PAR vs reorder point
If you've spent any time in restaurant kitchens, you've heard "PAR." If you've spent any time in a retail warehouse or with an ERP, you've heard "reorder point." They're the same idea expressed in different vernaculars.
Where each word came from
PAR in the restaurant context is commonly said to stand for "Periodic Automatic Replacement" — though most operators who use the word have never heard that expansion and don't care. It's more usefully thought of as a golf reference: the score you want to hit. Your PAR is the target; you're either over or under.
Reorder point comes from inventory management theory in retail and manufacturing. It's the level at which you trigger a new purchase order. In a fully-integrated retail system, hitting the reorder point automatically fires an order to the vendor.
Where they differ — the one nuance
In a textbook retail / e-commerce setup:
- You have a reorder point — the stock level that triggers the order
- You have a reorder quantity — how much to order when triggered
- Orders fire automatically when on-hand ≤ reorder point
In a typical restaurant setup:
- You have a PAR — the target post-order stock level
- You count periodically (weekly)
- You order the gap between count and PAR, manually
The math is the same. The workflow is different: retail systems watch continuously; restaurants count discretely.
Which word to use
A practical guide:
| Audience | Use |
|---|---|
| Your staff | PAR |
| A vendor rep selling to restaurants | PAR |
| A restaurant-industry article or consultant | PAR |
| A vendor portal designed for retail (has a "reorder point" field) | reorder point |
| Generic inventory ERP | reorder point |
| A software contract or RFP | both, defined as synonyms |
What isn't the same
Things people sometimes conflate with PAR that are not PAR:
- Safety stock. A component of PAR, not the whole thing. Your PAR includes safety stock.
- Min/max. Some systems use a min/max pair (min = reorder point; max = order-up-to level). In restaurant PAR language, the PAR is the max; the min is implicit (below it, you're at risk of 86-ing).
- Order-up-to level. Technically a different concept in inventory theory, but in restaurants it's effectively the same as PAR when using Formula 2 from how to calculate PAR.
- Usage forecast. Your forecasted weekly usage is an input to PAR, not PAR itself.
The bottom line
If you're running a QSR, say "PAR." Your staff will know what you mean. Your vendor rep will know what you mean. Your customer (who doesn't care either way) won't hear the word at all.
Par Inventory uses the restaurant vocabulary throughout — PAR, count, cases, shortfall. Not because retail language is wrong, but because we built it for operators who already speak one language, not two.
