Why Timely Margin Truth Matters for Practitioners
In energy retail, finance and data teams are tasked withmore than just reconciling numbers — they’re safeguarding the business’s ability to serve real people, not just process loads.
That’s why ENSEK’s approach to gross margin reporting is designed for lives, not loads: delivering audit-ready, point-in-time (PiT) margin truth that empowers practitioners to act with confidence, clarity, and speed. When every decision impacts customers and communities, timely, trusted data is essential.

The Practitioner’s Problem
Energy retail finance is uniquely complex — not due to lack of expertise, but because systems conspire against timely truth. Reconciliation across industry, billing, and sales ledgers is challenging, with each system ‘right’ in its own context but often misaligned when combined. Prior-period corrections (PPCs) and exception economics further complicate the process. Historically, finance teams relied on manual reconciliations and late nights, which could never support leaders who need to act during the period, not after it closes.
ENSEK’s Approach
Design principles
- PiT by design — captures the exact stateat month-end so corrections are attributed to the right meters/accounts andperiods and supports reconstruction of past positions via repeatable runs.
- Full-portfolio reconciliation aligns industry, billing, and sales ledgers that are each “right” in their own context.
- Data products, not reports — curated,finance-grade tables/views built for journals and drillbacks, with calculation elements included in the outputs (and drillbacks) for transparency and auditability.
- Automate the routine; instrument the critical path — routine steps are automated; the critical path is monitored with alerts and telemetry.
- Minimal viable exceptionalism — keep“special cases” to a minimum so flows remain predictable and auditable.
- Neutral external story; detailed internal pack — plain English externally; detailed provenance internally.
- Audit-ready posture — repeatable runs, traceable lineage, and meter-level evidence auditors can replay, with outputs that remain explainable to Finance/Audit.
- Completeness by design — no data is discarded; low-quality instances are cleansed and flagged; quality exceptions are identified for remediation.
Architecture at a glance
- Modern data lakehouse underpinning governed datasets.
- Scheduled, automated workloads that produce PiT snapshots at cut-off.
- Deterministic matching (rule-based, repeatable joins that consistently select the same source, so results are stable and testable).
- Control checks across pipelines and curated finance-grade tables for consumption.
- Supports reconstruction of past positions via repeatable runs and traceable lineage.
Operational Outcomes
- Faster, cleaner close: Finance can post with confidence on day one, with close run as a verification step.
- Explaining prior-period corrections: PiT modelling makes PPCs explicable, attributing effects to the correct meters/accounts and periods.
- Exception economics: The system flags, identifies exceptions as actionable work items, and helps remediate issues that typically drain value.
- Audit posture: Every number is traceable to its inputs, with near-perfect precision and repeatable runs for auditors.
Lessons Learned
- Treat time properly from day zero – retrofitting PiT is costly.
- Decouple reconciliation logic from presentation.
- Standardise exception classes for faster operational loops.
- Make exceptions loud and fixable; alerts shouldbe clear and actionable.
What Good Looks Like
- Governed data products.
- Data engineering for performance at scale.
- PiT data modelling.
- Automated monitoring, alerting, and exception flagging.

FAQ: Common Practitioner Questions
Q: Is the unbilled revenue figure sufficiently substantiated to support journal postings?
A: Yes – it’s calculated from governed data products with drillbacks. Journals are supported by meter-level evidence, and auditors can replay the run at the month-end cut-off with visible calculation components.
Q: What happens when an estimate is replaced by an actual?
A: PiT lets us attribute the delta precisely to the affected meters and periods. The correction flows through revenue and cost with traceable lineage.
Q: Do I need specialist tools to consume this?
A: At present, accessing the detailed gross margin data requires a data lake integration on the customer’s side – a setup common among ENSEK’s customers for sharing large data outputs. ENSEK plans to implement BI tooling during H1 2026 that will allow direct access to the finance reporting and underlying data embedded within Ignition. This will allow users to access data directly without the need for a custom integration.
Note: ENSEK’s Financial Assurance capability is delivered through our Ignition platform and is not available as a standalone product. This ensures seamless data integration, governance, and audit-grade controls.
