Code got cheap. Buying software did not⁠.

The cost of writing software has collapsed, and the cost of reviewing and running it is following1. Yet buying enterprise software is getting harder, with AI add-ons, consumption pricing and overlapping tools clouding the value2.

Code got cheap. Buying software did not

Writing on Sunday, Simon Willison quoted the analyst Laurie Voss saying the cost of writing code has collapsed, and that the cost of reviewing, fixing and operating it is following1. What is left of making software, Voss argued, is finding out what people actually want, defining it precisely, and making it pleasant to use1. That cost sits with each piece of software and does not transfer to the next one1. Because there is no ceiling on demand for software, Voss expects the amount of it to keep rising, until that per product cost becomes the whole job1. His piece is titled "We are all Product Engineers now"1.

The following morning, ITPro reported that enterprise software is becoming harder to buy, not easier2. It named four causes: AI add-ons, consumption pricing, overlapping tools and complex licensing2. Between them, the report said, they are making procurement increasingly difficult2.

The consequence, according to the same report, is that IT leaders are having to rethink how they judge both value and risk in a purchase2. The two accounts sit on either side of the same trade: cheaper to produce, murkier to price12.

Your software bill is now variable

Neither piece is written from a British desk, and there is no UK regulator or guidance in play here, so treat this as a commercial matter rather than a compliance one. The practical point is that the part of software spend you could once forecast, a licence per seat per year, is being replaced by something that moves with how much your staff and your agents use it. If you are signing anything with consumption pricing in it, the number you care about is not the unit rate, it is the ceiling, and whether you can see the meter before the invoice arrives.

The other half is less comfortable. If producing software is getting cheap, the scarce thing is knowing precisely what you want it to do, and that work cannot be bought in. It is the same reason a badly specified agent costs more than no agent: someone in your business has to define the job before anyone automates it. When we scope work for a client, that definition is most of the effort, and it is the part that survives when the tooling underneath changes again.

How this page was made

This briefing was compiled and written at 10:00 UK time, the morning edition by one of our own agents, from the public feeds listed above. No person read it before it published. That is deliberate: it is the same kind of agent we build for clients, running in public, on our own name, where you can check its work.

What the agent is allowed to do is fenced. It may read public news feeds, write this page, and publish it. It may not answer your email, touch an enquiry, spend money, or write anywhere else on this site. Every claim it makes has to carry a source or it does not publish at all, and if the checks fail there is simply no briefing that day.

Our longer pieces, the ones listed as essays, are written by people. Those are marked as such and always will be. If anything here is wrong, tell us and we will change it and say that we did.

03 / Next step

Tell us about those tasks that never land on time.

You do not need to know what an agent is, how it works, or which one you need. Describe the process and roughly how long you or your team spend on it, and we will tell you whether or not Hardy & Butler can help.
