The results are compared against the company's warehouse records. Auditors can use these counts as part of observing inventory, but only after judging how reliable the process is. The drone replaces some physical scanning, not the auditor's own evidence.
Physical inventory observation has long been one of the most labor-intensive audit procedures. PCAOB AS 2510 and ISA 501 generally require auditors to attend the physical count when inventory is material and attendance is practicable. They observe the count process, make test counts and consider cutoff and condition. Computer vision changes how the count is taken. In warehouses, autonomous drones or vehicle-mounted cameras move along aisles, and vision models decode barcodes, read text labels, and classify each location as occupied or empty. Vendors such as Gather AI and Corvus Robotics sell drone systems for this kind of scanning. Software then reconciles each scan with the warehouse management system and lists matches, mismatches, missing pallets and unexpected ones. Outdoors, photogrammetry or LiDAR builds a 3D surface of piles of coal, grain, aggregate or wood chips and calculates volume against a base surface. Several large audit firms have publicly described trying drones for inventory observation. For the auditor, the key question is whose evidence it is. A drone count run by the company is management's count, so the auditor evaluates the count procedures and the controls over the data, and still performs independent test counts. A tool run by the auditor produces audit evidence whose reliability the firm must establish. Several misconceptions persist. A scanned pallet label identifies the SKU but does not prove how many units are in the shrink-wrapped pallet. Images rarely show obsolescence, damage or whether goods on hand are held on consignment and owned by someone else. A stockpile volume is not a quantity until a density assumption turns it into tons, and that assumption can move the result more than any imaging error.
An indoor drone flies the high rack aisles of a distribution center at night, scans pallet barcodes, and flags locations where the warehouse management system shows stock but the image shows an empty slot.
At a quarry, a drone survey produces a 3D model of aggregate stockpiles. Software calculates volume, which is converted to tons using a bulk density that a specialist tested.
A car dealer group uses drone imagery and plate or VIN recognition to count vehicles on large outdoor lots, then compares the list with its floor-plan financing records.
During a year-end observation, the auditor picks locations from the drone exception report and from the inventory records and counts them by hand. This tests both the drone's output and the records.
Warehouse drone scanning is in commercial use at some logistics operators, and continuous cycle counting could reduce reliance on a single year-end count if the controls over the process are strong. Auditors may increasingly design procedures around testing those systems, while still making independent counts. Limits remain. Vision systems see labels and surfaces, not what is inside cartons, what condition goods are in, or who owns them. Regulations, site safety and battery life also constrain deployment. Expect adoption to grow where rack heights and SKU counts make manual counting expensive, rather than everywhere.

Un recuento realizado por la empresa es un proceso de gestión. El auditor evalúa los procedimientos y controles y realiza recuentos de prueba, como ocurre con cualquier recuento de clientes.
La etiqueta identifica el artículo y la ubicación. La cantidad dentro de un palé envuelto no es visible en la etiqueta.
El volumen se convierte en cantidad sólo después de multiplicarlo por la densidad, que cambia con la humedad y la compactación. Es por eso que la densidad la suele comprobar un especialista.
AS 2510 (PCAOB) e ISA 501 cubren los requisitos de observación de inventario.
La conciliación con el sistema de gestión de almacenes requiere hacer coincidir cada lectura con una ID de ubicación. Sin posicionamiento, una lectura no se puede comparar con el registro.
