Case Packs for Retail: How to Choose the Right Quantity

By Martin Mecar, founderSeptember 24, 20266 min read

A case pack is the smallest quantity of one item a buyer can order. Choose it too large and independent shops cannot afford to try you. Choose it too small and your own shipping and handling costs eat the margin on every order. The right number comes out of three constraints meeting: what the shelf holds, what the buyer's cash allows, and what a carton can carry without falling apart.

Amazon sellers rarely have to think about this, because the marketplace sells in units of one. Wholesale sells in cases, and the case quantity ends up dictating your carton spec, your pallet pattern, your price ladder and the size of your minimum order. It is worth getting right before it is printed on anything.

Start from the shelf, not the container

The instinct from importing is to size cases for efficient freight. That instinct produces cases of forty-eight that no independent retailer will ever buy.

Work backwards instead. Ask how many facings your product would get in a target store and how fast it would turn. A specialty shop giving you two facings of a candle that sells one or two a week wants to hold maybe eight to twelve on hand. A case of six or twelve fits that. A case of twenty-four means the shop is buying three months of stock on a product they have never sold, which is a much harder yes.

For a chain, the calculation is per store rather than per order. They may order hundreds of cases in total, but each store receives a case or two, so the case still has to be a sensible quantity for one shelf.

There is a useful sanity check. If a single case is more stock than the store would sell in a quarter, the case is too big, regardless of what it does for your freight cost.

What a case has to cost the buyer

The second constraint is money, and it is blunt. The case value is what the buyer writes a cheque for per item, and independent retailers think in terms of an opening order they can risk.

Take a made-up product: a twenty-four dollar retail candle, wholesale at twelve dollars.

A first-time buyer taking three of your items at a case of six is risking a bit over two hundred dollars. At a case of twenty-four the same three items cost nearly nine hundred, and the conversation changes from a trial to a commitment. For a brand with no retail track record, the smaller case buys you far more accounts.

The counterweight is your own cost per order. If a six-unit case means picking, packing, labelling and shipping a tiny parcel for seventy-two dollars of revenue, you lose money on order handling. That is what minimum order values are for: a small case pack with a sensible minimum across items, rather than a large case pack that scares off the first order.

The physical limits

Three numbers constrain the case from the warehouse side, and all three are worth checking with your 3PL before you commit.

Weight. A case a picker has to lift repeatedly should stay in a range a person can handle safely. Heavy cases need to be smaller, or you will pay for two-person handling and see more injuries and damage.

Cube. The case has to stack into a pallet pattern with minimal wasted space. A case whose dimensions produce an awkward pallet layer costs you money on every freight shipment, because you ship air.

Board strength. Cases get stacked, cross-docked and sometimes shelved. Undersized corrugate is the leading cause of damage deductions, and the saving on board is smaller than one chargeback.

If the shelf quantity and the freight efficiency genuinely conflict, the answer is usually a middle layer rather than a compromise on either: inner packs inside a larger master carton, which is covered in inner packs and master cartons.

Different case sizes for different accounts

You can run more than one, but pay attention to what it costs.

A common structure is a small case for independents and a larger master for distributors, where the master is simply a multiple of the small one. That works because your warehouse only builds one object and groups it differently.

What does not work well is genuinely different case quantities per account, each needing its own carton size, its own markings and its own barcode. Every variant multiplies your printing minimums and your pick errors.

Larger retailers may dictate the case quantity to you, and there is limited room to argue. If a grocery chain says twelve per case with a specific case cube, that is the spec. Build to it and treat it as the standard rather than maintaining a second one for everyone else.

How case size drives your price list

The case quantity is the unit your price list is written in, which means it is also the unit your discounts are written in.

A workable ladder for a brand starting out: a single-case price, a better price at a few cases per item, and a distributor price at pallet quantities. The steps have to be justified by real cost differences — a pallet order genuinely costs you less per unit to pick and ship than a single case — or you are simply giving away margin. The wider pricing logic sits in wholesale pricing for Amazon products.

Watch the interaction with your marketplace price. If a distributor buying pallets gets a low enough price that they can resell profitably on Amazon, you have built a competitor to your own listing. Sellers who have lived through that describe the mechanics in wholesale customers reselling on Amazon.

What goes on the case

Once the quantity is fixed, the carton needs markings, and the buyer's vendor manual will specify most of them. The usual set is your company name, a plain item description, the item's manufacturer barcode, the case quantity, the buyer's item number, the PO number on the shipment label, and country of origin where required.

The case barcode itself deserves a decision. Some retailers want a separate case-level code so the carton scans as one entity in receiving; others scan a label carrying the shipping container code. The difference between an item barcode and a carton barcode is explained in GS1 barcodes for Amazon and retail.

Print the case quantity large and in a consistent place. Receiving clerks count cases quickly, and a carton that does not obviously state what is inside gets opened, which slows the delivery and sometimes fails it.

How to decide, concretely

Pick the quantity that satisfies the most constraints at once, in this order.

Start with the shelf holding quantity for a typical target store. Round to a number that divides cleanly into a pallet layer. Check the case weight is comfortable to lift and the case value is an amount a first-time buyer will risk. If a chain in your category publishes a standard case quantity, match it rather than inventing your own.

Then hold that number still. Everything downstream is built on it, and changing it after cartons are printed and price lists are out costs far more than the original decision.

If you are not sure what a typical target store looks like for your product, that is the thing to settle first. Paste your listing into WholesalePilot and the preview shows which retailers and distributors stock comparable items, which tells you whether you are sizing cases for boutiques, for a regional chain, or for a distributor moving pallets.
