Mass Price Updater is a module for PrestaShop stores that changes many prices in one job: a whole catalogue, or exactly the products and combinations you pick, with a preview of every new price before anything is written. After installation its pages are in the back office and the first job takes minutes.
Supplier increases, promotions and margin corrections rarely concern one product. Changing each price by hand repeats the same arithmetic hundreds of times, leaves typing errors in a live store and keeps no record of what the prices were before.
A job is one form: the products, the price, the change. Behind it sits the full depth: selection by category, brand, supplier, feature, stock, price range, reference and many more filters, combinations chosen by size or colour, a different change per attribute value, price conditions, and amounts with or without tax.
The job runs at once or at a date you set, with an undo date for promotions. Every price change in the store is recorded with its source, whether this module, the product page, an import or a discount, and each product shows its own price history on its product page.
You reprice in minutes instead of evenings and see every result before it exists. A mistake ends as one undo, not as products repaired one by one.
