Strong dispute evidence answers four questions: what did you buy, what did you pay, what went wrong, and what did you do afterward? Save the order record, listing, payment record, delivery history, messages, and clear photos.
Write the timeline before you file. Then send records that answer the actual claim, rather than every screenshot you have.
Start with the payment route and its deadline. PayPal, a marketplace, and a card issuer each run separate processes. Asking the seller for a refund doesn't automatically preserve every other deadline.

What proof matters in an online purchase dispute
Proof should connect the transaction to the problem. Different disputes need different records.
| Problem | Useful proof | What it should establish |
|---|---|---|
| Item never arrived | Order confirmation, tracking page, delivery address, and carrier messages | The expected delivery date, shipment status, and any address or delivery problem |
| Item differs from the listing | Listing screenshots, order details, product photos, and seller messages | The promised condition or feature compared with what arrived |
| Item arrived damaged | Package label, photos of the box, item photos, and an unboxing video if available | That the package belongs to the order and the damage existed on arrival |
| Refund was promised but not paid | Return approval, postage receipt, tracking, and seller correspondence | That the return or cancellation met the agreed conditions |
| Payment was unauthorized | Account alert, statement, provider correspondence, and fraud report | The transaction details and when you reported it |
An unboxing video can help. It isn't required in every case. Timestamps and metadata support the story, but they don't prove it alone.
Keep the original files, too.
Build your evidence file before filing
Build the file before opening a case, if possible. Listings and message threads can disappear.
- Save the transaction record first. Download the receipt, order confirmation, transaction ID, amount, seller name, and delivery address.
- Preserve the offer. Capture the product page, condition, specifications, photos, promised delivery date, return terms, and seller claims. Include the page address and capture date.
- Keep the full conversation. Save every relevant email or message, including the parts that don't help your position. Export the thread when the service permits it.
- Photograph the item and package. Include the shipping label, packaging, item, serial number, and defect. Use several angles and show scale when that helps.
- Record the remedy process. Keep the return request, seller response, postage receipt, return tracking, and any refund reference.
- Put the dates in order. List the order date, promised delivery date, contact dates, return date, and the result you want.
Name the folder with the platform and order date. Keep an untouched copy of the originals, then redact unrelated personal information only from copies you submit.
PayPal disputes: match the proof to the claim
PayPal's Buyer Protection terms say buyers must open a dispute within the applicable timeframe. If the seller doesn't resolve it, the buyer can move to a claim through the dispute process. PayPal says it makes the final decision under its eligibility rules and the information submitted.
Turns out, the case screen can matter as much as the receipt. Check the deadline shown there and upload evidence that speaks directly to the selected claim type.
Item not received
Show the order confirmation, delivery address, tracking number, carrier status, and seller messages. If tracking says delivered, explain why that scan may not settle the issue, such as a wrong address, suspected misdelivery, or an open carrier investigation.
Use a carrier record or case number when possible. A typed statement alone is weaker.
Significantly not as described
Make the mismatch easy to see. Compare the original listing with photos of the item you received, then identify the exact condition, feature, quantity, or authenticity statement that differs.
The dispute should identify a material difference. Disappointment or buyer's remorse usually doesn't do that.
If you suspect counterfeit goods, describe the objective signs and keep the item until PayPal gives return or inspection instructions. PayPal's terms say that if a seller loses a Significantly Not as Described claim because the item was counterfeit, the seller must provide a full refund and the buyer won't receive the item back.
PayPal isn't a general product warranty. The transaction and claim must still qualify under its current Buyer Protection rules.
Amazon, eBay, Etsy, and Shopify evidence
Marketplace guarantees are internal platform policies, not one shared process. A decision on one site doesn't bind another company.
Amazon
Amazon's published A-to-z Guarantee information says a buyer may need to contact a third-party seller first and meet order-specific timing and eligibility conditions. Country and order type can affect the route, so follow the instructions attached to your U.S. order.
