Case quantity is the number of units inside one shipping carton, and it is the wholesale decision small brands make most carelessly. Whatever number fits neatly in the box you already buy tends to become the case, and then that number quietly sets your minimum order, your freight cost per unit, your handling margin and the size of the commitment a new shop has to make.
A sparkling tea brand sells cans at five dollars retail and two fifty wholesale, twelve to a case, so a case is thirty dollars. Landed cost is a dollar fifteen a can. Every question below is about whether twelve is the right twelve.
What the number is actually doing
Four jobs at once, which is why it is hard.
It is the order increment. A shop that wants eighteen cans has to buy twelve or twenty-four. The bigger the case, the coarser the choice you are forcing on them.
It is the shelf unit. Twelve cans is roughly one facing deep on a chilled shelf for a week in a small shop. Twenty-four might be two weeks, which for a dated product starts to matter.
It is the freight unit. Cartons are priced by size and weight. Twelve cans in a carton that sits comfortably under a parcel carrier's weight break costs one thing to ship; twenty-four in a heavier carton may cross into a different rate and cost more than twice as much.
And it is the handling unit. You pack one carton, print one label and count one line whether it holds six cans or twenty-four. Every unit you add spreads that fixed cost thinner, which is the single strongest argument for larger cases and the one that has to be balanced against all the others.
Working the arithmetic
Run the tea at twelve and at twenty-four.
At twelve: case value thirty dollars, cost of goods thirteen dollars eighty, carton and divider a dollar ten, and perhaps ten minutes to pick, pack and label. Shipping a single twelve-can carton domestically might be eleven dollars. If you absorb that freight, the case leaves you around four dollars.
At twenty-four: case value sixty dollars, cost of goods twenty-seven sixty, carton about a dollar seventy rather than double, and roughly twelve minutes rather than twenty. Freight on the heavier carton might be sixteen dollars rather than twenty-two. Absorbed freight and all, the case leaves you closer to fourteen dollars.
The larger case is dramatically better for you, and that is exactly why you should be suspicious of your own reasoning. The question is not what the case does to your margin. It is whether a shop will place an order at all.
Where the buyer's limit sits
Three constraints decide the buyer's answer, and only one is about money.
Shelf space. A small shop has a set number of facings. If twenty-four cans will not fit behind one facing, the shop has to store the rest in a back room they may not have, and a product that lives in a back room stops being reordered.
Sell-through time. For anything dated — food, drink, skincare, anything with a best-before — the case has to sell through comfortably inside its life with room for the shop to feel safe. A shop that sells six cans a week will take twelve without thinking and hesitate at twenty-four.
Cash for the first order. A new stockist wants to try three or four of your lines, not one deep. If each case is sixty dollars and your minimum is four cases, the trial costs them two hundred and forty dollars. At thirty a case the same trial is a hundred and twenty and gets said yes to far more often. That is the trade at the heart of opening order.
The rough rule that falls out: set the case so a typical shop in your target type sells through it in two to four weeks. Faster and they run out between orders, slower and the product looks dead on the shelf.
Inner packs solve most of the tension
The way out of choosing between twelve and twenty-four is often both: a master case of twenty-four made of two inners of twelve.
The shipping carton holds twenty-four, which is what your freight and handling want. The inner of twelve is the smallest quantity a shop can buy, and it is also the unit that goes out on the shop floor without repacking.
That gives you three useful positions. Small accounts buy inners and mix across flavours to reach your minimum. Larger accounts buy full cases and get the better handling economics passed on through a quantity tier. Distributors buy full cases only.
Inners cost a little more in packaging and are worth it in almost every category with more than a handful of variants. The one place to avoid them is where the inner is not shelf-ready — an inner that has to be cut open, unpacked and flattened by the shop is just a box inside a box. The broader mechanics of how the layers relate are in case pack.
Choosing a number that is not arbitrary
Start from the shelf, not from the carton.
Ask what one facing of your product looks like in the shops you are targeting. For the tea that might be six cans across a chilled shelf edge. Multiply by how deep the shelf runs, usually two, and you have twelve as the natural shop-floor unit.
Then check three practical things. Does twelve fit a standard carton size your supplier already stocks, because bespoke cartons at low volumes are expensive. Does the packed weight stay under the point where your carrier's rate steps up. And is twelve divisible in ways that help, which is why six, twelve and twenty-four are so common — they split cleanly into halves and thirds for inners and for sampling.
Avoid numbers that look considered and are not. A case of ten is tidy in a spreadsheet and awkward on a shelf. A case of seven happens when someone measured a box. A case of five in a category where everyone else ships six makes your line sheet harder to compare, and buyers compare.
Case quantity and the minimum order are different decisions
Brands conflate these constantly and it costs them orders.
The case quantity is how the product is packed. The minimum order is how much of anything a shop has to buy to be worth serving. The first is a physical fact about your carton; the second is a policy about your time.
For the tea, a sensible pair is a case of twelve and a minimum of four cases, or a hundred and twenty dollars, mixed freely across flavours. That gives the shop real choice while making sure each order covers the cost of existing. A minimum expressed in dollars rather than cases is usually better for exactly that reason — it lets a buyer build the assortment they want. The reasoning behind that number is in minimum order quantity.
Where it goes wrong is a large case plus a high case-count minimum. A case of twenty-four with a four-case minimum is two hundred and forty dollars of one flavour range and reads as a brand that does not want small accounts, which may be true but should at least be deliberate.
Changing it later
Case quantities are stickier than prices. A shop that has built a reorder rhythm around twelve will notice the week it becomes twenty-four, and an increase almost always reads as a price increase even when the unit price has not moved.
If you have to change, change it between seasons, tell accounts before they next order rather than in the carton, and hold the unit price steady through the change so the only variable is the pack. If the change is upward, consider introducing an inner at the old quantity so nobody is actually forced to double their commitment.
The change that goes down is easier and is worth considering more often than brands do. Cutting a case from twenty-four to twelve halves the barrier for every new account while costing you a few dollars of handling per order, and for a brand trying to win its first twenty stockists that is usually a good trade.
If you are not sure what size of account you are packing for, paste your store or product link into WholesalePilot and look at the preview of retailers and distributors that stock comparable products. Whether that list is mostly single-location shops or mostly multi-site buyers should decide your case before your carton supplier does.
Questions brands ask about case quantity
Should every product in the range have the same case quantity? Ideally the same or a simple multiple. Mixed quantities across a range make order forms harder to fill in and invoices harder to check.
Can a shop buy a single unit? Sometimes, for high-value items, and it is worth allowing explicitly rather than by exception. For anything under about twenty dollars retail, single-unit picking costs more than it earns.
Does the case need a barcode of its own? For independents, rarely. For chains and distributors, a case-level code is often required, and it is easier to add at the start than to retrofit.
How does case quantity affect the price tiers I publish? It sets the units the tiers are counted in, and tiers should always be stated in cases rather than units so nobody has to convert. The design of those breaks is in volume discounts.
