InvoiceProof by SwarmSync

AI invoice review
your finance team can prove.

Run a basic invoice field check and receive a unique proof ID with SHA-256 chain hash metadata before payment releases. Missing POs, duplicate flags, field-presence checks — surfaced with a retrievable verification record. No competitor produces a Proof ID. Not AppZen. Not Stampli. Not Tipalti.

The problem

Finance is asked to move faster — without losing accuracy.

Invoice review is still manual, repetitive, and easy to miss. The wrong miss costs more than the time saved.

Today

Eyes on every line, every week.

AP teams scan vendor names, totals, terms, and bank details by hand. Volume grows. Tooling stays the same. One missed bank change can mean a six-figure write-off.

The gap AI hasn't closed

Extraction isn't review.

OCR and LLMs pull invoice data well. They don't show finance why a result is safe to act on. Controllers need a trail, not just an answer.

AI can extract invoice data. Finance teams still need proof before trusting the result.
How it works

Five steps from invoice details to a proof-backed review.

Enter invoice fields, optional evidence, and rules. Get back a risk result with a retrievable proof record.

01

Submit invoice details

Enter one invoice directly in the self-serve demo. CSV/ERP batch review is a managed pilot.

02

AI extracts the details

Vendor, amount, terms, PO number, line items, bank details, tax IDs.

03

SwarmSync checks for proof

Up to ten checks run; vendor master and history comparisons require submitted evidence or a managed pilot data feed.

04

Risk flags + proof trail

Each invoice gets a risk level, flagged issues, and a hash-linked reasoning trail.

05

Review, approve, or escalate

Finance teams can use the result to make the call; action logging is available in managed pilots.

What InvoiceProof checks

Up to ten verification checks per invoice.

Each check produces a pass, warning, or flag based on submitted fields and available evidence.

Duplicate invoice risk

Match against submitted invoice history by vendor, amount, and reference.

Vendor name mismatch

Compare against submitted vendor-master evidence with fuzzy matching.

Invoice amount mismatch

Header total reconciled against the sum of line items.

Tax + fee inconsistencies

Tax rate vs jurisdiction, fee buckets, expected rounding.

Payment term changes

Net 30 to Net 15 changes are flagged when prior terms are supplied.

Missing PO or approval

Required PO references checked against supplied approval evidence.

Bank detail changes

Routing or account changes are flagged when prior payment details are supplied.

Suspicious vendor changes

New email domain, new entity name, new payee — all surfaced.

Line item math errors

Qty × unit price, discounts, subtotal vs total — recomputed line by line.

Prior invoice comparison

This invoice vs the vendor's last 6: unit prices, cadence, line drift.

BEC protection and vendor-master reconciliation require enterprise data feed integration. Not available in self-serve demo.
