Chapter 01 — Artificial intelligence

A co-pilot that never sleeps.

Keysy's AI is not a gadget bolted onto the tool: it is embedded in every workflow, from the indexation letter to the bank reconciliation.

i.

It reads your documents

Drop a lease, an invoice, a diagnostic report: clauses, amounts, deadlines and obligations are extracted, classified and linked to the right property — no manual entry.

ii.

It detects before you do

Emerging unpaid rents, overdue works SLAs, forgotten indexations, expiring leases: every drift is identified and quantified before it becomes a problem.

iii.

It prepares the action

Every alert comes with its response ready: graduated reminder, regulatory letter, work order. You validate in one click — or let it run.

Chapter 02 — Platform

A management firm, in your browser.

Residential building facade

Residential

Apartment blocks, individual units, furnished rentals — tenancy agreements managed with precision, from rent receipts to inventories.

Modern office building
pl. ii

Offices

3/6/9 commercial leases, ILAT indexation, service charge refactoring — tertiary rigour without the spreadsheet.

Retail shop front
pl. iii

Retail

Ground-floor units and retail — ILC indexation, rent ceiling removal, tenant works schedules tracked to the day.

Logistics warehouse
pl. iv

Industrial & logistics

Warehouses and business premises — derogatory leases, ICPE obligations, documented preventive maintenance.

The full cycle, covered.

Our principle: augment first, automate second. Every workflow is detected and prepared by the AI; execution stays under your control for as long as you wish.

Chapter 03 — Compliance

Obligations, treated as a core subject.

2026 reform

E-invoicing native — not bolted on.

Where legacy tools rush to graft a module, Keysy was built for the reform: every receipt and every invoice is born compliant.

  • Factur-X & UBL native formats — EN 16931 standard
  • Compliant invoices ready for transmission via an accredited PDP
  • Lifecycle tracked from issuance to collection
  • Automatic e-reporting to the tax authority

Rent capping compliance

Caps verified at every reletting and every indexation, including rent-controlled zones. No inadvertent overrun.

iii.

Tax & declarations

Consolidated property income, documents gathered, export ready for your accountant. The declaration becomes a formality.
