Rentsync + Fortress OS
Syndicate listings to the major rental portals and track the leads, from one marketing platform.
Updated · 3 min read
What is the Rentsync + Fortress OS integration?
Rentsync is a rental marketing platform built for multifamily. It combines a website content management system with listing syndication, pushing your availability out to internet listing services like Apartments.com, Zillow and Facebook Marketplace, then tracking the leads that come back.
Key takeaways
Listing automation distributes availability to the major portals without manual posting.
A content management system runs your property websites alongside the syndication.
Lead automation and reporting show which portal produced the lease.
How does Rentsync work with Fortress OS?
Fortress OS sits underneath your stack as the operating layer. When something changes in Rentsync, Fortress picks it up and pushes it to the other systems that care. No double entry. No end-of-month reconciling. No spreadsheets stitching things together.
What data flows between the two?
The exact fields depend on the marketing/ils use case. The goal is simple: both systems show the same truth. Records, statuses, and key events stay in sync. Your team is not the human glue between them.
Who handles the setup?
Our integrations team handles documentation exchange, API keys, and end-to-end testing. Most Rentsync connections go live in a few weeks. You can request a setup any time.
Why should you connect Rentsync to Fortress OS?
Posting the same vacancy to six portals by hand is how listings drift out of date, one portal at a time. Syndication publishes once and keeps every copy consistent, and the reporting tells you which of those six portals is worth paying for next year.
What changes once you connect Rentsync?
Same marketing/ils tool. Different day-to-day for your team.
| Daily task | Without the integration | With Fortress OS + Rentsync |
|---|---|---|
| Keeping records in sync | Copy-paste between tabs, hope you got the numbers right. | Records match across both systems on their own. |
| End-of-month reconciling | Spreadsheet exports, manual cleanup, late nights. | Numbers already line up. Close the month, go home. |
| Onboarding new properties | Manual setup in Rentsync and every other system. | Fortress provisions the connection so new sites pick it up. |
| Answering “what’s the truth?” | Open three tabs, compare, guess which one is current. | One source of truth, kept fresh by Fortress. |
