The Vertex Network

Operator tools for the people who actually ship.

The Vertex Network is a small group of focused utilities for solo operators and small teams running e-commerce stores and paid-social campaigns. Each tool is single-purpose, free to start, and built against the same principles: no accounts where one isn't needed, no upsell to a demo, no surprises in the URL bar.

EtsyMargin

What ties them together

· Single-purpose. Every tool solves one boring, expensive problem — not a suite of features.
· Free to start. Paid tiers exist where the work scales (bulk paste, export, advanced configurations). No demo, no retention call.
· URL-first state. Wherever possible, the share-link is the database. Nothing about your work is stored on our servers.
· Authentic data. Specs, fees, and limits are re-verified against the live source — not scraped, not approximated.
