If an online order goes wrong, preserve proof that answers four questions: what you bought, who sold it, what you paid, and what happened next. The order confirmation is the anchor. It rarely settles the whole complaint.
Save the listing, payment record, messages, shipping history, and photos before asking for a remedy. This U.S.-focused process can support a merchant complaint, marketplace case, PayPal dispute, or qualifying credit-card billing dispute. Company policies and legal deadlines differ, so the payment route matters.
No receipt? Don't panic. A payment record, seller email, order number, and other matching records can still connect you to the purchase.
What counts as proof of an online purchase?
Strong evidence is specific, dated, and easy for someone else to verify. No single document is always required.
| Record | What it shows | What it may not prove |
|---|---|---|
| Order confirmation or invoice | Seller, item, price, date, order number, and delivery details | Whether the item shipped or arrived in good condition |
| Card, PayPal, or bank record | Payment date, amount, merchant descriptor, and transaction reference | The exact item or promise made by the seller |
| Product listing and checkout page | Description, model, condition, shipping promise, and return terms | What the seller's page said after it was edited |
| Seller messages | Your complaint, the response, and any refund promise | That a verbal promise was actually completed |
| Tracking and return records | Shipment scans, delivery status, return label, and drop-off | That the package reached you personally |
| Photos or video | Wrong item, damage, missing parts, packaging, or visible defects | When the file was created unless its context is clear |
Keep original emails, not just screenshots. Download invoices when possible, and save messages in the platform where the conversation happened.
Capture the seller's promise before it changes
Product pages can be edited, removed, or replaced. Turns out, the listing often matters more than the receipt in a description or quality dispute.
Save:
- The product title, model, size, color, condition, and seller name.
- The listed price, shipping charge, tax, and promised delivery window.
- The product description, photos, warranty language, and return terms.
- The checkout total and the confirmation page.
- The page address and date of the capture.
A screenshot with no order number or date has less context. Keep the full page when possible, and do not crop away the seller identity or key terms.
Build a clean evidence file
Work in order. A reviewer should be able to understand the purchase without guessing.
- Create one folder. Name it with the seller, order number, and purchase date. Keep a private backup.
- Preserve the originals. Save the confirmation email, invoice, platform messages, and downloaded files. Do not edit the original copies.
- Write a short timeline. List the order date, promised delivery date, actual delivery or non-delivery, complaint date, and every response.
- Connect the payment. Add the relevant statement line or transaction page. Redact unrelated account details, but leave the date, amount, merchant descriptor, and reference visible.
- Show the problem clearly. Photograph the outside packaging, shipping label, item, serial number, and defect. For a missing delivery, save tracking scans and the seller's shipping statements.
- Make one written request. State the problem, attach the key records, and ask for one remedy. Keep the tone factual.
- Submit a numbered packet. Use file names such as
01-order-confirmationand02-payment-record. Keep the submission receipt, case number, and date.
A short index helps. It also stops you from sending random files in a hurry.
Write a complaint that asks for a clear remedy
State what happened, what you want, and why the attached records support it. A full refund, replacement, repair, or delivery request is easier to evaluate than a long accusation.
Use this as a starting point:
Subject: Request for [refund, replacement, or delivery] - Order [number]
Hello,
I placed order [number] with [seller] on [date] for [item] at a total price of [amount]. The problem is [item never arrived, item is defective, item is incorrect, or refund is missing].
I contacted you on [dates]. The attached records include the order confirmation, payment record, listing, messages, tracking information, and photos.
Please provide [specific remedy] and confirm the next step by [date]. If a return is required, please provide the return instructions and any required label.
Thank you,
[Name]
Attachments: 01-order-confirmation, 02-payment-record, 03-listing, 04-messages, 05-photos
Send the request through the seller's official contact method and keep proof of submission. Avoid sending original physical documents.
Choose the route that matches the payment
A merchant complaint, a marketplace case, a PayPal dispute, and a card billing dispute are separate processes. Start with the route that actually handled the payment or sale.
| Route | Useful proof | Main limit |
|---|---|---|
| Seller directly | Order records, listing, payment evidence, messages, and photos | The seller's policy and the facts of the transaction control the response |
| Marketplace | Order ID, platform messages, listing, tracking, and condition photos | Current program terms and case deadlines control eligibility |
| PayPal | Transaction ID, listing, seller communication, delivery records, and defect evidence | Only eligible transactions and claim types qualify under PayPal's terms |
| U.S. credit card | Written billing-error notice, statement, order details, and merchant correspondence | The federal billing-error process applies only to qualifying issues |
| Debit card, prepaid card, bank transfer, or payment app | Transfer reference, seller records, and all contact attempts | Protections and deadlines vary by provider and payment type |
A chargeback is not a general dissatisfaction button. Describe the facts accurately, and do not call a purchase unauthorized merely because the item disappointed you.
