"It reads like our workpapers. First tool my staff trusted on day one - the close tied out in four minutes instead of a Friday afternoon."

How it works

The same shape you build in the app.

Every agent is four stages: Input, Variables, Steps, Output. CSV in, XLSX out - the exact rail you meet at sign-in.

InputCSV

Point it at your files

Drop the messy source - bank exports, GLs, payroll. Stored or per-run.

CSVtrial_balance.csv
Variables2 vars

Set what changes each run

Period, entity, tax basis - asked before every run, so one agent serves every close.

Steps3 steps

Build it, watch it transform live

Sketch each step in plain language. Every edit re-runs on a sample instantly - you see the data change as you build.

OutputXLSX

Ship it, keep the trail

A clean, footed file plus a full run record - every step, every tie-out - ready for sign-off.

Features

Built for people who foot their totals.

3.1

Build-time flow preview

A live miniature of your pipeline running on real rows while you edit. See exactly what each step does to your data before you ever hit run - so tuning never burns a run.

3.2

Reconciliation you can prove

Per-column tie-outs, variance flags, and a tolerance you set. Tied out is sage green; a variance is rose. The numbers carry the meaning, not decoration.

3.3

Review and sign-off, free

Reviewers and viewers never pay a seat. Builders trigger runs; reviewers verify and sign. Your whole firm sees the work without your whole firm being a line item.

Your data

Your files stay yours.

The finance audience reads sloppiness as risk. Here is exactly how your data is handled.

Data handling Encrypted
  • Encrypted in transit and at rest. Files travel over TLS and are stored encrypted, scoped to your account.
  • Your account, your scope.Every file path is bound to your user; no run can read another account's data.
  • Bounded execution. Steps run in a restricted sandbox with per-step time and row limits - no surprises, no runaway jobs.
  • A trail for every run. Inputs, every step, and every tie-out are recorded, so you can always show your work.
