Descriptions tell your client exactly what parts you have used for a service. In the days of handwritten workorders, clients tried to decipher the codes, much like we try to decipher the words in a prescription.
With the advent of computer generated workorders, your clients will appreciate your professionalism - and the clear statement of part names. While this may not seem to be a serious issue, in actual practice we often hear comments about precise workorders, and how impressed clients are with the new system that a shop has installed.
Do not use abbreviations when entering a description of a part. Is a DRSP a Down Rolling Siphon Pan or a Dayco-Romy Spark Plug? Abbreviations will get you in trouble. Use the full words - you have space for 30 characters. We really haven't seen parts that need more room.
Be consistent with your descriptions, because your lookups are done in alphabetical order. The Oil Filt. and Oil Filter will not group together. Nor will Spirk Plug and Spark Plog. They will be close, but separate. These are similar descriptions, but some will have a much greater distance on the look up scroll, or report, and may be overlooked. If you don't find the actual part you need, you may buy additional items, and your shelf stock becomes a liability - wasting both space and investment capital.
Manufacturer
The system does provide for the tracking of parts by manufacturer. To alleviate the need for spelling the name repeatedly, common supplier's names have been added to a lookup list.
You may press the 
key to access the name, highlight it, and press the Enter key to return the value to the field. If you type in a name, the system will verify it's accuracy, and display the pop-up list if you make an error.
Type Code
Inventory can be broken into subgroups for reports, based on the Sort Code. Although the computer does not any special format, or set codes, it is suggested that you use codes which make sense in your operations. While LUB may be significant to group lubrication items for one shop, others may wish to use a different code. It is best to use three letter codes to provide for the widest range of options.
