What we do

1065 & K-1 Generator. Upload your books (P&L and Balance) and partner sheet; we produce a ready-to-review Form 1065 and K-1s. You choose your tier:

  • Bronze — Development only (use the generator to produce PDFs).
  • Silver — Development + Filing (we file your 1065 & K-1s).
  • Gold — Preprocessing + Development + Filing (we also prepare input spreadsheets).

AI Assistant. A chat experience (post-login) for quick briefs, assignment drafting, and workflow routing. Built to save time on recurring finance ops.

How it works

  1. Upload inputs — P&L, Balance, and Partners (CSV/XLSX).
  2. Set return options — line G/H flags (initial/final/amended; cash/accrual) and year/period.
  3. Generate — Create the 1065 and K-1 PDFs; review allocations, capital analysis, and liabilities.
  4. File — If on Silver/Gold, we handle filing; otherwise, you can download and file yourself.

We right-align numbers, normalize percents (e.g., 0.5, 50, 50%), and support 2 → 100+ partners.

Who it’s for

  • Funds and partnerships generating multiple K-1s annually.
  • Finance teams seeking consistent output and fewer manual edits.
  • Operators who want an AI helper for notes, assignments, and quick checks.

Trust, privacy, and security

  • Auth & Data — Firebase Auth; Firestore for structured records (partners, books, return options).
  • PDF generation — Overlay onto IRS fillable PDFs using a deterministic coordinate map.
  • Storage — PDFs stored in object storage; access via time-limited signed links.
  • Privacy — We minimize data retention and log access to generated files.
