S09.9 · Retail & Commerce
Storefront, checkout and fulfillment software providers now rebuilding for agent-initiated purchases.
Commerce enablement — the storefront, checkout, order-management and fulfillment software layered on top of retail operators — is growing double digit, ahead of underlying retail sales, as more commerce volume shifts onto composable, API-based infrastructure and off in-house systems. Shopify alone processed more than $300B in gross merchandise volume in 2024/2025 (public filings). No clean total addressable market exists — research-mill estimates for the category run from roughly $8B to more than $100B depending on scope — but the economic engine is unambiguous, and it is the segment's real story.
Vendors concentrate in the US and Canada — Shopify, Adobe Commerce and Salesforce Commerce Cloud among them — while demand is global. The platform layer is moderately concentrated over a long tail of point solutions in checkout, subscriptions, fraud and tax. The segment sits between retail operators and the payments and logistics rails and monetizes through subscription revenue plus a payments take rate, producing software-style gross margins of 65-80%+, recurring revenue and low capital intensity — a structurally different economic profile, and a structurally different buyer universe, from the retail operators it serves.
The blended model compounds two ways at once: new merchants grow the subscription base, and GMV growth on existing merchants grows the payments line with no incremental sales cost. That beats pure SaaS, which caps out on seat count, and pure payments, which lives on volume alone — and it is why platform vendors have pushed so aggressively to own checkout and payments rather than leave that revenue to third parties.
The push into payments and checkout goes after more of the transaction take rate; fraud and compliance tooling is the non-discretionary line customers buy in any growth environment. AI now cuts at the core product from two directions. It is rebuilding the checkout and discovery layer for agent-initiated purchases, which strikes directly at what this segment sells, and it is simultaneously compressing the cost of building a storefront in the first place — no-code and AI-generated stores are pressuring pricing at the low end of the subscription base even as they open a new, higher-value layer above it.
A distinct, fundable sub-category is forming around "agentic commerce infrastructure": agent-readable product catalogs, machine-executed checkout, and agent identity and fraud detection built for non-human buyers rather than humans clicking through a cart. The shift is already underway rather than speculative, and it is sorting the segment into vendors positioned to capture the next layer of commerce infrastructure spend and vendors defending a shrinking subscription base.
