The number #1 Van der Meer WooCommerce plugin

Import and synchronise thousands of premium pet supply products from Van der Meer to WooCommerce with this WooCommerce plugin. The import includes images, description, attributes, categories, stock, price and many more.

How to import products

  • Select which product categories you would like to import from Van der Meer to your WooCommerce store.
  • Include or exclude certain SKUs.
  • Apply import filters based on product stock and price.
  • Define your desired price margin based on a percentage, fixed amount or advise price.
  • Automatically synchronise stock and price every 30 minutes.

Configure all plugin settings to your needs

  • Send orders automatically for dispatch to Van der Meer.
  • Import products as draft so that you can customize the products before publishing them to your WooCommerce store.
  • Trash unavailable products to prevent a 404 page appearing in search engines.
  • Import product variations if you want products to be imported as variable products in WooCommerce.
  • Only import products from a minimum and maximum purchase price.
  • Exclude products from the import that are out of stock at Van der Meer.
  • Round up your sale price from 20.17 to 20.25, 20.99 or 21.00.
  • Choose whether or not to override price, title, description, short description, weight, attributes and categories.

Auto-synchronise products

The product stock and price will be updated every 30 minutes. Other product parameters, such as: title, description, categories and attributes can be updated optionally. You can enable or disable them via the plugin settings in the Synchronization tab -> Product information.

Dispatch orders automatically

  • Customers will order products and pay you
    The order can be automatically send to BigBuy. You will pay BigBuy the purchase price and it will dispatch the order to the customer from your name. The profit between sale price and purchase price, is your margin.
  • Track & Trace codes will be shared
    BigBuy will provide a Track & Trace code, which will be imported to the WooCommerce order. You can include this in the WooCommerce email and send it to your customer.
  • Returns and refunds
    BigBuy does not have a solution for returns. As a webshop owner, you are responsible for accepting returns and submitting refunds.

What do you need?

Additional recommendations

Our plugin requires serious resources. The Van der Meer WooCommerce plugin will not only import products, but will also update stock and price every 30 minutes. A cheap shared hosting plan, will not do the trick. This will cause the update task to pile up, meaning stock and price will be updated with a big delay or even get stuck.

If you’re not sure, you can consider moving your hosting to Woosa. Explore our WooCommerce hosting plans here.

How many products can I import to WooCommerce?

BigBuy has a product catalog of 100,000+ products and variations. Theoretically, you can import all these products. On average it will take 24-72 hours depending on your server resources. However, most customers we service don’t have enough server resources for such a big number of products. That’s why we mostly advise to maximize up to importing 50,000 products.

How often will the stock and price be updated?

The stock and price will be updated by Van der Meer every 30 minutes, so will our plugin. However, if the impact of the change of stock is minimal (e.g. 168 to 164) we will not update. Simply to not burn out your server resources, for unnecessary changes.

How are returns managed?

It depends on the agreement you have with Van der Meer, whether or not they take returns in your name. If not, you should handle returns and refunds yourself.

Is this plugin entirely for free or do I need a secret pro version?

This plugin is completely free and there is no secret pro version necessary or available. We believe in enabling starting entrepreneurs, by offering them premium plugins. However, the free version only provides support via our Woosa Community on Discord. If you want or need more in-depth support, we would like to advise you to check our support plans.
