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, while competitors moved and your own supplier cost moved with them. We build an agent that watches every marketplace you sell on, reprices within minutes of a real change, and refuses to go below a margin floor no matter how aggressive the competition gets.
The process today
Prices on a marketplace listing are set once, usually at launch, and then drift out of date because nobody is watching the two things that actually determine whether a price still makes sense: what competitors charge for the same product, and what your own cost to fulfill it is now. Supplier costs change, marketplace commission rates get adjusted, and a competitor undercuts a listing by a few percent, none of which triggers an alert on a store that reprices manually maybe once a quarter. Industry marketplace benchmarks commonly estimate that unmanaged third-party listings lose the buy box or top placement to a better-priced competitor within days of a price change elsewhere, often without the seller noticing for weeks.
The risk runs in both directions. Price too high and a listing loses visibility to a cheaper competitor; price too low, whether chasing a competitor or from a stale cost assumption, and every sale at that price loses money, which is worse than no sale at all because 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 simply 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 specific marketplace’s fee and commission structure already factored in, so the floor reflects what you actually keep, not the sticker price.
Logs the reason behind every price change, so a sudden move is traceable to the exact competitor listing or cost update that caused it.
Flags suspicious competitor price drops, like a price that looks like a pricing error rather than a real strategic move, so the agent does 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 that is worth it.
What stays with humans
The agent reprices within the floor you set, it does not decide what that floor is or run a promotional pricing strategy. Any change to the margin floor itself, a decision to run a loss-leader on a specific product for strategic reasons, or a response to a competitor’s price war that goes beyond normal repricing, stays with your team. If the agent cannot compete without crossing the floor, it holds its price and flags the gap rather than making the call itself.
Guards
A dry-run period where the agent calculates every price move without pushing it live, so the margin floor and fee calculations are confirmed correct against your real catalogue before anything changes a live listing. After that, the margin floor is a hard check before every push, not a soft target, every price change logs its trigger and is 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, and a kill switch pulls the agent off any marketplace or product line instantly.

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 which should share one source of truth for cost. Part of automation of everything digital and built the way we build AI agents for our own products. Our own numbers on this exact problem are in the case studies: the 25,746-listing pricing engine across 19 regions, the margin guard on ProBay verified against 864 orders with zero below cost, and the competitor and distributor monitoring inside our two-brand analytics hub that 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: defining your actual margin floor per product including every marketplace's fee structure, connecting competitor and cost data, and 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, Digiseller and similar) for listing and buy-box data, your supplier or cost system for the margin floor, and 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 to compete, the agent holds its price and 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, and we do not retain your cost structure outside the repricing pipeline. Access can be revoked at any time.
