The goal

Property managers in the Gulf juggle units, cheques and owners in many files. Aqar keeps the portfolio, the tenants, the contracts and the money in one place, with the cheque life of the region built in.

What it shows

Portfolio: Properties and units with size, rent and status, and an occupancy board.
Leases: Rent schedules from 1 to 12 cheques a year, deposits, renewal in one click.
Cheques: Not deposited, deposited, cleared, bounced or replaced; a cleared cheque writes the invoice and the payment.
Money: Rent invoices with VAT, partial payments, tenant ledger and ageing.
Owners: Ownership shares, management fee and monthly owner statements.
Care: Maintenance requests, documents with expiry warnings, reports with CSV.

Security controls

Control	What it stops
Roles (viewer is read-only)	Changes by owners or auditors who should only look.
Prepared statements (PDO)	SQL injection.
CSRF token on every form	Actions sent from another site.
Login throttling and one-time passwords	Password guessing and shared passwords.
Audit log of every change	Money changes that nobody can explain later.

Try it yourself

# PHP 8.1+ with pdo_sqlite (or MySQL). No framework, no Composer, no build step.
php -S 127.0.0.1:8080          # or upload the folder to any PHP hosting
# open http://127.0.0.1:8080/install.php → SQLite or MySQL → the first admin account
php seed.php                    # optional: demo data with users for every role

What I learned

Local reality matters: post-dated cheques are the centre of the money flow here.
An automatic step (cheque cleared → invoice and payment) removes most mistakes.
Owners trust a monthly statement more than any dashboard.
