What customers say

We have come to appreciate the high level of personal attention we receive from all our contacts at NOTICENINJA. They're always quick to address our issues, and the solutions are accurate, clear, and highly detailed. Thanks for everything the team does for TriNet Payroll Tax!

Bryce Thompson, FPCSr. Pricing & Tax Systems Analyst, TriNet

To have a partner like NOTICENINJA during tax filing time — providing good order, discipline, and services that filled a gap until we were back online with our other systems — was really invaluable. I can't say enough about the team.

FAQ

Frequently Asked Questions

Does NOTICENINJA automatically route and assign notices? +
Yes. NOTICENINJA automates assignment with a rule-based system that handles multiple-level rules and directs each notice to the right stakeholder by entity, branch, or jurisdiction — so nothing is misdirected or lost.
Can it report on notice activity and exposure? +
Yes. Customizable dashboards and reporting give leaders a clear view of notice volume, resolution status, and potential exposure. You can see where notices originate and the time and cost per jurisdiction — so you can address root causes and manage workloads.
Can you help us clear an existing backlog? +
Yes. Backlogs create a cycle — unaddressed notices trigger duplicate and sequential notices that compound the problem. NOTICENINJA helps close out your backlog and stay backlog-free, with automated workflows, due-date tracking, and document management that let teams resolve notices within 30 days.
Can NOTICENINJA track agency contacts? +
Yes. A dedicated module manages every agency contact and the related details — addresses, links, and login information — easing change-management challenges. Teams can add notes on specific jurisdictions and contacts to speed up resolution.
