Selling in store and online from one stock

Two lists of products always drift apart. Here is how to run the counter and the website from one catalog without overselling.

Many shops start selling online with a second list of products: the website has its own catalog, its own prices and its own stock count. It works for a while. Then a customer buys online the last unit that just sold at the counter, and someone has to call and apologize.

One catalog, one source of truth

Pick one place where products, prices and stock are decided, and let everything else follow it. For a store with a register, that place is usually the system behind the register, because that is where most stock moves.

Before you connect

  • Clean the catalog first. One product, one SKU. Remove duplicates and old items you no longer sell.
  • Count your stock. Connecting a wrong count only spreads the mistake faster.
  • Decide which location feeds online orders. If you have a stockroom and a sales floor, choose which one ships web orders.
  • Keep a small buffer on fast sellers. If an item sells out every weekend, consider holding back a unit or two from the website.

After you connect

  • Put returns back into stock the same day, whether they came from the counter or the website.
  • Check a few products every morning during the first weeks to confirm the counts match.
  • Change prices in one place only.

When the counter and the website share one stock, a sale anywhere updates the count everywhere. That is the whole point: less typing, fewer apologies, and one set of numbers to trust.
