Victor

Invoice error shield

WIP

Every supplier invoice has hidden errors. Victor finds them before you pay.

Work in progress

Victor is being prepared for public launch. The page shows the intended audit flow so finance teams can see how the product is shaping up.

Stop discovering invoice errors in next month's reconciliation. Victor audits each supplier invoice on the spot - line-item math, duplicate-against-prior-periods, off-contract charges, missing required fields, and price drift against the contract you uploaded. Drop one invoice, see every error in plain English.

Flags off-contract charges and missing required fields

What can it do?

Line-by-line math check

Quantity times unit price, subtotal, tax, total - every line is verified. Math errors do not slip through to your AP system.

Duplicate invoice detection

Victor compares each invoice against the prior period and flags repeat invoice numbers, repeat amounts on the same supplier, and same-day duplicates.

Contract-aware price audit

Upload the supplier contract once. Victor checks every line against the agreed price and flags any drift with the exact contract clause.

Off-contract charge detection

Lines or fees that are not on the contract are surfaced separately, so you can decide whether to query them before approval.

Required-field validation

Missing VAT number, missing invoice number, wrong date format, missing supplier reference - flagged before they break your downstream accounting.

Plain-language exception report

Each error is described in terms of what is wrong, what it costs you, and what to do next. No accounting jargon needed to triage it.
