Stocking for the school season without dead stock in October

Buy stationery to a season curve built from your own past months, not last month alone. A planning table, a worked example and mistakes that leave dead stock.

To stock for the school season without dead stock afterwards, buy to a season curve built from your own past months, not from last month's sales. Work out what share of each item's yearly sales falls in each month, plan the season order against that curve, and split it into a first order plus top-ups you confirm against early sales. Slow down your buying before the peak ends, not after it.

Why is last month's sales a bad guide for school stock?

Because the school season is a spike, not a trend. Last month's sales describe a quiet month just before the rush, or the peak itself. Neither tells you what the next month will look like.

Plan from the quiet month and you run short when parents come in with their lists. Plan from the peak and you keep ordering at peak rates after demand has already dropped. That second mistake is the one that fills your shelves with notebooks, geometry boxes and covers that nobody buys until next year.

A stationery shop sells two kinds of stock. Some items, like pens, refills, A4 paper and files, sell all year with a small bump in season. Others, like school notebooks of a set size, covers, labels, school bags and certain art supplies, sell almost entirely in a short window. These two kinds need different plans.

What is a season curve and how do I build one?

A season curve shows, for one item or group of items, what share of a typical year's sales happens in each month. You build it from your own sales records, not from anyone else's numbers.

Pull monthly sales by item for the last one to three years. Use quantities, not rupees, so price changes do not bend the shape.
Group similar items. Plan one curve for "long-ruled notebooks" rather than one for every page count and brand. It is steadier and easier to keep up to date.
Turn each month into a share of the year. Divide that month's quantity by the year's total. If you have more than one year, average the shares.
Mark the months that matter: the build-up, the peak, the tail and the quiet months.
Apply the curve to this year's expected total. If you expect to sell a similar volume to last year, the curve tells you roughly how much you need each month.

If your local schools changed their book lists or a big shop opened nearby, adjust the expected total. Keep the shape unless you have a real reason to change it.

What does a season planning table look like?

Here is a planning table for a school-season item group. The months are numbered from the start of your own rush, because the calendar differs between boards, states and towns. Fill in the months from your own sales history.

Season month	Phase	Buying action	Stock target
Month −3	Quiet	Review last season's curve, clear leftover stock, agree rates and returns terms with suppliers	Normal all-year stock only
Month −2	Pre-season	Place the first season order for slow-lead-time and imported items	Season-only items start to arrive
Month −1	Build-up	Receive and shelve, place first order for local items, set temporary reorder points	Cover for lead time plus the opening weeks
Month 0	Peak	Daily or weekly check against the curve, release planned top-ups only if sales are on track	Enough for the peak, no more
Month +1	Tail	Stop top-ups for season-only items, reorder all-year items at normal rates	Let season stock run down
Month +2	After-season	Count what is left, move or bundle leftovers, note what went wrong	Back to normal levels
Remaining months	Quiet	Buy all-year items on normal reorder points	Normal all-year stock only

The key line is month +1. Most dead stock is bought in the tail, when the shelf still feels busy and the last top-up looks safe.

Can you work an example?

All numbers below are illustrative, not drawn from any real shop.

A shop sold 2,000 long-ruled notebooks last year. Its own records show this curve: 5% in month −1, 45% in month 0, 20% in month +1 and 30% spread evenly over the other nine months.

The owner expects a similar year, so:

Month −1: 2,000 × 5% = 100 notebooks
Month 0: 2,000 × 45% = 900 notebooks
Month +1: 2,000 × 20% = 400 notebooks
Every other month: about 67 notebooks

The distributor takes ten days to deliver. Instead of ordering 1,400 notebooks at once, the owner orders 550 before month −1, covering the build-up and the first half of the peak. Two top-ups of 225 each, for the second half of the peak, are planned but only confirmed if sales in the first two weeks of the peak are on track.

Sales in the first two weeks come to 350 against an expected 450. The owner releases one top-up, cancels the other and orders the month +1 quantity in small lots. The season ends with a little over a month's normal stock of notebooks left, not several hundred.

Set temporary reorder points for the peak using the same method as our post on the reorder point formula, with peak-month daily sales and the lead time your suppliers really give you in season. Then reset them when the peak ends.

How should I work with distributors around the season?

Your supplier has the same rush, so lead times usually get longer just when you need stock most. Measure your own lead times from last season's purchase orders, not the normal months.

Talk to your distributor in the quiet months about:

Split deliveries, so you can confirm a large season order in parts.
Returns or exchange terms for unopened season-only stock, agreed in writing before you buy.
Pack sizes, because a case of 200 on a slow variant can become dead stock on its own.

If you are on the distributor side, the same curve applies to your parties' orders. Our guide to wholesale distributor inventory covers how to plan stock across many retailers who all want stock in the same few weeks.

What are the common mistakes?

Planning from the previous month. A pre-season month says nothing about the peak, and the peak says nothing about the tail.
Placing one big order. It locks in your guess before any real demand shows up.
Topping up in the tail. By the time the shelf looks thin, demand is already falling.
One curve for everything. All-year items and season-only items need separate plans.
Ignoring leftovers. Stock left over from last year should come off this year's order before you buy anything.
Forgetting longer lead times. Normal-month lead times underestimate the season.

When does this not apply?

A season curve needs a repeatable pattern. It works less well for:

New items with no history. Borrow the curve from a similar item and order small.
Bulk orders from a school or institution. Treat a confirmed order as a separate purchase, not part of the curve.
Shops that changed location or customer base. Older history may describe a different business. Use the latest season and adjust quickly.

Your all-year items still follow normal reorder points. The curve is for what spikes.

FAQ

How many years of sales history do I need to build a season curve? One full year is enough to start, and two or three years give a steadier shape. If you only have one year, treat the curve as a draft. Watch the first few weeks of the next season closely and correct the remaining orders against what you actually sell. Do not stretch one unusual year into a rule.

What should I do with school-season stock left over after the rush? Separate it into items that sell all year and items that only sell in season. Keep the all-year items in normal stock. For the season-only items, bundle them, offer them to schools or offices, or ask your distributor about returns while the packs are still in good condition. Then cut next year's order for those lines.

Should I place the whole season order in one go? Usually no. Place a first order for the opening weeks and keep the rest as planned top-ups that you confirm against early sales. The first order covers the lead time and the start of the rush. The top-ups let you follow real demand instead of a guess you made weeks earlier.
