Pricing

One thing to decide: how many items you're pricing.

A plan is one number — how many items Marginary prices for you at once. Paused and archived items cost nothing. Every plan gets the whole engine, and Starter's first fourteen days are free.

Count only the items you want Marginary to price. Paused and archived items don't count.

Starter — $49 a month

Covers up to 250 items priced at once.

The first fourteen days

Judge it on your own catalogue, free.

Starter's first fourteen days cost nothing. The engine runs against your real listings from the first hour and writes down every decision it makes — a fortnight is long enough to read it back and decide whether you agree with it.

What the trial does

Everything Starter does. Connects Amazon, pulls your listings, works out your floor from your real costs, runs every pricing cycle, and writes the full reasoning for every decision.

One button

Stop it whenever you want

The emergency stop freezes every price where it is and keeps writing down what it would have done, so nothing is lost by pressing it. Nothing is priced at all until an item has a cost and a minimum price.

Included everywhere

Only two rows in this table ever change.

There is no feature-gating ladder. You are buying capacity, not capability.

Scroll the table sideways to see every plan.

What each plan includes. Only the item capacity and the free trial change between plans.

Billing questions

The bits people ask before paying.

What counts towards my item limit?
Only items Marginary is actively pricing. Paused and archived items cost nothing, so you can keep your whole catalogue in and price a subset of it.
What happens if I go over the limit?
Marginary stops adding new items to pricing rather than silently charging you more. It tells you how many are waiting and which plan would cover them.
What happens at the end of the fourteen days?
Starter begins billing at $49 a month. If you decide against it before then, cancel and nothing is charged — your prices stay exactly where they are and your decision log stays readable.
Do I have to pay to see what it would do to my prices?
No. Preview shows you what the engine would decide for an item without changing anything, on every plan, and nothing is priced at all until you have given it a cost and a minimum price.
What if I stop paying?
Pricing stops. Your prices stay exactly where they were, and your decision log stays readable.

Decide after you've read a fortnight of it.

Fourteen days free, on your real catalogue, with an emergency stop from the first hour. Decide once you know whether you trust it.
