Packs
The add-on lets the store sell a product not only by pieces, but also by packs. Customers see clear quantities on the storefront, while the cart, checkout, and stock calculations take the number of units in each pack into account.
What it is for
The add-on is useful for stores that sell products in boxes, cartons, bundles, or other package-based quantities. It helps keep the storefront price clear for customers while preserving correct accounting for packed sales.
Key features
- sell products by piece, by pack, or in a mixed mode;
- configure the number of units per pack globally and for individual products;
- choose how prices are calculated: per unit or per pack;
- display pieces, packs, or both quantity types on the storefront;
- automatically recalculate quantities when customers change pieces or packs;
- display pack quantities correctly in the cart, mini-cart, and checkout;
- support UniTheme2 and responsive checkout product lists;
- bulk edit, export, and import pack-related product data.
How it works
The administrator sets the sale rules and can override them for individual products. On the storefront, shoppers change the number of pieces or packs, and the add-on recalculates the linked value automatically. In the cart and at checkout, the product keeps the correct quantity, price, and line total.
Location in admin
Main settings are available in Add-ons → Manage add-ons → MS: Packs. Product-level settings are available on the product editing page in the MS: fractional stock and packaging tab.
Who it is for
The add-on is useful for wholesale and retail stores, B2B storefronts, and any catalog where products are often sold as sets or packs.
