Karbon and Brevitax — workflow collaboration vs IRS delivery

Karbon publicly describes workflow and collaboration for accounting firms — email triage, work queues, templates, and visibility across client jobs. Brevitax describes the resolution engagement with IRS evidence, financial intake, and defensible deliverables on one case record.

How Karbon describes itself

Marketing focuses on how accounting teams coordinate work: shared inboxes, recurring job templates, client timelines, and partner visibility into who is doing what — reducing reliance on ad hoc email for firm operations.

What Brevitax adds for relief engagements

When the client job is IRS collection or controversy, workflow visibility alone does not parse account transcripts, produce Discovery, or defend implementation fees.

  • Parsed IRS ledger facts — CSED inputs, enforcement signals, filing posture
  • Form 433 financial qualification with tier discipline — economics vs ledger truth
  • Discovery, Strategy, and Work Verification PDFs co-branded to the firm
  • Implementation attestation and refresh against account transcript on verification
  • Brevitax Pro is $79/mo per seat with unlimited cases, for tax professionals only.

Typical firm motion

Accounting firms adding resolution revenue often keep Karbon (or similar) for general client work and adopt Brevitax for relief matters — especially when Discovery becomes a billed phase or franchise standard.
