Overview

RepriceLab syncs your product catalog from Amazon automatically after you connect a store. If products are missing, duplicated, showing stale data, or not updating correctly, this guide covers the most common causes and how to fix them.

Products not appearing after connecting a store

Initial catalog sync takes 15–30 minutes for most catalog sizes. For catalogs with more than 5,000 active SKUs, expect up to 60 minutes. If products have not appeared after this window:

  • Verify your store status is Active on the Multichannel page (not Disconnected or Auth Error)
  • Confirm the correct marketplace was selected — for example, if you sell on amazon.de but connected amazon.co.uk, your listings will not appear
  • Check that your Amazon listings are Active — Inactive, Stranded, or Suppressed listings may be excluded from the sync
  • Trigger a manual sync: go to Multichannel → click the options menu next to your store → Sync Products

Missing SKUs

If only some products are missing (not all):

  • Stranded inventory: Amazon marks some SKUs as stranded when there is a listing issue. These are excluded from active inventory feeds. Resolve stranded inventory in Seller Central under Inventory → Fix Stranded Inventory.
  • Listing quality issues: Products with suppressed listings, missing required attributes, or policy violations may not appear in the SP-API catalog response.
  • New listings: Freshly created listings can take 24–48 hours to be fully indexed by Amazon and to appear in SP-API responses. Trigger a manual sync after 24 hours.
  • Multi-condition listings: If you sell the same ASIN in both New and Used condition, each condition appears as a separate product in RepriceLab.

Inventory quantities are wrong

RepriceLab pulls FBA inventory quantities from Amazon at each sync cycle. If the quantities shown in RepriceLab differ from Seller Central:

  • Allow up to one repricing cycle (10 minutes) after a Seller Central inventory change for RepriceLab to update
  • FBA inventory updates from Amazon can themselves be delayed by 15–30 minutes after physical check-in at a fulfillment center
  • For FBM inventory, quantities are set in Seller Central and RepriceLab reflects them as Amazon reports them — there is no separate FBM quantity override in RepriceLab

Product prices in RepriceLab do not match Seller Central

If the price shown in RepriceLab differs from what is currently live on Amazon:

  • RepriceLab changed the price: Check the Repricing Activity log. If RepriceLab submitted a price update, it will appear there. The price in RepriceLab reflects the last price RepriceLab is aware of.
  • Price was changed in Seller Central: If you manually changed the price in Seller Central after RepriceLab's last cycle, RepriceLab will detect this on the next sync and update its records. This is normal.
  • Sale price conflict: If a product has an active Sale Price in Seller Central, Amazon displays the sale price on the listing. RepriceLab manages the regular price only — sale prices set in Seller Central take precedence until they expire.

Sync retry process

If a manual sync does not resolve missing products after a few minutes:

  1. Disconnect the store from the Multichannel page
  2. Wait 5 minutes
  3. Reconnect the store using the Connect Amazon Store flow
  4. A full catalog re-sync will begin automatically

Note: Reconnecting a store does not delete any historical repricing data, COGS entries, or activity logs for products in that store. Your data is preserved throughout the reconnection process.

Duplicate products

If the same product appears twice in RepriceLab, this is usually caused by:

  • The same ASIN listed under two different SKUs in Seller Central — RepriceLab creates one entry per SKU
  • Connecting both North America and Europe store accounts when the same ASIN exists in both — RepriceLab tracks each marketplace separately

Duplicates can be identified by checking their marketplace and SKU in the Products page. If genuine duplicates exist for the same SKU and marketplace, contact support.

When to contact support

Contact RepriceLab support if:

  • More than 20% of your catalog is missing after 2 hours and a manual sync
  • Products disappeared after previously syncing correctly
  • You see duplicate entries for the same SKU within the same marketplace
  • Reconnecting the store does not restore missing products
