System is evolving!
Right now, there is no Job # or job table.
Just a simple customer table tied to a rate table which has an effective and discontinued date for the rates (may be multiple start/end combinations which skip no calendar dates) used to apply toward billings - by work accomplished date lookup.
Thinking of adding a job # table related to each customer.
Now I wonder if rates s/b locked into the job table rather than (OR in addition to) using a dated rate table as before. Not sure if we would need to change rates DURING the duration of a 'long" ongoing job? Some jobs are BID while most are T and M.
Got a great design related answer last time. Wonder what may be suggested for me this time - maybe something I have not yet even considered ?
