Black Friday shipping: handle the peak before it hits your warehouse
Black Friday falls on Friday 27 November this year, Cyber Monday on Monday 30 November. That week, the pressure moves from your webshop to your warehouse, and then on to your carriers, across every market you ship to.
Data from the Wuunder Parcel Radar shows where delays build up, what the peak adds to your costs and what you can arrange now.

Black Friday 2026 day by day: from Black Week to the December rush
| Date | Moment (2026) | What happens | What the Parcel Radar showed in 2025 |
|---|---|---|---|
| Mon 23 Nov | Black Week starts | More and more retailers stretch their discounts across the whole week. | Order volume was 152% above normal all week. Expected delays ranged from 13.8% to 22.3% per day. |
| Fri 27 Nov | Black Friday | The order peak of the week. In Belgium, the bpost peak surcharge starts today. | 232% more orders expected than on an average day. 23.4% of Black Friday orders were expected to arrive late. |
| Sat 28 + Sun 29 Nov | Weekend | Customers keep ordering while many warehouses are closed. | 5.3% (Saturday) and 6% (Sunday) more orders than the same weekend in 2024. The busiest hour of the whole week was Sunday evening between 7 and 8 pm. |
| Mon 30 Nov | Cyber Monday | Weekend orders and new orders land at the same time. | 454% more warehouse orders expected. This single day accounted for 26.9% of all processing between 24 November and 5 December. Carriers were expected to run 24% delays. |
| Tue 1 to Fri 4 Dec | Four working days before Sinterklaas (Sat 5 Dec), the Dutch and Belgian gifting peak. | For parcels collected from Black Friday onwards, delays rose to 30%, peaking at 55.3%. | |
| Wed 2 Dec | last order date for Sinterklaas (advice) | Last day to order and ship, before your warehouse cut-off. Thursday 3 December already carries a serious risk of delay, Friday 4 December is too late. Show this date in your checkout, emails and banners. | After Black Friday, delays rose to 30%. Don't count on next-day in these days. |
| Sat 5 Dec | Sinterklaas | Last delivery day before gift evening in the Netherlands, with no evening delivery. If the gift arrives late, the buyer grabs an alternative in a shop at the last minute and sends the online order back. You lose the sale and pay for transport twice plus a surcharge. | In 2025, Cyber Monday fell on 1 December, just before Sinterklaas. Weekend orders, Cyber Monday orders and the last online gift orders for Sinterklaas all landed that day, making it by far the busiest warehouse day of the peak. |

Five places where the peak gets stuck
The peak doesn't hit one spot. It moves through the whole chain: from checkout to warehouse, carrier, customer service and finally returns. The more orders you ship per day and the more countries you ship to, the harder each step gets squeezed.
Peak season surcharges 2026: what does a parcel cost extra?
At peak, you don't just get more orders, you often pay more per parcel too. Carriers add peak surcharges on top of your rate and fuel or energy surcharge. Every carrier and market uses different periods, so a parcel shipped on 20 November can be surcharged in one country and not in the next.
| Carrier | Market | Surcharge | Period |
|---|---|---|---|
| PostNL | Netherlands + Belgium, including returns | € 0,32 per parcel | 15 November to 31 December |
| bpost | Belgium, domestic parcels | €1.00 per parcel (excl. VAT) | 27 November to 25 December 2026 |
| DHL Paket | Germany | €0.19 per parcel, plus a €0.50 Peak-in-Peak surcharge in the busiest weeks | November and December; Peak-in-Peak dates on dhl.de |
| DHL Express | Global | Demand Surcharge per kg | International 1 October 2026 to 5 February 2027, domestic 1 November to 31 December 2026 |
| UPS | Global | Last published: €7.25 extra per Additional Handling parcel and €75.85 per Large Package (from NL) | Last season: 28 September 2025 to 17 January 2026 |

