β‘ Quick Summary
Last month a client asked me what had been approved on his apartment in March. The information existed. Most of it was in his Digital Vault, which at that point was a Google Drive folder. The rest was in a WhatsApp thread, an email, and a PDF I had named badly. It took me 35 minutes to answer a question that should have taken ten seconds.
That was my filing, not his.
If you own here and someone else holds your keys, that question is a test you can run yourself. Pick a past month, ask what was approved, and time the answer. Thirty-five minutes is not a good number.
What a folder cannot do
A shared drive is a static archive. Files sit in it. A contract has no memory of the CapEx it triggered or the invoice it produced three months later, so the linkage between them lives in one place only, which is my head.
Retrieval is by filename. Which means the quality of the record equals my naming discipline on a Tuesday afternoon between two site visits. That is a fragile thing to ask an owner to depend on.
And a folder has no live position. It has documents about a position. The difference sounds academic until someone asks what has been spent this year and the honest answer is "give me until this evening."
The concept was right. Drive was simply the first version of it.
What changes with the new platform
Iβm excited to announce that the Vault now runs on PropOS. Every update, invoice, quotation and site report attaches to the asset itself rather than to a folder structure someone has to remember to maintain. Three things change in practice.
Greek documents arrive readable, with the original retained. Contractor quotations, technical notices and insurance renewals come in Greek. Previously they reached the owner as my paraphrase in an email. Now the readable version and the source sit together, so nothing depends on my summary six months later.
The conversation, the decision and the invoice are one object. The Asset Risk that prompted a repair, the approval, and the Technical Project Management record of the work are linked, permanently, against the property. Not three platforms and two languages.
Screenshots from the PropOS public demo environment. All names, addresses and figures shown are demo data.

The record survives me. If I am on a roof in Pangrati and you need to know what the plumber quoted in April, you can simply open it yourself.
The same logic applies to a reserve raised at a delivery inspection: it is worth exactly what it can still prove three years later.

A disclosure
I am a founding design partner of PropOS, the platform underneath the Vault. I hold no equity and no ownership in it. The arrangement is a referral one, nothing more. I am putting that in the body of the article rather than in a footnote, because a footnote is not where anyone weighs it.
The honest limit
Let me be direct. Changing supplier does not make a decision better. A poor CapEx call recorded perfectly is still a poor call. What it changes is retrievability: the decision stays findable, in your language, after everyone involved has forgotten the details.
That is a narrower claim than most software makes. It is also the one I can stand behind, which is why it is the only one I am making here.
Current clients will see their Vault links in this month's reporting cycle. For everyone else, this is now the standard baseline for how we manage assets in Athens.
