“I was managing 14 units with spreadsheets, paper checks, and frantic WhatsApp messages. With SudStay, rent arrives in my bank automatically on the 1st of every month without me sending a single text.”

Multi-Family Owner · 14 Units
“The Client Admin architecture in Profile 5 is genius. I own 85 units across 6 buildings. I invited two property managers, assigned their buildings in 20 seconds, and now I just watch the cash flow graphs update.”
Sarah Rosenthal
Portfolio Investor · 85 Units
“As a tenant, paying rent takes literally 10 seconds via Apple Pay. When our dishwasher broke, I uploaded a 5-second video, and the repairman was at our door the next morning. 10/10 experience.”

Frequently Asked Questions
How does automated rent collection and settlement work?
Tenants can link their bank account via instant ACH debit, debit card, credit card, or Apple Pay. When rent is paid, funds settle directly into the landlord's verified banking account. SudStay automatically marks the payment as settled on the ledger and issues digital receipts.
What is the difference between an Autonomous Landlord and a Client Admin?
Autonomous Landlords (Profiles 1–4) manage their properties directly. Profile 5 (Client Admin) is designed for owners who delegate operations: they can create multiple organizations, invite Property Managers via email, and assign specific buildings to each manager so PMs only see their assigned units.
Is tenant and financial data secure?
Yes. All government identifiers, tax information, and banking tokens are encrypted with military-grade AES-256-GCM ciphertexts. Our database runs in an isolated AWS private subnet with zero direct internet access, protected by automated backups and strict authorization middleware.
Can I invite existing tenants with ongoing leases?
Absolutely. You can import existing leases, set the current term end date, upload existing PDF agreements, and invite your tenants via email. They'll skip unnecessary steps and go straight to their payment dashboard.
How does the real-time chat work?
During the rental application process, SudStay spins up an isolated real-time room powered by WebSocket Socket.io. Both you and the applicant can message, share clarification questions, and view updates in real time without leaking private personal phone numbers.
