Par Level
What is a Par Level?
A par level is the amount of a product you aim to have on hand at all times.
It’s your target inventory level. When you drop below it, you reorder.
If your par for tequila is 6 bottles, the goal is to always have about 6 bottles in stock—not 2, not 12.
The Basic Idea
Par Level − Current Inventory = What You Need to Order
Example:
Par level: 6 bottles
Current inventory: 2 bottles
You order 4 bottles to get back to par.
Why It Matters
Par levels are what keep your bar from constantly running out of things or overstocking.
Without them:
you run out of key ingredients mid-service
you tie up cash in excess inventory
ordering becomes reactive instead of planned
different managers order completely differently
Par levels turn ordering into a repeatable system instead of guesswork.
How to Set a Par Level
At a basic level, a par should cover:
how much you use
how often you order
a small buffer
A simple way to think about it:
Par = (Usage over a period) + Safety buffer
Example:
You go through 4 bottles of vodka per week
You order once per week
You want a small cushion
Your par might be 5–6 bottles
That gives you enough to operate without running tight.
What Actually Affects Par Levels
Par levels aren’t static. They depend on how your bar operates.
Things that matter:
sales volume
how often you place orders
delivery schedules
storage space
seasonality
menu changes
how predictable your demand is
A busy weekend bar and a slower cocktail lounge shouldn’t have the same approach.
Common Mistakes
Setting it once and never updating it
Par levels should change as your menu and sales change.
Ignoring ordering frequency
If you order twice a week, your par should look different than if you order once.
No buffer at all
Running too tight leads to stockouts. Something always goes wrong eventually.
Too much buffer
Over-ordering ties up cash and creates waste, especially with perishable items.
Treating everything the same
High-volume items need tighter control than slow-moving ones.
Par Level vs Inventory
Inventory is what you currently have.
Par level is what you want to have.
The gap between the two is what drives your ordering.
If you don’t have a defined par, your inventory numbers don’t really tell you what to do next.
Par Level vs Inventory Variance
Par levels help you manage ordering.
Inventory variance helps you catch problems.
If your par says you should be fine, but you’re constantly running out early, something’s off—either your par is wrong or you have shrinkage or tracking issues.
What a “Good” Par Level Looks Like
There’s no perfect number.
A good par level:
keeps you from running out
doesn’t leave you sitting on excess stock
fits your ordering schedule
adjusts as your business changes
If you’re constantly scrambling or constantly overstocked, your pars need work.
One Thing Most People Miss
Par levels are only as good as the data behind them.
If you don’t know your actual usage, you’re just picking numbers that feel right.
That’s why par levels work best when they’re based on:
real sales data
consistent inventory counts
updated recipes and usage
Otherwise, you’re just replacing one guess with another.
When to Adjust Par Levels
menu changes
seasonal shifts (busy vs slow periods)
changes in ordering schedule
new suppliers or delivery timing
noticeable overstock or stockouts
If your ordering feels off, your pars probably are too.

Bottom Line
Par levels give you a simple system for knowing what to order and when.
Without them, you’re reacting. With them, you’re planning.
They don’t need to be perfect—but they do need to be intentional and updated over time.
