# Keep Listings in Sync When Products Change

> What updates automatically when your product data changes — prices, inventory, identifiers — and when to re-run Prompts to refresh AI-written content.

When your product data changes, most of the flow takes care of itself: Osello re-imports the product, and prices, inventory, and identifiers move on their own. The one decision left to you is when AI-written listing content should be refreshed — and that's a Prompt away.

## What syncs automatically

- **Product data.** When you edit a product in your store, Shopify notifies Osello and the product is re-imported — changes typically land in Osello within minutes, and a full nightly refresh catches anything missed. Osello never edits your source data; it only reads it.
- **Prices.** Change a price and the affected offers refresh immediately, then push to your marketplaces automatically wherever offer pushing is enabled.
- **Inventory.** Stock levels are pulled every hour (with a full daily refresh) and flow to marketplaces through your offers.
- **Identifiers.** SKU and barcode changes on a variant update the matching listing variants right away.

## What deliberately stays put

Listing fields that are already filled — whether the AI wrote them or you did — keep their values when product data changes. That's intentional: a listing that's approved and selling shouldn't have its content churn every time a product record is touched. You stay in control of when marketplace-facing content gets rewritten.

## When to re-run Prompts

After a meaningful product change — a rewritten description, a new fabric, updated images — re-run the AI on the fields that depend on it:

- **One listing:** open it, and on the **Fields** tab check the affected fields, then choose **Fill in With AI**.
- **Many listings:** on the marketplace's **Listings** page, select them and choose **Fill in With AI**. Uncheck **Skip filled values** so the AI redoes fields that already have values — leave it checked and it only fills gaps.
- **Just the gaps:** use **Fill in Missing Fields** from the **...** menu on the Listings page to fill every unfilled field across the marketplace.

Each run creates Field Prompts you can watch under **AI** > **Field Prompts**, with before and after values for every field so you can see exactly what changed.

## Getting changes onto the marketplace

Price and inventory changes push on their own. Content changes — field values, images, titles — need a submission to reach the marketplace: a listing edited since its last submission shows "changes are pending submission" on its status badge until you resubmit it.
