Bill Validation

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, including single- or multi-meter, credit notes and 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.
