Head-to-Head Comparison
SITE SAMURAI VS JOBLOGIC FOR UK CONTRACTORS
The problem: contractors running long project schemes often try to stretch a field service platform into project delivery — and lose visibility on applications for payment, CIS deductions, and Construction Act deadlines. The fix: pick the tool built for your operating model. JobLogic is a capable UK field service management platform for mechanical, electrical, and FM service contractors. Site Samurai is a UK project-based construction platform with native NEC/JCT applications for payment, Construction Act s.111 pay less notices, HMRC CIS verification, and RAMS execution.
TL;DR
If you run reactive service and maintenance jobs (M&E, FM, gas, HVAC, planned preventative maintenance) with engineers dispatched to short tickets, JobLogic is the better fit — it is purpose-built for field service management with offline engineer apps, PPM contracts, and job ticketing. If you deliver project-based construction work under NEC4, JCT 2016, or bespoke subcontracts — with applications for payment, Construction Act s.111 pay less notices, CIS deductions at HMRC-verified rates, retention, RAMS sign-off, and subcontractor management — Site Samurai is the better fit. Site Samurai is £99/month Starter, unlimited users, 14-day free trial with no credit card. JobLogic starts from £45/user/month with tier pricing on request. For UK SME contractors building projects rather than running service rounds, Site Samurai is the direct answer.

Depends on your operating model
Field service tools optimise for many short reactive tickets. Project tools optimise for long programmes with valuations, variations, and stage payments. Mis-matched tooling creates re-keying and missed deadlines.
Best fit by contractor profile
UK groundworks or civils subcontractor, 15-100 staff, running projects under NEC4 or JCT
Best fit: Site Samurai
Applications for payment, CIS verification, RAMS, and subcontractor whereabouts are the daily workflow. JobLogic does not cover these.
Mechanical and electrical service contractor with dispatched engineers and PPM contracts
Best fit: Competitor
JobLogic is purpose-built for dispatching engineers to reactive and planned service jobs with offline mobile app and gas certificates.
Regional principal contractor on fit-out, refurbishment, or new-build schemes
Best fit: Site Samurai
Project-based workflows, Construction Act compliance, CDM 2015 Phase Plans, and commercial controls (POs, GRNs, three-way matching) are the right stack.

- • You want every labourer, subbie, QS, and office user on the platform without per-seat costs.
- • You need three-way PO-GRN-invoice matching and committed-cost visibility, not service invoicing.
- • You want unlimited users, transparent £99/£199/£699 pricing, and a 14-day free trial without a credit card.
Choose JobLogic when
- • Your work is reactive service jobs or planned preventative maintenance contracts.

- • Gas certificates and F-Gas compliance are core to your trade.
- • You need an offline iOS/Android engineer app as the primary field workflow.
- • Your revenue is asset-based PPM rather than project-based valuations.
- • Job-by-job and batch invoicing matches your billing model more cleanly than applications for payment.

UK-specific regulations this comparison turns on
UK construction runs on a specific stack of statutes that field service platforms rarely touch. Applications for payment sit under the Housing Grants, Construction and Regeneration Act 1996 (as amended by LDEDCA 2009) — the Construction Act. The Act requires a payment notice within 5 days of the due date and a pay less notice at least 7 days before the final date for payment; miss the window and the notified sum is payable in full. CIS deductions sit under Finance Act 2004 Chapter 3 — the rate HMRC returns (0% Gross Payment Status, 20% verified net, 30% unmatched) must be applied per payment. RAMS live under CDM 2015 alongside the Construction Phase Plan. Site Samurai builds these workflows natively. JobLogic is a field service management tool and does not surface these regulations in its public feature set.
Choose JobLogic if
You run reactive M&E, HVAC, gas, or FM service contracts with dispatched engineers.
JobLogic is purpose-built for this. You need dispatch, route optimisation, gas certificates, and an offline engineer app — not NEC4 early warnings.
Your revenue model is PPM (Planned Preventative Maintenance) contracts against assets.
JobLogic has PPM contracts at Premium. Site Samurai does not model recurring asset servicing schedules.
F-Gas compliance and gas safety certificates are a regulated part of your daily workflow.
JobLogic ships these as first-class modules. Site Samurai does not.
Choose Site Samurai if
You are a UK subcontractor applying for payment every month under NEC4 or JCT 2016.
You need s.111 pay less notice tracking, valuations, retention, and a client portal. JobLogic does not publish an AfP workflow.
You deduct CIS on subcontractor payments and HMRC verification status changes regularly.
Site Samurai verifies UTR/NI with HMRC, applies 0%/20%/30% rates, and cascades re-verification forward to unpaid amounts. JobLogic has no CIS module.
You are a principal contractor producing RAMS and CDM 2015 Construction Phase Plans.
Site Samurai has a structured RAMS builder with versioning and digital sign-off plus CDM Phase Plans.
You want unlimited users so every labourer, subbie, and office user is on the platform.
