This product saved my life on a 40+ client deliverable deadline for Q3 quarterly estimates. I am able to track all my tax advisory clients in one place to ensure they are all on track for their current year tax liability.
This changes my practice to proactive, helps clients avoid underpayment penalties and interest, and creates long-term happy clients. Most importantly, it's fast. While professional tax software will let you estimate quarterlies, it is super slow for too precise information.
I can get an 85% correct answer, in 80% less time, all while tracking all clients in a centralized location.
