The AP workflow normalises supplier identity, invoice number, date, amount, tax and purchase-order evidence, then compares the exact source document with invoices already posted or queued for payment.
Human invoice exception review
Duplicate invoice detection and review before payment
A bounded accounts-payable use case for comparing incoming invoices with prior records, routing exact or near-duplicate candidates to human review, and preventing a second payment without auto-rejecting legitimate invoices.
Best fit
Small finance teams and bookkeeping/accounting service firms receiving recurring PDF invoices.
The operating job
This use case fits AP teams where the same supplier invoice can arrive twice by email, portal, e-invoicing or resubmission, and where both a missed duplicate and a false positive can create real cost.
Focused offer: Extract invoice facts, flag deterministic exceptions and require a reviewer to compare them with the exact source PDF before one explicit decision.
Use-case workflow
How the bounded workflow runs in practice.
The page is intentionally specific to one operating job. It is not a product-name-swapped landing page and does not create new proof beyond the underlying offer.
Exact-key collisions are strong duplicate candidates while near-matches remain review candidates; the workflow preserves both source documents instead of automatically declaring a fuzzy match to be a duplicate.
An accountable reviewer compares the candidate pair with source documents, purchase evidence and payment state, then records duplicate, not duplicate or needs escalation before any payment-control action.
The decision evidence and processed-invoice state are retained so repeated submissions can be recognised later; the workflow supports duplicate prevention but does not authorise payments or promise that every duplicate will be caught.
Boundary
Keep the use case inside the product's evidence boundary.
Clean extraction remains ready_for_review, never automatic approval
No autonomous payment, accounting/tax/legal advice or fraud assurance
Custom extractor templates are trusted operator configuration only
