors.
Where Site Samurai is stronger
- • UK-first: Construction Act 1996 s.111 pay less notices, HMRC CIS verification, CDM 2015 Construction Phase Plans natively built in.
- • Transparent, public pricing: £99 / £199 / £699 per month — no annual turnover disclosure required for a quote.
- • Unlimited users on every plan, same as Procore — but at a fraction of the cost for UK SMEs.
- • 14-day free trial with no credit card; live pilot in days, not a multi-month implementation programme.
- • Native CIS with 0%/20%/30% HMRC-returned rates, re-verification cascading forward to unpaid amounts.
- • Two-way Xero and Sage sync (Professional) matches the accounting stack UK SMEs actually use.
- • Integrated commercial controls (POs, GRNs, three-way matching, subcontract tenders, bid levelling) in a single platform.

Depends on your operating model
Enterprise platforms assume enterprise IT, implementation teams, and change programmes. SME platforms assume a QS, a PM, and a director rolling it out themselves.
Best fit by contractor profile
UK SME contractor, 10-300 staff, £5m-£200m turnover, project-based delivery
Best fit: Site Samurai

Tier-1 main contractor, multi-region, £500m+ turnover, dedicated IT and rollout teams
Best fit: Competitor
Procore's enterprise depth (BIM, drawings, submittals, multi-region governance) justifies its implementation effort at this scale.
Mid-market UK subcontractor prioritising AfP, CIS, and cashflow control
Best fit: Site Samurai
Site Samurai's AfP workflow with s.111 pay less notices, HMRC CIS verification, and retention tracker addresses the precise daily cashflow risk.

Where UK SME workflow diverges from Procore's enterprise defaults
Procore was built around the main contractor operating model in the US market and extended globally. The UK adds specific statutory obligations that an SME subcontractor cannot treat as an integration project. Applications for payment sit under the Housing Grants, Construction and Regeneration Act 1996 (the Construction Act) as amended by LDEDCA 2009 — the pay less notice must be served at least 7 days before the final date for payment under s.111 or the notified sum is payable. CIS sits under Finance Act 2004 Chapter 3 — HMRC returns 0% Gross Payment Status, 20% verified net, or 30% unmatched, and the rate must apply per payment. CDM 2015 requires a Construction Phase Plan from the principal contractor. Site Samurai builds these as first-class UK workflows. Procore can be configured to handle them at enterprise scale, but not out of the box for a UK SME.
Choose Procore if
You are a Tier-1 UK main contractor delivering a multi-region £500m+ portfolio programme.
Procore's enterprise breadth (drawings, BIM, submittals, multi-region governance, integrations marketplace) is genuinely stronger at this scale and you have the IT team to implement it.
You need deep BIM/drawings coordination with architects and large design teams.
Procore has first-class drawings management, BIM viewer, submittals, and RFIs. Site Samurai does not compete here.
You operate across multiple countries with multi-currency, multi-language governance.

You are a UK SME contractor (£5m-£200m turnover) under NEC4, JCT 2016, or bespoke subcontracts.