How to limit the extra cost:
- Shipping to Belgium? The bpost surcharge starts on Black Friday itself. Orders you ship on Thursday 26 November are not affected.
- Defer shipments with GreenChoice. Let customers choose a later delivery day at checkout, optionally with a shipping discount. That can be a few days later, or a few weeks: until after your carrier's surcharge period. Do the maths: a €1 peak surcharge on a €15 shipment adds almost 7% to your transport costs. It also saves on temp staff in your warehouse. More about Best Day Delivery.
- Compare all-in. Wuunder includes virtually all surcharges per shipment when comparing carriers, so you see what a parcel really costs in every market.
- Stop shipping air. PuzzlPack picks the smallest box per order and avoids large-parcel surcharges.
- Audit your invoices after the peak. 2 to 5% of carrier invoices contain errors (Wuunder data). Wuunder Track data lets you match delivery times and attempts against your invoice.
Checklist: what you can arrange now
Now: October to early November
- Pick your peak strategy. One big day or a longer deal period? A longer period spreads the pressure.
- Check your discount claims. In the EU, a discount must be based on the lowest price you charged in the 30 days before. If your Black Week starts on 23 November, your prices from late October count.
- Scale fulfilment before Black Friday. Restock based on expected sales and plan extra warehouse capacity.
- Line up a backup carrier per market. Wuunder compares rates and services across 300+ carrier connections, without shipping rules to maintain. See all carriers.
- Offer a later delivery moment at checkout with Best Day Delivery.
Two weeks before: from mid-November
- Fix your cut-off times per market and show them in checkout, emails and on your site. For Sinterklaas in the Netherlands and Belgium: make Wednesday 2 December your last order date, as gifts shipped on Thursday 3 or Friday 4 December run a serious risk of arriving late.
- Show a delivery time you can keep at peak. Can't guarantee next-day? Add deferred delivery in your checkout.
- Freeze your checkout. No new releases until after Cyber Monday.
- Set up proactive tracking emails. Wuunder Track cuts 'where is my parcel' questions by up to 70%.
- Subscribe to the Parcel Radar to see where delays build up during the peak.
During Black Friday week
- Plan for the weekend. In 2025, the busiest hour of the week was Sunday evening. All those orders land on Monday.
- Track delays per shipment. Wuunder customers see in their dashboard which shipments are running late.
- Keep customers informed. Wuunder Mailer automatically follows up shipments with recipient, carrier and sender.
After Black Friday: Christmas and returns
- Expect a second peak. In 2025, the last order peak was expected on 22 December, with 45% more orders than average.
- Make returns easy. With Wuunder Returns, customers return without a label and refunds go faster.
- Audit your carrier invoices for duplicate or incorrect surcharges.
Spread the peak in your checkout, not in your warehouse
Next-day as the default pushes your volume to Monday in the warehouse and Tuesday at the carrier. With Best Day Delivery, your customer picks a delivery day when the carrier is already in the area. Next-day stays available for anyone in a hurry. 88% of consumers voluntarily choose the green delivery day. For Neleman, that led to 30% higher conversion (research by the University of Groningen).
At peak, you can go one step further. Not every customer is in a hurry, especially those buying Christmas gifts in November. Offer them a delivery moment a few weeks out, after the peak and after your carrier's surcharge period, with a shipping discount as a reward. You don't have to pack those orders during the peak. You need fewer temp staff and pay no peak surcharge on those shipments.
"I believe we'd benefit from shifting towards a 'Black,' or even better, 'Green,' Wednesday. Having a peak on Wednesday distributes the pressure more evenly for warehouses and carriers."

Your busiest days are decided in the checkout
Every Monday, the same thing happens: the entire weekend hits your warehouse floor at once. In some sectors, more than 41% of the week's volume lands on a single morning. And peak season hasn't even started yet.
We analysed 14 sectors and found peaks of up to 8x a normal day. But we also found something else: one setting in your checkout that cuts the Monday peak by almost 10 percentage points. No extra staff, no extra warehouse space, and no extra effort for your customer.
Which sector gets hit hardest, and why do 88% of customers voluntarily play along? Find out in the onepager.
