What Flux could earn for your store
Move the sliders, then open our assumptions and push back on them. Every number here is an estimate - you can see exactly how we get there.
Your store
What you'd take off sitewide instead of using Flux. Most sitewide sales run 10-30%, so we start at 20%.
Free to install. Flux only earns when it completes a sale for you.

About 0.5% of visitors become a recovered sale. Bars after the first are scaled up 6x so you can see them.

How we get to the number
There's no black box. Four rates turn your traffic into recovered sales, less the discount and what you'd pay Flux. Then we put that next to the sitewide sale you'd otherwise run, and show the difference. The maths alongside updates with your inputs.
We only count one thing: shoppers who hesitate on price, negotiate, and land on a number above your floor. Nothing else Flux does is in the total.

Commission applies to the negotiated order value only. We pick whichever plan costs you least at this volume. The sale is modelled as running all month, on every order.
Why our defaults sit on the low side
These are our estimates, not measured results from your store. Here's the thinking behind each one - and you can change any of them above.
3%
open a negotiation
Most visitors never get near a price decision. We only count the few who tap to make an offer on a product page, and keep that share small.
55%
reply at least once
Opening the chat isn't the same as engaging. We assume almost half leave after the first message and never make a real offer.
30%
of those, Flux closes
Flux never goes below the floor you set. When a shopper's number sits under it, there's no deal - and we assume that happens most of the time.
10%
average Flux discount
Every closed deal is modelled at 10% under list. You set floors and rules per product, so you decide how deep it can ever go.
1.5%
your normal conversion
Close to the ecommerce average. These are the orders a sitewide sale discounts - every one gets the cut, even though they'd have bought at full price.
Same
extra orders, both ways
We give your sale exactly the same extra orders as Flux. The only difference is the discount: a sale cuts every order, Flux only the ones that needed it. Your usual discount is set above - we start at 20%.
Put together, about 0.6% of visitors become a recovered sale at our defaults - roughly 40% on top of your normal orders.
What the estimate doesn't count
The calculator counts one thing: negotiated sales on your product pages. Here's what it leaves out on purpose.
No code to leak
A negotiated price is private to one shopper. There's no public discount code for coupon sites and browser extensions to pick up and spread.
Discounts sized to the deal
A sitewide code hands every buyer the same cut. Flux finds each shopper's yes-price above your floor, so the discount fits the deal instead of the calendar.
The second order
We count one order per recovered shopper. Each one is now a customer you can email and retarget - repeat purchases aren't in the number.
Stock that sits
Aged or seasonal stock can move at a floor you choose, privately, without a public markdown that resets what shoppers expect to pay.
Pricing you can learn from
Every negotiation shows what shoppers actually want to pay, product by product. That's pricing data you'd normally need weeks of A/B tests to get.
AI shopping agents
Flux works with agentic commerce, so AI assistants like ChatGPT can close a price for a shopper. Shopify reported AI-driven traffic to stores up 8x year on year in Q1 2026. None of that is modelled.
When it could come in lower
Know these before you bank on the number.
Mostly low-intent traffic
Blog, social and giveaway traffic browses more than it buys. Fewer shoppers reach a price decision, so fewer negotiations start.
Very low price points
On a $10 item most shoppers won't bother - there's not much to win. Flux earns most where the price is a real decision.
Floors close to list
If your floor sits near your list price, fewer offers clear it. That protects margin but closes fewer deals than the model assumes.
Some would've bought anyway
We count every closed deal as a recovered sale. Some negotiators might have checked out without one - your floor caps what that can cost you.
Month one isn't month three
Floors and rules take tuning to your catalogue. Expect early weeks to look different from where you settle.
Revenue isn't profit
Recovered revenue is before product cost, shipping, payment fees and tax. Flip on 'Show profit' above for a margin view.
The only number that matters is yours
Run it in parallel. See your real number.
Switch Flux on for a handful of products and leave everything else exactly as it is. If it closes nothing, you pay nothing.

- This calculator is illustrative. It isn't a forecast, a guarantee or financial advice, and your results will depend on your traffic, products, prices, floors and rules.
- The default rates are Flux's own conservative estimates. They aren't measured results from your store or an average across Flux merchants.
- "Revenue recovered" assumes each closed negotiation is a sale that wouldn't have happened otherwise. Figures are before product costs, shipping, payment fees and taxes.
- Plan prices match our pricing page at the time of writing. Commission applies to the negotiated order value only. Figures are shown in USD for illustration - you're billed in your store currency.
- Annual figures assume your monthly volume holds flat for 12 months.
- The sitewide-sale comparison assumes the sale runs all month, on every order, and brings in the same extra orders as Flux. It leaves out what a sale costs to promote, and shoppers learning to wait for the next one.
What happens if a customer refunds their order?
If an order is refunded, the commission for that order is automatically reversed. You only pay on revenue you actually keep.
Can I cancel at any time?
Yes. There are no contracts. Uninstall Flux whenever you want and you stop paying commission immediately. There's no penalty for leaving.
How am I billed?
Shopify merchants are billed through Shopify's built-in billing system, with commission charges appearing in your Shopify admin alongside your other app fees. Merchants on other platforms are billed directly via Stripe. Billing runs monthly — no manual invoicing, no chasing.
