For many small stores, a few weeks around the end-of-year holidays or a big sale event bring a large share of the year’s orders. Those weeks are also when problems cost the most: a stockout on your best seller, a theme change that breaks the cart, a packing backlog that turns into a wave of late deliveries.
Most of what makes peak season go well happens before it starts. This guide works backward from the busy period with a timeline, then covers stock, staffing and fulfillment, the store itself, shipping cut-offs, marketing and what to do during and after.
Key takeaways
- Work from last year’s data where you have it, adjusted for what has changed since.
- Order stock on your suppliers’ timelines, not yours, with extra lead time for their busy season.
- Line up help and supplies before you need them, and test the packing routine at higher volume.
- Finish theme, app and checkout changes early, then freeze.
- Write customer messages in advance: cut-off dates, delay notices and returns terms for gifts.
A working timeline
The timings below are a hypothetical example for a store whose peak is in late November and December. Shift them to match your own peak and your suppliers’ lead times.
| When | Focus |
|---|---|
| About 4 months before | Review last year, draft a sales estimate, talk to suppliers about lead times and capacity |
| About 3 months before | Place main stock orders; plan promotions and gift ranges |
| About 2 months before | Finish theme and app changes; audit apps; test checkout and speed; order packing supplies |
| About 6 weeks before | Line up and train extra help; write customer messages and saved replies |
| About 4 weeks before | Store freeze begins; publish cut-off dates; check stock arrivals against plan |
| Peak | Daily stock and order checks; follow the routine; urgent fixes only |
| After | Returns, stock review, notes for next year |
Stock
Estimate demand
Start with last year’s sales for the same period, by product and variant if you have it. Then adjust for what has changed: products added or dropped, a larger email list, different promotions, prices. If you have no history, use recent monthly sales and treat any peak multiplier as a guess to be cautious with. Our guide to simple demand forecasting explains moving averages and seasonality without special software.
A hypothetical example: a product that sold 40 units in last year’s peak weeks, and has grown modestly since, might be planned at somewhat more than 40, with a reorder decision point set in advance rather than a much larger order up front.
Order early and in layers
- Ask suppliers about their own peak. Factories, wholesalers and freight all get busier at the same time you do. Lead times that are reliable in spring may not be in autumn.
- Order core sellers first, then add riskier or new products in smaller quantities.
- Set reorder points with extra safety stock for the period. Our guide to reorder points and safety stock shows how to calculate them, including for variable lead times.
- Decide on preorders or waitlists for items you know will sell out, so demand is captured rather than lost.
Do not overbuy
Extra stock that does not sell in the peak can sit for months. Be cautious with seasonal items that will be hard to sell in January, and plan in advance what you will do with leftovers: bundles, a planned markdown with an end date, or holding them for next season if you have the space.
Check counts before the rush
Make sure inventory numbers are right before the busiest weeks, especially for best sellers. Overselling during the peak means cancellations at the worst moment.
Staffing and fulfillment
- Estimate the workload. If a normal day is a set number of orders and you expect several times that, work out how many packing hours that means.
- Line up help early, whether family, friends, temporary staff or a fulfillment service. Check the employment and insurance rules that apply.
- Train before the rush. Give new helpers the routine, the packing standards and a few practice orders.
- Pre-assemble what you can: fold boxes, prepare inserts and gift notes.
- Order packing supplies early. Boxes, mailers, tape and label rolls run short across the market in busy periods.
- Make the station bigger, or set up a second one if two people will pack.
Our order fulfillment workflow guide explains how to set up the routine and packing station that the extra help will follow.
The store itself
Finish changes, then freeze
Any change to the theme, apps or checkout carries a risk of breaking something. Make the changes you need well before the peak, test them, and then stop.
- No new apps or theme updates during the freeze, unless they fix a real problem.
- Keep a copy of the working theme so you can roll back quickly. Our guide to backing up your store data covers theme copies and exports.
- Write down who can make changes and how urgent fixes are approved.
Audit and test before the freeze
- Apps: remove ones you no longer use, check what each one bills, and ask the developers of apps you rely on how they handle busy periods.
- Speed: test your busiest pages on a phone. Promotions often add banners, pop-ups and scripts that slow things down.
- Checkout: place test orders with each payment method and shipping option you offer, including discount codes and gift cards.
- Discount logic: test that codes combine, or do not, the way you intend, and that automatic discounts end on time.
- Product pages: check stock status, delivery estimates and gift-related information.
Prepare pages and messages
- A shipping page with cut-off dates for each delivery option.
- A returns note for gifts, such as an extended window if you offer one.
- Saved replies for common questions: will it arrive in time, can I change my order, can I add a gift note.
- A delay notice template, ready to use. See how to tell customers about shipping delays.
Shipping cut-off dates
Carriers usually publish their own recommended last posting dates for the holiday season. Use them as a starting point, then build in your own dispatch time and a margin.
| Step | Example |
|---|---|
| Carrier’s recommended last posting date for a service | A date the carrier publishes |
| Minus your dispatch time | If you dispatch within 2 working days, subtract 2 working days |
| Minus a margin | A further day or two, as a rule of thumb |
| Your published cut-off | The date you show customers for that service |
Publish cut-offs on product pages, in the cart, in an announcement bar and in your emails. After the cut-off, say clearly that orders may not arrive in time, rather than hiding it.
Marketing
- Plan dates and offers in advance, with clear start and end times.
- Warm up your email sending if you will send far more than usual, and make sure your domain is authenticated. See email deliverability basics.
- Only email people who consented to marketing, even in a busy season.
- Do not promote products you cannot ship in time. Pause campaigns for items that sell out or arrive late.
- Keep reference prices honest. Many places have rules about “was” prices during sales, so check the rules where you sell.
During the peak
- Check stock and orders daily, and hide or mark products as sold out promptly.
- Stick to the routine: fixed cut-off, fixed handover time, exceptions shelf.
- Tell customers early if anything slips.
- Keep a short daily log of problems and decisions. It is the most useful input for next year.
After the peak
- Process returns quickly and restock what can be resold.
- Review stock: what sold out, what is left, what to clear.
- Lift the freeze and make the changes you postponed, one at a time.
- Write a short summary while it is fresh: what worked, what to start earlier, what to stop.
FAQ
How early should I start preparing?
It depends mainly on supplier lead times. If you buy from overseas or have products made to order, start several months ahead. If you reorder locally within days, you can start later, but the store freeze and staffing still need a few weeks.
Should I run a big discount?
Not necessarily. Discounts bring volume, which needs stock and packing capacity, and they cut margin. Some stores do better with gift ranges, bundles or free gift wrapping than with deep discounts.
What if a key product sells out mid-season?
Mark it as sold out right away, offer a waitlist or a clearly dated preorder if restock is possible in time, and point shoppers to alternatives.
Bottom line
Start with last year’s data and your suppliers’ lead times, order stock early and in layers, and line up help and packing supplies before you need them. Finish theme, app and checkout changes early, test them, then freeze. Publish shipping cut-off dates with a margin, write customer messages in advance, and keep a daily log so next year’s preparation starts from what actually happened.
