I will start by asking you a few questions.
1. Since it is a needle punch, you can use duplicate printing, but this can not be done in a single printout of the attribution of the various couplets, of course, we can take a second printout or marked with a stamp to solve the problem. If we give up duplex printing, is it a one-time print out of four couplets and then cut or each time you print you need to put in four separate sheets of paper. In addition, whether to allow the option to print a specified number of couplets individually.
2. Is the bill of sale filled out independently or extracted from the sales ledger? Either way, you should have an indexed list of items to avoid entering invalid data and also to improve efficiency.
3. Custodians, reviewers need to be authenticated, that is, EXCEL files can be authenticated to the operator.
These are just some of the many questions, and the reward points have nothing to do, if I design and prepare this form, I will find more and more uncertainty, so I recommend that you complete your own, for the time being can not be solved independently of the problem can be asked at any time.