Submit the order page, original listing, seller messages, delivery record, and return tracking. If the seller promises a refund or replacement, save that promise and the later refund status.
eBay
Open the issue from Purchase History before the case window closes. Keep the listing, seller messages, tracking, photos, and proof that any returned item reached the seller.
eBay's Money Back Guarantee policy says a buyer or seller may appeal an eBay decision within 30 calendar days. That is an appeal period, not a universal deadline for opening every case. Use the dates shown in your transaction.
Etsy
Etsy tells buyers to send a Help with order request before opening a case. Its instructions mention a 48-hour wait, along with other order, location, and timing conditions.
Save the listing, personalization instructions, Etsy Messages, photos, shipping records, and any agreement about a replacement. The instructions also say refunds processed by Etsy must take place within 180 days of the transaction. Use Etsy's own message system whenever possible.
Shopify stores
Shopify is often the software behind a store, not the party deciding whether to issue a refund. Thing is, there is no single Shopify buyer-case timetable that replaces the merchant's terms or your payment provider's process.
Contact the store first. If it doesn't respond, use the dispute process for the payment method you used. Include the store's name, order number, refund request, and every response.
When to use a credit card dispute
A credit card chargeback is separate from a PayPal or marketplace claim. The card issuer reviews the transaction under its own billing-dispute process and may request the receipt, listing, correspondence, return tracking, and platform decision.
Call the number on the back of the card. Ask for the filing deadline, required documents, and the correct address or online form for a billing dispute. Keep a copy of everything you submit.
Don't automatically wait for a platform decision. The issuer's deadline may arrive first. If a PayPal or marketplace case is already open, tell the issuer about it.
Avoid duplicate refunds. Don't accept or pursue two refunds for one transaction without disclosing the other case.
Debit cards, prepaid cards, bank transfers, and person-to-person payments can follow different procedures. Report unauthorized payments promptly, and don't assume credit card protections apply to them.
If a bank or card company mishandles your complaint, the Consumer Financial Protection Bureau complaint portal accepts complaints about credit cards, checking accounts, money transfers, and other financial products. The CFPB says companies generally respond in 15 days. You can review that response and provide feedback within 60 days.
A CFPB complaint doesn't replace opening the original payment dispute on time.
Deadlines and mistakes that weaken a case
Every route has a clock. Record the date you opened the case, the seller's response deadline, the return deadline, and any appeal date.
Watch for these problems:
- Using the wrong process. An item-quality complaint is different from an unauthorized-payment report.
- Sending cropped screenshots. Missing dates, usernames, URLs, or surrounding messages can remove important context.
- Returning an item without tracking. Keep the receipt and delivery confirmation.
- Calling a preference a defect. Explain the specific mismatch, damage, or missing feature.
- Relying on a timestamp alone. A timestamp supports authenticity but doesn't prove who caused the damage.
- Missing a response or appeal window. A seller's promise to investigate doesn't necessarily pause the platform clock.
Keep the message factual. State the order number, the problem, the evidence attached, and the remedy requested.
Questions shoppers often ask
Is an unboxing video required?
Usually, no. Clear photos of the packaging and item, along with the listing and messages, may be enough.
A video is supporting evidence. It isn't a guaranteed result.
What if tracking says the package was delivered?
Save the full tracking details and contact the carrier promptly if you suspect a misdelivery. Explain any issue with the delivery address, signature, delivery photo, or carrier investigation.
The platform or issuer decides how much weight to give that evidence.
Can I file with PayPal and my card issuer?
Possibly. PayPal and the card issuer use separate processes.
Check both deadlines and tell each provider about the other case. Avoid receiving two refunds for one transaction.
What if the seller stops responding?
Save the unanswered messages. Then move to the platform or payment provider's formal process before its deadline.
You don't need an endless email exchange to create a record.
Your next move
Open one folder now. Put the order confirmation, listing, payment entry, full messages, tracking, and photos inside it.
To be honest, a tidy file beats a dramatic explanation. Check the controlling deadline, then file through the correct platform or payment route today.
