Tally helps store teams keep shelves stocked and shoppers happy.
Let technology handle the busywork
Tally autonomously scans every aisle, capturing the data your team needs to keep shelves full and priced right. Instead of searching for problems, teams quickly resolve surfaced issues and focus instead on delivering exceptional shopping experiences.
Every aisle covered. Every detail captured.
From standard shelves to fresh areas, bunkers, and high top stock, Tally captures it all—no aisle or fixture left behind. Working together, Tally RFID tracks soft goods while Tally Spot provides precise insights for targeted areas.
See your shelves with unmatched accuracy
Powered by Simbe Vision™, Tally identifies products and shelf conditions with unmatched accuracy, even capturing smaller or recessed items with high fidelity. From promotion errors to misplaced products, Tally reveals what others miss, giving a complete picture of the store.
Get insights that drive action
Tally transforms shelf data into real-time, actionable insights. Associates receive prioritized task lists in the Simbe Mobile App, while managers and executives get reports, dashboards, and high-resolution images to guide strategic decisions.
Tally delivers real-time store intelligence powered by computer vision, AI, and automation.
A friendly face
Tally’s approachable, compact design fits seamlessly into busy store environments, moving thoughtfully around shoppers and associates to enhance the in-store experience. Store teams are more productive and satisfied—and happier shoppers spend more time and money—when Tally is in the aisle.
Best-in-class optical system
Tally’s ultra–high-resolution imaging, autofocus, and expanded camera suite capture sharper, richer visuals across every shelf. Enhanced 3D depth and 360° fisheye cameras extend visibility into areas such as upper steel, bunkers, and recessed shelves—zones that would otherwise be challenging to monitor. As well as enable digital twin capabilities for expanded storewide walk-throughs.
Extended runtime
Now, with up to 12 hours of operation plus shorter and faster charging cycles, Tally covers more of the store, more often. Its night-scan capability enables continuous visibility even after hours.
Top-tier computing platform
Powered by NVIDIA edge technology, Tally processes shelf data in real time, turning scans into actionable insights faster than ever. Its advanced AI engine delivers responsive intelligence with significantly reduced latency.
Enterprise-proven performance
Trusted by leading retailers across continents, Tally delivers measurable impact at chain-wide scale. Its modular platform easily integrates advances in vision, compute, and power continuously evolving to meet the needs of modern retail.

Inventory Scanning Robot FAQs
An inventory robot autonomously navigates store aisles, scans shelves using sensors and AI, and detects out-of-stocks, pricing errors, and misplaced products in real time. Tally, Simbe's autonomous shelf-scanning robot, captures shelf conditions multiple times per day and delivers prioritized action lists to store teams via its mobile app and digital or printed reports. The result is faster issue resolution, more accurate inventory, and increased store associates focus on customers.
Shelf-scanning robots combine cameras, depth sensors, and AI image recognition to capture and analyze every product on the shelf. The robot navigates autonomously through store aisles, photographs each shelf section, and flags out-of-stocks, low-stock items, misplaced products, and pricing errors. Results are delivered to the cloud and prioritized task lists are generated within minutes. Tally also supports RFID scanning for item-level tracking.
Yes. Inventory robots automate cycle counting by continuously scanning shelves throughout the day, replacing manual section-by-section counts with always-on coverage. Tally scans every aisle multiple times per day using image recognition and optional RFID, delivering up-to-date inventory data without dedicated labor hours. Retailers working with Simbe have reallocated up to 50 hours per store per week to customer-facing work.
Most retailers deploy inventory robots through a Robotics-as-a-Service (RaaS) subscription that bundles hardware, software, maintenance, and analytics into a single recurring fee. Pricing varies based on store count, store size, scanning frequency, and selected capabilities. Simbe's RaaS model eliminates upfront capital expense and aligns cost with delivered value. Retailers can estimate their potential return using Simbe's ROI calculator or request a custom quote.
Deploying an inventory robot in a store typically happens in one day, including mapping the store, integrating with existing inventory and pricing systems, and onboarding the store team. Chainwide rollouts scale quickly from there, with timelines driven by store count and IT integration scope. Ongoing maintenance includes routine sensor wipes and docking for charging. Country Supplier moved from a 3-store pilot to full 55-store deployment in under four months.
