Evidence BeforeCommitment.
CleanYield Frontier helps commercial-cleaning contractors turn specifications into evidence-bounded service commitments — connecting workloading, evidence, transferability, confidence and contract learning.
One central question: what service configuration is a contractor actually justified in promising, given the evidence available right now?

Every proposed hours-and-price configuration carries a visible confidence position and an explanation of what would need to be true for that confidence to be justified.
The evidence-bounded chain
About / The Evidence Gap
The hard part is not calculating a number. It is knowing whether the evidence justifies the promise.
CleanYield Frontier is a UK-focused commercial-cleaning service-design, evidence-governance and contract-learning platform. It addresses the evidence gap between a cleaning specification, the workload and price estimate, and the actual service commitment made to a client.
The problem
Contractors need to turn a specification and budget into labour hours, a service configuration, a price and a contractual commitment. Existing workloading tools can calculate these numbers effectively — but the underlying evidence can vary considerably.
- A figure may be based on a generic production-rate benchmark.
- Another may be based on an observation from a real site.
- Another may be based on calibrated historical performance.
- Historical evidence may be reused even when the new site is materially different.
Traditional systems generally do not provide a structured way to show the strength of the evidence behind each material assumption, or to systematically test whether evidence from another site transfers to the new site. Estimating can produce a precise-looking number even when the evidence behind it is weak.
From traditional process to evidence-bounded process
Traditional
Specification → Estimate → Hours → Price → Promise
Evidence-bounded
Specification → Workload → Evidence → Transferability → Confidence → Commitment → Delivery → Reconciliation → Learning
The platform connects these stages into one continuous process. It does not simply generate another number — it makes the evidence behind the number visible and helps determine whether the proposed service commitment is supported by that evidence.
When evidence is insufficient: more evidence, not more guessing.
Workloading & Evidence Capture
Build a workload and cost estimate while capturing the evidence behind material assumptions.
- Smart Workloading & Quote Builder
- Evidence Passport
- Evidence capture
- BICSc/ISSA-style production-rate benchmarks
Confidence, Transferability & Commitment
The core differentiating layer: it evaluates evidence strength, sample depth, transferability, evidence age, context similarity and commitment supportability.
- Evidence Confidence Score
- Transferability Index
- Supported / Conditional / Unsupported classification
Reconciliation & Learning
Once the contract is live, the platform compares the original assumptions with reality.
- Actual labour
- Delivery conditions
- Quality outcomes
- Learning feeds back into the evidence corpus
Workloading → Evidence → Transferability → Commitment → Reality → Learning
Platform
An evidence-governance layer around the numbers you already produce
CleanYield Frontier is built on a layered V5 architecture with a shared Cross-Site Evidence Corpus. It is designed to sit alongside established BICSc/ISSA-style workloading methodology and add evidence governance around it — not to replace existing cleaning-management software.
V5 Architecture
Three layers over one shared evidence corpus
Workloading & Evidence Capture
Produce the workload, labour and cost estimate while recording the evidence behind every material assumption.
- Quote Builder
- Evidence Passport
- E0–E3 grading
- BICSc/ISSA benchmarks
Confidence, Transferability & Commitment
The differentiating layer: it weighs evidence strength, sample depth, transferability and evidence age, then classifies what can be promised.
- Confidence Score
- Transferability Index
- Commitment Classifier
Reconciliation & Learning
Once live, assumptions are compared with actual delivery, and the result upgrades or downgrades the evidence behind them.
- Actual labour
- Delivery conditions
- Quality outcomes
- Corpus feedback
All three layers read from and write to the shared Cross-Site Evidence Corpus, under an evidence decay model.
Ten platform modules
Smart Workloading & Quote Builder
Builds task-level workload, labour, cost and pricing assumptions using task breakdowns, room/area data, frequency and BICSc/ISSA-style production rates as starting benchmarks.
Scenario / Fixed-Budget Planner
Explore different service configurations when budget, available hours or scope change — so trade-offs are understood rather than reduced to one undifferentiated number.
Contract-to-Outcome Structure
Structures the proposed service around scope, assumptions, commitments and expected outcomes, connecting what is priced with what is actually promised.
Evidence Passport
Records the provenance and context of material assumptions, so each important assumption is traceable to its supporting evidence on the Evidence Ladder.
Evidence Confidence Engine
Produces the Evidence Confidence Score (ECS): a 0–100 score combining evidence level, sample depth, transferability and evidence age.
Context Similarity & Transferability Engine
Tests whether evidence from another site can legitimately be applied to a new site across seven structured factors, producing a 0–100 Transferability Index.
Evidence-Supported Service Envelope & Commitment Classifier
Classifies the proposed commitment as Supported, Conditional, or Unsupported / Insufficient Evidence.
Client Trade-Off Output & Evidence Certificate
Presents service trade-offs to the client and generates a client-facing Evidence Certificate — a trust-building commercial artefact.
Bid-to-Mobilisation Reconciliation
Compares original assumptions with actual labour, delivery conditions and quality outcomes. Comparable tracking exists in the market; the differentiation is what the comparison then updates.
Scope Recalculation + Cross-Site Evidence Corpus & Decay Engine
Reconsiders calculations when scope or conditions change, and stores structured evidence from previous contracts under an evidence decay model.
Transferability Index
68/100
Seven structured factors are assessed, and material differences that may prevent evidence from transferring are identified.
Illustrative example.

