How to automate inventory reorders with AI: low-stock alerts and supplier drafts

Updated · by Rosh Perera

Running out of a best-seller costs sales, and over-ordering ties up cash. A reorder routine checks stock against a reorder point you set, lists what's low, and drafts the purchase order to each supplier for you to approve. AI helps with the reading and drafting; you set the reorder points and approve every order. Not sure which job fits your business first? Answer 5 quick questions in our free planner.

What to hand to an agent first

  • Set reorder points

    For each item: current stock, reorder point (the level where you reorder), usual order quantity, supplier and lead time.

  • Daily low-stock list

    Each morning the agent reads stock from your sheet or store and lists items at or below their reorder point.

  • Supplier order drafts

    It groups low items by supplier and drafts one order email per supplier with items and quantities, for your OK.

  • Lead-time warnings

    It flags items that will likely run out before a new order arrives, based on the lead time you entered.

  • Weekly review

    A Friday note: items that ran out, items that haven't sold in 60 days, and reorder points you may want to change.

Copy-ready prompt

Every weekday at 7:30, read [stock sheet or store inventory] (columns: item, SKU, stock, reorder point, order qty, supplier, lead time days, avg daily sales).
1. List every item where stock <= reorder point.
2. Also list items where stock / avg daily sales < lead time days, as "may run out before delivery".
3. Group the list by supplier and draft one order email per supplier: items, SKUs, order qty, requested delivery date.
Rules:
- Never place an order, change prices or pay.
- If any column is empty for an item, list it as "missing data" instead of guessing.
- Don't send. Post the list and drafts here for my approval.

Setup steps

  1. Build a stock sheet with reorder point, order quantity, supplier and lead time per item.
  2. Connect your store or inventory export read-only.
  3. Paste the prompt below and run it for a week.
  4. Approve supplier drafts and send them yourself.
  5. Adjust reorder points from the Friday review.

Keep these human

  • You approve every order and every quantity; the agent never places an order or pays.
  • Check supplier prices and terms yourself.
  • Give the agent read-only access to your store or inventory tool at first.
  • Start in draft mode: the agent prepares, you approve, then loosen the leash one routine at a time.

FAQ

Can AI reorder inventory automatically?

It can list low stock and draft supplier orders. Keep placing and paying for orders with you.

What's a reorder point?

The stock level where you place a new order so it arrives before you run out. You set it from your sales and the supplier's lead time.

Does this work with Shopify?

Yes. Grok Bot has a Shopify connector, and n8n and Zapier can read Shopify inventory too.

What if my stock counts are wrong?

The routine is only as good as the counts. Do a quick count check on your top items monthly.
