SKU and item code standardization for electronics and spare parts inventory

Running an electronics store, warehouse for spares, or a repair shop can very soon become quite frustrating. As a result of having many capacitors, boards, phones' screens and chargers on stock, even minor differences in the item description will bring about huge chaos. Lack of any systematic approach leads to inefficient work of your engineers who cannot find what they need on time. The implementation of SKU and Item Code Standardization will make your life much easier by offering you a systematic approach that you can apply throughout your business.

‍Why electronics and spare parts businesses need SKU and item code standardization

Your electronics and spare parts require special considerations due to several aspects. Keeping track of a large number of tiny pieces that may look very similar whether this is 5V or 12V power regulators or display assemblies for iPhone 13 and iPhone 14 models may result in human errors in manual inventory management. You would not have a uniform system, and your employees would need to remember details or rely on confusing labels, which results in order fulfillment delays.

Another issue is duplicate products. If your receiving team finds it hard to locate your product in the software, they may simply decide to make a new item entry in the database. As a result, you end up with two records of the same smartphone battery in your system. You get phantom stockouts, extra orders and capital tied in your excessive inventory, Standardized codes will help you to find any item immediately.

Building a standard SKU and item code structure

A well-designed framework should have a logical system which will be easy for everyone on your team to interpret. An effective Stock Keeping Unit (SKU) is made up of important characteristics of the item encoded in alphanumeric form.

Prior to developing the structure, you may want to know the differences between SKUs and standard item codes.

SKU vs. Item code comparison

Feature	Stock Keeping Unit (SKU)	Item Code
Main Objective	Specific variant of the item for sales and inventory tracking.	Identification of raw materials, components, or catalog items.
Structure	Alphanumeric format with brand information, type, and specifications.	Usually consists of a numeric sequence or MPN.
Field of Application	Sales, POS, multichannel online shopping, and ERP.	Internal production, BOMs, and purchasing.
Flexibility	Designed based on an internal warehouse classification system.	Typically takes up the supplier or manufacturer numbering system.

Sample SKU formats for electronics and spare parts

Product Description	Category	Brand	Model / Spec	Variant	Sample Standardized SKU
Samsung S22 OLED Screen (Black)	Display (DIS)	Samsung (SAM)	S22 (S22)	Black (BLK)	DIS-SAM-S22-BLK
Dell 65W Laptop Charger	Adapter (ADP)	Dell (DEL)	65 Watt (65W)	Standard (STD)	ADP-DEL-65W-STD
100uF 16V Electrolytic Capacitor	Component (CMP)	Universal (UNI)	100uF (100U)	16 Volt (16V)	CMP-UNI-100U-16V
Logitech Wireless Mouse (Grey)	Peripheral (PER)	Logitech (LOG)	M330 (M330)	Grey (GRY)	PER-LOG-M330-GRY

Standardizing existing inventory records

In case the existing warehouse management software is already packed with inconsistent item descriptions, cleaning up this mess involves the following steps.

Step 1: Review your inventory records

Export the entire list of items in your ERP inventory software into an Excel file. Check for descriptions that are incomplete, missing part numbers, and inconsistent naming (such as "Sams.", "Samsung", and "SEC").

Step 2: Merge SKUs

Merge SKUs that contain duplicates by bringing together their physical inventory counts, updating your inventory tracking system, and removing duplicate items.

Step 3: Clean up your catalog using standard SKU naming format

Transform the clean-up version of your catalog according to the new standard SKU format. Item titles will need to be renamed using a consistent syntax such as: [Brand] + [Model] + [Category] + [Key Spec].

Step 4: Upload the New SKU List Into ERP or Inventory System

Upload the standardized SKU list in your ERP or inventory management system. Linking standardized SKUs to barcodes or QR codes will make the process much more efficient. Creating your own barcode inventory labels for your warehouse shelves and bins will greatly help in increasing the speed of stock counting and stock picking.

Maintaining a consistent SKU system as inventory grows

Establishing a good SKU system is not an end in itself but should be sustained over time through rigorous internal controls.

1. Establish rules of governance

Develop a straightforward standard operating procedure (SOP) when creating products. Limit access permissions to ensure that only authorized inventory managers create SKUs. This prevents employees from creating random SKUs when receiving inventory deliveries.

2. Manage discontinuation properly

If there is going to be a discontinuation of the spare parts, refrain from deleting it immediately. Mark the product as "Discontinued" or "Archived" in the inventory ERP system. It enables you to save the sales history for the particular item and not let the employees place orders for it.

3. Consistency among various locations

In case you operate a lot of retail stores, servicing centers, and distribution centers, ensure the consistency in SKU usage among all locations. It will enable you to transfer your inventory easily without the creation of duplicate SKUs in each location separately.

Conclusion

Stock tracking and management of electronics doesn't necessarily have to be accompanied by perpetual discrepancies and missing items. SKU and Item Code Standardization gives you full control over your warehouse inventory, ensuring that everything is accounted for from receipt to purchase. An organized code system with barcoding eliminates errors during picking, ensures duplicate purchase prevention, and improves efficiency and accuracy in general. Organizing your inventory management system now will give you a good basis for future business growth.

FAQs

1. What are the differences between an SKU and an item code?

SKU refers to unique codes that are used to track the specific variations of the products (such as size, color, or capacity) for sales and inventory management purposes. In turn, an item code or a part number refers to unique codes of raw materials or manufacturer's components used in the assembly process.

2. What data is needed in an SKU?

A perfect SKU must include data about the product that will assist in identification of a specific product through hierarchical arrangement of these elements (category, brand name, model number, technical characteristic, etc.). A good SKU must also be short and readable without any special characters.

3. Is it possible to standardize the existing inventory without changing all item codes?

Sure, you can continue using manufacturer's part numbers as additional fields within your ERP, whereas at the same time introduce standardized SKUs for managing your warehouse inventory.

4. Why are barcodes helpful when it comes to using standardized SKUs?

Barcodes refer to machine-readable images of alphanumeric SKUs that enable fast, reliable scanning of the products for receiving, picking, and stocktaking purposes.
