A whole book — from your availability page and your leases.
Nothing to migrate. No import template, no keying in. praeba reads the page you already keep current, then reads the leases you put through it, and the book is simply there.

A lease arrived overnight. Watch it read itself.
praeba asks. You confirm. Most mornings, that is the whole job.
Keep scrolling — the money is already current.
Nothing waits on memory.
Paid — and every figure that should move, moves.
Who is carrying what, one click deep.
Worked, kept, and sent on as a spreadsheet.

Third floor · 19 Leonard StreetThe three columns praeba writes — item, value, and the Excel formula behind each line. Kept against the property for this session; saving to your records lands in a later phase.
The recordkeeps itself up to date.
The screen the morning opens on.
What needs you, in order, oldest first — beside the fee tracker, the ledger of what the system did while you were away, and the year against its target. The morning above is this screen, worked.
The whole book, on one page.
Sq ft on the market, the status of every instruction, what is let and what is coming back. One measure, one mark — the colours mean a state, never a sector.
The dates diarise themselves.
Expiries, breaks and rent reviews come out of the lease as it is read, and land in praeba's own diary without anybody keying them in.
The board, and the money each stage carries.
Offer received, viewing, negotiating terms, in solicitors, awaiting signature — with where the fee sits and where the deals are, side by side.
Billed against the target, all year.
The pipeline with an offer in, what has actually been billed, and the fee on each deal modelled from the rents on your instructions — labelled a model until it is invoiced.
The invoice drafts itself at completion.
Aged debt, chase history and what has actually been paid — with the draft already written from the completion statement, waiting on your check.
Floor by floor, with the paper that proves it.
Each floor, its size, its terms and its state — beside the documents filed against the building and the timeline of what happened to it. The morning above worked this record; here it is, built.
Portfolio
The honesty rules the product obeys.
praeba does not keep your documents.
It reads the file, records what it learned and where it came from, then deletes its copy — whether the read succeeded or not.
It only ever sees what you point it at.
Connected storage is scoped to the files you choose, not your whole drive. Where a calendar is connected, praeba reads it and never writes to it.
Nothing is invented.
A figure praeba cannot source is left blank. A blank is a fact — a plausible guess would be a lie, and one lie makes the whole book worth re-checking by hand.
A modelled number says so.
Where praeba projects a fee rather than reading one, it is labelled a model on the screen and never banked as billed.
The book refreshes only if you say so.
Re-reading availability pages on a schedule is off until you switch it on, and a book that isn't enrolled is named in the log rather than quietly skipped.
Email a document in. It files itself. Live
Forward a lease to the address we give your firm — or point a mail rule at it once — and it is read and filed like any other door. praeba still watches no inbox: your firm is identified by the address the mail arrived at, never by who sent it.
Your book already exists. praeba switches it on.
The link builds the book. Your leases fill it in. There is nothing to migrate and nothing to key in twice.
Tell us where to look.
We’ll come back to you ourselves — praeba is taking a small number of founding firms, and every one of them starts with a conversation.
That’s with us.
We’ll come back to you ourselves, usually the same day. If you gave us your availability page, we’ll have read it before we call.
