Yes, channel publishing is per product; most sellers start with proven movers per channel and expand by data.
Read the full answerCan I pause sync for one channel?
Yes, per channel: pausing stops pushes to it while everything else keeps syncing; resume re-aligns it from the hub.

Read the full answerDo channel promotions affect my synced prices?
No: promotions you run on a channel are yours; price rules set base prices and never react to a sale event.
Read the full answerDo I need GTINs or barcodes for sync to work?
No, sync keys on your SKUs; GTINs matter where marketplaces require them at listing time.

Never. SKUs and orders are unlimited on every plan, Standard included. You pay for channels, not for growth.

Bundle-aware stock is on the roadmap at the Plus tier; today bundles work as their own SKUs with deliberate quantities.

Read the full answerDoes the sync hold up during flash sales and Q4?

By per-variant SKU: each size and color is its own synced identity, mapped to each channel's variation model.
Read the full answerHow do I run a proper sync test?
One SKU, two channels, one stopwatch: buy on channel A, watch channel B update in seconds, then check the log.
Read the full answerHow do I see if my sync is actually working?
The sync-health dashboard shows per-channel success rates and staleness, and every push is logged with its timestamp and result.
Read the full answerHow do I stop overselling across channels?
Fix the root cause: one authoritative pool with second-level propagation, plus buffers on thin SKUs.
Read the full answerHow do safety buffers work?
A buffer holds back part of your real quantity per channel, so fast channels cannot promise the last units during sync propagation.
Read the full answerHow does price sync work?
Price follows your per-channel rules: mirror the source, apply a markup, or scope rules by channel and category on Plus.
Read the full answerHow fast do restocks show up on my channels?
In seconds: a receiving update at your source is a stock event like any sale, fanned out immediately.

Under 3 seconds: a sale fires an event the moment it happens, so every channel learns the new quantity in seconds, not on a polling interval.
Read the full answerHow many products can the platform handle?
SKUs are unlimited on every plan, and the platform is benchmarked with a million-SKU catalog.
Read the full answerIs there a developer API?
A public developer API is on the roadmap at the Professional tier; today every channel connection uses official platform APIs.
Read the full answerWhat are conflicts in the sync-health view?
Moments where a channel's value disagreed with the hub and had to be corrected, surfaced so patterns are visible.
Read the full answerWhat counts as a sales channel?
Your source-of-truth store is free to connect; only the additional channels you distribute to count toward your plan.
Read the full answerWhat does event-driven sync actually mean?
The sale itself triggers the update: webhooks and plugins push events instantly instead of a timer asking on an interval.
Read the full answerWhat happens if I disconnect a channel?
Its grant revokes and pushes stop; the channel keeps its last quantities and your listings stay untouched.

The hub is the single authority: sales apply to it in order, stale events are dropped, and the result fans out to every channel in seconds.
Read the full answerWhat happens when a marketplace API is down?
Failed pushes retry automatically, the failure is visible in the sync log, and alerts can notify you; the backstop reconciles once the channel returns.

When your channel restocks the cancelled order, that stock change reports like any other and fans out in seconds.
Read the full answerWhat if my channels disagree about stock when I connect?
The source of truth wins: the hub adopts its quantities as the baseline and aligns the other channels from there.
Read the full answerWhat is a source-of-truth store?
The store that owns your master inventory: it feeds the hub, is free to connect, and destination channels mirror it.
Read the full answerWhat is the scheduled backstop sync?
A periodic full reconciliation that backstops the event stream: hourly on Standard, every 30 minutes on Plus, every 15 on Professional and Enterprise.
Read the full answerWhich crosslisting platform is best?
Separate the jobs: crosslisting publishes listings, sync keeps them true; judge tools by documented sync speed and what they meter.

Quantity always; price only under your rules; product content on publish; nothing else is touched.
