You stay in control
Nothing changes until you click.
Every price change waits for your confirmation, one product at a time. When a test ends, the price stays where it is until you choose.
YOUR GUARDRAILS
- Nothing changes on its ownNothing reverts or ends by itself. A finished test keeps its price until you decide.
- One product at a timeYou confirm every price change before it reaches your store.
- Gift cards are never testedThey are left out of price tests and suggestions.
- A record of every testPast tests keeps the price, sales and profit before and during each test.
- Discounts have a floorNo sale price below your lowest allowed price: cost plus 10% by default.
Try the math
What if fewer people buy at the higher price?
Say you sell 98 a week at $19.00, and each one costs you $10.00. Move the slider to see what happens at $20.00. Every suggested test shows its break-even before you start.
WORKED EXAMPLE
Before: 98 × $9.00$882 a week
At $20.00: 94 × $10.00$940 a week
Difference+$58 a week
You sell fewer, but each sale earns $1 more. The higher price still wins.

How does a price test work?
You pick a product and a test price. We compare the 28 days at the new price with the same product before the test. You see profit, units sold a week, and break-even. A suggested test shows the extra profit we expect if sales hold.
Is this an A/B test?
No. Every customer sees the same price at the same time. We compare the test with the same product before it started.
Does anything change my prices automatically?
No. Every price change is confirmed by you, one product at a time. Starting a test changes the live price, and you confirm that first. Nothing reverts or ends on its own. When a test finishes, the price stays where it is until you decide.
What happens at the end of a test?
The test card says “Needs a decision” and asks you to Keep or Go back. We recommend one of them and give a one-line reason, for example “Profit is up 11% a week. We recommend keeping it.” The price stays as it is until you click. Keep records your decision and leaves the price alone. Go back sets the old price.
Can I run many price tests at once?
It depends on your plan. Free runs 1, Starter runs 3, Pro and Scale run as many as you like. A test holds its slot until you decide to keep the price or go back. You start each test one at a time.
What does the Free plan include?
One price test at a time, using our suggested tests at our suggested price. You see your top suggested price. Inventory Forecasting covers up to 25 variants. One location. Discount Engine starts on Pro. Free keeps your results when a test runs to its end date. If you stop a test early on Free, you lose the results so far.
Do I need product costs?
Yes, to find price tests. Profit needs a cost for each product, and we need enough recent sales to suggest a price. If costs are missing, we show Inventory Forecasting first, with a prompt to add product costs to unlock price tests.
What happens if I downgrade or cancel?
If you have more tests running than the new plan allows, we warn you first. The earliest-started tests keep measuring, up to the limit. Your prices never change on their own, and Go back stays available for every test.
Is there a free trial?
Yes. Starter, Pro and Scale each include a 14-day free trial. You can use the Free plan at any time. We email you 3 days before the trial ends, with a warning if you have more tests running than your next plan allows.
Your first price test is already waiting.
Install free, and we’ll find the product worth testing first. Keep the new price only if profit goes up.
