  3. Black Friday chargebacks (UK)

"Black Friday went great. Then the chargebacks arrived in December." A UK merchant playbook.

Big BFCM weeks mean more orders, more gifts shipped to other addresses, more "delivered but I never got it" and more friendly fraud. For a UK or EU Shopify store each card dispute pulls the money and a fee straight away, and the evidence window is short. Here is the clock, the evidence pack, the "not received" reason code we could source, and what to set up before Black Friday week. Facts from Shopify Help and the Visa Dispute Management Guide for Merchants (October 2026), checked 5 Nov 2026. Not legal advice.

Why BFCM spikes chargebacks for UK and EU stores

When the cardholder's bank opens a chargeback, Shopify says the bank "takes the disputed amount from you right away" and "also takes a chargeback fee". An inquiry doesn't take the money or fee straight away (Shopify Help: chargebacks and inquiries). We did not find a published GBP/EUR fee figure we could verify, so check your Shopify Payments payout or your processor's fee schedule.

The Shopify response deadline

Shopify says "the deadline is typically 7 to 21 days after the chargeback is filed", and with Shopify Payments "you can submit evidence up until the due date listed on the chargeback. When the due date has passed, you can't submit further evidence. The result of the chargeback is final" (Shopify Help: resolving chargebacks). Shopify also says it automatically populates available data and sends a response on the due date, and that bank review "can take up to 30-90 days".

Practical rule for BFCM: the due date on each chargeback in Shopify admin is your real deadline. Don't plan around 21 days; some will be 7.

The evidence pack for "Product not received"

Shopify's advice: contact the customer first. If they agree to drop it, ask them to tell their bank and include evidence of that in your response. If not, submit proof they received it before the chargeback: fulfilment date and time, billing info, shipping and tracking. Shopify "will automatically upload a PDF containing all fulfillment events" (Shopify Help: chargeback reasons).

Visa's guide says a valid proof of delivery for physical goods should include:

Add your customer chat or email thread if the buyer confirmed the gift address or acknowledged delivery. For gift orders, the delivery address must match what was entered at checkout, which is why the shipping address on the order matters.

UK and EU notes

Prevention before BFCM week vs fighting after

Before Black FridayAfter a chargeback lands
Use tracked services with photo POD or signature on high-value ordersPull POD, delivery photo and address match the same day
Make your statement descriptor recognisableContact the buyer; many "unrecognised" cases drop once they remember
Review Shopify high-risk orders and cancel the bad ones (Shopify suggests this)Submit before the due date in Shopify admin
Consider a network dispute-resolution / alert programme that refunds before a chargeback forms (Shopify mentions these)Accept the ones you can't prove; fighting without POD rarely wins

Tools when volume outgrows a checklist

Chargeblast focuses on dispute alerts so you can refund before an inquiry turns into a chargeback (and a fee). Useful when BFCM volume spikes.

See Chargeblast dispute alerts affiliate link

Chargeback.io automates chargeback responses and alerts for Shopify stores.

See Chargeback.io affiliate link

Disputifier is another Shopify chargeback-automation option.

See Disputifier affiliate link

Many chargebacks start as a "where is my parcel" claim. Claimify, our own Shopify app, logs not-received, lost and damaged claims with photos and outcomes so you have the record before a bank asks. Selling on TikTok too? See TikTok Shop item not received for sellers.

Who should skip the tools

Verdict

Treat every BFCM chargeback as a dated job: read the reason, contact the buyer, build a pack with address-matched POD and photo, and submit before the due date in Shopify (typically 7-21 days). For volume, add dispute alerts (Chargeblast) or automation (Chargeback.io), and log not-received claims early (Claimify). Not legal advice.

FAQ

How long do I have to respond to a chargeback on Shopify?

What is Visa reason code 13.1?

Merchandise/Services Not Received: the cardholder says they did not get what they paid for. Visa says you must show the goods were delivered, made available or used as agreed.

The full delivery address matching the invoice, courier delivery status, and optionally a recipient signature and delivery photo, per Visa's Dispute Management Guide for Merchants (October 2026).

What are the Mastercard and Amex codes for not received?
