An Amazon repricer that looks at the whole offer, not just the price

Most repricers react to one number: what the other seller is charging. That is the smallest part of why a listing wins the sale.

An Amazon repricer decides what price to set for each of your offers. SellerFlow evaluates the competing offer in full before deciding: listing price, fulfilment channel, delivery promise, the stock it can observe on each rival, and how that competitor has behaved before. It moves prices up, down or holds them, always inside the minimum and maximum you set.

What it evaluates before it moves a price

Two offers at the same price are not the same offer. One ships tomorrow through Amazon; the other takes six days from a seller with 40 ratings and eleven units left. A repricer that only compares numbers treats them as equal, and prices against a rival who was never going to win the sale.

Before setting a price, SellerFlow weighs the competing offer as a whole:

• Listing price and where it sits against the rest of the offers.
• Fulfilment channel — whether the rival ships through Amazon or handles it themselves.
• Delivery promise, because a faster delivery justifies a higher price and a slower one does not.
• Observed stock on the rival, which tells you whether their price will even be there tomorrow.
• Seller rating, weighted by how many ratings it is built on — a perfect score from one review is not a signal.
• How that competitor has behaved before: some react within hours to a price cut, most never move at all.

Where that data comes from

Amazon's Selling Partner API gives you a great deal: featured offers, listing and reference prices, condition, fulfilment channel, offer count. Every serious tool is built on it, and so is SellerFlow.

The difference is what we add on top. SellerFlow reads the live offer panel directly and keeps its own behavioural history for every competitor it meets. In the last 30 days that is 3,006,518 observations across 546 listings, and 799 competitor profiles built from what those sellers actually did, not what they claim.

It will not raise a price it cannot defend

The most expensive mistake a repricer makes is not pricing too low. It is drifting upward while nobody is watching, losing the Buy Box quietly, and sitting there for two days at a price that sells nothing.

SellerFlow does not raise a price unless the current market data confirms the position is defensible. And for every product it remembers the price that actually won the Buy Box, so when it climbs it climbs toward a number that has already worked in the real market, not toward a theoretical maximum.

Built for whichever marketplace you sell in

Currency, tax treatment, time zone and marketplace are configuration, never assumptions baked into the code. The same engine runs on any Amazon marketplace, and an account selling in more than one is a normal case here, not an edge case.

Frequently asked questions

What does an Amazon repricer actually do?

It sets the price of each of your offers automatically, reacting to what competing offers do. The difference between repricers is what they look at before deciding. Some see only competitor prices; others also see delivery promise, fulfilment channel, observed stock and your own cost floor, which lets them defend a price instead of only matching one.

Will a repricer start a price war with my competitors?

It can, if it only knows how to undercut. A repricer that only sees prices has one move available. SellerFlow can hold or raise when the rest of the offer justifies it, and every decision stays inside the minimum you configure, so there is a floor it cannot cross even when a competitor keeps dropping.

Can I stop the repricer from selling below my cost?

Yes, and that is what the minimum price is for. You set it, the system works inside it, and it does not overrule it. If you want to understand how the floor is built from real fees, fulfilment and cost of goods, the profit dashboard is where that calculation lives.

How often does it change prices?

It reacts to what it observes rather than on a fixed schedule. Over the last 30 days the system recorded 17,291 price decisions across 598 SKUs. A decision is a decision, not a guaranteed sale: see how we measure that.

Does raising a price ever make sense?

Yes, when the offer holding the featured position is weaker than yours on delivery or availability, or when there is no competing offer to defend against. A repricer that can only go down leaves that money on the table every time.
