The purpose of muster roll is to mark the attendance and record keeping if you can maintain the records of attendance and salary through software you need not go for traditional record keeping just be sure that you can rely on your software for the data. you can always take a print out and submit it to officials with your office seal and signature. Being on safer side you can also ask your software provider to mention muster roll on top of the report page.
