Private preview

What's in Rentium today

Rentium already runs real rental portfolios in production. Self-service access is not open yet — here is what is working in private preview.

Your portfolio, structured

LLCs, properties, units, tenants, and leases — the real shape of a rental business, not a flat list of addresses.

Rent charges post themselves

Monthly rent posts automatically per active lease, with partial first and last months prorated by days.

Payments and rent roll

Record checks and Zelle payments as they arrive; the rent roll shows live balances and who's behind, with overpayments held as credit.

A ledger you can trust

Every charge and payment lands in a balanced double-entry ledger with a per-lease statement — posted entries are never edited, and corrections stay explicit.

Built for teams

Workspaces and member access out of the box, with tenant isolation enforced in the database itself.

Import by uploading what you have

Drop spreadsheets, CSVs, lease PDFs, or screenshots into the built-in assistant. It proposes an import plan, waits for your confirmation, then creates and verifies the records.

Use the AI that fits the job

Rentium's built-in assistant makes importing your existing data as simple as attaching files. When you want to work from another AI, connect the same workspace securely to ChatGPT or Claude — no API keys or MCP expertise required.
