Stop Losing Chargebacks. Start Winning with Forensic-Grade Evidence.
Merchants lose 70-80% of chargebacks because they submit weak evidence — screenshots with no metadata, no timestamp proof, no chain of custody. ProofSnap captures your product pages, checkout flow, and terms with cryptographic hashing and an independently verifiable timestamp — a forensic evidence package that payment processors take seriously.

Why Merchants Lose Chargebacks
Payment processors reject most representments because merchants submit weak evidence. Here's what goes wrong.
Screenshots Are Easily Disputed
Regular screenshots can be edited in seconds. Payment processors know this and give them minimal weight in disputes.
Missing Metadata
Without the URL, IP address, TLS certificate info, and browser data, there's no way to prove the screenshot came from your actual site.
Unreliable Timestamps
File creation dates can be modified. Without an independent, tamper-proof timestamp, you can't prove when the content existed.
No Chain of Custody
Visa CE 3.0 and Mastercard require documented proof that evidence has not been altered. Without chain of custody, representments fail.
How ProofSnap Works for Chargeback Defense
Four steps to build an evidence package that payment processors accept.
Navigate to the Page
Go to your product page, checkout flow, terms of service, or refund policy in Chrome.
Click ProofSnap
ProofSnap captures the full page with metadata, cookies, TLS certificate info, and browser data.
Download Evidence Package
Get a ZIP with screenshot, PDF report, SHA-256 hashes, blockchain timestamp, digital signature, and chain of custody.
Submit to Payment Processor
Attach the evidence package to your Visa CE 3.0 or Mastercard representment for a complete defense.
The complete workflow at a glance.

Common Chargeback Scenarios
ProofSnap helps you build evidence for the most frequent chargeback reason codes.
Item Not as Described
The most common reason code. Customers claim the product differs from what was advertised.
What to capture:
- -Product page with description, photos, and specs
- -Size charts and material specifications
- -Return and refund policy page
- -Terms and conditions at time of purchase
Unauthorized Transaction
Cardholder claims they did not authorize the purchase. Often friendly fraud where the buyer simply wants a refund.
What to capture:
- -Order confirmation page with customer details
- -Shipping tracking page with delivery confirmation
- -Customer account activity and login history
- -Prior transaction history with same customer
Service Not Received
Customer claims the product or service was never delivered, despite your records showing otherwise.
What to capture:
- -Delivery confirmation and tracking page
- -Communication logs with the customer
- -Service access logs or download records
- -Digital product delivery receipts
When to Capture Evidence
Proactive evidence collection beats reactive scrambling. Here's exactly when to use ProofSnap in your e-commerce workflow.
Capture immediately when you:
- Launch or update a product listing
- Change pricing, shipping, or return policies
- Update terms and conditions
- Receive a high-value or suspicious order
- Ship an order (capture tracking page)
Capture weekly as routine:
- Top 10-20 product pages (best sellers)
- Checkout and payment flow
- Refund and return policy page
- FAQ and contact pages
- Size charts and specification pages
Each capture takes 10 seconds. A weekly routine of 20 captures builds a timestamped evidence library in under 4 minutes.
The Math Is Simple
One won chargeback saves you more than a full year of ProofSnap.
Average chargeback costs $315 (transaction + fees + penalties)
ProofSnap Professional costs $8.99-$24.99/month
One won chargeback pays for 6+ months of ProofSnap
Tax Tip
ProofSnap is a deductible business expense for e-commerce merchants — making it effectively free for tax purposes. Consult your tax advisor for details.
Quick Calculation
If you face just 2 chargebacks per year (average for small merchants), winning even one saves you $315 — that pays for nearly 3 years of the Essential plan.
How ProofSnap Fits Your Existing Stack
ProofSnap doesn't replace your chargeback tools. It fills the evidence gap they can't.
| Tool | What it does | What it lacks |
|---|---|---|
| Shopify Protect | Auto-resolves fraud chargebacks | No coverage for "item not as described" disputes |
| Chargeflow / Disputifier | Automates representment letters | Uses your existing data — no forensic web captures |
| Stripe Radar / PayPal | Fraud prevention at checkout | No evidence capture for post-purchase disputes |
| ProofSnap | Captures product pages, terms, checkout with forensic evidence | Fills the evidence gap the others miss |
Use ProofSnap alongside your existing tools. It strengthens their representment data with independently verifiable evidence.

Frequently Asked Questions
Yes. ProofSnap evidence packages include SHA-256 cryptographic hashes, Bitcoin blockchain timestamps (OpenTimestamps), RSA-2048 digital signatures, and a documented chain of custody. This level of forensic integrity exceeds what most payment processors require for representment under Visa Compelling Evidence 3.0 and Mastercard dispute resolution frameworks. The blockchain timestamp provides an independent, tamper-proof record that the captured content existed at a specific point in time.
For Visa Compelling Evidence 3.0, capture your product listing pages (with descriptions, images, prices), checkout flow, terms and conditions, refund/return policy, shipping policy, and any customer-facing disclaimers. For fraud disputes, also capture order confirmation pages, shipping tracking pages, and delivery proof. ProofSnap records all metadata including the URL, timestamp, and TLS certificate — proving the content came from your legitimate domain.
A regular screenshot is just an image file with no proof of authenticity. It can be edited in Photoshop in seconds, and the file timestamp can be changed by modifying system settings. ProofSnap creates a forensic evidence package that includes: (1) SHA-256 hashes of every file for tamper detection, (2) a Bitcoin blockchain timestamp providing an independent proof of when the capture occurred, (3) RSA-2048 digital signature binding all evidence together, (4) full metadata including URL, IP, TLS certificate, cookies, and HTTP headers, (5) complete HTML source code, and (6) a documented chain of custody log.
You can, but proactive capture is far more effective. If you capture your product pages, terms, and checkout flow before a dispute is filed, the blockchain timestamp proves the content existed at the time of the transaction. Captures made after a dispute has been filed still have value — they show your current policies and product descriptions — but the timestamp will show the capture occurred after the dispute date. Best practice: capture your key pages regularly (weekly or after any content change) to build a timestamped evidence library.
Yes. ProofSnap is a Chrome extension that works with any website you can view in your browser. This includes Shopify storefronts, WooCommerce sites, Amazon seller pages, eBay listings, Etsy shops, BigCommerce, Magento, and any other e-commerce platform. It also works with payment processors like Stripe Dashboard, PayPal, and Square — so you can capture transaction records, customer communications, and dispute details from any platform.
Blockchain timestamps are permanent and independently verifiable for as long as the Bitcoin blockchain exists. Unlike server-based timestamps that depend on a company staying in business, ProofSnap uses OpenTimestamps to anchor evidence hashes directly to the Bitcoin blockchain. Anyone can verify the timestamp independently using open-source tools — no need to trust ProofSnap or any third party. The timestamp proves that the evidence existed at a specific point in time and has not been modified since.
