Most restaurant operators know they should be tracking PAR levels. Fewer have a system that actually keeps those numbers current as sales mix shifts and ingredient prices change. See how R365’s inventory and purchasing tools and suggested ordering reports automate the process so operators stop guessing and start ordering from real data.
As of October 2026, a PAR level is the ideal amount of inventory you need to have on hand to get through until the next delivery without running out or wasting food. That definition is simple. Living by it, across dozens of ingredients and multiple locations, is not. Most restaurant operators still rely on gut feeling or outdated spreadsheets to decide when and how much to reorder, which leads to waste, stockouts, and margin erosion. The right restaurant management software connects your POS sales data to your inventory counts, calculates what you actually need, and generates purchase orders before you run short. This article walks through how PAR levels work, how to calculate them, which tools automate the process, and what real operators have gained by doing so.
For a broader foundation on inventory management, see R365’s complete guide to restaurant inventory management and food inventory management: tools and best practices for restaurants.
In practice, most operators think of a PAR level as a target number: the minimum quantity of each item you should have on hand at any given time. Drop below it, and you risk 86’ing a menu item during a Friday rush. Sit too far above it, and you are paying to store food that may spoil before it sells.
The standard formula is straightforward:
Normal inventory used per week + safety stock = PAR level
Safety stock acts as a buffer against delivery delays, unexpected demand spikes, or supplier shortages. A common guideline is to set safety stock at 10–20% of average inventory usage for a single item, depending on how volatile that item’s demand is and how reliable your supplier tends to be.
Most restaurants target 5 to 7 days of inventory on hand. That range balances two risks: tying up too much cash in walk-in cooler stock, versus running out mid-week because a truck was late.
PAR levels matter most for high-cost and high-volume items. Ribeye priced wrong or ordered late costs you far more than an extra bag of flour. That difference in consequence is why experienced operators do not treat every SKU the same when setting PARs.
For more on how PAR levels connect to inventory forecasting and purchasing, see R365’s inventory forecasting guide and end-to-end procurement guide for restaurants.
Calculating PAR levels for a restaurant involves five steps:
| Item | Avg. weekly usage | Safety stock (15%) | PAR level |
|---|---|---|---|
| Chicken breast | 30 lbs | 4.5 lbs | 35 lbs |
| Romaine lettuce | 20 cases | 3 cases | 23 cases |
| Vodka (750 ml) | 8 bottles | 1.2 bottles | 10 bottles |
For liquor and wine, the same math applies, but shelf life is less of a concern. The bigger risk is capital sitting on shelves. Sweet Cow, working with Restaurant365, performs weekly counts of key items and monitors burn rates to reduce exactly that problem: money tied up in product that is not moving fast enough.
Repeat this process for every item you stock. Yes, that is tedious. It is also why most operators eventually move from spreadsheets to software.
For more on how to apply this calculation across bar programs specifically, see R365’s ultimate bar inventory management guide and how to set up PAR levels and reorder alerts with suppliers.
A spreadsheet can calculate a PAR level. What it cannot do is automatically update that number when your sales mix shifts, flag a vendor who just raised prices by 12%, or generate a purchase order at 6 a.m. before your morning manager arrives.
Several restaurant management system platforms address parts of this problem. Restaurant365 addresses all of it in one place. We are the only platform to natively unify restaurant accounting, inventory, workforce, payroll, and intelligence in one system, which means your inventory data does not live in a silo disconnected from your P&L or your labor costs.
That looks like this in practice:
Restaurant365 integrates with 100+ POS systems (Toast, Aloha, Oracle MICROS, Square, PAR Brink, Clover, and others) to pull sales data automatically, so usage calculations reflect what actually sold, not what someone remembered to write down.
Actual vs. theoretical (AvT) tracking compares what your recipes say you should have used against what your counts show you did use. The gap between those two numbers is where your money goes.
Par Review reports compare your set PAR levels against average daily usage, so you can see which items need adjustment before waste or shortages show up.
Contract pricing alerts notify you in real time when a vendor invoice does not match your agreed price.
Bushfire Kitchen automated more than 80% of invoice processing within weeks of implementing vendor integrations. Their CEO, Oliver Barwin, described one specific catch: “We’ve had alerts flag things like a $10,000 overcharge on a single beef invoice. Without that, it might never have been caught.” The company estimates $100,000 in annual savings through renegotiated supplier agreements, plus tens of thousands more from caught pricing errors.
Restaurant365 holds a 4.6/5 rating on G2, with 95% “Ease of Doing Business With” and 92% “Likelihood to Recommend” scores. We were a Leader in 39 G2 categories and ranked #1 in 12 of them (G2 Fall 2023 Grid Report).
One observation: most competing tools handle either inventory tracking or accounting, but not both in a single database. That split forces operators to reconcile numbers between systems, which is where errors creep in and where time disappears.

