// what marginfly does

The agent that never sleeps.

Other tools hand you a rules engine and wish you luck. Marginfly reads the same signals a good pricing analyst would — and acts on them while you are doing something else.

Autonomous repricing

No thresholds, no strategy matrices. The agent reads competing offers, your stock and your sales pace, then sets a price. You set a floor; it handles the rest.

Your floor is absolute

A separate layer of plain code — not the AI — clamps every price before it ships. It cannot go below your floor, above your ceiling, or move more than 8% in one step.

A reason for every change

Each price move is logged with what the agent saw and why it acted. When a price surprises you, the answer is one click away instead of a support ticket.

Margin first, not lowest price

Winning the buy box at a loss is easy. Marginfly weighs the margin you would keep against the sale you would win, and walks away from bad trades.

Your data stays yours

Your costs and margins never feed another seller's pricing. Competitive signals come only from offers the marketplace already shows everyone.

One switch stops everything

Pause a single listing, or every listing you own, instantly. Prices freeze exactly where they are until you say otherwise.

// setup

Three steps, one coffee.

Nothing changes on your listings until you press Go live — and you can watch the first round of decisions before anything ships.

STEP 01

Connect your store

Sign in through Amazon and approve access. Your listings, prices and stock import automatically. We never see your marketplace password.

STEP 02

Set your floor

Enter your cost and the margin you refuse to go below — in bulk for the whole catalogue, then adjust anything that needs a different rule.

STEP 03

Go live and watch

The agent starts checking every 15 minutes. Every decision lands in your log with the reason attached, and you can pause it all at any moment.

// the honest comparison

Built for autonomy. Not another rules engine.

Most repricers are good software built before an agent could reason about context. Here is where that difference actually shows up.
