One catalogue, every store
updated the moment it changes
Running the same products across several stores means a stock count, a price or a description goes out of sync the moment one platform updates. The others don't hear about it. We build an agent that treats one system as the source of truth and pushes every change to every connected store the moment it happens.
Why two stores never stay in sync on their own
Running the same catalogue across two or more stores creates a sync problem the moment any one of them updates independently. A stock count drops on Shopify after a sale, but the number on a marketplace listing doesn’t move until someone manually checks. In that gap, a customer orders something already out of stock. Retailers running multiple channels without a real sync layer commonly name overselling as one of their most frequent and most damaging operational failures. It means refunding a customer, apologizing, and sometimes losing standing on the marketplace itself.
Price and description drift cause a quieter version of the same problem. Say a price updates in one place during a promotion and doesn’t propagate everywhere. That means either underselling on the channels that missed it, or a customer screenshotting the mismatch and asking which price is real. Manual reconciliation, someone checking every channel against the master list on a schedule, catches some of this. But the gap between update and reconciliation is exactly where the damage happens. The person doing the checking has other work competing for their time.
What the agent keeps lined up
One source of truth. Your team defines which system leads: your main store, your warehouse system, or a dedicated catalogue tool. Every other channel takes its data from that one place instead of being maintained independently.
Real-time propagation. Stock, price and description changes push to every connected channel within minutes of happening in the source system. That closes the gap where overselling and price mismatches happen.
Conflicts resolved by rule, not by guess. Resolution logic your team defines upfront handles the cases where two systems genuinely disagree. Only the cases the rules don’t cover get escalated to a person.
Mismatch alerts before anything goes live. Take a sync that would push a clearly wrong value: a stock count that jumped impossibly, a price that dropped to zero. It gets held for review instead of landing on a customer-facing page.
A full audit trail. Every field changed, where and when, gets logged. A discrepancy a customer or support agent flags can be traced to the exact sync event that caused it.
A scheduled reconciliation pass runs underneath the real-time sync. It catches slow drift that an individual update might have missed and confirms every channel still matches the source of truth.
What stays with your team
The agent propagates and reconciles. It does not decide a pricing strategy or a stock allocation policy across channels. Conflict resolution rules are set by your team, not invented by the agent, and any conflict outside those rules gets escalated rather than guessed at. A detected sync error that could affect live customer-facing pricing triggers a rollback to the last known-good state and a human review before any retry.
Guards
A parallel-run period lets the sync operate alongside your existing process, with results compared before cutting over fully. A field-mapping error surfaces in testing, not on a live store. Every sync event is logged per field, per channel, with a timestamp, so any discrepancy is traceable. A scheduled reconciliation pass catches drift between real-time updates. Rollback to the last known-good state triggers automatically on a detected error, and a kill switch stops sync instantly across all channels.
Price and timeline
| Package | Price | Best for |
|---|---|---|
| Single automation | from $1,500 | Two to three stores or marketplaces synced against one source of truth |
| Department package | from $2,500 | Catalogue sync plus listing generation and pricing rules across your full channel footprint |
7 to 14 days. Most of it is spent on field mapping and a parallel-run period, so the first live sync has already been validated against real data.

Shares its field mapping with marketplace listing generation and feeds directly into pricing rules and margin guards, since all three depend on the same source-of-truth catalogue. Also underpins order fulfilment routing, which needs accurate stock data to route an order correctly.

FAQ
How much does an AI catalogue sync agent cost?
Syncing two to three stores or marketplaces against one source of truth starts from $1,500. A department package covering sync plus listing generation and pricing rules starts from $2,500. Exact price depends on how many channels and SKUs are involved.
How long does it take to go live?
7 to 14 days. That covers defining which system is the source of truth and mapping fields across every connected store. We then run sync in parallel with your existing process before fully cutting over, so a mapping error surfaces in testing, not on a live store.
Which tools does it connect to?
Shopify, WooCommerce, Amazon, eBay and similar platforms through their own APIs. Your warehouse or inventory system acts as the stock source, with Google Sheets for smaller operations. Claude resolves ambiguous conflicts and flags mismatches that need a human decision.
What if two stores disagree about stock or price?
Conflict resolution rules get set with your team before launch: which system wins for which field. Any conflict the rules can't resolve automatically is flagged for a human rather than guessed at. A scheduled reconciliation pass also catches drift that real-time sync might have missed.
Is our catalogue and sales data safe?
The agent connects through credentials you control, scoped to the stores and marketplaces you approve, and does not retain your catalogue or sales data outside the sync session. Every change is logged so any discrepancy can be traced back to its source.
