Apart from increasing the bottom line and slashing the sales cycle to half, Salesforce CPQ will give your business a lean selling capability. Processes like submitting proposals and delivering quotes will be streamlined for good, reducing time and resources waste, AND zero stalling of the sales pipeline due to any unforeseen circumstances.
BUT, merely having Salesforce CPQ deployed is not going to troubleshoot all your sales woes, to make the most of the Salesforce CPQ ecosystem we need to customize options, features for configuration of every business vertical to increase quote accuracy and effectively upsell/cross-sell.
Salesforce CPQ includes a Configurator but here we will explore scenarios, wherein a use case requires a custom app, component, or even an external software to offer complex services or products.
