Everything the big systems do
Leases, CAM, accounting, budgets, work orders and portals. Built for commercial property, not apartments.
Without the big-system feel
Clear screens a person can read on a phone at night. No consultants, no six-month rollout.
From what you already have
QuickBooks files, spreadsheets, lease PDFs and photos of invoices. Useful on the first afternoon.
Start from the files you already keep.
Drop in your QuickBooks export, the rent roll spreadsheet, lease PDFs, bank files and photos of invoices. You preview every record, duplicates are caught, and the whole batch can be undone in one step.

A true-up every tenant can follow.
The year-end reconciliation runs every lease's rules: share, base year, caps, exclusions, gross-up and admin fee. Each expense line is traced to its invoice and to the lease clause that allows it, and anything questionable is flagged with its evidence before a statement goes out.

See next year coming, and the loan behind it.
Budgets start from last year's actuals and every lease's rent steps, renewals and recoveries. The forecast shows a range, not a guess, and lists what drives it. Loans are watched for maturity, coverage and the gap a refinance would leave.

One product, two kinds of desk.
Your books stay yours.
Commercial leases and ledgers are sensitive. Here is exactly how we protect them, in plain words, including what we haven't done yet.
Your data, walled off
Every record carries your organization's id, and the database itself refuses rows that aren't yours (row-level security on every table).
Encrypted
Encrypted in transit between you and us, and at rest in the database and file storage. Files open through short-lived signed links.
People approve
Nothing is sent, posted, filed or paid without a person. Every change lands in an audit trail with a name and a time.
AI that doesn't learn from you
The AI providers we use do not train their models on your data. They get only what a task needs.
Help us draw the first set.
We are opening the product to a small group of owners and firms first. You get a guided import with our team and a direct line to the people building it. Pricing isn't set yet; we'll talk it through with you before you pay anything.
