Automated validation caught billing errors that manual checks had missed.
The platform paid for itself from a single billing correction.
Every future invoice is validated automatically, so errors can't slip through.
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.
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.
Each invoice is checked against 40+ configurable rules, applied to every meter on the bill:
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.
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.
