Every invoice that arrives — fetched from a supplier portal, forwarded by email, or uploaded by hand — is read automatically and run through Etainabl's validation engine before anyone has to look at it.
AI-powered capture
There are no per-supplier templates to maintain. Etainabl uses LLM-powered extraction to read any invoice format — single- or multi-meter, credit notes, awkward scanned PDFs — and pull out every rate, read and charge. Invoices are even retrieved for you automatically from 20+ UK energy and water supplier portals.
40+ validation rules, per meter
Each invoice is checked against 40+ configurable rules, applied to every meter on the bill:
- Contract rates — every unit rate, standing charge and capacity charge matched to your contract, within tolerance
- VAT & CCL — correct VAT rate and reduced-rate de minimis, and CCL checked against HMRC published rates and your chargeable percentage
- Consumption — billed usage cross-checked against half-hourly settlement data, meter reads and previous periods
- Reads — read continuity across consecutive bills, with estimated reads flagged
- Gas conversion — kWh recalculated from reads, calorific value and correction factor
- Duplicates — caught by invoice number and by overlapping billing period
- Account match — every MPAN, MPRN or SPID matched to the right meter
- Passthrough charges — DUoS, TNUoS, BSUoS and other regulated charges surfaced for visibility
Every rule is configurable per company — switch checks on or off, set them to warn or fail, and tune the tolerances to suit your portfolio.
A clear validation queue
Results land in a validation queue marked passed, warning or failed, each with the evidence behind the verdict and a full history of any edits. Invoices you trust can be auto-validated straight through, so your team only spends time on the bills that genuinely need a human eye.
