We have introduced Pay what you want feature app within the Multivendor Marketplace App for Shopify.

Pay what you want (PWYW) also known as Value-for-Value model is a pricing strategy where buyers pay their desired amount for a given commodity.

A minimum (floor) price is set, and/or a suggested price may be indicated as guidance for the buyer.

Pricing: This feature will have an additional charge of USD 10 per month over & above your current Multivendor Marketplace plan charges.

Let's move on to the installation & configuration process!

Enable the following app by visiting:

• Multi-Vendor Admin Panel
• From the Dashboard, hover over the three dots on the top-right of the page
• Click on Feature Apps

To add a product, visit Multivendor Marketplace Admin/Seller Panel > Products > Product Listing > Add Product.

Now, while adding the product, you need mark product as Pay what you want Product.

Other than this, add a minimum price to the product, enter the rest of the details and save.

The "minimum price" can be added in two ways i.e, fixed and percentage. You can opt this from product configurations:

Note:

The normal products can be converted into PWYW products and vice-versa.

Also, on the seller profile page, the prices for PWYW products don't display. If you want to display them, add the following code to the seller profile theme:

    {if $pay_what_you_want_active && $value.type == 7} hidden {/if}

Moreover, after adding all the codes, this is how the frontend will look like:

If a customer tries to checkout after entering a price lesser than the minimum amount set from the backend, he will receive a message saying:
"You must pay at least *minimum amount value*"

This is all about the Pay What You Want feature app.
