Which jobs are most overdue?

Save time

SJT reduces time and stress spent on paperwork.

Saved time can be used to produce the end result customers pay for.

For example, if you spent 70 minutes per day on paperwork before, SJT could reduce it to 10 minutes.

60 minutes saved
x 20 days
x 12 months
= 240 hours.

Thats 30 days saved per year
(30 x 8 hours).

Re-investing the saved time into actual work at £12 per hour would equal £2,880/year.