The Suggested Ordering report in Restaurant365 uses a specific formula to calculate what you need to order:
Ending inventory + accounts payable +/- transfers − sold quantity = on hand
On hand − PAR = suggested order
When the result is negative, you need to order. The system generates a suggested purchase order you can review, adjust, and send to your vendor. This removes the guesswork from reordering and reduces the chance that a busy manager forgets to place an order until it is too late.
Real results from operators who have adopted this approach:
Black Rock Coffee Bar (160 locations) shifted from monthly to weekly inventory counts after implementing Restaurant365, giving stores immediate visibility into actual vs. theoretical usage. New locations now complete full opening inventory before their first sale and join the weekly count cadence immediately. Kluzak, who led the rollout, said: “We decided to go with a weekly cadence to really give us the true information that we needed so that we could be proactive, week over week, instead of again waiting till the end of the month to figure out what was missing or where we overspent.”
Mitchell Management (Jimmy John’s franchisee) saved 96 hours and cut food costs by 2 points using EDI invoice automation and sheet-to-shelf counting. Managers count directly on phones and tablets, which reduced missed items and rework. Mitchell put it plainly: “I’m working with it every single day, and I’m like, why don’t I have this for Jimmy John’s?”
Kona Grill recouped its ROI in 3 months. One location achieved a 4.2% reduction in COGS; the company-wide average was 1.5% per store, translating to a profit increase of $15,833 per location. Michelle Caraig, Accountant at Kona Grill, said: “With Restaurant365, we have complete visibility of theoretical quantities of inventory on-hand and inventory used. Through the use of Hot Counts and Inventory Count Variance Reports we now have excellent control of our inventory.”

Not every item deserves the same attention. A controversial opinion: most restaurants spend too much time counting low-cost items and not enough time analyzing the 15 or 20 SKUs that actually drive their food cost.
That is where the 80/20 rule applies. In inventory management, the 80/20 rule (also called ABC analysis) states that roughly 80% of your inventory cost comes from about 20% of your items. Your proteins, specialty cheeses, and premium liquor are almost certainly in that top 20%. Set tighter PARs and count those items more frequently. The bottom 80% of items (dry goods, paper products, commodity spices) can tolerate looser PARs and less frequent review.
Practical tips for setting and maintaining PARs:
Review PARs monthly at minimum, weekly if your menu changes seasonally or you run frequent specials. Restaurant365’s guide to par levels and reorder alerts walks through setting this cadence with suppliers.
Account for vendor lead times. If your seafood supplier needs 3 days’ notice, your PAR for fish must cover those 3 days plus your safety stock.
Set different PARs by day of week if your volume swings significantly between Tuesday and Saturday. A single weekly average can leave you short on your busiest night.
Use recipe-level data rather than raw ingredient counts alone. Eli’s Restaurant Group used AvT analysis reviewed weekly with location managers and discovered one location was consistently overusing cheese and cream in mac and cheese. That kind of insight only comes from tying recipes to actual usage.
What is the 30/30/30/10 rule for restaurants? This rule suggests allocating your revenue roughly as: 30% to food costs, 30% to labor costs, 30% to overhead, and 10% to profit. It is a general benchmark, not a law. PAR levels directly affect the food cost portion: tighter PARs reduce waste and over-ordering, which keeps that 30% target within reach.
What are the ranks in a restaurant? The typical hierarchy runs from owner/operator to general manager, kitchen manager/executive chef, sous chef, line cooks, prep cooks, and front-of-house staff. For inventory purposes, the kitchen manager or general manager usually owns PAR level setting and counts, while the executive chef or owner approves vendor relationships and pricing. Defining this ownership clearly matters. Inventory problems multiply fast when nobody specific is accountable.

Ultra Steak (23 locations) used inventory cost-tracking tools and real-time data analysis within Restaurant365 to save $58,000 on ribs and $48,000 on lettuce. Those are not small rounding errors. That is $106,000 recovered from two line items.
Maru Hospitality Group used purchases-by-vendor and purchases-by-item reports to cut food costs, reduced their vendor count by 10%, and negotiated contract pricing. They also reduced ribeye waste by over 1,000 pounds (about $10,000 in sales) between 2018 and 2019 by switching to vacuum-sealed product, a decision informed by the data Restaurant365 surfaced.
California Fish Grill (50+ locations) made AvT tracking part of their operating culture. Paul Potvin described the shift: “When you start seeing something trending, where suddenly everybody’s showing that they’re growing in a product or they’re short and we’re wasting a product, it starts a conversation.” That kind of cross-location pattern recognition is nearly impossible with spreadsheets.
David Selby, a restaurant operator featured on the Restaurant365 podcast, reduced inventory carry costs by about 24% over the past year through PAR level work and reorganization. He also shaved his inventory counting process from 6-7 hours per person down to about 4 hours. That is roughly 2.5 hours back per count, per person.
As of July 2026, Restaurant365 serves 40,000+ restaurant locations. Our AI engine delivers an average 5% reduction in food costs, up to $100K in reduced labor costs, and a 15% improvement in forecasting accuracy. Those numbers are specific to R365 AI capabilities and verified as of July 2026.

PAR levels are arithmetic. The hard part is doing the arithmetic consistently, across every item and every location, week after week. Spreadsheets work until they don’t, and they stop working right around the time you open your third location or your food cost creeps up and nobody can explain why.
We connect your POS data, your vendor invoices, your recipes, and your counts into a single system that calculates what you need, tells you what to order, and flags problems before they become expensive. Operators like Black Rock Coffee Bar, Kona Grill, and Ultra Steak have put real numbers behind those claims.
