When Should You Raise or Lower an Inventory PAR Level?

The Answer Up Front

Raise a PAR level when you have two to three consecutive weeks of sustained usage increase, when you are repeatedly running out before the next delivery, or when your delivery schedule has lengthened. Lower a PAR level when you have two to three consecutive weeks of sustained usage decrease, when you are consistently overstocked, or when a product is approaching expiration while sitting on the shelf. Never adjust a PAR based on one unusual week.

Signals That It Is Time to Raise a PAR

Raising a PAR level is not something you do because you are worried about running out. It is something you do because the data shows your current level is no longer sufficient. Here are the concrete signals:

• Repeated stockouts: You run out of the item before the next delivery two or more times in a month. One stockout might be a fluke. Two stockouts means your PAR is too low for your current usage.
• Sustained usage increase: Your rolling average has climbed for three consecutive weeks and shows no sign of dropping. This is a real trend, not an outlier.
• Delivery schedule change: Your supplier switched from twice-weekly to once-weekly deliveries. Your PAR needs to cover the longer gap between orders.
• New business pattern: You added a menu item, a service, or a promotion that permanently increases demand for an ingredient or supply.
• Seasonal transition: You are entering your busy season and historical data shows usage typically increases by a specific percentage.

When you raise a PAR, do it gradually. A 10% to 20% increase is usually enough to start. You can raise it again if the trend continues. Big jumps create overstock just as easily as stagnant PARs create stockouts.

Signals That It Is Time to Lower a PAR

Lowering a PAR is harder for most operators because it feels like taking a risk. But carrying excess inventory is expensive. It ties up cash, takes up space, and increases the chance of waste. Here are the signals:

• Consistent overstock: Your ending count is consistently above 80% of your PAR level. You are carrying more than you need.
• Sustained usage decrease: Your rolling average has dropped for three consecutive weeks. Business has slowed, a menu item was discontinued, or demand has shifted.
• Expiration risk: Product is approaching its expiration date while still on the shelf. This is a clear sign that your PAR is too high.
• Storage constraints: Your back room is full and you are struggling to find space for new deliveries. Some of your PARs are probably higher than necessary.
• Seasonal transition: You are exiting your busy season and historical data shows usage drops predictably.
• Delivery schedule change: Your supplier switched from once-weekly to twice-weekly. You no longer need to carry as much buffer stock.

When you lower a PAR, draw down your existing stock first. Do not lower the PAR and then immediately throw out product. Stop ordering the item until your current stock approaches the new PAR level. Then resume ordering to the lower target.

What Not to Do

Do not adjust based on one week. One high week or one low week is not a trend. It is noise. Wait for two to three consecutive weeks of sustained change before you move a PAR. The patience prevents you from chasing every fluctuation.

Do not adjust everything at once. If you think multiple PARs need changing, change them one at a time or in small groups. Changing your entire inventory system in one week makes it impossible to tell which adjustment worked and which did not.

Do not forget to document. Write down why you changed the PAR and what you changed it from. Six months later, when you are reviewing seasonal patterns, you will want to know whether the adjustment was based on data or on a hunch.

The Review Rhythm

Set a calendar reminder to review all your PAR levels monthly or quarterly. Do not wait for a crisis. A proactive review catches drift before it becomes a stockout or an overstock. During the review, look at each item's rolling average compared to its PAR. If the average has shifted by more than 20% for two consecutive months, the PAR probably needs adjustment.

How TrackItWeekly Helps You Time PAR Adjustments

TrackItWeekly shows your rolling three-week usage average next to every item's PAR level. When the average has climbed steadily for several weeks, the gap between average and PAR shrinks, and the color coding flags the item for attention. This visual cue tells you when an adjustment is worth considering.

The app stores your PAR history, so you can see when you last changed a level and what you changed it from. This prevents the common mistake of adjusting the same PAR up and down repeatedly without realizing it.

Seasonal multipliers make temporary adjustments easy. Instead of manually changing fifty PAR levels for holiday season, you apply a 1.5x multiplier to all of them. When the season ends, you remove the multiplier and return to baseline. No individual PAR changes required.

TrackItWeekly does not automatically adjust your PAR levels. The judgment call is always yours. But it gives you the data and the history to make that call with confidence instead of guessing.
