The 48 hours after Cyber Monday are when small problems are cheapest to fix and your information is freshest. Spend Tuesday on orders, stock and ads, Wednesday on customers, returns and your numbers, then make your Christmas decisions with dates against them.
After a hard match, good teams don't go straight back to training.
They have a recovery session. They check for injuries, they stretch, they rehydrate, and they review what happened while it's still fresh. It isn't glamorous, but it's what stops a small knock from becoming a three-month problem.
Black Friday and Cyber Monday are the same. By Monday night you're exhausted, the sales numbers are in, and there's a strong temptation to relax, or to rush straight into planning Christmas. But the 48 hours after the sale closes are when small problems are cheapest to fix and the best information is still available.
This is a checklist for those 48 hours. Block out Tuesday 1 December, and aim to finish by Wednesday night. It works whether you fulfil yourself or use a logistics partner, and it's built for founders building in public who have an audience waiting to hear how it went.

Because the problems from a big weekend don't stay still.
Must-Do Action:
Put the 48 hours in your calendar now, and clear Tuesday as far as you can.
Start with the thing that affects customers soonest.

What to check:
A backlog that's clearing is a good sign. One that isn't needs a conversation today, not on Friday.
If you use a logistics partner, ask these on Tuesday morning:
If you fulfil yourself, work out realistically how many orders you can ship each day this week, and be honest with customers if that's slower than promised.
Worth-Trying Tactics:
If some orders will be late, tell those customers before they ask. A short, honest message is better than silence.
Next, find out what you actually have.
What to check:
You're looking for differences between your records and reality. A small gap on a minor product can wait, but a gap on a hero product can't.
If you did find oversells, act quickly. Contact affected customers, offer clear options, and find out how it happened so it doesn't repeat. Our guides to ad-linked buffer rules and buying stock for peak cover the thinking behind this.
Must-Do Action:
Reconcile your top products, as a minimum. If you only have time to count ten lines, make them the ten that drive most of your revenue.
Now look at what's driving demand, and whether you can still support it.
What to check:
Look for spend that's still pushing demand you can't fulfil, and for messaging that's out of date.
Worth-Trying Tactics:
Pause or redirect ads for products that are running out. It's far cheaper than paying to acquire customers you can't serve.
Be careful about rescuing a quieter weekend by discounting. Check your margin first, and what the extra orders would cost to fulfil.
By Wednesday, the pattern of customer queries will be clear.
What to check:
You're looking for patterns. A cluster of "wrong item" messages points to picking. A cluster of "where is my order" points to dispatch or tracking. Each tells you where to look.
Returns often start earlier than founders expect, especially for gifts bought during the sale. Check your returns window and make sure customers can find it.
This part is easy to skip and easy to regret. Write down, today, the things you'll want in your debrief:
If you're building in public and want to share results, wait until the figures are checked, and only share numbers you're confident in.
Must-Do Action:
Write down what surprised you, while you remember it. It will be the most valuable part of your debrief.
With the facts in front of you, you can plan the next few weeks properly.
Write the decisions down, and put dates against them.
It's easy to treat the 48 hours as just more work. But if you've been running at full speed for weeks, you'll make poor decisions when you're drained.
Keep the checklist short, share it out if you have a team, and finish when you've finished. If people worked hard over the weekend, thank them properly and specifically. A quick 15-minute chat about what went well and what didn't is worth more than a long meeting later.
The weekend is the part everyone watches, but the days after often decide how the next four weeks go. A founder who spends 48 hours checking, fixing and planning heads into December with a clear picture and a proper plan.
If you stress-tested your set-up before the sale, you already know where to look. If you haven't, our 72-hour fulfilment stress test is worth keeping for next year.

Start with orders and dispatch: count what's still waiting to ship, find the oldest order and agree when the backlog will clear. Then reconcile stock on your top products, review ads against what you can fulfil, and tell customers whose orders will be late before they ask.
Plan for about two working days, Tuesday and Wednesday after Cyber Monday. Tuesday covers orders, stock and ads. Wednesday covers customers, returns, your numbers and your Christmas decisions.
Not before you've reconciled your stock and looked at what actually sold. Compare your records with the shelf, check for oversells, and then base reorders on sell-through and supplier lead times, making sure stock will arrive before your last Christmas order date.
Record orders each day against your forecast, your busiest day and hour, dispatch times, late or at-risk orders, picking and packing errors, support queries and their reasons, products that sold out, and ad results by campaign. Write them down while they're fresh, because you'll need them for your debrief.
Be careful. Check your margin first, including what the extra orders would cost to pick, pack and ship. If you do promote, make sure the stock and delivery dates can support it.
We've seen a huge surge in growth this year and whatever we throw at Zendbox, they work to support us. Order accuracy, shipping and communication has been spot on.

If you're looking for a logistics partner for your next peak, these are the numbers behind Zendbox's service.
Count unshipped orders, find the oldest, and agree with your logistics partner when the backlog will clear. Tell customers whose orders will be late before they ask.
Compare your system with the shelf for your top products and look for oversells. Then pause ads for products that are running out and update your delivery messaging.
Sort your customer queries, check returns have a clear policy, and record your orders, dispatch times, errors and what surprised you while it's fresh.
Choose your reorders, last order dates, December spend and capacity, and write them down with dates against them.
