When a retail buyer nods and smiles at larger pack sizes with a variety of flavors, it feels like the break you’ve been scrapping for. But then reality hits. The first invoice from your copacker practically gives you a heart attack. The pallet gets rejected at the D.C. because you missed a single best-by date in the lot code. Guess what? The drink was the easy part… the numbers get real complex once you start multiplying ingredients.

The SKU count multiplies faster than you think
A 12-pack with four flavors is not a single product; it’s five products: four unique flavors and the variety pack. Each of those needs its own UPC, its own label artwork, its own nutritional panel, and its own spot in your inventory by pack size. Then your understaffed forecasting ‘team’ (who you should be giving a raise now for having to put up with your variety pack nonsense) has to predict demand for five things instead of one and hope that people buy the bundle at the ratio you need them to. They won’t.
This combining of SKUs is the starting point of every other unforeseen problem on this list. More SKUs mean you’re more likely to over forecast something, more likely to have a box scanned incorrectly, more likely to get a deduction because something was off in the compliance guide. Whoever put all their cash into ingredients instead of their operating line will have a harder time of it when they discover each additional SKU amplifies all of those risks fivefold.
Why this catches founders off guard
When founders are starting off, they test out their flavors one by one, not by four. So they have no actual concept of the fact that they will need to run production on all four of those flavors, and therefore the four-pack, at the same time, in the same pool of labor, through the same compliance checks. It doesn’t seem like something that would be hard to figure out. You made the four packs this week, why not the two-packs next week and so on for whatever flavors you have. Startup leaders frequently overlook this because a variety pack isn’t a bundling decision – it’s a parallel production decision, and parallel production is where small teams break.
Line changeover costs you didn’t budget for
Changeover time can be more negotiable than you’d think. Some co-packers have entire wet-fill lines dedicated to single clients; those clients lock in pre-build schedules that the co-packer staffs accordingly to make up for the low utilization rate. If you’ve got the volume to commit, or are willing to pay a premium for guaranteed slots without some complicated volume commitment, smaller players especially might be willing to haggle on changeover costs.
The same goes for line configuration – a flex line that can handle both bottles and cans (and possibly even other formats)? You get charged for that versatility in a variety pack because you’re paying the depreciation on lidding machines, the oven drier, and the seamer once per item produced per annum whether you use them or not. In theory, your can is left sitting in a warehouse during bottling or vice versa – but that doesn’t mean you’re not covering the cost of its use. If a co-packer wants to hit your numbers, they can be a bit looser with what specifically is amortized over your planned run.
MOQs turn a launch into a cash-flow problem
Co-packers establish minimum order quantities in order to ensure that a production run is long enough to cover the changeover and labor costs. Unfortunately, this means that you will need to have a substantial amount of cash to pay for the order because you are likely to have paid your co-packer a minimum of $100,000 before receiving payment from a retailer for your first case order – assuming that you even get orders.
When you are ordering a multi-SKU variety pack, you may also be required to order four flavors, pay bundling minimums, and pay for secondary packaging materials to be ordered in bulk. You might have to take this requirement even further if there are any multi-sizing MOQs.
The temptation is to overcommit. The retailers want you to deliver the variety pack by a certain date, the co-packer requires an MOQ, you sign a purchase order the size of the co-packer’s MOQ because you want to look like a good customer, and when the product underperforms you are losing the margin on five SKUs, not just one. You are also losing prime sales time, not just time your cases spend sitting.
Secondary packaging is a different job than filling
Competence at filling a can or bottle and competence at bundling four flavors into a shrink-wrapped variety pack are not the same discipline. Secondary packaging – shrink film, cartons, tray packs, club-store display shippers – requires different equipment, different labor skills, and often a different part of the facility than the filling line. A lot of co-packers are excellent at high-speed filling and mediocre, or entirely unequipped, for multi-flavor bundling.
When your co-packer can’t handle secondary packaging, you’re now shipping filled product to a second facility for bundling. That’s added freight, added lead time, and – critically – an added handling touchpoint where damage happens. Cans get dented in transit between facilities. Cartons get crushed on a dock waiting for a truck. Every extra handoff is a place where your margin leaks out through breakage, delay, or a mismatched delivery window that costs you a display date.
This is the single most overlooked filter when brands are choosing a production partner for a variety pack launch. A co-packing partner with packaging and warehousing under one roof eliminates the handoff problem entirely – filled product goes straight into bundling without leaving the building, and the same team that’s accountable for fill quality is accountable for the shrink-wrap and case pack that show up on the retailer’s dock. If you’re vetting co-packers for a variety pack specifically, ask about secondary packaging capability before you ask about fill speed. Fill speed doesn’t matter if the bundle falls apart in transit.
Pallet math and retail compliance will erase your margin
Retail buyers do not give marks for effort. They have a routing guide with the exact number of cases, the number of layers, and shipping container display specifics, and an incorrect variety pack leads to a chargeback – that’s a fee or penalty directly subtracted from your invoice, usually by surprise. The promotional margin that you expected to make on the order is wiped out by one wrongly configured pallet.
Also, mixed-flavor bundles tend to occupy more space than uniform cases. A pallet of a single flavor is easy to arrange; a pallet of mixed bundles is less easily arranged, particularly if the flavors are packed in cans of different sizes or the carton of the bundle is not identical to the case of the single flavor. Fewer units per pallet result in a higher freight cost per unit, a cost that is not indicated in the manufacturing quotation that you received but one that directly affects your profit margins.
Shelf life compounds this. Beverage products, especially anything cold-chain or shelf-stable with a defined freshness window, don’t forgive uneven sell-through. If one flavor in your pack is clearly the favorite, it sells out of the bundle faster at the shelf level even though it’s locked into the same case with three slower flavors. The slow flavors age. Eventually they get marked down or written off, and that write-off eats into a margin that looked fine on the spec sheet.
This is the mechanism behind a number that should scare anyone treating a variety pack launch casually: out-of-stocks and overstocks cost global retailers an estimated $1.1 trillion a year (IHL Group). A poorly forecasted variety pack feeds both ends of that number at once – stockouts on the flavor that’s moving, and write-offs on the flavors that aren’t, inside the same bundle, on the same pallet, at the same time.
The bullwhip effect hits variety packs harder
Retailers prepare seasonal display windows well in advance. And when a fad hits, the reorder signal races back up the pipeline and grows bigger at every turn – the classic bullwhip effect. The effect is even greater for a variety pack, because a spike in demand doesn’t just require more cans; it requires more cans in four flavors, more shrink film, more cartons, and a longer lead time for every one of those components to meet the particular display date set by the retailer.
If your co-packer’s lead time on film or cartons is longer than the retailer’s window for the promotion, you are out of stock precisely during the week the display is in the store and traffic is highest. That’s the worst possible time to be out, and it’s the most common situation with variety packs, since the component list is longer and slower than for a single-SKU order.
Start smaller than you want to
The solution to most of these issues does not involve more funding, but rather, practicing self-restraint. For example, instead of introducing five different flavors, start with a three-flavor pack. Before considering a fourth flavor, make sure the sell-through is verified after two complete product display cycles. This is your opportunity to evaluate whether your co-packer, 3PL, and your internal demand planning system have the capacity to manage a multi-product SKU before expanding the product count.
A variety pack looks like a marketing decision. It’s actually a stress test of everything behind the label – production, packaging, warehousing, and the compliance gate at the retailer’s dock. Brands that treat it that way going in tend to still be on shelf a year later. Brands that treat it as a bundling exercise usually aren’t.
