Calculating the ROI of Restaurant Inventory Systems

A Guide for Multi-Unit Operators

Every restaurant operator needs a clear path to managing inventory, recipes, and costs. While basic tools like spreadsheets can do some of the work, specialized inventory systems are much more effective.

Specialized systems can reduce costs by 2–3%. For a restaurant location generating $1 million in annual sales, a 2% reduction translates to $20,000 in annual savings per location. Here is how you can calculate and realize the ROI of modern inventory software.

1. The Administrative ROI: Reclaiming Labor Costs

Automated Invoice Processing: Automated invoice processing saves managers and the accounts payable (AP) team time while increasing accuracy. There is no manual recording or mailing invoices for managers, and the AP team will not need to enter or code expenses for invoices. Automated invoice processing can save managers 1 or 2 hours per week, and accounting teams 2–5 hours per restaurant per month.

Receiving Audit Service: Specialized services provided by your software provider, like COGS-Well’s Receiving Audit Service, eliminate the need for manual inventory item maintenance by your team. New items are added and reviewed by our audit team immediately on receipt. This service can save managers or system administrators 1–2 hours per week per location.

“COGS-Well’s invoice scanning and audit service saves each of our managers 2 hours per week. It is also saving us 4 hours per week at the home office.” — Billy Williams, IT Manager, Collier Restaurants 

Faster Inventory Counts: Transitioning from spreadsheets to a dedicated system like COGS-Well for inventory counts is faster and more accurate. Items and costs are always up to date, and managers can count by storage location using a tablet. For managers counting using a spreadsheet or antiquated system, 2 to 3 hours per count session can be saved.

Systemized Transfers: Systemizing inventory transfers between locations or a commissary eliminates the need for phone calls and manual tracking. Once fulfilled, managers feel confident that adjustments are automatically made to item costs and quantities for each location.

“Our managers like the transfer feature in COGS-Well. They like that they can make requests to the commissary and review fulfillments via COGS-Well.” — Jennifer Posner, Controller, Bambuza Vietnam Kitchens & Bars Accounting Integration 

Accounting Integration: For financial teams, the ability to automatically export inventory valuations and transfer adjustments directly to a General Ledger (GL) is a game-changer. It eliminates the risk of manual data entry errors and ensures reporting is timely across your entire fleet.

“Our old inventory system did not have a General Ledger export, so the ending inventory adjustments were entered manually. Due to the COGS-Well export to NetSuite, we save an hour per week, our reporting is timelier, and our accuracy is improved." — Linda Liu, Director of Finance and Accounting, Impact Kitchen

2. Tighter Controls that Reduce Your COGS

As mentioned earlier, inventory control systems have been proven to reduce a restaurant’s cost of goods sold (COGS) by 2–3%. This reduction is largely the result of tighter controls.

“The last inventory system we were on was antiquated, and as a fleet, our COGS were higher. Now, we’re running somewhere around 3% lower.” — Jeremy Lanni, Supply Chain Coordinator, &Pizza

Purchasing Controls & Cost Alerts: Automated systems allow you to better control purchasing by tracking the history for every vendor, invoice, and item. Most systems will also provide Cost Alerts when prices change by a certain percentage, so you can react quickly. They also track Cost Trends so you can see what is coming or evaluate different vendors.

Increased Count Frequency: Automating the process often results in more frequent counts. High-price or high-volume items can be counted more often, providing visibility that naturally reduces waste, giveaways, over-portioning, and theft.

“Our managers are taking inventory counts every two weeks. We export the adjustments to our NetSuite General Ledger shortly after that and generate bi-weekly operating Profit and Loss statements for each location.” — Rich Ortiz, Director of Finance, Buzz Hospitality, dba Ri Ra Group

Suggested Ordering: An automated ordering process controls what items can be ordered from which vendors. It can suggest the right quantity to order based on on-hand inventory, Par levels, and projected usage. More accurate ordering results in reduced spoilage and better consistency.

“Our waste number significantly decreased as a whole because we were able to tackle our waste with the suggested ordering feature in COGS-Well. We're talking thousands of dollars every period.” — Emir Ayden, Director of Operations, Impact Kitchen

3. Strategic Insights: Beyond the Basics

To truly maximize ROI, you can implement two concepts that are only practical with automation and POS integration:

• Theoretical vs. Actual (TvA): Theoretical costs and usage represent what your costs and usage should have been based on your recipes and sales mix. Comparing them to your Actual costs and usage isolates variances, allowing you to pinpoint exactly where you are losing money.

• Menu Engineering: This analyzes popularity versus profitability. Items that are high-profit, but low-popularity, are often referred to as Challenges. Identifying these allows you to adjust your menu or marketing strategy to drive higher overall profits.

“We strongly believe that tracking theoretical costs is essential... The added insight into food cost in real-time is critical.” — Noah Kopito, Director of Kitchen Operations, All Parts Considered (Mamahuhu)

"With COGS-Well’s menu analytics tools comes the power of making better decisions about our menu. We had no way of getting at this data before." — Jennifer Beougher, CFO at Ruby Slipper Restaurants

4. Enhanced Multi-Location Management

If you operate multiple locations, making sure inventory and recipe items are up to date manually is almost impossible. A system like COGS-Well makes this much easier, even when every location is not identical.

Reporting and comparing performance across locations makes finding problem areas—and opportunities for improvement—much easier.

“We use COGS-Well to manage multiple bar and restaurant concepts. It is easy to set up, manage, and report on the restaurants in each concept and to evaluate the performance for the entire concept.” — Chris Carvalho, Director of accounting, Palisades Hospitality Group

ROI Benchmarks: What COGS-Well Customers Achieve

On average, COGS-Well’s multi-unit operators report:

• Labor Efficiency: 2+ hours saved per week for restaurant managers; 2+ hours per month saved for accounting teams.

• Bottom Line Impact: A 2–3% reduction in COGS per restaurant.

• Operational Precision: Significant improvements in data accuracy.

• Strategic Growth: Better tools for managing multiple locations at scale.

For the modern multi-unit operator, the cost of an inventory system is a fraction of the value it returns. By automating the manual grind and providing the visibility to manage by the numbers, you turn a system into one of your most profitable assets.
