🔍 1. Exploring the Benefits of QCP in Salesforce CPQ

Let’s be honest — out-of-the-box solutions don’t always cut it. That’s where QCP shines.

Think of QCP as your backstage pass to control how quote calculations work — from tweaking field visibility to dynamically controlling field editability based on business logic.

✨ Why Use QCP?

• Dynamically hide/show fields in the quote line editor
• Enforce complex business logic not possible through standard CPQ configuration
• Execute calculations at different stages of the quote lifecycle
• Improve performance by reducing unnecessary rule executions

QCP gives developers surgical control over the quote calculation process. It’s a game-changer for businesses with sophisticated pricing models.

Exploring the Benefits of QCP in Salesforce CPQ

Elevate your quote line editing experience in Salesforce CPQ by harnessing the power of custom JavaScript code. With seven dynamic methods at your disposal, you can redefine calculation processes. These processes fit your unique pricing strategies. You can also enhance page-level security to tailor field visibility according to specific user roles. Imagine implementing complex discounting logic. Make certain sensitive data remains hidden from unauthorized users. Create a seamless workflow that adapts to your business needs. All of this is possible through the capabilities of QCP. Transform your quote management into a streamlined, efficient operation.

QCP JavaScript: Syntax and Its Supported Versions

If you’re comfortable with JavaScript, you’re already halfway there — QCP uses ES6 syntax, which means it feels just like writing modern JavaScript. No weird learning curve. Just smooth, familiar coding. 😎

Now, what exactly is QCP?

Quote Calculator Plugin (QCP) is like a backstage pass to Salesforce CPQ’s quote calculation engine. It gives you special hooks—little doors where you can insert your own logic during different steps of the quote process.

Want to hide or show fields based on user input? ✅
Need certain fields to be read-only for specific products? ✅
Want to add your own calculations on top of what Salesforce already does? ✅
QCP’s got your back.

With just a few lines of JavaScript, you can control how quote lines behave, look, and respond—all in real time.

So yes, you’re ready to dive in and start building smarter, faster, and more dynamic quoting experiences! 🚀

Here’s a breakdown of a basic QCP script and what each part does:
🔹 onInit
This function runs when the Quote Line Editor is initialized. It’s a good place to perform any setup logic before calculations begin.
👉 In this example, it’s empty but can be used to set default values or prepare data.

export function onInit(quoteLineModels) {
  return Promise.resolve();
};

🔹 onBeforeCalculate
Executed before any pricing rules or custom calculations happen.
👉 Use this to adjust values or quote line items before calculation starts.

export function onBeforeCalculate(quoteModel, quoteLineModels) {
  return Promise.resolve();
};

🔹 onBeforePriceRules
Called just before the pricing rules are applied.
👉 Ideal for making any final adjustments before Salesforce CPQ logic kicks in.

export function onBeforePriceRules(quoteModel, quoteLineModels) {
  return Promise.resolve();
};

🔹 onAfterPriceRules
Fired immediately after pricing rules have run.
👉 Use this to inspect results or apply further changes post-rule execution.

export function onAfterPriceRules(quoteModel, quoteLineModels) {
  return Promise.resolve();
};

🔹 onAfterCalculate
The final step—executed after all calculations are done.
👉 Good for validations or UI-based changes based on calculated values.

export function onAfterCalculate(quoteModel, quoteLineModels) {
  return Promise.resolve();
};

🔹 isFieldVisible
Controls the visibility of fields on the Quote Line Editor.
👉 Here, the SBQQ__Description__c field is hidden from the UI.

export function isFieldVisible(fieldName, quoteLineModelRecord) {
  if (fieldName == 'SBQQ__Description__c') {
    return false;
  }
  return true;
};

🔹 isFieldEditable
Manages whether fields can be edited by the user.
👉 In this case, the same SBQQ__Description__c field is made read-only.

export function isFieldEditable(fieldName, quoteLineModelRecord) {
  if (fieldName == 'SBQQ__Description__c') {
    return false;
  }
  return true;
};

🧠 Quick Breakdown:

• 'onInit‘, ‘onBeforeCalculate‘, ‘onBeforePriceRules‘,… etc., are lifecycle hooks.
• These functions allow you to plug in your custom logic before/after Salesforce CPQ runs its native logic.
• ‘isFieldVisible‘ and ‘isFieldEditable‘ control UI behavior dynamically.

⚠️ Important: Salesforce supports ES6 (ECMAScript 2015) features in QCP scripts. Stick to supported syntax to avoid runtime errors.

🎯 Wrapping Up – What’s Next?

In this blog, we set the foundation by understanding why QCP is useful and how its syntax works. But this is just the beginning!

🚀 In the upcoming posts, we’ll go deeper into:
