SAP SALES CLOUD&CPQ

We plan to go live with SAP sales cloud&CPQ at the beginning of June 2022. Our main problem is the sales order management side. Because our process is starting CRM (potential customer, activities, opportunities, etc). Then if our customer requires our products that means trailer, we convert opportunities as offers and click as won. Secondly, we can select sales offers inside the opportunity screen. Then we create an offer (quotation). When our customers accept our quotation, we can select the quote won and send this offer to the SAP ERP system. But when we can select quote won selection, we can create sales orders in C4C sales or CPQ system. And we want to manage sales order features in the C4C sales could or CPQ system. Because we have different processes for sales order management. For examples sales revision process, Sales retrofit process, Sales trailer logo process, sales addendum print out process, sales special retrofit request process, etc... And also, the other main problem is that the C4C sales and CPQ are running so slowly. When we configure a new product on the CPQ system, the system performance is so bad. And so much slower. I know that when we use it in real business life. our sales guys will complain about system performance.
