The running cost of agents, and the quiet admin changes

What we're tracking

• •The margin bill behind agent features When a vendor adds AI agents to its product, something changes in the economics that a buyer rarely sees. Traditional software has very low marginal cost: once it is built, serving one more customer costs almost nothing. Agents break that pattern. Every time an agent runs, it consumes compute, and that compute is a real, recurring expense the vendor pays whether or not the customer notices. The industry has started calling this the margin bill for agents — the gap between what AI features cost to run and what customers currently pay for them.
• •Agents inside the software delivery workflow The second strand of the agent story is about where the work happens. GitHub published a walkthrough of using agents to carry a feature through the stages of building software — described as four agent apps that "can help you scope, secure, roll out, and ship a feature across the SDLC–all without leaving GitHub" [2]. The phrase that matters there is "without leaving." The appeal of putting agents inside the tool a team already uses is that nobody has to switch context, copy work between systems, or reconcile two sources of truth.
• •What "built with agents" looks like from the inside It is useful to see how the vendors themselves build with this technology, because it tells you how mature their claims really are. Klaviyo's co-founder spoke at an industry event about exactly this. By his account, he "came to SaaStr AI to walk through how a 2,300-person public company builds AI products" [3] — and the framing was explicitly about the build system rather than the vision.
• •A compliance change that hits the bottom line directly Not every important change is about AI. Xero flagged a regulatory shift for Australian businesses: "From 1 October 2026, Australian businesses will no longer be able to add a surcharge to eftpos, Visa, Amex or Mastercard payments" [4]. This is a small, concrete rule with a direct effect on margins for any business that currently passes card fees on to customers. Those fees do not disappear; they simply stop being something you can add at the till.
• •Moving data between systems without losing it The last item is the kind of improvement that gets little attention and saves a great deal of frustration. Google announced that it is "introducing two key improvements in Google Sheets that preserve formatting and linked data when converting files from Microsoft Excel" [5]. The reason this matters is that most businesses do not live inside one vendor's world. Files move between spreadsheet programs constantly, and every conversion is a chance to lose formatting, break a formula, or quietly corrupt a figure.
• •The through-line for a buyer Four of today's five items point the same way. Agents are no longer a demo; they are a standing cost inside the products you buy, a question of who pays and when. The other two — a surcharge rule and a cleaner file conversion — are reminders that the unglamorous parts of a tool, compliance timing and data portability, often decide whether it is worth keeping. Choosing software well means weighing both at once, which is the habit we keep returning to in choose software worth using.
