Got a chargeback?
Build your first evidence packet free.

Case strength
Strong case. Submit the packet with every exhibit.
Evidence checklist
- Carrier tracking delivered to full order address
- Signature or photo at delivery
- Ship-to matches billing address
- Customer communication
- Order receipt or invoice
Response to the claim
The cardholder states the order was not received. Carrier records (Exhibit A) show delivery on Mar 14 to 118 Alder St, Portland OR, with signature. The address matches the billing address on the card (Exhibit B).
Exhibits
- A UPS tracking 1Z…884, delivered, signed
- B AVS match: billing = shipping
- C Order confirmation email
What is this?
A tool that helps you fight one chargeback at a time, properly.
What does it do?
Checks the evidence you have against what your reason code needs, then builds the packet you upload.
What does it cost to try?
Your first dispute is free. After that, $29 per dispute, one time.
Will it submit anything automatically?
No. You review everything and upload it yourself.
Do you take a cut if I win?
No. Not a percentage, not a fee on wins. Ever.
Does it support my processor?
Shopify Payments, Stripe, PayPal, Square, WooPayments and Braintree, for Visa, Mastercard, Amex and Discover codes.
Evidence audit first
Know what is missing before you use your one chance to respond.
You get one submission and 7 to 21 days. Most disputes are lost because the packet is missing the one thing the issuer looks for on that reason code. WinPacket checks your case against those requirements first, then writes.
- Evidence checklist built from the rules for your exact reason code (Visa, Mastercard, Amex, Discover, PayPal)
- Strength score that moves as you add tracking, emails, policies and logs
- Missing evidence ranked by impact, with how to get each item
- Deadline tracking across every processor, with outcome history
Then the packet, built from the audit

How it works
From dispute notice to upload-ready packet in about ten minutes.
- 1
Enter the dispute
Processor, reason code, amount and the order basics. The form asks only for what wins this code.
- 2
Add what you have
Tracking, emails, listing screenshots, policy, usage logs. Paste text or upload files. See the strength score move.
- 3
Review the packet
Read the summary, the answer to the claim and the exhibit index. Edit anything. Nothing is sent by WinPacket.
- 4
Upload and track
Download the PDF or copy the Stripe fields, submit in your processor, then record the outcome.
Why merchants lose
A lost dispute costs the order, the goods and a $15 fee. Most are lost on paperwork, not facts.
The window is short and you get one shot
Square gives 7 days, PayPal 10, Stripe and Shopify 7 to 21. You cannot amend after submitting.
Processor auto-defense only uses what the processor holds
Not-received, not-as-described and cancelled-subscription cases are won with your emails, policies, usage logs and signed delivery.
Success-fee services take 25% even when you would have won
On a $300 dispute that is $75 to $90 gone. WinPacket is a flat $29 per dispute, and the first one is free.

Questions merchants ask
What exactly do I get for free?+
A complete packet for one dispute: the evidence checklist for your reason code, a strength score, the list of what is missing, a full response letter, an exhibit index, the Stripe field mapping and a PDF. Not a preview, not a sample. Use it to respond to the chargeback you have now.
What happens after the free one?+
Each additional dispute packet is a one-time $29. No subscription, no monthly fee. Regenerating the same dispute after you add evidence is free.
Does WinPacket submit the response for me?+
No. You review and edit the packet, then upload it in your processor's dispute form (Shopify, Stripe, PayPal, Square, WooPayments or Braintree). Nothing is ever sent without you.
Do you take a percentage if I win?+
No. Never. Everything you recover is yours.
Do I need to connect my store or processor?+
No. Paste the order details, tracking and customer emails, upload what you have, and the packet is built from that.
Can I win fraud chargebacks?+
Sometimes. Fraud codes (Visa 10.4, Mastercard 4837, Amex F29, Discover UA02) are won with 3-D Secure, AVS and CVV matches, delivery to the billing address, usage after purchase, or Visa Compelling Evidence 3.0 history. WinPacket tells you honestly when a case is weak so you can accept it and save the countered fee.
What happens to the evidence I upload?+
It stays private to your workspace, is used only to build your packet, is never used to train AI models, and you can delete any dispute or your whole workspace at any time. See the privacy policy for details.
Is this legal advice?+
No. WinPacket organizes facts and evidence according to published card-network and processor guidance. The card issuer makes the final decision on every dispute.
