Stop paying the wrong invoice. Prove the right one.
Invoice fraud, business email compromise, and altered payment instructions cost finance teams real money. Often six figures in a single wire. Invoance anchors every invoice, contract, and payment instruction the moment it's issued, so you have a tamper-proof, cryptographically signed record of what was actually sent. Your vendors verify authenticity from a public link before they pay or change banking details. No software install. No phone call.
The fraud problem
Most invoice and payment fraud doesn't happen because someone broke into your systems. It happens because there's no reliable way to prove which version of a document is real, when it was issued, or that nothing was changed between sender and recipient. Email and PDF were never built to answer those questions.
A vendor (or what looks like a vendor) emails new wire instructions a week before payment is due. By the time someone calls to verify, the wire is already gone and the real vendor never sent the email.
You receive a vendor invoice, route it for approval, and pay it. Months later it surfaces that the routing number was changed somewhere between issuance and approval. The version you paid is not the version the vendor sent.
A new vendor is onboarded with documents that look real but came from a domain one character off from the legitimate one. The first invoice clears. The second one drains a quarter of working capital.
A vendor swears they sent invoice X for amount Y on date Z. You have invoice X for a different amount. With no proof of which version came first or what either party actually issued, the dispute drags on for weeks and erodes the relationship.
How it works
Three steps. No new accounting platform to migrate to. No cryptography knowledge required on your side or your vendor's.
Drop the invoice, contract, or payment instruction into Invoance, either through the dashboard or your accounting tool. We create a tamper-proof fingerprint of the exact file at the moment it was issued, cryptographically signed under your organization's identity. The original is sealed. Any later change to a single character produces a different fingerprint.
Every anchored document gets a public verification link. Send it alongside the invoice, or attach it to your vendor portal. Your vendor, their AP team, or your auditor can open it without an Invoance account.
The recipient downloads the document straight from the verification page. The page confirms the file matches the original: same content, same issuer, same issue date. If anyone tampered with the version they received elsewhere, it won't match. They know before they pay.
What finance teams anchor
Anywhere a document or payment instruction needs to be the same on both sides of the transaction, and provably the original months or years later.
Anchor every outbound and inbound invoice. The recipient confirms they have the version you actually sent before they queue payment, or before you cut a check.
Master service agreements, NDAs, and statements of work anchored at signing. Six months later, any dispute about scope or rates is settled by pointing to the verifiable original.
Wire instructions and ACH details anchored at the moment they're issued. Any later "updated banking info" message is checked against the verifiable original before a single dollar moves.
Anchored POs prove what was ordered, at what price, on what date. Vendor invoices that don't match the original PO get caught before approval, not after payment.
Year-end audit asks for proof of an approval chain or a vendor agreement. Hand the auditor a verification link instead of digging through email. They confirm authenticity on their own.
If a fraud incident does occur, your insurer wants proof of which document was authentic and which was altered. Anchored originals are exactly the kind of evidence claims adjusters can verify without taking your word for it.
Why finance teams use Invoance
Controllers, AP directors, and CFOs don't need another dashboard. They need a way to prove which document is the real one. To vendors, to auditors, to insurers, and to themselves.
When vendors verify the document they received against the anchored original, swapped banking details and altered amounts surface immediately, before a check is cut or a wire is approved. The proof step is the control.
When two parties disagree about what an invoice or contract said, the verification link ends the argument. Both sides see the same provable original. No back-and-forth, no relationship damage, no legal escalation.
External auditors and reviewers don't have to take your word that a document existed on a given date. The verification link does it for them, on their own machine. Less time pulling records, fewer audit findings.
Cyber and crime insurers ask for forensic-grade evidence after a fraud incident. Anchored documents are admissible, independently verifiable proof of which version was original. That's exactly what claims adjusters and forensic investigators look for.
Anchored records cannot be altered, backdated, or deleted after the fact. Not by your team, not by a vendor, not by us. The integrity is enforced by how the system is built, not by whose access you trust.
No replacement of QuickBooks, NetSuite, Bill.com, or your contract tools. Anchor existing PDFs and documents alongside your current workflow. The verification link becomes one extra line in your invoice email.
Common questions
The questions every controller, AP director, and CFO asks before the second meeting.
Does Invoance replace Bill.com or QuickBooks?
No. Invoance complements your existing AP and accounting tools. Keep using Bill.com, QuickBooks, NetSuite, Ramp, or whatever runs your invoicing today. Invoance sits alongside them and produces a tamper-proof anchor for any document you want provable. Most teams paste the verification link straight into the invoice email or vendor portal entry.
How do my vendors verify the document if they don't have an Invoance account?
They don't need one. Every anchored document gets a public verification link. Your vendor opens it in any browser, downloads the file straight from the verification page, and the page confirms the file matches the original. No signup, no install, nothing for them to learn.
What if we get audited and the auditor doesn't know what Invoance is?
Verification doesn't require the auditor to trust Invoance, or even know we exist. Every anchored record carries a cryptographic proof (a signed hash) that can be verified offline against your organization's public key. The verification page documents the process in plain language, and the auditor can validate it independently using standard cryptographic tools.
Is an anchored document admissible as evidence in a dispute or legal proceeding?
The cryptographic proof mathematically demonstrates a file existed in this exact form, signed under your organization's identity, on a specific date. Whether that meets the evidentiary standard for a particular court, regulator, or insurance carrier is a question for your counsel, not us. Most clients use it as forensic-grade evidence to support a case rather than as the case itself.
Verify the original. Pay with confidence.
One altered payment instruction can cost more than a year of Invoance. Talk to us about anchoring the documents your finance team already moves every week, and giving your vendors a way to verify them before they ever wire a dollar.
