Narration transcript
Lakeview Software, a fictional company, needs its 2026 Form 1120. Here is a Jiber filing agent, start to finish.
Step one. A simulated outbound call confirms the engagement.
Step two. The agent drafts an upload request for WhatsApp or email. It is held, not sent.
Step three. It extracts figures from the W-2s, the 1099, last year's return and the trial balance.
Step four. It flags a salaries mismatch and a missing depreciation schedule, and asks the client.
Step five. The return is drafted line by line, to JSON and CSV.
Step six. Automatic tie-outs for the preparer. A human signs off.
Step seven. A sandbox e-file with a mock acknowledgment. Nothing reaches the IRS.
