Good Item Numbers will Make Your Life Much Easier!

Item numbers are used to uniquely identify items that you carry in inventory. Some companies will call them “part numbers”, “model numbers”, “product codes”, etc... and you can change the name “item number” to whatever you want (we’ll describe how later in the guide) By whatever name, item numbers are important for you, and the systems you use. If you or your system can’t uniquely identify an item, you can’t effectively account for it’s activity and whereabouts within your inventory. Item numbers also serve as a shorthand for longer item descriptions. Instead of entering an entire name or description for an item, you can use a much shorter item number.
This speeds up the process of data entry and inventory management.

Big companies often use long and complicated numbers for their item numbers. These are fine if you're operating a complex warehouse or retail operation. If this makes sense for your operation, then you probably already have a numbering scheme and don't need to read much further. But if you want to create a system that's easier to work with and uses your own item numbers, here are some of our recommendations.

Item Numbering Schemes

NOTE: Clearly Inventory has a feature called “Quick Entry” that allows you to enter your current inventory levels, item descriptions, units of measures, locations, and costs on an item by item basis. This feature also has an “Auto Item Numbering” option which will create item numbers for you. If you plan on using this feature (i.e. if you do not plan on uploading your data into clearly inventory via spreadsheets or tables) you do not need to worry about a part numbering scheme. Examples of the “Quick Entry” part numbering schemes are on the following page.


Tips on Creating Item Number Schemes

DO NOT use a manufacturer's serial number or part number for your part number. These numbers are often too long and cryptic. Plus, if you switch suppliers, or the manufacturer changes their number it becomes meaningless to your organization.
Keep item numbers short - but not so short that they could be mistaken for other numbers (i.e. quantities). 4 - 8 characters will suffice for most organizations.
Do not load item numbers with meaning - do not try to use the item number to describe your product. This will only make your numbers longer, and more complicated. Save this information for the item description.
Consider using a few letters. Letters will help further distinguish your item numbers from other numbers, and they will greatly increase the number of possible item numbers you can have while keeping the overall item number length as short as possible.
Using a few letters from the beginning of your item description at the beginning of your part numbers will make it much easier to look up items in pick lists. For example, if you were creating an item number for “Sauce, Chocolate” you might create the number “SAU101” , “Sauce, Caramel” “SAU102” etc...
Avoid loading inventory item descriptions with more information than absolutely necessary. Information such as vendor names, manufacturer, country of origin, expiration dates, and so on belongs in the "item details", or" transaction details", areas where it can be used more effectively.
Do not use characters that might confuse people or software. For example, using a comma in your item number might make it look like a quantity or price. Using a "/" can result in Excel formatting your part number as a date. Symbols such as "<", ">", and "*" can have unintended consequences when moving data between Clearly Inventory and your spreadsheet program. Try to keep your item numbers simple and alpha-numeric where possible.

Clearly Inventory offers two “auto numbering” schemes that you can use if you enter your item quantities via the “Quick Entry” feature. One method that we call “Auto Alpha Numeric” will take the first three letters of the description and then add a 3 digit number to the end making a 6 character number. The other method called “Auto Number” will generate a number starting with 1001 and increasing by 1 for every subsequent item.

Here are examples of the two auto-number schemes that Clearly Inventory uses.

Once you decide on a numbering scheme, create another spreadsheet with your item descriptions and their associated part numbers. Now you should have two spreadsheets or tables. One with your Locations and another with your item descriptions and item numbers. Next we’ll create units of measure.
