Configuring complex customized quotes has improved flexibility but still needs smoother approvals
There are many out-of-the-box features available in Conga CPQ compared to other CPQ systems, and we can easily customize the entire CPQ itself using many customizations and APIs that are not available in other systems. Out-of-the-box APIs are the best features that Conga CPQ offers, as everything can be customizable. The product bulk loader is a feature that has helped my team significantly. For instance, in other CPQ systems, implementing similar features requires extensive customization. However, with Conga CPQ, using the Add Multi-Prod API, we only need a CSV file with product codes and quantities. We check for any active price list items and prepare a wrapper class to input data to that API, which simplifies creating a cart with products. Conga CPQ positively impacts my organization with many ongoing projects involving its features. People appreciate its extensive features and the support from the Conga team, who respond immediately to any cases we raise.

I like the assignment management and contact management features. I would like them to extend the possibility for functional segregation.
Extending the possibility for functional segregation would allow us to decentralize certain functions between different areas. In our organization, the administration of users (or executives who access the system) is done by an area. The management of executive skills is performed by another area, according to the current Siebel. These roles should not be independent.

Pros

"Conga CPQ offers the best features, particularly pricing, allowing me to achieve complex pricing with ease, such as using the totaling callback and base price callback."
"There are many out-of-the-box features available in Conga CPQ compared to other CPQ systems, and we can easily customize the entire CPQ itself using many customizations and APIs that are not available in other systems."
"For complex pricing and orders, if organizations want more efficiency and error tracking, Conga CPQ is a strong choice."
"As far as CRM's go, it's a very flexible solution, and we're able to customize the business rules with code and to integrate it with middleware applications to manage the rules externally."
"It provides end to end customer management, from marketing all the way to support, meaning you also have sales, product management, literature, asset management, opportunity analysis, maintenance SLA compliance, and support, with all the common features present on modern CRMs including phone sync and email merge capabilities."
"Data migration, data deduplication, and application flexibility with respect to business rules are valuable features."
"Being a single source of information, this provides an authoritative source of information."
"I found that this product had the ability to meet our business needs."
"With the implementation of the assignment manager, we are now able to automate assignment rules that we previously had in hard, and this feature allows us greater flexibility when incorporating new assignment rules."
 

Cons

"There are a few manual steps we need to take, such as handling a complex approval process in Conga CPQ."
"After converting to Conga LP revenue life cycle platform, we identified several areas for improvement. We run into more sync issues and data synchronization problems."
"However, I am currently facing many difficulties with data synchronization, and it has several loopholes not working as expected in Turbo, such as validation callbacks working fine in Turbo but failing in RLP."
"There were issues, mostly due to the lack of capability of the implementation partner who delivered the solution."
"Deployment is still considered cumbersome and the integrations are quite an expense."
"It is a very expensive product and data steward module is very complex."
"The initial setup was complex. The degree of parameterization required for the initial setup was not made obvious."
"Business rules for data duplication can be improved."
"Pricing is very high."
