LNK Pack Sizes and Minimum Order, selling by pack and a minimum order per customer group
Your oil bottles leave by cases of 6, your soaps by 12, and your business customers must order at least €300 excl. tax. PrestaShop cannot do either per customer. LNK Pack Sizes and Minimum Order does it with what PrestaShop already does: the cart, its minimum message, and checkout staying closed.

Sell by 6, by 12
Set a pack size on a product, on a combination, or on a whole category. A quantity typed is rounded up to the next multiple, on the product page, in the quick view and in the cart, and an order cannot leave with a quantity outside the pack size. The product page says "Sold by 6", and the quantity field moves 6 by 6 with the theme's buttons.
Give the unit a name if you want: "Sold by box of 6", "Price per box: €53.40 excl. tax" on the product page, "2 boxes (12 units)" in the cart. The box price is PrestaShop's price for this customer, times the pack size. The price per kilo or per litre stays PrestaShop's native unit price.
The server makes the rule: an add coming another way (quick view, list, another module) is brought back to the pack size, and checkout does not open on a cart outside it.
A minimum order per customer group
An amount excluding tax per group: €300 for businesses, nothing for consumers. Until the minimum is reached, the cart shows PrestaShop's message, checkout stays closed, and a line says what is left to add. Other groups keep the shop minimum. The module does not change your shop configuration.
Nothing complicated in the back office
A reference and a pack size, or a category and a pack size; an amount per group. The preview shows the product page notice and the cart line before saving.
Light and fast
Figures measured on the delivered module, compressed (zlib, level 9): 0.4 KB of CSS and 1.1 KB of JavaScript, loaded only on the product page and the cart. Without JavaScript, the rules still apply, on the server.
Compatible with PrestaShop 1.7.6, 8 and 9

Frequently asked questions
What happens if a customer types 7 for a product sold by 6?
The quantity is rounded up to the next multiple: 12. On the product page, in the quick view and in the cart, and the customer sees the right quantity at once. The quantity field moves 6 by 6, and so do its buttons.
Can a customer order a quantity outside the pack size another way?
No. The rule applies on the server, each time the cart is saved, whatever the way of the add (product page, list, quick view, another module). At the checkout entrance, a line outside the pack size is corrected and the customer goes back to the cart with a message.
Can each combination have its own pack size?
Yes. A combination's pack size wins over its product's. You can also set the same pack size on every product of a category.
How does the minimum per customer group work?
You type an amount excluding tax per group. For a customer of that group, the module uses PrestaShop's native minimum with that value, for the time of the page: the cart shows PrestaShop's message and checkout stays closed. Nothing is written in your shop configuration; other groups keep its minimum.
Is the minimum checked at payment?
The module closes checkout, like PrestaShop's native minimum. A payment module that would create an order without going through checkout is not covered, no more than with the native minimum.
How does the customer know what is left to order?
The cart shows PrestaShop's message, and the module adds a line: "Minimum order for your account: €300.00 excl. tax. €120.00 left to add." This line can be hidden.
Can I sell by the box, the pallet, the bag?
Yes. Give the sales unit a name, with the pack size: the product page shows "Sold by box of 6" and "Price per box: €53.40 excl. tax", and the cart "2 boxes (12 units)". The box price is the pack size times the unit price PrestaShop gives this customer for that quantity (group and tiered prices included): the module computes no price. The name is optional; without it, nothing changes.
What about the price per kilo or per litre?
That is PrestaShop's native unit price (Catalog > Product > Pricing > Unit price), shown by your theme. The module does not touch it.
Does it work with LNK Tiered Prices?
Yes, without any setting. When a product has a unit name, Tiered Prices expresses its tiers in that unit: "from 4 boxes", "€167.52 excl. tax per box". Each module also works on its own.
Is JavaScript needed?
Not for the rules: rounding and the minimum are applied by the server. The script only sets the quantity field and its buttons at the pack size step.
Does the module slow my shop down?
No. 0.4 KB of CSS and 1.1 KB of JavaScript compressed, loaded only on the product page and the cart.
Does it work with multistore?
Yes. Pack sizes and minimums are set shop by shop; a new shop takes over those of the shop copied, and a deleted shop takes its own away.
What is left if I uninstall the module?
Nothing. The module has no override; uninstalling removes its three tables, its settings and its tab. The shop minimum was never changed.
