Domuso + Fortress OS
Resident payments through Domuso post to the ledger in Fortress OS, with no import file and no double entry.
Updated · 3 min read

What is the Domuso + Fortress OS integration?
Domuso handles resident payments. Fortress OS connects to it per property using a Domuso code, and payments taken through Domuso post against the resident's ledger in Fortress. Your team keys nothing twice, and the ledger stays current without an overnight import.
Key takeaways
Each property is mapped with its own Domuso code, so payments land at the right site.
Payments post against the resident ledger without an import file.
Your ledger and your payment processor agree without a month-end cleanup.
How does Domuso work with Fortress OS?
You connect Domuso in Integrations Setup and give each property its Domuso code. That code is how a payment taken at one site finds the right property in Fortress. Once you set it, resident payments flow through to the ledger without anybody exporting a file or keying a batch.
What data flows between the two?
Payments move from Domuso into Fortress and post against the resident's ledger, so the transaction lands on the account it belongs to. Your team sees the same payment history the resident sees, which is the version they will ask about on the phone.
Who handles the setup?
Our integrations team handles documentation exchange, API keys, and end-to-end testing. Most Domuso connections go live in a few weeks. You can request a setup any time.
Why should you connect Domuso to Fortress OS?
A payment processor that does not talk to your ledger leaves a gap somebody closes by hand at month end, under time pressure. When payments post as they happen, your on-site team can answer the awkward question about whether rent arrived.
What changes once you connect Domuso?
Same payments tool. Different day-to-day for your team.
| Daily task | Without the integration | With Fortress OS + Domuso |
|---|---|---|
| Recording a resident payment | You export from the processor, import to the ledger, then fix what did not match. | The payment posts to the resident ledger on its own. |
| Answering a rent question on the phone | You check the processor, then the ledger, then apologize. | Your team opens the resident ledger and reads the answer. |
| Month-end close | Someone reconciles the processor against the ledger line by line. | The two already agree. |
| Adding a new property | You set the site up twice and hope the mapping holds. | You enter the property's Domuso code once in Integrations Setup. |

Frequently asked questions
Quick answers about how Domuso and Fortress OS work together. Don't see your question? Ask us →
How is a property connected to Domuso?
In Integrations Setup you enter the property's Domuso code. That code maps the site in Domuso to the property in Fortress, so payments post to the right ledger.
Do payments still need to be entered in Fortress?
No. That is the point of the connection. Payments taken through Domuso post against the resident's ledger without your team keying them again.
Can we use Domuso at some properties and not others?
Yes. You configure the connection per property, so a portfolio can run Domuso at the sites that need it and something else everywhere else.
Do we still need a Domuso account?
Yes. You keep your own Domuso relationship and pricing. The connection between Domuso and Fortress is part of Fortress OS.
