Central Kitchen Inventory: Track Production, Dispatch and Outlet Receipts

Why central stock is harder to track

A central kitchen transforms ingredients into a finished item, holds it, moves it and hands it over. The finished sauce is a different stock item from the ingredients used to make it, even when both are measured in kilograms. Between dispatch and receipt it occupies an in-transit location rather than either kitchen shelf.

If the records do not reflect those stages, the same quantity can be counted at the central kitchen and at the outlet, or vanish while it is in a vehicle. Both problems make it impossible to tell whether a later difference came from yield, handling, recording or something else.

What food safety guidance expects of the records

FSSAI's guidance for food safety management in the catering sector describes keeping records of incoming material, production and dispatch, so that food can be traced backwards to its inputs and forwards to where it went. It also describes identifying and separating non-conforming product so it is not used until someone authorised has decided what happens to it.

That guidance is voluntary and the regulations prevail over it. A movement ledger supports traceability, but it does not certify compliance, guarantee the scope of any recall or replace the food safety controls and responsible people a business needs. Treat the ledger as one input to those controls, not a substitute for them.

Build the ledger around stable identifiers

Every record should point to something that does not change. Give each incoming lot of raw material an identifier from its receiving record. Give each production batch its own identifier, such as CK-1107-A for the first batch on 7 November. Give each shipment a dispatch reference that the outlet uses when it records the receipt.

Lineage is not always one to one. One ingredient lot may feed several batches, and one batch may draw on several lots of the same ingredient or be split across many shipments. Record those links explicitly rather than assuming a simple chain, because a later trace depends on them.

• Record each quantity in an approved base unit, with any conversion rule written down. If a pack size or a container is used, store the base-unit quantity alongside it.
• Weigh with a known tare and note the scale used, so a difference can be checked against method.
• Keep separate quantities for usable, held and in-transit stock. Never add them together without labelling each.
• Give work in progress and goods received but not yet checked explicit locations, so they are not missed at a cutoff.
• Correct errors with a reversal and a new entry, showing who authorised the change and why. Do not overwrite the original.

Worked example: one sauce batch

The figures here are illustrative only. Batch CK-1107-A uses 20 kg of raw recipe inputs, each linked to its receiving lot. After cooking, the finished sauce is weighed at 18 kg net of the container tare.

The 2 kg difference is a process and yield question. It may reflect expected evaporation or trimming in the recipe, or a measurement issue. It is not automatically spoilage, theft or a write-off. Compare it with the expected recipe yield and investigate an unexplained difference. Do not add the 20 kg of inputs and the 18 kg of sauce together as the same inventory: the inputs have been transformed into a different item.

In this example no production hold applies, so all 18 kg is released as usable finished stock. The kitchen dispatches 12 kg: shipment A of 7 kg and shipment B of 5 kg. The remaining 6 kg stays at the central kitchen. Until the outlets record their receipts, the 12 kg is in transit.

Outlet A checks its delivery, accepts 6.8 kg as usable and places 0.2 kg on hold pending assessment by an authorised person. Outlet B accepts all 5 kg.

Reconcile without double counting

A dispatch and its receipt are two halves of one movement, not two separate stock events. The dispatch moves quantity out of the central kitchen and into transit; the receipt moves it from transit into an outlet location. Neither creates stock.

For each shipment, pending quantity equals dispatched quantity minus received usable quantity minus received held quantity. In the example, shipment A is 7 minus 6.8 minus 0.2, which is zero, and shipment B is 5 minus 5, also zero. A pending quantity that stays positive after the expected arrival needs following up. An unresolved negative means something was recorded wrongly and must be investigated before the next cutoff.

The group check is simple: central usable plus outlet usable plus held plus in transit should equal released finished stock. Here that is 6 plus 11.8 plus 0.2 plus 0, which is 18 kg. The 0.2 kg on hold is still physical stock belonging to the group. It is unavailable for use, but it is not waste until the authorised assessment says so.

Use separate timestamps for dispatch and receipt, and agree a cutoff time for posting. A shipment dispatched before the cutoff and received after it should appear as in transit at the cutoff, not at both ends.

That recorded equation checks how the movements fit together; it is not independent proof that stock exists. At the same cutoff, count central and outlet usable stock and held stock separately, and confirm outstanding transit against dispatch and receipt evidence. Compare those independent checks with the recorded balance. This example stops before further use, returns or disposal. A later cutoff requires those movements too; otherwise a genuine use can appear as a shortage.

Traceability, recall and valuation

If an ingredient lot or a batch is questioned, the ledger shows where its outputs went. A food safety response should be led by the person responsible for food safety, using the records as evidence. Gaps in lineage tend to widen the scope of any action, because stock that cannot be linked to a lot cannot be ruled out. The records alone should never be used to declare stock unaffected or safe.

Keep the source evidence behind each entry, such as receiving notes, scale readings and signed receipts, along with the responsible person. Follow your own legal and food safety advice on how long to keep it.

A transfer to an outlet is an operational movement, not a retail sale. How transfers are valued, and how they are treated when the group's accounts are consolidated, is a policy decision for the accounts team.

Common mistakes

The most frequent mistakes are adding raw and finished weights together, recording a dispatch as if it were outlet stock, and leaving in-transit stock out of the count. Others include treating a yield difference as waste without investigation, writing off held stock before it is assessed, editing past entries instead of reversing them, and converting units informally on the spot.

A quieter mistake is assuming one batch maps neatly to one lot and one shipment. When lots are mixed or batches split, record each link. It takes a few more lines at the time and saves a great deal of guessing later.
