🇨🇳 中文版本： 如何通过 Refund Stacker 门户上传文件
⏰ Deadline reminder: Walmart sets hard deadlines on every document request. Missing the deadline forfeits the claim permanently. Upload as soon as you receive the request.
Uploading through the portal is faster and more reliable than emailing files. Your documents are logged instantly, your case manager is notified automatically, and there is no risk of attachments getting lost or buried in an inbox. Most uploads take under two minutes.
Your documents are transmitted securely and are only accessible to the Refund Stacker team handling your account.
After logging in, click Document Requests in the sidebar, or navigate to refer.refundstacker.com/doc-requests.
You will land on the Open Requests tab, which lists every shipment waiting on a document from you.
New to the portal? Your login credentials are the same ones you use at refundstacker.com. If you have not received credentials yet, contact your account manager.
The table shows:
| Column | What it means |
|---|---|
| Shipment ID | The Walmart shipment reference (e.g. 6756674WFA) |
| Case ID | The dispute case number, if already opened |
| Document Needed | What we need: BOL, POD, etc. |
| Status | Open = action needed. In Case Management = received, being worked. Expired = deadline passed, claim forfeited. |
| Deadline | The date Walmart requires the document by. Do not miss this date. |
| Uploads | How many files you have already attached |
Use the search bar at the top to find your shipment by ID or case number.
Click the blue Manage Documents button on the row for your shipment. A modal will open.
For a BOL request:
For a POD request:
You can upload revisions at any time while the request is still Open. Just click Upload revision on the relevant row. You can also delete an upload if you made a mistake.
Uploading from a phone or tablet works the same way. Use your mobile browser and log in as normal.
Once all documents are attached, click Send to Case Management at the bottom of the modal.
This hands the package to our team and locks the upload. After this, no further changes can be made. If you uploaded the wrong document or need to make a correction, contact your account manager directly and do not open a new request.
If you are not ready to submit yet, click Save for later. Your uploads are saved and you can come back at any time before the deadline.
You will receive a confirmation email once your submission is received. If you do not see it within a few minutes, check your spam folder.
After you click Send to Case Management:
The Library tab (next to Open Requests) shows all documents you have ever uploaded, so you can find and re-download them any time.
| Shipment Type | What to Upload |
|---|---|
| WPC — Parcel (small pack) | Packing list only (prepared by Refund Stacker, no upload needed from you) |
| WPC — LTL or FTL | Bill of Lading (BOL) |
| Non-WPC (FedEx, UPS, other carriers) | Proof of Delivery (POD), one per tracking number |
| Non-WPC with disputed delivery | POD + Bill of Lading (BOL) |
Invoices are not required for any claim type.
I got an email from my case manager asking for a document. What do I do?
Log in, go to Document Requests, find the shipment mentioned in the email, and follow the steps above. You do not need to reply to the email with attachments.
The shipment is not showing up in my Open Requests list.
The request may have already been resolved, or it may not have been created yet. Reply to your case manager's email and let them know. They will check the status.
My upload keeps failing.
Make sure the file is a PDF and under 25 MB. If the problem continues, email the document directly to your case manager and note that the portal upload is not working.
The request shows "In Case Management". Do I need to do anything?
No. That status means our team received your documents and is processing the claim. We will reach out if anything else is needed.
The request shows "Expired". What does that mean?
The Walmart deadline passed before the documents were submitted. Unfortunately the claim window has closed for this shipment. Contact your account manager if you have questions about next steps.
I uploaded the wrong document after clicking Send to Case Management.
Once submitted, uploads are locked. Contact your account manager immediately with the correct file and they will handle it on their end.
I have a consolidated shipment with multiple case IDs.
Upload documents under each case ID separately. Each row in your Open Requests list corresponds to one case. If you are unsure which document goes with which case, ask your account manager before uploading.