If you paid by U.S. credit card
Thing is, a bank statement proves that money moved. It usually does not prove which item was promised or why the seller failed.
For a qualifying credit-card billing error, send a written dispute within 60 days after the statement that first showed the error was sent to you. Explain the amount, transaction, problem, and requested correction. Include copies of the order record and your attempt to resolve the issue.
Use the billing-dispute address shown on the statement or issuer instructions, not an address used only for ordinary payments. Keep a copy and proof that the issuer received it.
The FTC guidance on billing errors says the issuer generally must acknowledge the dispute within 30 days unless it has already corrected the problem. It must resolve the dispute within two billing cycles, and no later than 90 days, after receiving the notice. During the investigation, FTC guidance says you do not have to pay the disputed amount or related finance charges, but you should pay the rest of the bill.
The CFPB's Regulation Z billing-error rule contains the governing federal requirements. This timetable does not automatically apply to debit cards, bank transfers, payment apps, or a marketplace's internal refund process.
PayPal and marketplace evidence
PayPal has its own purchase protection terms. PayPal's U.S. terms say eligible disputes must be opened within 180 days of payment. For certain disputes, the terms also use a shorter period tied to delivery or fulfillment, so the earlier applicable deadline can control. Read the PayPal U.S. Purchase Protection terms for the transaction and claim type.
Open the case inside your PayPal account, upload the clearest records, and keep the case number. A seller's promise to refund is useful evidence, but it is not the same as a completed credit on your account.
Amazon, eBay, and AliExpress can request different records for different orders. There is no universal proof list that guarantees a result. Use the platform's own case channel, preserve the order page and messages, and check the live deadline shown in your account.
If you paid through PayPal with a credit card, tell both providers about the other case. Keep the explanations consistent, and do not accept or request a double recovery.
Match the evidence to the problem
The order never arrived
Save the order confirmation, promised delivery date, tracking history, delivery address, and messages with the seller. If tracking says delivered but you did not receive the package, state that precisely and explain any carrier or delivery investigation.
A delivery scan can show a carrier event. It may not settle who received the package.
The item is defective, damaged, or not as described
Photograph the whole item first. Then capture close-ups of the defect, model or serial label, packaging, and any missing part.
Keep the listing that made the promise. Stop using an item that could be unsafe, and follow any seller or manufacturer return instructions without discarding the packaging.
The seller promised a refund
Save the message or email containing the promise, the promised amount, the date, and any return tracking. Then compare the expected refund with the later card or account statement.
A refund confirmation is evidence of an agreement. It is not proof that the money has posted.
You did not authorize the charge
This is a different route from a defective-item complaint. Contact the card issuer, bank, or payment provider promptly through a known phone number or official app, and follow its fraud process.
An unsolicited parcel also does not establish that you placed an order. Verify the account activity independently rather than using a phone number or link in a suspicious message.
Evidence mistakes that weaken a complaint
To be honest, most evidence problems are avoidable. The file is either too thin, too messy, or too late.
- A bank statement is submitted without the order details or product promise.
- A cropped screenshot hides the seller, date, amount, or order number.
- An edited image is presented as an original record.
- Messages are scattered across email, text, and several accounts with no timeline.
- The buyer waits for a seller reply until a platform or card deadline passes.
Never pay a supposed recovery agent by gift card, cryptocurrency, or wire transfer to release a refund. Support staff should not need your one-time security code or remote access to your device. Use the official site or app you open yourself.
When the first answer is no
Save the denial, closure notice, and reason given. Compare it with the purchase terms and your evidence, then ask a focused follow-up question rather than sending the same message again.
If the seller will not resolve the issue, use the marketplace or payment provider's formal escalation route before its deadline. A complaint to the FTC or a state consumer-protection office can create a record of a business practice, but it is not a guaranteed individual refund route.
For a larger amount, small claims court may be an option. Bring the same organized packet: proof of payment, the seller's promise, your notice of the problem, the response, and a clear calculation of what you are seeking. Court filing and service rules depend on your location.
Common questions
Is a bank statement enough to prove an online purchase?
Usually not by itself. It can connect you to the payment, but an order email, invoice, listing, or seller message should identify what you bought and what went wrong.
Do screenshots count as proof?
Yes, especially when they show the full page, account, date, order number, and seller. Keep the original email or downloaded document too, because screenshots can lose context.
What should I do if the seller says the package was delivered?
Save the carrier record, delivery address, tracking history, and your messages. Explain whether the address was wrong, the scan was premature, the package was missing, or someone else may have received it.
What is the credit-card dispute deadline in the United States?
For a qualifying billing error, written notice generally must reach the issuer within 60 days after the statement that first showed the error was sent. Other payment methods can use different procedures.
Can I complain to PayPal after the seller refuses a refund?
You may be able to open an eligible PayPal dispute, but the account terms and deadline control. Keep the seller's refusal and submit the transaction records through PayPal's case system.
