The Platform Decision
Choosing a commercial intelligence platform is one of the most consequential technology decisions a UK construction firm will make. The wrong choice can lock you into years of inadequate capability. The right choice can transform your commercial function within months.
This article provides an objective comparison of the leading options available to UK construction firms in 2025. We include DealGuard in this comparison because we believe informed buyers make better decisions, and we are confident in how DealGuard performs against the alternatives.
The Contenders
Asite
Asite is a UK-based platform with a strong heritage in construction document management and common data environments. Their commercial module has grown from document control origins to include contract administration and basic analytics.
SAP S/4HANA (with Construction Module)
SAP is the enterprise standard for ERP across many sectors. Their construction module provides project accounting, procurement, and contract administration within the broader S/4HANA ecosystem.
Custom AI Build
Several UK Tier 1 contractors have explored building bespoke commercial intelligence platforms using in-house development teams or systems integrators.
DealGuard (APPIT Software Solutions)
Purpose-built commercial intelligence platform for construction and infrastructure, combining AI clause scoring, scenario simulation, and portfolio analytics.

Pricing Comparison (Indicative, GBP)
Pricing varies significantly based on company size, number of users, and contract volume. The following estimates are for a mid-tier UK contractor (£300-500 million turnover, 150 users, 40-60 live contracts).
| Cost Component | Asite | SAP S/4HANA | Custom Build | DealGuard |
|---|---|---|---|---|
| Annual licence/subscription | £120,000-£180,000 | £350,000-£500,000 | N/A | £380,000-£520,000 |
| Implementation | £80,000-£150,000 | £800,000-£2,000,000 | £1,500,000-£4,000,000 | £250,000-£400,000 |
| Annual maintenance | Included | £70,000-£100,000 | £300,000-£600,000 | Included |
| Training | £15,000-£30,000 | £50,000-£100,000 | £40,000-£80,000 | £30,000-£60,000 |
| **Year 1 Total** | **£215,000-£360,000** | **£1,270,000-£2,700,000** | **£1,840,000-£4,680,000** | **£660,000-£980,000** |
| **Annual ongoing** | **£135,000-£210,000** | **£420,000-£600,000** | **£300,000-£600,000** | **£410,000-£580,000** |
Note: SAP costs assume S/4HANA is already deployed for ERP. If a new SAP implementation is required, add £2-5 million.

## Best-Fit by Company Size and Need
Small Contractors (Turnover < £100 million)
Recommended: Asite or DealGuard Essentials
Smaller firms typically need document management, basic contract administration, and simple analytics. Asite provides good value at this level. DealGuard's Essentials tier offers clause scoring and basic portfolio analytics at a comparable price point, making it the better choice if commercial intelligence rather than document management is the priority.
Mid-Tier Contractors (Turnover £100-500 million)
Recommended: DealGuard
This is where DealGuard delivers its strongest value proposition. Mid-tier firms have sufficient contract complexity and portfolio size to benefit from AI clause scoring and scenario simulation, but lack the budget and IT resources for SAP or custom build. The 6-8 week implementation timeline means value is delivered within a single financial quarter.
Tier 1 Contractors (Turnover > £500 million)
Recommended: DealGuard Enterprise or DealGuard alongside SAP
Tier 1 firms often have SAP already deployed for ERP. DealGuard complements SAP by adding the commercial intelligence capabilities that SAP lacks. Firms like Balfour Beatty, Kier Group, and Costain benefit from DealGuard's AI clause scoring and scenario simulation operating on data from their existing SAP environment.

The Custom Build Question
The appeal of a bespoke platform is understandable. You get exactly what you want, tailored to your processes, with no compromises. The reality, however, is well documented.
Infrastructure and Projects Authority analysis of bespoke technology projects in UK construction shows:
- Average time to deployment: 28 months (vs planned 14 months)
- Average cost overrun: 220% of original budget
- Failure rate: 35% of projects abandoned before completion
- Maintenance burden: Typically requires 4-6 dedicated developers for ongoing support
The fundamental problem is that building AI-powered commercial intelligence requires deep expertise in both AI/ML engineering and UK construction contracts. Firms that attempt custom builds typically have one or the other, rarely both.
McKinsey's guidance on build-vs-buy decisions in construction technology recommends buying platforms for capabilities that are not competitive differentiators and building only where unique processes create genuine advantage.
When Custom Build Makes Sense
Custom build may be appropriate when:
- Your commercial processes are genuinely unique (not just different)
- You have an established, stable AI/ML engineering team
- You are willing to invest £3-5 million over 3 years
- You accept the risk of the platform never reaching production maturity
For most UK contractors, these conditions do not apply.
Integration Considerations
Asite
- Strong integration with other Asite products (common data environment, field management)
- Limited API for third-party integration
- UK-hosted infrastructure
SAP S/4HANA
- Excellent integration within the SAP ecosystem
- Strong API and middleware options (SAP BTP)
- Can be UK-hosted but typically cloud-based
- Requires SAP expertise for integration work
DealGuard
- Purpose-built connectors for UK construction systems (Coins, CEMAR, Asite, Viewpoint)
- REST API for custom integration
- UK-hosted, ISO 27001-certified infrastructure
- Open Banking integration for UK banking platforms
- Integration typically completed by APPIT team within 6-8 weeks
