Mocy Bell review for Ymq B2B & Wholesale Solution
March 11, 2026
We installed this app to manage B2B pricing on a Shopify store selling across Europe. Unfortunately, there is a serious issue with discount recalculation during checkout. The app applies B2B pricing using a discount. The discount is calculated correctly at first, but when Shopify updates the product price during checkout (for example when the customer changes the shipping country or enters a valid EU VAT number), the discount does not recalculate. As a result, the final price becomes incorrect. Example: France → product price 26.90 €, discounted price 7.68 €. Customer changes country to Portugal → Shopify updates the product price to 27.58 €, but the discount remains based on the original price. The developer confirmed the issue but said they do not plan to fix it. Because of this, the app is not reliable for EU stores using Shopify Markets, VAT changes, or VAT-exempt B2B customers.
Hi, Thank you again for your message, and I apologize for the delayed response. Recently, most of our development resources have been focused on building our upcoming **B2B V2 version**, which is designed to make the system more flexible, powerful, and easier for merchants to configure complex pricing logic. Because of this, our response time may not have been as fast as usual. Regarding the issue you described, the current behavior is related to how B2B pricing is typically implemented on Shopify. Our app applies B2B pricing using draft orders. Once the draft order is created and the customer enters the Shopify checkout, third-party apps are no longer able to execute code or modify pricing. If the customer changes the shipping country or VAT status during checkout, Shopify may update the product price based on Markets or tax rules, but apps cannot recalculate discounts at that stage. It is also worth mentioning that the majority of B2B apps on Shopify rely on draft orders in a similar way, which means they are subject to the same platform limitations. The only potential technical direction to address this type of issue would involve using **Shopify Functions** provided by Shopify. However, Shopify Functions currently have strict limitations on input and output size, execution time, and overall computational complexity. Because of these constraints, we cannot yet confidently confirm whether a stable solution is feasible for this scenario. What we can say is that as part of our ongoing V2 development, we will continue to evaluate whether there might be a viable approach to handle cases like this in the future. This is not a situation where we simply do not want to fix the problem. When building on top of the Shopify platform, some capabilities are constrained by the APIs and infrastructure that Shopify provides. For the specific scenario you described, the technical difficulty is quite high, and it requires careful evaluation. Thank you again for your feedback and for bringing this case to our attention.
