Reorder List
Days of CoverHow long each line lasts, and when the order has to go.
Running out is expensive and ordering early is expensive, and the line between them is a lead time nobody writes down. Shopify’s Stocky, which did this for its own merchants, was retired on 31 August 2026.
Drop the stock export you already get, tell it which column means what, and it works out how long each line lasts at the usage you gave it and when the order has to go to beat the lead time. Your file is read by the page and never uploaded.
About this tool
What Reorder List solves
Days of cover is one division and this keeps it as one. What is on hand divided by what goes out in a day is how long a line lasts; take the supplier's lead time off that and you have how long before the order has to go. Everything else is the owner's: how many days their usage figure covers, how much buffer they want on top, and how far ahead they order for. It reads a spreadsheet dropped straight onto the page, guesses which column means what from the owner's own headers, and SHOWS the guess so it can be corrected, because a tool that matched the wrong column silently would do confident arithmetic on the wrong number. It forecasts nothing, fits no curve and smooths nothing. It invents no safety stock: the buffer starts at zero, because a margin nobody chose is a number the page made up. And it never states the date you run out, because that is a promise about the future rather than a division.
Yours would be built the same way.
This one runs on made-up data. The version built for your business runs on yours, and you own it outright. Builds start at $2,500. That is a floor, not a quote. What yours costs is agreed before any work begins. The first conversation is free.
