Shopify Discount App

Hello,
Hope you are doing well.

I have a shopify store with 6000+ products.

We need to install an app for B2B in order to create discounts per category and shipping per category.

We already tried the following apps but they did not work :

Spark Layer Shopify app - by far one of the most popular -https://apps.shopify.com/sparklayer?surface_detail=spark+layer&surface_inter_position=1&surface_intra_position=4&surface_type=search

Bold custom pricing app - https://apps.shopify.com/customer-pricing

Charge me Later wholesale app - https://apps.shopify.com/charge-me-later

Volume & Discounted pricing app - https://apps.shopify.com/custom-pricing-discounts-by-appikon?surface_detail=volume+%26+discounted+pricing&surface_inter_position=1&surface_intra_position=4&surface_type=search

We can add Shopify plus but it’s too expensive,

So can you please send a list of apps according to my project, your cost and time?
Once I find the best app that you will send, I will add you and let you work on it.
Give your price.


Thank you
