Property management software
One system to run
your properties.
Celsus helps owners and operators track properties, collect rent, manage leases, handle maintenance, and report on the portfolio without spreadsheets doing the real work.
Free up to 5 properties and 25 units. No card required. Control and Insights include 14-day trials.
The problem
Too many property teams still run on handoffs.
When payment tracking, lease records, maintenance requests, and reporting all live in different tools, you lose time, cash, and trust.
The platform
One platform.
Daily operating clarity.
Celsus connects the records your team actually depends on so owners, managers, and operators stop working from partial information.
Leases and renters
Keep every lease in one record.
Manage renters, leases, and supporting documents without rebuilding the history every time a question comes up.
Plans
Start free. Upgrade when the work gets heavier.
Choose Core to get the operating basics in place. Move up when billing complexity, reporting depth, or portfolio scale demands it.
Core workflows
The operating layer your team uses every day.
Celsus replaces fragmented admin work with connected workflows your team can actually use every day.
Leases and renters
Keep every lease
in one record.
Manage renters, leases, and supporting documents from move-in to move-out instead of rebuilding the story every time a question comes up.
Payments
Collect, reconcile,
and follow up faster.
Record rent, issue invoices, handle deposits, review payment proofs, and keep arrears visible before they become month-end surprises.
Maintenance
Track repairs with
accountability.
Work orders, vendors, and supporting files stay tied to the operating record so teams can see what was requested, assigned, approved, and closed.
Reporting
Know what needs
attention next.
Move from raw activity to dashboards, exports, forecasting, and delinquency signals so reporting becomes a live operating tool instead of a retrospective cleanup exercise.
Trust and fit
What matters before you commit.
Know what matters before you commit: can you trust the record, will it fit your team, and where do the AI boundaries sit?
01
Append-only audit record
Ledger and audit events are recorded with timestamps so teams can trace what happened and when.
02
Role and entitlement controls
Access is shaped by system roles, custom roles on paid plans, and plan entitlements instead of one shared permission model.
03
Payment workflows built for reality
Celsus supports invoicing, deposits, refunds, offline proof review, and bank-transfer operations as plans expand.
04
Integrations and scale paths
API keys, webhook support, storage add-ons, and enterprise limits give teams room to grow without replacing the system.
Ready to start
Start on Core while the work is still simple.
Get properties, leases, rent tracking, documents, and the audit record in place before the portfolio gets heavier.
Trust
Built for operators
who need proof.
Clear records, clear access boundaries, and workflows that match real property operations make the system easier to trust under pressure.
Who it's for
Pick the operating model
that matches your team.
Celsus fits owners who need visibility, managers who need day-to-day execution, and enterprise teams that need governed scale.
Daily execution
Run the daily work from one operating system.
Leases, invoices, maintenance, documents, and payment follow-up live in the same workflow instead of across chats and spreadsheets.
What changes for this team
01
Manage leases, renters, payments, and proofs from one workflow
02
Track maintenance work orders, vendors, and response policies
03
Keep documents and audit history attached to the operating record
AI and intelligence
Use intelligence where it helps,
with clear boundaries.
Use forecasting, narrated exports, and governed AI access without guessing what is included or where the boundaries are.
How signup works
Know what happens after you click start.
The signup flow keeps the selected plan path with you, so setup starts in the right place instead of making you choose again.
