The second site is the one that teaches you what your supply chain actually was.
At one location, most sourcing problems are solvable by a person. The chef knows what is running low. Someone drives to a cash and carry when a delivery is short. Recipes live partly in a folder and partly in somebody’s head, and it works, because the person holding it all together is standing in the kitchen every day.
Open a second site twenty miles away and every one of those informal mechanisms stops functioning. Nobody notices what is running low, because nobody is in both kitchens. The recipe drifts, because the second head chef learned it slightly differently. Costs diverge, because the two sites are buying from different places at different prices.
This is not a failure of management. It is the predictable consequence of a system built for one location being asked to serve two. The businesses that scale well are the ones that rebuild their supply chain deliberately at each stage, rather than discovering it has broken.
Stage one: the single site
At one location, the supply chain optimises for flexibility. You want to be able to change your mind, try dishes, buy small quantities, and correct mistakes quickly.
The right structure here is a small number of accounts, frequent deliveries, and small pack formats. Cost per unit is relatively high and that is fine — the priority is learning what sells before committing to anything.
What you should be doing at this stage that most operators do not: writing recipes down properly, with weights and named products. Not because you need it now, but because the second site will be built from those documents. A recipe that says “soy sauce” rather than a specific product and quantity is a recipe that will taste different in every location you open.
Stage two: two to three sites
This is where most of the pain concentrates, and where the fixes are the least glamorous.
Consistency becomes the primary problem. The same dish now has to taste the same in two kitchens with two teams. This is decided overwhelmingly by ingredients rather than technique — if both kitchens use the same specified products, the dishes converge; if they source locally and independently, they diverge immediately and permanently.
Purchasing needs to centralise before you think you need it to. Two sites buying independently means two sets of prices, two stock positions and no visibility. Even a simple central ordering routine — one person places both orders on the same day from the same supplier — solves most of it.
Delivery logistics start to matter. Two locations means two delivery windows, two receiving procedures and two people who need to know how to check a frozen delivery properly.
The single most useful change at this stage is consolidating onto fewer suppliers who can deliver to all of your locations. A bulk food distributor in the UK with national coverage lets you place one order specification against multiple addresses, which is the difference between a supply chain you manage and one you chase.
Stage three: four to six sites
At this point, volume starts working in your favour — but only if the structure is right to capture it.
Pallet buying becomes viable. Core lines that every site uses — soy sauce, rice, noodles, oil, frozen staples — reach volumes where the unit cost drops meaningfully. Mixed pallets are the useful intermediate step: lower cost than case buying without committing to a full pallet of one product.
Storage strategy becomes a real decision. Do you hold central stock and distribute internally, or does every site receive directly? Central storage lowers unit cost and improves consistency but adds property cost, internal transport and a stock control function. Direct delivery to sites is simpler but forgoes some buying power. Most groups of this size run a hybrid: bulk core lines centrally, everything else delivered direct.
Specification control becomes formal. At six sites, “we use this brand of oyster sauce” needs to be written in a product specification list that new sites are opened against, not communicated verbally. This is also the point at which allergen documentation must be systematised rather than kept in a drawer.
Stage four: the central kitchen question
Somewhere around six to ten sites, most groups start considering central production — prepping sauces, marinades or components in one place and distributing them.
The arguments for it are real: absolute consistency, lower skill requirement in each site, better labour utilisation, and stronger purchasing power on raw ingredients.
The arguments against are equally real: capital cost, a distribution operation you now have to run, additional food safety complexity, and a loss of flexibility at site level.
The intermediate option that many groups underuse is buying quality prepared components rather than building a production facility. A well-made commercial base sauce, frozen dumpling or prepared aromatic delivers most of the consistency benefit of central production with none of the capital cost. For a growing group, this is frequently the better answer for several years longer than expected.
What to fix before you grow, not after
If you are planning your next opening, these five things are considerably cheaper to do now.
- Write specifications, not recipes. Every ingredient named by product and supplier, every quantity by weight.
- Consolidate suppliers deliberately. Fewer accounts, chosen for national coverage and range depth rather than the best price on any single line.
- Standardise receiving procedures. A written process for checking deliveries, particularly frozen and chilled, applied identically everywhere.
- Build a cost model per dish that updates. Growth exposes margin problems that were absorbable at one site.
- Ask your supplier what changes at higher volume. Pricing tiers, pallet options, delivery frequency and account management should all be discussed before you need them, not after.
The compounding advantage
The reason supply chain work is worth doing early is that its benefits compound in a way that most operational improvements do not.
A better unit cost applies to every case you buy for as long as you trade. Consistent specifications mean every new site opens faster than the last. A supplier who knows your business flags relevant new products rather than sending catalogues. None of it is dramatic in any single month, and all of it is decisive over five years.
Groups that scale badly usually do so because they treated procurement as an administrative function rather than a strategic one. Groups that scale well tend to have made their supply chain boring, documented and dependable well before they needed it to be.
