Christmas: when to cut your budget before the shipping deadline

The budget cut is set in the warehouse, not in the account

You cut your Google Ads budget before Christmas on the day from which a new order no longer arrives before Christmas Eve. That day follows from three quantities that Google does not know: your carrier's drop-off deadline per destination country, the time your warehouse needs from order to handover, and a buffer for bottlenecks. The formula:

Last order day = carrier drop-off deadline − warehouse time − buffer

Up to that day, every click is a potential Christmas present. After it, part of the demand keeps buying, but with the risk of cancellations and returns because "it arrived too late". If you set the budget by the calendar ("quieter from the 20th") instead of by the last order day, you either give away the strongest days or pay for clicks you cannot fulfil.

Which deadlines the carriers name for 2026

The carrier deadlines are the fixed part of the calculation. As of early November 2026, DHL and Swiss Post name these dates:

On 24 December, DHL by its own account does not usually collect anything any more. For other carriers and for shipping within Austria, the deadline your provider gives you applies. If you use several shipping methods, you calculate with the slowest one that comes into question for a product.

Switzerland needs its own end date

Switzerland is the case where a uniform account setting fails. For shipping from Germany, DHL closes one day earlier for Swiss recipients than domestically, and customs clearance comes on top. DHL advises sending the EDI data including customs data in good time before drop-off. If it is missing, the parcel sits at the border and your buffer is used up. For Swiss orders I would therefore plan at least one more working day of buffer than for Germany.

The reverse is even more extreme: a retailer with a warehouse in Switzerland who delivers into the EU is already finished with Swiss Post at the beginning of December. For that shop, Christmas business in the EU is an extension of Black Week, not a December sprint. This affects budget planning for the whole month, not just the last days.

A rule for the account follows: every delivery country with its own shipping deadline needs its own campaigns, or at least its own budgets. A campaign that targets Germany and Switzerland together cannot be cut back on two different dates.

Worked example: a shop in Germany with two countries

Suppose a shop ships from Germany with DHL Paket, the warehouse needs one working day from order to handover and works Monday to Friday. As a buffer, the shop plans half a day.

• Germany: handover by Tuesday, 22 December at the latest. Minus one working day of warehouse time gives Monday, 21 December. With the buffer, the last order cut-off is Monday, 21 December, at midday.
• Switzerland: handover by Monday, 21 December at the latest. Minus one working day of warehouse time gives Friday, 18 December, minus one working day of customs buffer gives Thursday, 17 December. The order cut-off there is Thursday evening.

In this example, the two countries are around four days apart. The weekend makes things tighter: orders placed on Saturday only go out on Monday if the warehouse does not work weekends.

Reduce, do not switch off

On the cut-off day you cut the budget of the affected product campaigns and leave the bid target as it is. According to Google, budget changes do not trigger a learning status with Smart Bidding and take effect in the next auction. For target changes, by contrast, Google advises against making several within one conversion cycle. If you raise target ROAS for the last days and lower it again in January, you introduce exactly that unrest. How much and how often you should touch a target at all is covered in Changing target ROAS.

I consider a hard pause the worse variant. After the shipping deadline people still buy, just for delivery after the holidays or for themselves. That demand is smaller and worth less, but not zero. A clearly reduced budget with an unchanged target lets Smart Bidding take the remaining good auctions and keeps the campaign warm for January. I would not cut brand campaigns at all: people searching for your shop are often searching for the voucher.

If you expect a clearly lower conversion rate for the days after the shipping deadline, that is a case for a negative seasonality adjustment. According to Google, it suits periods of one to seven days, it may work less well beyond 14 days, and it is intended only for substantial changes. It is available for Search, Standard Shopping and Display campaigns with target ROAS or target CPA, and for Performance Max. The time between the shipping deadline and 24 December fits this window. Whether the effort pays off depends on how strongly your range depends on gift buying.

Say the shipping deadline in the ad

The ad should state the order deadline before the customer finds it on the product page. For this, responsive search ads have the countdown customiser: it counts down to a set point in time, starts five days before if you give no value of your own, and after the end date, ads with a countdown automatically stop showing. If you set the countdown to your order cut-off, the delivery promise ends by itself, and you do not have to swap texts at midnight.

For Switzerland, the countdown ad gets the Swiss end date, not the German one. Alongside it, a second ad without a countdown belongs in the ad group, to take over after the cut-off date: "delivery after the holidays" or a pointer to the voucher. You switch the shop banner and the shipping information on the product page at the same time, otherwise the page promises what the ad has already withdrawn.

Why the last days before the cut look bad

Just before the shipping deadline, the numbers almost always look weaker than they are. According to Google, conversions can be reported up to 90 days after the click, depending on the conversion window. The costs of the last days are already in the report, but part of the orders are not. If on 18 December you look at the week's ROAS and tighten the target as a result, you are reacting to a measurement gap. You measure how large the gap is for you with the segment "Conversions > Days to conversion". For that, the report's date range must end at least 30 days before the day of the analysis, so last year's December is suitable. More on this in Conversion delay.

That also answers the question of what happens to conversions after the cut: they keep coming in. Clicks from the week before the shipping deadline still produce orders days later. A campaign with a reduced budget therefore looks better in retrospect after Christmas than on the day of the cut. Evaluate December no earlier than mid-January.

Are vouchers worth it after the shipping deadline?

From the shipping deadline onwards, the digital voucher by email is the only product you can still deliver on time. The demand is there: in an EY survey of more than 1,000 adults in Germany, gift vouchers or cash were the most popular Christmas present at 48%. Part of the reduced product budget therefore belongs in a small search campaign on voucher searches for your brand and your category, with a landing page that says "instantly by email" on the first screen.

Two caveats, in my assessment. First: a voucher sold is not yet contribution margin, which only arises on redemption, and part of the redemptions replace purchases that would have come anyway. You should therefore not compare the ROAS of a voucher campaign with that of the product campaigns. Second: without notable brand awareness, search volume is small. In that case it is enough to put the voucher ad into the brand campaign instead of building a campaign of its own.

When this calculation does not apply

Working back from the deadline applies to ranges where the purchase before Christmas depends on the gift. If you sell consumables, spare parts or B2B supplies, you lose hardly any demand after the shipping deadline and only have to state the delivery date honestly. If you offer your own couriers, same-day delivery or pickup in store, you have a later deadline or none for those routes. And if you run budget-limited in December anyway, the cut gives you room that you can put into the days up to the shipping deadline beforehand. How to spread the budget across the season is covered in Planning your budget across the year. What has to be ready beforehand is covered in Black Week preparation.
