The finance brain

Meet Aria.
Your CFO that runs the money.

Aria is the half of OBI that runs your finances — end to end. It invoices, collects, books, pays, reconciles, and forecasts, then briefs you every morning. Not reports you have to read and act on. The work, already done.

Aria, OBI's finance brain — a glowing golden character with an 'A' seal, standing on an executive desk over a city skyline
Who is Aria
Aria is what you'd get if you could hire a world-class CFO — one who sees every dollar in and out — and have them work your books, chase your cash, and plan your runway around the clock.
The money engine

Money in, money out — handled.

Aria closes the full loop of a business's cash. It bills the work, collects what's owed, reconciles every account to the penny, and projects what's coming — continuously, without you touching a spreadsheet.

01

Bill

Aria creates and sends invoices and quotes through Gmail or Outlook, and tracks every one from billed to paid.

02

Collect

Overdue accounts get automatic follow-up campaigns, payment plans, and arrangements — until the money lands.

03

Reconcile

Bank statements are recomputed and matched to the penny, with anomalies flagged and a certified audit trail.

04

Forecast

Forward cash, liquidity, and multi-year projections — so you always know what's coming before it arrives.

Every movement is marked on a live dashboard — paid, pending, overdue, collection rate — and rolled into a morning brief that lands in your inbox before you start the day.

What Aria runs

One brain. Your entire back office.

Aria doesn't do one finance task well — it replaces the stack of tools a growing business stitches together, and runs them as one connected system.

Invoices & quotes

Create, send, and track invoices and quotes — with billed, paid, pending, and average-invoice KPIs live.

Collections & plans

Debtor alerts, follow-up campaigns, collection loops, and payment arrangements that run themselves.

Appointments

Books and syncs meetings across Google Calendar and Outlook Calendar — and coordinates against your day.

Bills & vendors

Accounts payable, a vendor hub with spend and health, and 1099 tracking with W-9 and threshold watch.

Statements

Bank statement intelligence — reconciled to the penny, certified, with a live working session you can query.

Treasury & forecast

Forward cash, liquidity, a payment calendar, and multi-year forecasts with scenarios and an executive brief.

Where Aria goes deep

Not a dashboard. A finance department.

Behind the KPIs, Aria runs the heavy machinery a real finance team would — treasury, reconciliation, and forecasting — at CFO depth.

World-class Treasury

Aria watches your liquidity across time horizons and projects your forward cash before it happens.

  • Total cash, expected in, and scheduled out at a glance
  • Forward-cash curve for the next 45 days
  • Payment calendar that flags projected shortfalls
  • A treasurer's read on demand

Statement Intelligence

Drop in a bank statement and Aria recomputes every running balance and matches it to the penny.

  • Every row read, none illegible, fully certified
  • Anomaly and fee detection with flagged signals
  • A live Statement Canvas you can question in session
  • Reconciles against your OBI records

Forecast & Studio

Build multi-year projections from your real data — with honest, declared assumptions, not black-box math.

  • 5-year revenue, P&L, cash flow, and balance sheet
  • Moderate, upside, and downside scenarios
  • Transparent disclosures on every assumption
  • Financial Studio: upload a model, Aria reads and fixes it
Beyond the numbers
Aria doesn't just crunch the money — it thinks about your business. It scores every client, spots the next best move, and briefs you like a partner, not a printout.
Connected to your tools

Aria works where you already work.

No new inbox, no new calendar to learn. Aria plugs into the tools you use and acts through them.

Email

Gmail & Outlook

Sends invoices, replies to clients, and leaves drafts ready for your review.

Calendar

Google & Outlook

Books appointments and coordinates against your live calendar across both.

Files

Drive & Sheets

Reads and writes to Google Drive and Google Sheets, so your data stays where it lives.

Inbox

Morning Brief

Delivers a daily brief on your cash and accounts straight to your email.

The architecture

One memory with Lumi.

Aria isn't a bolt-on finance tool. It shares a single operational memory with Lumi — the Operating Graph — so the money and the work are always in sync.

Shared memory

One brain, two engines

Aria runs the money and Lumi creates the work from the same source of truth — nothing falls between tools.

Certified math

Reconciled to the penny

Every balance is recomputed and certified, so the numbers Aria acts on are the numbers you can trust.

Executive brief

CFO-level output

Aria rolls reconciliation, liquidity, and action items into an Executive Financial Brief — declared assumptions and all.

You run the vision. Aria runs the money.

Give your business a CFO that never sleeps — billing, collecting, reconciling, and forecasting while you build.
