About Cynsio

Built from the practice of renting out property

Renting out property has become mostly admin. Cynsio does the number work that comes back every month. The decisions stay with you.

Where Cynsio comes from

Cynsio is built from the practice of renting out and managing property. Anyone who rents out property knows how much of that work is retyping. The same amount goes from the bank statement into a spreadsheet, from the spreadsheet into a letter, and from the letter into the owner statement.

That work follows the same pattern every month. That is why it belongs in software, not in your evenings.

Every single month:

  • Matching rent against bank statements
  • Working out indexations and drafting the letter
  • Figuring out per owner what came in
Where the name comes from

Cijns is the old Flemish word for the recurring due paid on land and property. Whoever collected it kept a cijnsboek: who paid, when, how much.

Cynsio is that ledger, minus the handwriting.

How we work

Three choices you will see in Cynsio

  • Cynsio prepares, you decide

    Cynsio matches every payment to the right rent and prepares indexations and letters. Applying and sending is up to you, when you choose.

  • Everything starts from the same data

    Properties, leases, tenants and owners live in one place. Payments, indexations and owner statements build on them, without you retyping anything.

  • We only promise what works

    What this site describes, Cynsio does today. What is still in development, we call exactly that.
