The Problem With Proving Financial Records
Financial fraud often involves retroactive document alteration. Audit trails in accounting software can be overridden. Regulators need proof that records existed before an investigation began.
Creation disputes are won by whoever has the best evidence of timeline, not by who claims loudest.
For accountants, CFOs, auditors, financial advisors, business owners, this is not a theoretical risk — it is a daily reality. An IRS audit questions when a tax filing was prepared. Timestamped copies of the filing prove the document existed before the deadline, not retroactively created.
How TimeProof Solves This
When you timestamp financial records with TimeProof, TimeProof uses client-side file hashing (SHA-256). That 64-character value is the unique fingerprint for the exact version you selected, and if even one byte changes, the hash changes too. Your file never leaves your device.
TimeProof proves file existence by anchoring file hashes to the Polygon blockchain. The blockchain records the hash, timestamp, and transaction ID permanently, so anyone can verify the record independently on Polygonscan without relying on editable metadata or a vendor-controlled database.
For accountants, CFOs, auditors, financial advisors, business owners, that means establishes priority of creation through blockchain-verified timeline evidence. timestamping financial statements, tax filings, and audit reports at the time of creation provides independent proof of when the records were finalized.
Specific to Financial Records
Timestamping financial statements, tax filings, and audit reports at the time of creation provides independent proof of when the records were finalized. Common file formats include PDF, XLSX, CSV, QBO, QFX, OFX, and TimeProof handles all of them. Whether you are using QuickBooks, Xero, SAP, Excel, FreshBooks, the workflow is the same.
The Metadata Problem
Many people assume file metadata is sufficient proof. It is not.
Accounting software audit logs are controlled by the same organization being audited. They are not independent evidence.
A blockchain timestamp is independent of your file’s metadata. It is stored on the public Polygon blockchain, which no one controls. Even if every byte of metadata is stripped, your timestamp remains permanent and verifiable.
Step-by-Step: Proving Your Financial Records
Anchor the original source file before it leaves your control so later ownership arguments refer back to the exact work product you created. Best used before publishing, pitching, licensing, or sharing the original work externally. Common files in this workflow include original masters, source files, and milestone drafts. Typical reviewers or counterparties include clients, platforms, and counsel.
- Save the original source file, master, or milestone draft that represents the work you may later need to claim.
- Timestamp that exact file before it is published, licensed, pitched, or widely shared.
- Keep the certificate and Polygonscan link with the project archive, license log, or ownership file.
- Timestamp later revisions separately so updated versions do not overwrite the original ownership record.
Step 1: Select your file. Open TimeProof and drag your file onto the upload area. TimeProof accepts PDF, XLSX, CSV, QBO, QFX, OFX and every other file format. The SHA-256 hash is computed entirely in your browser — your file never leaves your computer.
Step 2: Choose your timestamp type. Use scheduled timestamps for 1 credit per file, or use verified instant timestamps for 2 credits per file when immediate anchoring matters. Both produce permanent, identical proof.
Step 3: Confirm and anchor. Click the timestamp button. TimeProof computes the SHA-256 hash locally, sends it to the Polygon blockchain smart contract, and returns your proof. You pay zero gas fees — TimeProof covers all blockchain costs.
Step 4: Download your proof. You receive a PDF certificate and a direct link to the blockchain transaction on Polygonscan. Verified instant timestamps add a verified identity badge, and Legal-Grade adds the Courtroom-Ready PDF, JSON metadata, JWS identity attestation, and Complete Evidence ZIP.
Step 5: Add Legal-Grade if needed. Legal-Grade is a verified per-batch upgrade. Starter and Pro charge 50 credits for up to 25 files, then +2 credits per file after 25. Business charges 25 credits for up to 25 files, then +1 credit per file after 25. Enterprise includes Legal-Grade. It adds the Courtroom-Ready PDF, JSON metadata, JWS identity attestation, and Complete Evidence ZIP.
