Why skip the first few days of a launch?

Launch-week sales are inflated by your email list and most loyal buyers. Days 4 to 10 show demand from everyone else, which is closer to what the product will sell over time.

How do stock-outs affect the read?

A product that sold out for three days looks weaker than it is. Claude divides sales by the days it was actually in stock, so the rate reflects real demand rather than empty shelves.

Can ChatGPT or Muse run this?

Yes. The prompt works with any assistant that can read your Shopify sales and inventory, including ChatGPT, Grok and Muse, through a connection or an uploaded export.

What if I didn't set a sales plan?

Compare with a similar past launch over the same days instead. That still shows whether the new product is running ahead of or behind what you would normally expect.

Read early sales on a new drop and reorder fast

Early sales on a new product can tell you whether to reorder within about ten days, if you adjust for stock-outs and discounts. Connect Shopify to Claude and ask it to compare sales per day with plan for products launched in the last 30 days. Judge on days 4 to 10, then reorder strong sellers.
