Serialized inventory software for businesses

Businesses that keep serialized products in stock: electronics resellers and repair shops, equipment rental companies, field service teams, and distributors of tools, machines or medical devices. It is stock management software for a company, not a tool for consumers to check a device they own.

Turn on serial tracking for the products that need it. When a delivery arrives, scan or type each unit's serial number to add it to stock, then scan it again at each sale, transfer, return or repair. Every event is stored against that one unit, so your team can always see where it is and what happened to it.

Yes. Serial tracking is included on StockFlow's free Starter plan for small businesses: per-unit serials, scanning from a phone, and each unit's full stock history, with no credit card needed.

StockFlow supports both from the same web and mobile platform: serial numbers for individual units and batch or lot numbers for interchangeable stock, on the same product when needed. Barcode and QR scanning work from a phone or handheld scanner on both the web app and the mobile app, so a warehouse or shop floor is not tied to a desktop.

In inventory management, serial number tracking means a business records the unique serial of every unit it stocks, rather than only counting products per SKU or batch. Each unit can then be traced through receiving, storage, sale, and any return or repair, giving the business a complete history for that exact item.

Serial number tracking gives every single unit its own unique identity, useful when each unit needs individual history (electronics, equipment, medical devices). Batch tracking groups units made or received together under one shared lot number, useful when units are interchangeable (food, cosmetics, chemicals). See batch and lot tracking for that approach.

Yes, and for medical devices, electronics and batteries it is common. The lot number groups the units from one production run so a recall can find all of them in one search; the serial number identifies each unit so you know which customer has it. StockFlow lets you record both on the same product.

Electronics manufacturers and retailers use it for warranty claims and counterfeit prevention. Medical device companies use it for regulatory traceability and recalls. Equipment rental and field service businesses use it to track individual asset history, maintenance, and location.

When one of your customers makes a warranty claim, scanning the serial number of a unit you sold shows the purchase date, original order, and whether the unit is still within its warranty window — eliminating manual lookups and reducing fraudulent claims on units bought elsewhere or outside the warranty period.

It helps. Each unit you received is registered once in your own stock, so a unit returned to you with a serial that is not in your records, or that is already marked as sold, is flagged as a likely counterfeit or duplicate. It only checks your own records, not a manufacturer database.

If a defect is found in a specific batch of units, serial number tracking lets you search for the exact serial numbers affected and pull up every customer or location that received one — turning a recall into a precise, auditable list instead of a blanket notice to all customers.

A barcode or QR scanner speeds up the process significantly and reduces data entry errors, but it isn't strictly required — serial numbers can be entered manually on receiving and sale. Most businesses scanning at any volume use a phone camera or handheld scanner paired with barcode scanning software.
