Access can be used to construct a database to what you want. At my place of work, we use a database developed in house, that tracks exactly what you want.
Reports are generated weekly of items due for cal/maintenance for the next x days. The generated work sheets are scanned and saved in PDF format , and are linked to the item that was serviced, cal reports are saved in as well, as well as any other information required, like purchase orders for parts and maintenance manuals.
Once the job is completed, the next due date is added, and the old job archived. All cal reports, or maintenance records can be retrieved at any time. New cal/maintenance tags can also be generated/printed.
All you need, is some one to code the database for you.
