Every software line item on an architecture practice’s P&L answers the same quiet question: does the hour it buys back cost less than the hour it bills out? PAZ Academy has just put a price tag on that question. The PAZ-BOX suite — eight Archicad Add-Ons under one floating licence — opens at CHF 574/year for the Premium tier and CHF 974/year for Business, with an Enterprise tier priced bespoke. I am the franc those invoices clear in, and I can tell you exactly where this one pools.

←TODAY: CHF 574/year for a floating licence, set against an architect billed out at CHF 120+/hr — the arithmetic settles inside the first week of saved rework.
→3012: By the Zurich-3012 horizon, the practice that survives is the one whose tooling earns back its own capex on a line you can read, not a promise you have to trust.
Fulcrum: A tool is only cheap when you can see the number where it pays for itself — and PAZ-BOX is unusual in that it shows you that number out loud.

Where the money actually goes

The signal here is not “new plugins exist.” It is the licensing shape. A floating licence — one concurrent seat shared across the team — is a deliberate piece of unit economics. It means a six-person studio does not pay six times; it pays once and queues. For a small Swiss or German office that runs Archicad 28/29 across Windows and Mac, that converts a per-head cost into a per-office cost, and the total cost of ownership drops accordingly. The 50% student discount is the same instinct pointed at the funnel’s top: price low where the lifetime value is long.

Look at what each tool actually buys back. Per PAZ’s own product notes, the Fassadengenerator turns façade edits from “full remodelling cycles” into “parameter changes” — a project architect quoted on the page calls the win “consistency: everyone gets the same façade logic.” Raumstempelfix aligns hundreds of room stamps in a batch instead of one drag at a time. Volumenstudie compresses a massing study from hours to minutes. None of these is glamorous. All of them drain billable hours that currently leak out of the late-project crunch — the most expensive hours a practice owns, because they arrive when the deadline removes your pricing power.

The tier that changes the unit, not the price

One line item breaks the pattern. PAZGPT — chat-and-voice control of the Archicad model, built on GDL-aware automation — sits only at Enterprise. Every other PAZ-BOX tool has a “does-X-faster” value proposition that prices cleanly per saved hour. PAZGPT has a “changes-how-you-work” proposition, and PAZ has priced it as such: bespoke, not per-seat. That is a vendor signalling where it believes its durable margin lives. Read the runway, not the round — the franc remembers which platforms could show their earn-back and which called nine years of feature-burn “traction.”

Atelier: Before you commit the practice to any tool this quarter — PAZ-BOX included — open a spreadsheet and put the licence cost on one line and the hours it buys back on the next. If the second line does not clearly clear the first inside a year, the tool is a subscription, not an investment, no matter how good the demo felt.

Hack: This Hack teaches you to price any tool by its payback, not its sticker. The medium is one SQL query; the domain is Databases. Drop your candidate add-ons into a table — annual cost, hours saved per week, your billing rate — and let the query rank them by the fraction of a year it takes each to pay for itself. Anything under 1.0 earns its capex back inside twelve months; the smaller the number, the faster the franc returns.

SELECT tool,
       chf_per_year,
       ROUND(chf_per_year
             / (hours_saved_per_week * 46 * 120.0), 3)  -- 46 working weeks, CHF 120/hr
         AS payback_fraction
FROM addons
ORDER BY payback_fraction;          -- < 1.0 = pays for itself this year

Feed it Premium at CHF 574 against even one hour saved per week and the payback fraction lands near 0.10 — the licence clears in roughly five working weeks. That is the number a vendor’s marketing rarely prints and the only one that should move your decision. You can build the same logic straight into Archicad via the PAZ Archicad Add-Ons page, where the full tier breakdown lives.

The move

Run the query against your own rates before the next licence-renewal cycle. PAZ is hosting a PAZ-BOX walk-through session; bring your real billing rate and your worst late-project bottleneck, and make the suite prove its payback fraction to your face. Do not buy on the demo — buy on the number that says how it earns itself back, and if a tool will not show you that number, that absence is the number.
