Making private label: what a retailer programme does to a factory

A listing is a capacity commitment before it is a sale

Winning a tender obliges the plant to hold volume available across the listing period, including promotional peaks that can multiply the weekly requirement for a short spell. The demand shape is a steady baseline with sharp spikes, and the retailer's availability target applies to both. Product families that suit the model are those where the recipe or specification is stable, the process well characterised, and the plant has enough line hours to absorb a peak without displacing other work. Handing more than a modest share of a line to a single listing removes the flexibility that made the factory attractive in the first place.

Open-book costing and the indexation argument

Retail buyers increasingly want the cost build shown: material at named specification, labour minutes, packaging, waste allowance, overhead recovery and an agreed margin. That transparency turns purchasing into a shared exercise — commodity movements settle against a published index on a review cycle rather than being argued case by case — but it also caps the upside from a good buying decision, because savings are visible and expected to pass through. Factories that accept open book without pinning down the indexation mechanism discover the ratchet only turns one way. Agreeing the review frequency matters as much as agreeing which index applies.

The retailer's technical standard sits on top of your own

Own-brand supply brings a second quality system into the building: the buyer's code of practice, its approved laboratory list, its unannounced audit programme and its specification format. These sit above whatever certification the factory already holds, and a non-conformance raised by a retail auditor carries commercial consequences that a certification body's finding does not. Specification control tightens noticeably — a change of ingredient origin or a packaging substitution needs written approval, and shipping outside the agreed specification is treated as a breach rather than a deviation. Complaint data flows back with the retailer's own severity coding attached.

Stock built against a promotion calendar

Production for a promotion is committed well before the offer runs, on the retailer's uplift estimate. Raw material and packaging are ordered against that estimate, finished pallets are built ahead, and when the uplift disappoints the surplus has nowhere to go: the packaging carries the retailer's name and cannot be sold elsewhere. Upstream suppliers therefore have to accept lumpy call-offs at short notice, which usually means paying for flexibility rather than taking the lowest quoted rate. Shelf life adds a hard deadline to the whole exercise, since aged stock is refused at the depot gate.

The cliff at the end of a tender

Growth in own-brand work is growth in dependency. Dedicated print plates, format parts and bespoke packaging tooling have no alternative use, and a lost tender strands them alongside the labour that supported the line. The characteristic collapse is a plant that filled itself with one retailer, held price through several review rounds, then lost the range to a rival and could not replace the volume before overhead recovery failed. Systems must handle electronic ordering, buyer-specific labelling and depot booking, while traceability has to be complete enough to answer a withdrawal question in hours rather than days.

Frequently asked questions

Can we supply our own brand and a retailer's brand from the same line?

Most retailers permit it, and many factories depend on the mix to keep lines loaded. What they will not accept is their specification quietly converging with yours, so expect explicit questions about how the two are kept distinct, how changeovers prevent carry-over, and whether the branded product takes priority when capacity is short. Put the allocation rule in writing before a shortage tests it, because that is precisely when the conflict surfaces.

How do we protect margin when the buyer can see our costs?

Negotiate the mechanism rather than the number. Agree which inputs are indexed, to what published series, how often the price is restated and whether movements travel in both directions. Keep genuinely proprietary elements — a process yield you improved, a co-product you sell — outside the disclosed model wherever the contract allows. And price the service separately: promotional flexibility, short lead times and bespoke pallet configurations consume line hours and belong on the invoice as line items, not as goodwill.

What should we do about tooling and packaging bought for a listing we might lose?

Establish ownership and an exit position at the outset. Retailer-funded artwork plates and format parts should be recorded as theirs and collected at termination; factory-funded items need either an amortisation recovered through the unit price over a stated minimum offtake, or a termination payment covering the unrecovered balance. Also agree what happens to specification-locked raw material and printed packaging already in the pipeline when a range is delisted at short notice.
