Description

Maximum Quantity for WooCommerce Shops is a simple extension for WooCommerce that only does one thing: it lets you set a maximum limit for the number of items that can be added to the cart, for each product, per order.

It’s like one of those signs at the grocery store that says, “LIMIT 2 PER CUSTOMER!”. This plugin will not add a sign like that, but the quantity input field will hit a limit.

You can set a global limit to affect all products in your WooCommerce store or, if you prefer, a different limit for each product, individually. Each product’s own limit will always override the global limit.

This works for all products in your WooCommerce store: Simple and Variable products.

Customers do not have to be logged in for this to work. This works for guest buyers, as well as logged-in buyers.

This plugin was initially developed by Isabel Castillo and later adopted by Marco Almeida | Webdados / PT Woo Plugins.

Works as intended. Plugin has responsive team behind development.

For 6 years this plugin limited clients to two units of my sample size product to prevent a loss leader from turning into a plain old loss. Just updated it today and several hours later someone ordered 12 units. Had to cancel the order, which means they probably won’t be back because they’ll be offended. I knew I should have left it alone…

El plugin funciona perfecto. Sin embargo no es compatible con la opinion “High-Performance” de Woocommerce y he tenido que desactivarlo, una lastima.

I love this plugin! It’s simple, it works and unlike other WooCommerce plugins, there are no upsells whatsoever!

Thanks for this plugin. We use it along with WP Job Manager and WooCommerce Subscriptions. It ensures that our users can only purchase one subscription plan. Before, we faced the issue that a few users accidentally purchased a plan twice. Thanks for investing your time. 🙂 Florian
