Hello,
From speaking about the traditional ways of billing in the previous post, we are moving into the deep sea of billing. We are now in a zone to break out the most complex yet, I would call it the fairest way of billing, the Prorated Billing.
Prorated Billing ensures that customers pay only for the exact portion of a service they consume. Whether they join mid-cycle, switch plans, or cancel early, proration guarantees transparency and fairness.
What is Prorated Billing?
In short, prorated billing involves splitting charges according to the length of service used within a billing cycle. Instead of charging the customer for the entire month regardless of when they sign up or amend the subscription, businesses calculate charges accurately based on time or usage. This directly enhances customer trust and satisfaction and eliminates disputes over charges.
In this post, we will understand how proration works in different industries by examining the major industry types that need/must have proration in their billing strategy.
Scenario: SaaS
A SaaS customer starts the month on the Basic plan, which costs $30/month. Midway through the billing cycle, on the 15th, they realise they need additional features and decide to upgrade to the Pro plan, which costs $60/month.
Without proration, businesses might charge the full $60 or keep them on Basic until the next cycle, which is unfair. With proration, this can be solved by splitting the bill into the part that will be used and the period that has elapsed.
In this scenario, part of the month is charged at the Basic plan cost, and the remaining is charged at the Pro plan cost.
Old Plan | New Plan |
Basic Plan: $30 | Pro Plan: $60 |
Charges per day: $30/30=$1 | Charges per day: $60/30=$2 |
No.of days remaining: 15 | No.of days to be charged: 15 |
Credits Remaining: $1x15=$15 | Amount to be charged: $2x15=$30 |
Net Payable: Amount to be charged- Credits Remaining: $30-$15= $15 |
The Final Invoice Amount must be charged on the 15th, and the customer's subscription will be moved to the Pro Plan.
Scenario: Telecom
Imagine a customer activating a mobile plan costing $60 on the 20th of the month. The company has a standard billing cycle of 30 days. Some businesses might activate the plan for the full plan amount and allow it to be charged again on the set billing cycle. However, that's not the ideal approach.
With Proration, the days before the activation date are excluded, and charges are made only for the exact number of days used.
Plan Amount: $60
Charge per day: $60/30= $2
No.of days to be billed: 10
Final Payable Amount: $20
The Final Payable Amount will be charged on the plan activation date, and the next charge will occur after 10 days, aligning with the billing cycle.
Scenario: Streaming Service
A streaming subscriber who is active in the $120/month Premium plan decides to switch to the $60/month Standard plan after 10 days of usage in the current billing cycle.
Without proration, the customer might feel overcharged for unused Premium days. So, to balance the charges between the higher-priced plan and the lower one, credits will be added to the customer account, which can either be refunded or adjusted for the next invoice cycle.
Old Plan | New Plan |
Premium Plan: $120 | Standard Plan Cost: $60 |
Charges per day: $120/30= $4 | Charges per day: $60/30= $2 |
No.of days used: 10 | No.of days remaining: 20 |
Charges for used days: $4x10= $40 | Amount to be charged: $2x20=$40 |
Remaining Credits: $80 | |
Net Credit: Remaining Credits- Amount to be charged for 20 days: $80-$40= $40 |
The Net Credit will stay with the customer account and will be applied to the next invoice, or it can be refunded.
Proration Across Industries
While SaaS, Telecom and Streaming services are the most common businesses where prorated billing happens quite often, other industries need this,
Logistics Companies operate with standard shipment charges. They might need proration when the volume of the consignment changes in the middle of the cycle.
Internet Service Providers use this when there is a change in plan within the billing cycle.
Fintech and Payment Apps prorate service fees when accounts are opened or closed in the middle of the billing cycle.
Zoho Billing has the finesse to handle these contract amendments effortlessly across industry types. Whether it's a mid-cycle upgrade, a partial cancellation, or a new customer subscribing during the middle of the billing cycle, Zoho Billing ensures invoices are adjusted seamlessly. Proration can be enabled in Zoho Billing with a simple toggle, and the application automatically takes care of all the math in the backend.
Proration Billing is not a burden but a gift wrapped in a hard cover.
Offering fair charges based on usage during billing increases confidence and provides businesses with a reputation for being fair and transparent. But what about usage that happens before it hits the bill? Even with proration in place, there are scenarios where usage happens before it's billed. For instance, a customer may request an add-on, consume additional resources, or make a one-time transaction in the middle of the billing period. These often fall into the category of unbilled charges.

In the next post, we will explore how businesses manage these unbilled charges and why keeping them in check is critical for accurate billing.
