What is the best "Product Add-on" plugin integrated with B2BKing?

Hi Stefan

Can you help me to get the best Add-ons plugin in terms of its integration with B2BKing?

I read two options that you posted in some answers in this Forum (one for B2Bking and the other for MarketKing)

1-  https://support.kingsplugins.com//ticket/3769822/ 

• WooCommerce Product Addons 
• Plugin Republic’s Product Addons Ultimate 

      These plugins are integrated with MarketKing

ThemeComplete is actually the best integrated so that's the one we would suggest. The integration is not perfect but most functionalities should work.

For this to work correctly, you would usually need to enable the setting in B2BKing -> Settings -> Other -> Product addons compatibility: https://prnt.sc/wfauxYYMm0iE

I bought a Lifetime license of the plugin

but unfortunately the integration is far from working, I can assure you that it doesn't work.
The right thing to do was to first consult you, which is what I'm doing now.

And the truth is, what I'm looking for is researching a way to be able to sell a product by unit, and then after a specific quantity (for me it's 10) from there, the quantity is converted into a step of 10 units, which is the box, and the price goes down.
I don't want to sell, for example, 12 units, for that quantity the customer pays 2 units in a line in the cart, and then for a box with its price benefit per box and that adds another line in the same cart.
I suggested that type of STEP to you once, and I'm trying to achieve it with an odd-ons plugin, let's see if I can.

Thanks and greetings.
