Sync marketplace quantities across linked listings

Before enabling sync

• Both storefront listings must be linked to represent the same item.
• They must represent the same pool of sellable marketplace inventory.
• Each variation must have one unambiguous partner on the other marketplace.
• Both marketplace connections need permission to update inventory.

Enable automatic quantity sync

1. Open the listing’s actions and choose Link or manage listings.
2. Under Marketplace quantities, turn on Sync quantities automatically.
3. Choose which store supplies the starting quantities.

   

4. Review or correct the variation mapping, then save.

How changes propagate

Meldsy checks the latest quantity in each store before updating the linked listing. A confirmed sale or quantity change is then carried across, and regular follow-up checks cover delayed updates.

Manual quantity edits are different

Edit quantities sends the exact whole-number values you enter to the selected marketplace listings. It is useful for a deliberate correction, but it does not enable ongoing synchronization and it never substitutes the Can Make estimate.

When sync pauses

If both sides change in a way Meldsy cannot reconcile safely, writes pause for that linked listing pair while other pairs continue.

• Open the linked-listing settings and read the last sync message.
• Refresh both stores to confirm their current quantities.
• Fix permissions or variation mappings if requested.
• Choose the intended source quantity and save again.

Selection can disable sync

Excluding either listing from Meldsy disables the linked quantity-sync pair. Restoring the listing preserves its setup but does not automatically re-enable inventory writes.
