Product Availability

Products are produced in production quantities. Our system monitors OEM sales and anticipates consumption levels. So we can usually ship from stock. Although we manufacture a majority of our product’s constituent parts and have good control over the supply line, a rare “out of stock” situation could develop, delaying shipments several weeks. Uncommitted product inventories are subject to prior sale.

Shipments are made on Wednesdays.

Why So Many Invoices?

In many ways, Compac is organized like a fast food operation. Production and transaction processing occur in “real time”. That is, as sales occur, connected events also happen at the same time. This makes our operations quick and efficient which is why we ship within a day or two at bargain prices.

Our TaskMaster system handles everything on “an eye for eye, tooth for a tooth” basis. For instance, each purchased items has its own invoice. So, if you buy purchased item has its own invoice. So, if you buy ten different part numbers, you’ll get ten invoices, ten acknowledgements and ten packing lists. This may sound unusual but offers advantages when performing “real time” processing.

Here’s some things you should know about our system: Product part numbers are poised in our database ready for the next “real time” sale. Logical quantity and packaging combinations are part of the data record so packaging instructions, insurance and shipping charges are accessible to the system’s routines during the order booking episode. For example, a product may reside in the database in 50 or more combinations of quantity, shipping carton, number of cartons and carton weights. Add to this, value per carton, and the hundreds of combinations of shipping weights and zones and whether the shipment is ground or air. This all adds to the complexity of the iterations.

With the automatic “smart system” as our objective, processing data on an “eye for an eye, tooth for a tooth” basis has sever advantages. For instance, we automatically adjust inventory, update accounts receivable, prepare labels, and create the UPS shipping manifest as the sales event happens. This in turn, allows automation of related production, inspection and management functions which require “real time” data sources. Equally important, it simplifies the undoing of a transaction should become necessary.

Why Two Boxes?

Domestic shipping episodes are normally defined as single carton shipments. However, when content makes this impractical or when value generates a high insurance risk, the shipment may be divided and packaged in more than one carton.

System operations, damage susceptibility, value and count are factors governing the number of cartons used.

As previously mentioned, logical product sales are stored in our system as predefined potential shipping episodes. So when a particular order is entered into the system, everything about how it is to be packed and shipped is already known by the system. If multiple cartons are defined as the packing method for a particular product, that is how it will be packed.