The long-term Cross-Site Evidence Corpus can become a compounding evidence asset, with confidence declining as evidence ages or important conditions change.
Commitment Classifier
Three outcomes, stated plainly
Evidence provides sufficient support.
The commitment can be made subject to defined conditions or assumptions.
There is not enough evidence to justify the proposed configuration.
Evidence Ladder
Evidence becomes stronger as it is observed, calibrated and validated

Validated / Replicated
Reaching E3 strengthens the evidence position; it is not a guarantee of any particular commercial outcome.
Key innovations
The Evidence Governance Layer
Five mechanisms form the central differentiators of CleanYield Frontier.
Evidence Confidence Score
0–100 confidence score based on evidence level, sample depth, transferability and evidence age.
Context Similarity & Transferability Engine
Structured assessment of whether evidence from one site applies to another.
Evidence Decay Model
Reduces reliance on ageing or contextually outdated evidence.
Client-Facing Evidence Certificate
A clear artefact explaining the evidence supporting a proposed commitment.
Structured Calibration Wizard
Guides contractors through a bounded calibration process when available evidence is insufficient.
Existing market tools already provide
- Production-rate-based bidding
- Workloading
- Quality inspection
- Scheduling
- Labour tracking
- Quoting
Several of these functions are performed well by existing products.
CleanYield Frontier differentiates through
Evidence-strength grading + Transferability testing + Confidence scoring + Commitment classification + Contract-learning
The reviewed competitor set did not show the same combined evidence-governance layer.
How It Works
A continuous loop from specification to learning
Ten connected steps take a contract from specification to a classified, evidence-bounded commitment — and then feed what actually happened back into the evidence corpus.
Start with the Specification
The contractor enters the relevant contract and site requirements.
Build the Workload
Smart Workloading & Quote Builder converts the specification into task-level workload, labour, cost and pricing assumptions.
Capture the Evidence
Material assumptions receive evidence provenance and an Evidence Ladder level (E0–E3).
Test Transferability
Where historical or external evidence is reused, Context Similarity & Transferability evaluates whether it actually applies to the target site.
Calculate Confidence
Evidence Level + Sample Depth + Transferability + Evidence Age combine into the Evidence Confidence Score.
Classify the Commitment
The proposed service configuration is classified as Supported, Conditional or Unsupported.
Present the Client Trade-Off
The configuration and its supporting evidence are communicated through the client-facing output and Evidence Certificate.
Mobilise the Contract
The agreed configuration moves into actual service delivery.
Reconcile Against Reality
Original assumptions are compared against actual labour, delivery conditions and quality outcomes.
Learn and Improve
The resulting evidence feeds the Cross-Site Evidence Corpus, improving the evidence available for future comparable contracts.
Better EvidenceBetter Future Decisions
When evidence is insufficient, the platform makes that visible instead of presenting an unjustifiably confident number. The principle is simple: more evidence, not more guessing.
Target Market
Built for contractors who must justify what they promise
CleanYield Frontier is focused on the UK commercial-cleaning sector, with a clearly bounded primary audience and a deliberately excluded segment.
Primary audience
- UK commercial-cleaning contractors
- Independent and small-to-mid-size contractors
- Competitive multi-site contracts
- Specification-led contracts
Secondary audience
- Larger regional building-services contractors
- National building-services contractors
Outside primary scope
- Single-visit domestic cleaning bookings
- Cleaning marketplaces
These segments are not the target market for the platform.
The platform is designed to sit above established workloading methodology and existing processes, not to replace them.
Bid-versus-actual labour tracking already exists in the market; the differentiation is how reconciliation feeds evidence grading, confidence and transferability.
Where evidence is insufficient, that is made visible rather than presented as an unjustifiably confident number.
Outcomes described across this site are the business outcomes the platform is designed to support, not guarantees of savings or profitability.

Illustrative UK monthly subscription positioning from the business plan; pricing is a starting assumption for commercial validation and may be refined following pilot evidence.
A usage-based add-on is proposed for the Cross-Site Evidence Corpus once opt-in cross-contractor benchmarking becomes available. It would be priced as a small percentage of contract value protected rather than a flat fee. This is future scope, not a currently available feature.

Safer Renewals & Rebids
Transferability helps contractors reuse proven evidence appropriately rather than blindly copying historical figures.
Compounding Evidence Asset
Every reconciled contract can strengthen the evidence corpus for future comparable contracts.
Reduced Disputes
An Evidence Passport creates a documented basis for discussing scope, service and price changes.
Differentiated Positioning
The combined evidence-governance architecture creates a position beyond conventional workloading.
