What Shopify submits for you when a chargeback deadline passes — and what it leaves blank

Verified against a live Shopify Payments dispute and Shopify's documentation, August 2026.

If you sell on Shopify Payments, there's a detail in the chargeback flow that surprises a lot of merchants: you never "miss" a deadline in the sense of sending nothing. Shopify assembles a response from your store's data and files it on the due date whether or not you touched the case.

The banner on a disputed order says it plainly:

"Submit evidence by [date] to dispute the chargeback. After that, we'll send a chargeback response automatically to support your case."

And the evidence form carries an "Auto-submits on [date]" badge in the sidebar.

That's good news and a trap at the same time. Good, because a forgotten dispute isn't an automatic forfeit. A trap, because the automatic response contains only the things Shopify can look up by itself — and for most reason codes, those aren't the things that win.

What Shopify fills in without you

Per Shopify's documentation, the automatic response includes:

Product details — title, variants, quantity purchased
Shipping information — carrier and tracking number
Order fulfillment date and time
Shipping and billing addresses
Order placement date
Customer IP address and IP country

In the evidence form you'll also see a "Shopify provided evidence" block with AVS match, CVV pass, and customer IP address — the signals your acquirer already holds. For product not received disputes specifically, Shopify adds AI-generated insights to the submission, and there's an opt-out on the form if you'd rather they weren't included.

What stays blank unless you fill it

Open the form on a live dispute and the merchant-side slots read "Not provided":

Reason why the chargeback is invalid — a dropdown you select
Customer communication — emails, chat logs, the "where is my order" thread that ends with "got it, thanks"
Shipping documentation — delivery confirmation, signature, photo proof
Proof of service — for digital or service orders, usage, login or access records
Any other evidence that supports your case

None of that lives in Shopify's tables. If a customer told your support inbox the package arrived and then filed "item never received," that message is the single most useful document in the case — and the automatic submission will not contain it, because Shopify never saw it.

That's the actual gap. Not "Shopify doesn't respond." It's "Shopify responds with the shipping label, and the case turns on the email."

The form changed in December 2025 — worth a fresh look

If your mental model of the evidence form is older than that, it's out of date. The redesign added:

Reorganized layout that puts the essential fields first
A preview of the exact PDF that goes to the bank before you submit
An optional AI-assisted defense that combines your evidence with Shopify data to strengthen the document
The ability to submit earlier than the due date

One caveat on that last point, straight from the docs:

"You can choose to submit your response immediately after you save your evidence, or wait for Shopify to automatically submit it on the due date. If you submit your response early, then you can't make any further edits to your evidence."

So early submission is a one-way door. If you're still waiting on a carrier's proof-of-delivery scan, saving your evidence and letting the deadline handle submission keeps the case editable longer.

What Sidekick's "Help me respond to the claim" actually does

There's a button on the dispute with that label, and the reason code on the dispute record is clickable too. Both route into Sidekick, which — per Shopify's own description — "can help you understand disputes and provide guidance on how to respond."

Read that literally, because it's accurate: it explains what evidence tends to matter for that specific reason code. It does not write your narrative, gather your customer emails, or submit anything. It's a knowledgeable colleague, not a ghostwriter.

File requirements that quietly reject uploads

These trip people up at 11pm on deadline day:

Only PDF, JPEG, or PNG are accepted
PDFs must be PDF/A compliant
Each PDF must be fewer than 50 pages
Each file 2 MB or less
All files combined 4 MB or less

Shopify also recommends high-contrast images that print legibly in black and white — because a fair number of banks still receive chargeback evidence by fax. A beautiful screenshot with light-grey text on white is, functionally, a blank page by the time an analyst sees it.

A practical order of operations

When the dispute lands, open the evidence form and read the customer's claim verbatim. The reason code alone hides the specific accusation.
Pull the customer communication first. It's the highest-value item and the one Shopify can never supply.
Fill the reason dropdown and the narrative to answer that claim, not chargebacks generally.
Attach documents inside the file limits, in high contrast.
Save the evidence — but don't submit early unless everything you're waiting on has already arrived.
Check the generated PDF preview. It's what the bank actually reads.

None of this requires a tool. It requires knowing that the blank slots are the whole game, and that the deadline will pass with them blank if you don't act.
