How DuoApp compares to Procore, COINS, Eque2 and the rest.

Most UK construction platforms are either enterprise ERPs that take months to roll out, or finance-first tools the site team never opens. DuoApp is the modern middle ground - one connected system for projects, CIS invoicing, approvals, timesheets and files, on a flat £10 per user, per month. Live in days, not quarters.

// Why contractors choose DuoApp

The same job, with far less friction.

Big ERPs can do almost anything - eventually, expensively, and after a long implementation. DuoApp wins on the things that decide whether software actually gets used on site.

Honest, flat pricing

£10 per user, per month - every feature included. No volume-based fees, no per-module upsell, no "request a quote" wall. You can budget for DuoApp on the back of a fag packet.

Live in days, not quarters

No consultants, no six-month roll-out. Set up your first project, invite your team and subbies, and you're running this week. Enterprise platforms often bill for the privilege of waiting.

Site teams actually use it

A genuine mobile app that works offline, not a desktop system with a thin companion. Subbies raise variations, log issues and submit timesheets from their phone - so your data is real-time.

Built for UK CIS

CIS deductions, retention, applications, split payments and per-role permissions are standard - not a bolt-on. Designed around how UK main contractors and subcontractors actually get paid.

One platform, not five

Projects, invoicing, approvals, files, QA, timesheets and document compliance in one place. No stitching together separate products or paying for integrations that should be standard.

Real UK humans

Built, hosted and supported in the UK from Canterbury. Phone, email and chat with people who understand construction - not an overseas helpdesk running on corporate response targets.

// Head to head

DuoApp vs each platform.

A fair look at where each competitor is strong - and where DuoApp pulls ahead for UK contractors and subcontractors.

DuoApp vs Procore

US · Enterprise PM

Where Procore is strong

  • Huge feature set - drawings, RFIs, submittals and document control at scale
  • Strong for large main contractors running complex, multi-stakeholder programmes
  • Mature ecosystem and large app marketplace

Where DuoApp wins

  • Transparent £10/user pricing vs Procore's custom quotes tied to build volume
  • Native UK CIS, retention and subcontractor payment workflows
  • Live in days without dedicated admins or a long implementation
  • Right-sized for small and growing UK firms, not just enterprise
Bottom line: Procore is a powerful enterprise platform, but its volume-based pricing and implementation overhead are hard to justify for most UK contractors and subcontractors. DuoApp delivers the workflows you'll actually use - at a predictable price, live this week.

DuoApp vs Access COINS

UK · Construction ERP

Where Access COINS is strong

  • Deep, end-to-end ERP - finance, payroll, procurement, plant and HR
  • Widely used by large UK housebuilders and tier-one contractors
  • Robust job costing and CIS for complex finance teams

Where DuoApp wins

  • Onboard in days - independent reviews note COINS can take months and a steep learning curve
  • Simpler, mobile-first experience your site teams adopt without training
  • One flat per-user price instead of enterprise ERP licensing and consultancy
  • Faster ROI for growing contractors who don't need a full ERP
Bottom line: If you're a £100m+ business that needs a full ERP, COINS is built for you. For everyone growing into that, DuoApp gives you the operational and commercial workflows that matter without the implementation project and price tag.

DuoApp vs Eque2

UK · Finance-first

Where Eque2 is strong

  • Deep, native Sage and Microsoft Dynamics integration
  • Strong contract costing, valuations and CVR for finance teams
  • Long UK track record and HMRC compliance pedigree

Where DuoApp wins

  • Built for the site as well as the office - reviewers note Eque2 can create an office/site disconnect
  • Modern, mobile-first screens rather than a finance-led, traditional layout
  • Operational workflows - tasks, QA, snagging and issue reporting - included
  • Flat per-user pricing instead of tiers gated by company turnover
Bottom line: Eque2 shines if your world revolves around Sage and the finance team. DuoApp connects the office and the site in one modern system - so the people doing the work engage with it, not just the accountants.

DuoApp vs Causeway

UK · Commercial suite

Where Causeway is strong

  • Powerful estimating and quantity-surveying tools
  • Strong commercial and supply-chain management for large contractors
  • Established enterprise pedigree across UK infrastructure

Where DuoApp wins

  • One unified platform instead of several separate products to license and join up
  • Far simpler to adopt - no fragmented modules or heavy implementation
  • Stronger on day-to-day workforce, subcontractor and site workflows
  • Predictable per-user pricing with no consultancy lock-in
Bottom line: Causeway is a serious commercial toolkit for large contractors, but it can feel fragmented across products. DuoApp keeps everything in one place and focuses on the workforce and subcontractor workflows that run the job day to day.

