Quick answer

Avoid running out of stock on the products that sell the most by marking best sellers for inventory tracking and checking the reorder list weekly. The Metrics page shows top products by units sold and how many are at or below threshold. A weekly email lists urgent restocks first.

Key takeaways

  • Mark your best sellers for inventory tracking so the system knows when stock drops.
  • Set a low-stock threshold for each tracked product to trigger alerts before it hits zero.
  • Check the reorder list and weekly email to see exactly which items need attention first.
  • Central Brain checks inventory-tracked products once a day.

Why do best sellers run out without warning?

Best sellers run out when you track stock by hand and miss the moment a product drops low. On any platform, shoppers come from your own work: your posts, your search listings and word of mouth. Missing one key item breaks that chain.

How do you avoid running out of stock?

Mark the products you sell the most for inventory tracking and set a low-stock threshold on each one. Then check a single reorder list that shows only the items at or below that threshold.

  1. Turn on tracking

    Open each product page and turn on inventory tracking for the ones that move well.

  2. Set the threshold

    Enter the number of units that should trigger a restock alert for that product.

  3. Review the list

    Open the reorder list to see every tracked item that has hit or passed its threshold.

  4. Place the order

    Order replacements for the flagged items before they reach zero.

  5. Review slow movers

    Check the slow-stock list to spot items that need a price change or promotion.

  6. Update counts

    Update the stock count after each new shipment arrives so the list stays accurate.

Say you sell hand-poured candles. You track the three scents that sell the most and set each threshold at ten units. When two drop to eight the reorder list shows them first. The weekly email lists the same items so you order before any run out. For example a home baker shipping cookies tracks the top three flavors and sets thresholds at twenty units each so the list flags only what sells the most.

What shows you which products sell the most?

The Metrics page lists the top five products by units sold in the last 30 days and shows how many inventory-tracked products sit at or below their low-stock threshold.

How often should you check stock levels?

A weekly email arrives with the same list so you order before any run out.

What else flags slow-moving stock or urgent restocks?

Central Brain checks inventory-tracked products once a day and flags items that need a restock or price change.

What does a real example look like?

Say you sell hand-poured candles. You track the three scents that sell the most and set each threshold at ten units. When two drop to eight the reorder list shows them first. The weekly email lists the same items so you order before any run out. For example a home baker shipping cookies tracks the top three flavors and sets thresholds at twenty units each so the list flags only what sells the most. Etrovvo, a platform for independent sellers to build and run their own online store, shows inventory-tracked products on the reorder list. Keeping those two scents in stock is how a small shop can get repeat customers the next time they look.

  • Daily action list: The Brain lists urgent tasks such as orders to ship or products priced at or below their cost.

Frequently asked questions

Do I need to check stock every day?

No daily manual check is required. The weekly email lists items that need restocking so you only act when something shows up.

Can I track stock on every product?

Start with the ones that sell the most so alerts focus on items that matter.

What happens when a product hits the threshold?

The product appears on the reorder list and in the weekly email. From Ascend up the daily scan also flags it.
