Read the transcript
This is GrtLabs Runway, a read-only reorder and inventory report. It opens embedded right inside the Shopify admin.
Each row is a SKU. You see sales for the last 30, 60 and 90 days, stock at each location, total on hand, and days of cover.
Sales show zero here because access to Shopify’s sales reports, which count as protected customer data, is still pending Shopify’s approval. The yellow banner explains this. The stock levels you see are current.
Scrolling down shows every SKU in the store. Filter tabs narrow the list: Low cover, under 14 days; Out of stock; and All SKUs.
The search box finds SKUs by SKU or product name. Searching for Snowboard shows just the matching products. Clearing the search returns the full report.
Click a column header to sort. Here the report is sorted by Total on hand.
Export CSV downloads the reorder list as a CSV file.
The user guide explains each column, the filters, and the export in plain language.
Runway is read-only. It never changes your store data.
Back to the report.
A clear reorder list from your own store data
Runway is a reorder and inventory report from GrtLabs, a Houston AI lab. It is built to run embedded in the BigCommerce control panel and read your orders, products and inventory with read-only access. Runway for BigCommerce is in BigCommerce marketplace review and is not publicly listed yet; contact us for early access. Each row is a SKU. You see units sold in the last 30, 60 and 90 days, on-hand stock at each location, total on hand and days of cover, with the shortest cover first.
Days of cover is total on hand divided by average daily sales over the last 30 days. For example, a mug with 20 on hand that sold 60 in 30 days has 10 days of cover. If a product sold nothing in 30 days, its cover is blank rather than infinite, and those rows sort last.
Runway never changes your products, inventory, orders or prices. It does not create purchase orders or email suppliers. You decide what to buy and place the order in your own process, using the CSV if you like.
What Runway shows you
One table, built for the question every merchant asks before placing an order: what runs out first?
Days of cover for every SKU
Runway estimates how many days of stock each SKU has left at its recent sales pace and sorts the report shortest cover first, so the items that need attention are at the top.
Sales for 30, 60 and 90 days
Units sold in the last 30, 60 and 90 days sit side by side for each SKU, so you can compare recent demand with a longer trend before you reorder.
Stock by location
Each inventory location gets its own column, plus a total on hand per SKU. If BigCommerce does not allow the location read, the on-hand column uses the product’s inventory level.
Stock filters
Filter buttons narrow the list to All SKUs, Low cover (under 14 days), Out of stock, or No sales velocity, where cover cannot be calculated because there were no recent sales.
Search and sort
Search by SKU or product name. Click any column header to sort the whole report, and click it again to reverse the order. Filters stay on while you sort and page through results.
CSV export
Export CSV downloads every row that matches your current search, filter and sort, not just the page you are viewing, ready for your supplier or spreadsheet.
How it works
From early access to a reorder list in four steps. Runway uses read-only access the whole way through.
1. Request early access
Runway for BigCommerce is in BigCommerce marketplace review. Contact GrtLabs for early access. When your store is connected, you approve read-only access to orders, products and inventory.
2. Open the report
Open Runway in your BigCommerce control panel. The reorder table loads for your store with every SKU, sorted by shortest days of cover.
3. Review and filter
Use the filters, search and column sorting to find what is running low. Click a product name to open it in the BigCommerce product editor.
4. Export and reorder
Download the CSV and place the purchase order with your supplier yourself. Runway keeps reading; it never writes to your store.
What Runway does not do
- Create purchase orders or email suppliers.
- Write inventory, change products or edit orders.
- Keep a standing copy of your catalog or sales. Report data is computed when you open the app.
Why GrtLabs
Runway is built and supported by GrtLabs Inc in Houston, the same team behind our AI development work in Houston. We built it to be plain and predictable: read-only scopes, clear numbers and a blank cover instead of a misleading one.
Your store’s access token is encrypted at rest, and app data is hosted in the United States. Uninstalling Runway from BigCommerce removes its access and deletes that store’s data from our database. Details are in the Runway Privacy Policy.
