Billing Management: #3 Billing Unbilled Charges Periodically

Billing Management: #3 Billing Unbilled Charges Periodically


We had a smooth sail into Prorated Billing, a practice that ensures fairness when customers join, upgrade, or downgrade a service at any point during the billing cycle. But what happens when a customer requests additional limits or features during the cycle? Sending out a new invoice for each change would disrupt the billing cycle and create unnecessary confusion.
​
This is where unbilled charges become a deal breaker. Unbilled charges record the value of service consumed or upgrades applied during the cycle without immediately invoicing the customer. Instead, these charges are a running balance that will be added to the customer's next scheduled invoice. This allows businesses to keep a clean and consistent billing cycle while ensuring all customer amendments are adequately captured.

As many industries rely on recurring or consumption-based billing models, unbilled charges are a vital mechanism for tracking ongoing usage. Let's explore how they play out across different sectors.

Telecom  
In telecommunication, services are consumed continuously, but billing happens over time. Most postpaid service bills follow this method of billing. For instance, a customer with a plan that includes 10 GB of data may exceed their allowance. If they use an additional 2GB at $5 per GB, that customer generates $10 in unbilled charges. These charges accumulate invisibly during the cycle and appear on the next invoice, alongside their monthly subscription. Similarly, charges like roaming, pay-per-view and international calls are all tracked as unbilled until the cycle closes.

Utilities 
Electricity, water, and gas are in a similar situation due to the lag between consumption and billing. These utilities are charged based on their consumption rate and the slab they belong to. Consider a household with an electricity rate of $0.12 per kWh. By mid-month, the household has consumed 250kWh, equating to $30 in unbilled charges, even though the official invoice won't arrive until the end of the month. The service provider records the consumption internally as unbilled revenue, ensuring no usage goes unaccounted for.

SaaS 
Unbilled charges often arise in Saas for usage-based or hybrid pricing models. The usage is tracked and added as unbilled charges periodically. A customer on a $100 per month base plan decides to upgrade to the $200 plan halfway through the billing cycle. The system calculates a prorated charge of $100 for the remainder of the cycle. Instead of sending out a separate invoice right away, the service provider decides to record this as unbilled. It remains pending until the end of the billing cycle, when it will be added to the customer's regular monthly invoices. By doing this, the company ensures the billing cycle remains intact, avoids confusing customers with multiple mid-cycle invoices, and protects its revenue.

Transportation & Logistics 
Transport companies, especially those serving large shipments, both in terms of quantity and quality, often consolidate usage into a single invoice. Imagine a company making 50 travel bookings monthly, each costing $20. The total $1000 in unbilled charges accumulates as the trips are completed. Instead of invoicing after each ride, the travel agency waits until the billing period ends, offering convenience for the customers and administrative efficiency for the company.

Advertising Platform 
Marketing agencies and Digital ads rely heavily on unbilled charges because campaigns run continuously. Suppose an advertiser runs a pay-per-click campaign at $1 per click, generating 500 clicks in a week, which equates to $500. These charges accrue daily but won't be billed until the advertiser hits a billing threshold, say $2000, or the monthly billing date arrives. This approach ensures uninterrupted campaign performance while keeping billing predictable.

Stretch Across with Zoho 
With the volume of transactions each of these businesses handles, manually tracking unbilled charges will be challenging. This is where a modern billing system like Zoho Billing adds value. Zoho Billing automatically computes unbilled charges based on the data provided, whether it's extra data, additional API calls or incremental ad spend. Businesses can decide whether to,
  • Invoice immediately by charging customers for accumulated unbilled charges at any point during the billing cycle.
  • Consolidate automatically by letting Zoho Billing roll all unbilled charges into the customer's next billing date.
 
For instance, if a SaaS customer exceeds their plan by generating $300 in API consumption, the service provider can either issue a one-off invoice on any given day or allow Zoho Billing to add the charge seamlessly to the upcoming monthly bill. This flexibility reduces revenue leakage, improves cash flow, and enhances transparency to the customers.

By automating unbilled charge invoicing, Zoho Billing ensures that no consumption unit is lost. At the same time, businesses retain the freedom to charge customers in real time or on their preferred billing schedule.

Up Next
​With prorated billing ensuring fairness and unbilled charges providing completeness, the next billing in line is Advance Billing. Unlike unbilled charges, where usage is billed after the fact, advance billing collects payment upfront before services are rendered, ensuring cash flow and reduced payment risk.

This model has advantages and challenges. Our upcoming post will examine how advanced billing works and the businesses that can adopt it.
