The same product, five different prices:
none of them checked since launch
A listing priced to win the buy box in January is still sitting at that price in June. Competitors moved, and your own supplier cost moved with them. We build an agent that watches every marketplace you sell on and reprices within minutes of a real change. It refuses to go below a margin floor no matter how aggressive the competition gets.
A price nobody has looked at since launch
A marketplace listing gets priced once, usually at launch, and then drifts out of date. Nobody is watching the two things that actually decide whether a price still makes sense. What competitors charge for the same product. What it now costs you to fulfil it. Supplier costs change. Marketplace commission rates get adjusted. A competitor undercuts a listing by a few percent. None of it triggers an alert on a store that reprices manually once a quarter. Industry marketplace benchmarks commonly estimate that an unmanaged third-party listing loses the buy box within days of a price change elsewhere. The seller often does not notice for weeks.
The risk runs both ways. Price too high, and a listing loses visibility to a cheaper competitor. Price too low, whether chasing a competitor or working off a stale cost assumption, and every sale at that price loses money. That is worse than no sale, since volume multiplies the loss instead of the revenue. A catalogue of any real size, a few hundred SKUs across more than one marketplace, generates enough of these drift events that manual repricing cannot keep up.
What the agent does
Monitors competitor and buy-box pricing continuously across every marketplace you sell on, not a weekly spot check.
Reprices within minutes of a real change, whether that is a competitor’s move or your own supplier cost shifting, instead of waiting for a scheduled review.
Enforces a hard margin floor it never crosses, calculated per product with that marketplace’s fee and commission structure already factored in. The floor reflects what you actually keep, not the sticker price.
Logs the reason behind every price change, so a sudden move traces back to the exact competitor listing or cost update that caused it.
Flags suspicious competitor price drops, the kind that looks like a pricing error rather than a real strategic move. The agent will not chase a mistake down to an unprofitable level.
Reports weekly on win rate and margin by marketplace, so the team can see whether the repricing strategy is actually growing volume at a margin worth having.
What stays with humans
The agent reprices within the floor you set. It does not decide what that floor is, and it does not run a promotional pricing strategy. Any change to the margin floor itself stays with your team. So does a loss-leader decision on a specific product, or a response to a competitor’s price war that goes beyond normal repricing. If the agent cannot compete without crossing the floor, it holds its price and flags the gap rather than making that call itself.
Guards
A dry-run period lets the agent calculate every price move without pushing it live. The margin floor and fee calculations get confirmed against your real catalogue before anything changes a live listing. After that, the margin floor is a hard check before every push, never a soft target. Every price change logs its trigger and stays reversible. Rate limits cap how often a single listing can reprice in a short window, to avoid a feedback loop with a competitor’s own bot. A kill switch pulls the agent off any marketplace or product line instantly.

This depends on the same cost and catalogue data as stock and feed updates, pricing rules and margin guards and fraud and anomaly alerts. All of these should share one source of truth for cost. It is part of automation of everything digital, built the way we build AI agents for our own products. Our own numbers on this exact problem are in the case studies. See the pricing engine for a large multi-currency catalogue with fee-aware margin floors. See also the margin guard on ProBay verified against 864 orders with zero below cost. The competitor price monitoring inside our two-brand analytics hub caught 184 of 218 undercut events with zero false alarms.

FAQ
How much does a multi-marketplace repricing agent cost?
A single product category across two or three marketplaces starts from $1,800. A department package covering repricing plus fraud alerts and affiliate reporting starts from $2,500, priced once we know your catalogue size and marketplace count.
How long does it take to go live?
7 to 14 days. That covers defining your actual margin floor per product, including every marketplace's fee structure, and connecting competitor and cost data. Then a dry-run period where the agent calculates prices without pushing them live, for your team to check first.
Which tools does it connect to?
Marketplace seller APIs (Amazon, Shopee, Lazada and similar) for listing and buy-box data. Your supplier or cost system for the margin floor. Your own catalogue database for which rule applies to which product.
What if the agent reprices below cost?
It cannot, by design. The margin floor is a hard rule checked before every price push, not a target the agent tries to respect. If a competitor's price would require going below that floor, the agent holds its price. It flags the gap for a human instead of chasing it down.
Is our pricing and cost data safe?
The agent reads cost and competitor data through your existing marketplace and supplier credentials, scoped to pricing actions only. We do not retain your cost structure outside the repricing pipeline, and access can be revoked at any time.
