How to Automate EV Charging Billing in Salesforce

With the rise in EV adoption, parking operators are scaling up their EV charging networks faster than ever. 

As the number of chargers and users increases, billing quickly becomes more complex. 

Manually processing charge sessions, applying tariffs, and chasing payments slows down operations and limits growth. 

If you're using Salesforce as your CRM or billing platform, there’s a more efficient way to manage EV charging billing. 

This article shows how to automate the entire billing flow using Salesforce tools like CPQ and custom objects. You’ll get a clear structure for mapping billing logic and building a scalable automation setup. 

For a full technical overview, including architecture diagrams and connector capabilities, explore our Salesforce EV Charging Integration guide. This post focuses on how the billing process works in practice. 

Why EV charging billing needs automation in Salesforce 

EV charging billing is event-based.  

Each charge session generates its own data: how long the driver stayed, how many kilowatt-hours they used, where they charged, and under what pricing rules.  

Multiply that across hundreds of sessions per week and you’re looking at hours of manual effort. Unless it’s automated. 

Salesforce already handles customer relationships, invoicing, and revenue reporting. Bringing EV charging data into this environment unlocks real billing automation: 

• Pricing rules apply automatically 

• Invoices generate on a schedule 

• Customer records stay in sync 

• Roaming sessions are accounted for 

• Revenue reporting is always up to date 

With the right setup, Salesforce becomes the core of your EV charging business, from session to settlement. 

What data needs to flow in for billing to work 

Accurate billing depends on clean, structured data. These are the essentials: 

• Charge session data: Timestamp, kWh consumed, session duration, charge point ID 

• Tariff logic: Public price, customer-specific discounts, VAT rules 

• Customer identity: Driver ID, B2B fleet account, roaming partner name 

• Product classification: Session type (AC, DC, fast charge), SKU mapping 

• Location details: Site ID, pricing zone, operator account 

When this data arrives in Salesforce in real time, it allows the system to apply pricing rules, generate billing records, and trigger invoicing.  
 
The best part? It does that without anyone lifting a finger. 

The object model that makes billing automation work 

Salesforce is flexible, but you need the right structure to make billing flow smoothly. Here’s a simple object model tailored for EV charging: 

• Custom Object: Charge Session - Stores each session's core data: start/end time, kWh, price, charge point, driver ID 
   

• Standard Object: Product - Defines what was sold. For example: "Urban Charging Session", "Fast DC Charge" 
   

• Standard Object: Price Book - Allows different tariffs by customer group, region, or time 
   

• Standard Object: Account - The customer or roaming partner 
   

• Standard Object: Quote - Generated automatically based on the billing period and usage 
   

• Standard Object: Quote Line Items - Each line represents a charge session or a batch, with all pricing logic applied 

This structure keeps billing data tied to customer accounts and pricing rules, while enabling CPQ automation and invoicing workflows. 

Automating the process with Salesforce CPQ 

Salesforce CPQ works well for metered usage like EV charging. Operators use it to streamline EV charging billing through automation and clear rule logic. 

Here’s what’s possible: 

• Automated quote generation on a recurring schedule 

• Dynamic pricing rules based on time of use, charger type, or customer group 

• Volume-based discounts or surcharges applied at the quote stage 

• One-click invoice conversion for fast revenue processing 

• Batching of sessions into billing summaries for fleet or roaming accounts 

These rules are built using standard CPQ features. Once charge session data flows into Salesforce, quotes generate automatically and move directly into invoicing. 

Where the eMabler Salesforce Connector fits in 

Billing automation in Salesforce depends on accurate, complete, and real-time charge session data. 

The eMabler Salesforce Connector makes that possible. 

It links your EV charging infrastructure to Salesforce using secure APIs. It transfers session data with full context (driver ID, charge point, pricing model, and location) and maps it to your custom objects.  

Whether you're running your own chargers or managing roaming traffic, the data stays consistent and up to date. 

With the connector in place, you can: 

• Sync charge sessions instantly into Salesforce 

• Apply pricing logic and CPQ rules automatically 

• Generate quotes and invoices without delay 

• Track revenue by site, account, or service type 

• Scale your operations without extra manual work 

There’s no need to build or maintain custom integrations. The connector fits your business setup and grows with it.
