Restaurant par levels: set stock targets that protect cash and service
Set replenishment targets from usage, delivery intervals, a measured buffer and shelf life. Order only the gap after stock and confirmed deliveries.
A par level is the stock target for the time until the next delivery. Use four weeks of daily usage to estimate demand, then allow for busy services and delivery delays. A par target is a planning number, not a measure of ingredient loss.
The working method
- Cycle stock is average daily usage × days until the next delivery. Include the supplier's lead time when deciding when to place the order.
- Safety stock covers demand variation or a late delivery. Set it from observed peaks and delays; a 15% buffer is an example, not a universal rule.
- Usable stock excludes expired, damaged or reserved product. Count open packs in the same unit as the purchasing record.
- Round orders to the supplier's pack size only after subtracting stock and confirmed deliveries. Check that the rounded quantity can be used before expiry.
- A stock target is not theoretical consumption. Investigate an unexplained consumption variance separately instead of treating usage above par as loss.
A worked example
The kitchen uses 18 kg per day. Deliveries are two days apart, the buffer is 15%, and chicken comes in 7 kg cases.
| Cycle stock | 18 × 2 = 36 kg | Demand until the next delivery |
|---|---|---|
| Safety buffer | 36 × 15% = 5.4 kg | Target before rounding: 41.4 kg |
| Practical par | 6 × 7 = 42 kg | Check storage and shelf life |
| Order today | 42 − 14 − 7 = 21 kg | 14 kg usable stock, 7 kg confirmed incoming: order 3 cases |
Recalculate after a demand or delivery change. Count the stock first; ordering six cases every time would duplicate the stock already available.
Keep the routine
- 1Measure usage. Record daily usage for four weeks. Mark holidays, events and shortages so unusual days do not silently set the target.
- 2Set the coverage period. Record the delivery interval and order lead time. Confirm the next delivery date before each order.
- 3Count and calculate. Count usable stock, check incoming orders, then calculate the gap. Keep units and pack conversions explicit.
- 4Review weekly. Compare shortages, leftovers and waste with the target. Adjust the buffer for evidence, not one noisy service.
Frequently asked questions
FAQ
- Is par the same as a reorder point?
- No. Par is the target after replenishment. A reorder point tells you when stock is low enough to place the order, allowing for lead time.
- Should every item have a 15% buffer?
- No. Use observed demand and delivery risk. Perishables may need a smaller buffer or more frequent deliveries.
- How often should I count?
- Check high-value and perishable items weekly and complete a full month-end stocktake. Count critical items before ordering.
- Can I use a spreadsheet?
- Yes. Keep item, unit, usage, coverage days, buffer, par, usable stock, incoming quantity and order quantity on one sheet.