DuoApp vs Archdesk

UK · Configurable ERP

Where Archdesk is strong

  • Highly customisable workflows from enquiry to final account
  • Native CIS and Sage integration with strong CVR reporting
  • Good fit for firms with genuinely unique commercial processes

Where DuoApp wins

  • Works out of the box - reviewers note Archdesk's setup is longer because you're "designing" the system
  • Simpler interface and lighter admin overhead
  • Transparent flat pricing instead of premium, quoted licensing
  • Stronger mobile-first site and subcontractor engagement
Bottom line: Archdesk is excellent if you want to engineer a bespoke ERP and have time to configure it. DuoApp gives you proven construction workflows immediately - less to set up, less to maintain, faster to value.
// Also compared

And the rest of the field.

Other platforms UK contractors weigh up - and why DuoApp tends to be the better day-to-day fit.

vs Buildertrend

Buildertrend is popular with US residential builders for client comms and scheduling, but is US-focused with weak UK CIS. DuoApp is built around UK subcontractor and payroll workflows from the ground up.

vs Fieldwire

Fieldwire is strong for plans, punch lists and site coordination, but light on commercial management. DuoApp combines field operations and invoicing, retention, timesheets and approvals in one platform.

vs Trimble Viewpoint

Viewpoint is a capable enterprise platform with strong financial controls, but carries enterprise complexity, cost and a heavy implementation. DuoApp delivers faster ROI at a fraction of the overhead.

vs 4PS Construct

4PS is built on Microsoft Business Central - powerful for larger, Microsoft-centric contractors, with a significant implementation. DuoApp has a much lower barrier to entry and a far simpler setup.

vs StoneRise

StoneRise targets labour gangs, timesheets and CIS payroll well, but with a narrower scope. DuoApp covers the whole picture - projects, plots, QA, workforce, invoicing and materials - end to end.

vs SiteSamurai

SiteSamurai is solid for QA, snagging and site reporting, but limited on commercial controls. DuoApp adds invoicing, labour management, subcontractor management and material ordering alongside QA.

// Best construction software for…

Pick the job, not the brand.

Whatever you searched for, here's where DuoApp fits - and why it's worth a 30-minute look before you commit to anything bigger.

Best for M&E contractors

Variations, applications, CIS invoicing, retention and document compliance - the commercial and operational workflows mechanical & electrical contractors live in, in one app.

Best for subcontractor management

CIS deductions, split payments, retention, per-role permissions and a mobile app subbies actually open. Onboard your supply chain in minutes, not weeks.

Best for housebuilders & developers

Plot-level project tracking, QA and snagging, aftercare and document control - manage multi-plot programmes without an enterprise ERP roll-out.

Best Procore / COINS alternative UK

If a big platform feels like overkill or over-budget, DuoApp gives you the workflows you'll use, on transparent pricing, live in days - not a procurement project.

// Comparison FAQs

Questions buyers ask us.

What is the best construction management software in the UK?
It depends on your size and workflow. For UK contractors and subcontractors who want one connected platform without enterprise complexity, DuoApp offers projects, CIS-ready invoicing, smart approvals, timesheets, file management and a true mobile app on one flat £10 per user, per month - with onboarding in days rather than the weeks or months typical of Procore, Access COINS or Eque2.
Is there a cheaper alternative to Procore in the UK?
Yes. Procore is priced on a custom quote tied to your annual construction volume and aimed at larger contractors, which often makes it expensive for small and mid-sized UK firms. DuoApp is a transparent £10 per user, per month with every feature included, native UK CIS workflows, and no per-project or volume-based fees - a more affordable Procore alternative for UK contractors and subcontractors. See our pricing →
Which construction software is best for subcontractors and CIS?
DuoApp is built around UK subcontractor workflows - CIS deductions, retention, auto-generated applications and invoices, split payments and per-role permissions are included as standard. Unlike finance-first systems such as Eque2 or enterprise ERPs like Access COINS, DuoApp is mobile-first so subcontractors and site teams actually adopt it.
How long does DuoApp take to set up compared to Procore or COINS?
DuoApp customers are typically up and running in days, with no setup fees and no consultants required. Enterprise platforms such as Access COINS, Eque2 EVision, Causeway and Trimble Viewpoint commonly take weeks to months to implement and often require paid consultancy.
Does DuoApp work offline on site?
Yes. DuoApp's mobile app - including quality control and snagging - works offline and syncs when a connection returns, which is essential on UK sites with poor signal. Many desktop-first or finance-led competitors have weaker or no offline support.
Is DuoApp suitable for M&E contractors?
Yes. DuoApp is widely used by UK M&E contractors for project and task management, variations and approvals, CIS-compliant invoicing, retention and deductions, and document compliance - combining commercial and operational workflows that field-only tools like Fieldwire don't cover.
