The Machine Markdown

Software is taking over the markdown, discounting short-dated stock in New Zealand supermarkets. The always-moving price has barely arrived: shelf labels typically change about once a week.

What is it?

Software is taking over the markdown: in New Zealand, tools such as WhyWaste discount supermarket stock nearing expiry. The always-moving price has barely arrived, with shelf labels typically refreshed about once a week. Whether shoppers read software-set prices as fair stays unproven.

Why now?

Marking down short-dated stock used to be a manual judgement. In named New Zealand chains, software makes that call, and electronic shelf labels make any price quicker to change. The trust question is still open.

Who’s building it?

Markdown-software makers such as Upshop, selling into grocery chains, and the installers fitting the electronic shelf labels that carry the price.

01 · The market
Who’s in it
Builders — markdown-software makers selling expiry discounting into grocery chains.
Buyers — large retailers who can afford the tooling and the integration.
Gatekeepers — smaller retailers deciding whether to buy in or fall behind.
What’s at stake
Smaller retailers risk falling behind larger competitors who can afford markdown software built and run at real scale.
Whether continuous pricing reads as efficient or manipulative.
Whether software-set markdowns stay weekly or start moving by the hour.
What’s unsettled
Whether shoppers notice, or mind, prices moving on signals they never see.
Whether smaller retailers can afford to compete on the same signals.
Whether continuous pricing eventually needs the same disclosure rules as dynamic pricing elsewhere.
02 · How the demand matureda progression, not a timeline
Adoption
Grocery chains hand expiry markdowns to software in more than a quarter of one co-op’s stores.
Proof
Named store rollouts confirm the tools are in use, not just in a vendor’s pitch.
Continuity
Shelf prices still refresh on a set timetable, often weekly, rather than adjusting by the hour.
Scrutiny
Shoppers start noticing prices move on signals they can’t see, reaction still unproven.
03 · Where the market goesthe forks, not a prediction
→Trusted or gamed — software-set pricing either becomes an accepted retail norm, or shoppers start reading every price cut as manipulation.
→Smaller retailers may be priced out of the tooling that makes the biggest margin difference.
→Disclosure rules built for dynamic pricing elsewhere could extend to markdown algorithms as scrutiny grows.
→The sale as a scheduled event may simply disappear from retail altogether.
The open question is whether software-set pricing earns the same trust a scheduled sale once did, or whether shoppers start assuming they’re always being gamed.

The panel on this signal
They agreed on
–Markdown software runs in named stores, not only in a forecast, a pilot or a vendor claim.
–Scale determines who can afford to compete on this.
–Trust, not the underlying technology, is the genuinely open question here.
The behavioral economist disagreed on
–Price trust in retail has historically eroded once shoppers detect a pattern behind a moving number, as seen with dynamic airline fares; algorithmic markdowns risk the same trust erosion once the mechanism becomes visible.
