Watch it work

A quick overview of RentFlow OS.
A look at the key features.

Why rental owners love it

No double-bookings

Availability and maintenance overlaps are flagged before you confirm a job, so you never promise a unit twice.

Deposits under control

Track collected, outstanding and held deposits by booking, and see customer balances at a glance.

Know your best assets

Compare revenue, utilization and contribution per unit so you keep and grow what actually earns.

Yours, offline & private

Runs in your browser with no account and no subscription. Records stay on your device; back up to dated JSON anytime.

Equipment rental management questions

What rental businesses can use RentFlow OS?

It is designed for equipment, tool, event and party rental workflows rather than residential property or tenant management.

What can I manage?

Manage rental assets, bookings, availability, customers, deposits, returns, condition checks, maintenance and asset profitability.

Does RentFlow require a subscription?

No. It is a one-time download that runs offline in a current browser and stores records locally.