What You Receive
Every TimeProof timestamp for financial records includes:
- PDF certificate - a readable proof document for the exact financial records you timestamped, ready to keep with the project or share when timing becomes disputed.
- Polygonscan link - direct public verification of the on-chain hash, timestamp, and transaction.
Verified instant timestamps also include: 3. Verified identity badge - the certificate shows the timestamp was created by a verified account, which is useful when delivery timing, authorship, or submitter identity may later matter.
With the Legal-Grade upgrade, you also receive the core evidence-package components documented by TimeProof: PDF, JSON, JWS identity attestation, and a ZIP bundle.
- Courtroom-Ready PDF - a presentation-ready evidence certificate for disputes around prove you created or owned it first, payment, originality, or formal review.
- JSON Metadata - machine-readable timestamp data for technical teams, audit trails, or structured evidence review.
- Identity Attestation (JWS) - a signed proof that ties the timestamp to a verified identity and can be verified through /.well-known/jwks.json.
- Complete Evidence ZIP - one bundle containing the Courtroom-Ready PDF, JSON Metadata, Identity Attestation (JWS), and supporting proof materials so counsel, clients, or reviewers can inspect the complete record in one place.
Why Blockchain vs Other Methods
TimeProof uses Polygon because accountants, CFOs, auditors, financial advisors, business owners need proof that is fast to create, inexpensive to repeat, and easy for third parties to verify.
TimeProof proves file existence by anchoring file hashes to the Polygon blockchain. This gives reviewers a public record they can inspect independently on Polygonscan.
- Speed: about 2-second block times when verified instant proof matters.
- Cost: users do not buy crypto or manage gas fees because TimeProof covers blockchain costs.
- Public verification: counterparties, clients, auditors, or counsel can inspect the record independently on Polygonscan.
- Security: the record sits on a public, tamper-resistant network aligned with Ethereum.
- Permanence: the timestamp remains verifiable long after the financial records have been shared, reposted, or challenged.
Real-World Scenario
A creator or team needs to show that the exact source file existed under their control before reposting, derivative use, or a competing ownership claim emerged. The files at issue are often source files, original masters, and milestone drafts. Typical reviewers or counterparties include clients, platforms, and counsel.
An IRS audit questions when a tax filing was prepared. Timestamped copies of the filing prove the document existed before the deadline, not retroactively created.
Another party claims prior creation, republishes the work, or disputes who first held the master file. The timestamp ties the original file hash to a public date before later copies, uploads, or conflicting ownership assertions muddy the timeline.

Pricing
TimeProof uses one unified credit balance, so you can prove financial records as part of normal work instead of waiting for a dispute.
- Scheduled timestamps: 1 credit per file - available to everyone, with proof available within 6 hours.
- Instant timestamps: 2 credits per file - available to verified subscribers, anchored in about 2 seconds.
- Legal-Grade: Starter and Pro: 50 credits up to 25 files, then +2/file. Business: 25 credits up to 25 files, then +1/file. Enterprise: included.
One-time packs start at $15 for 100 credits. Verified monthly plans start at $19/month and include identity verification for instant timestamps and Legal-Grade.
Monthly financial statements use 1 scheduled credit each. A 20-file audit bundle would use 20 credits. Use scheduled timestamps for routine protection, verified instant timestamps when timing must be immediate, and Legal-Grade when the record may be challenged formally.
For financial records, the cost is based on the number of files you anchor, not the file size. Scheduled timestamps use 1 credit per file, while verified instant timestamps use 2 credits per file.
Privacy
Your financial records never leave your computer. TimeProof uses client-side file hashing (SHA-256). Only the 64-character hash string is sent for anchoring. Because SHA-256 is one-way, it is not possible to reconstruct the original file from the hash. That lets accountants, CFOs, auditors, financial advisors, business owners protect client work, unpublished material, and high-value source files without exposing the underlying content.
