The computer software for Job Shops and manufacturers can significantly ease the complication and expense of operations, and varying ranges of solutions are available. For example, you can invest in a sophisticated CAD (Computer Aided Design) system to produce and process two- and three-dimensional models, or just go with an application that allows you to read CAD files produced by your customers. Other applications include financial (payroll, accounts payable, accounts receivable, general ledger) and operational (workflow management, bill of materials, purchasing).
