Billing Management: #6 Usage Billing in SaaS

Billing Management: #6 Usage Billing in SaaS

Imagine a customer shuffling across multiple subscriptions, a streaming service, a music app, cloud storage, and a design tool. Each one charges a flat monthly fee, regardless of how much or how little they use. Some months, the customer barely opens the subscriptions, yet the bill is the same. This is what we call subscription fatigue, meaning resistance from the customer towards fixed, recurring charges that don't match their actual usage.   

For SaaS, subscription fatigue is more than a buzzword. It's a business risk as a flat rate may appear overcharging for one, but others enjoy paying less for their high usage. This imbalance leads to churn, lost revenue and customer grievances.

The solution lies in usage billing, where the customer pays based on what they consume. By aligning cost with value, businesses can increase fairness and unlock sustainable growth. While the principle is simple, it requires a reliable way to track and monetise usage properly.


Zoho Billing Makes Usage Billing Seamless

Zoho Billing provides SaaS businesses with all the tools needed to implement usage-based pricing effectively. Key capabilities that Zoho Billing offers that work effectively for SaaS businesses include:

  • Flexible Pricing Tiers: Businesses can create multiple plans with different prices and list them on their websites for direct signup.

  • Zero value Plan: For charging customers purely based on usage alone, businesses can create $0 value plan and associate usage addons to charge appropriately.

  • Addons: Attach both flat-rated addons and usage-based addons to the subscription.

  • Hybrid Model: Combine a flat subscription fee with usage-based addons to monetise additional consumption fairly.

When a usage addon is attached to a subscription, Zoho Billing ensures that usage is tracked, recorded and billed accurately.


Scenario 1:

Sam runs a small consulting firm and uses a mailing application to communicate with his clients. His plan costs $200 and includes 500 GB of storage. Sam stays within the limit most months; however, with many attachments, proposals and reports during a particular month, his mailbox usage exceeds by another 100 GB. The mailing application provides a usage addon for $0.50/GB for the additional usage instead of offering a rigid higher value plan.

The billing team records the extra 100 GB usage in Zoho Billing using the manual usage entry method and nothing more. The system automatically calculates $50 overage fee and appends it to the invoice to make the renewal invoice for the period $250.

Scenario 2:
Imagine Smith Enterprise uses a cloud analytics SaaS product. The contract covers a base subscription plan and two usage add-ons: API calls and storage. The base plan costs $500/month and includes 100,000 API calls and 500 GB storage. For every API call they make, an extra $0.01 per call will be charged. Similarly, for extra storage, $0.10 will be charged per GB. 

During a particular month, the company consumes 250,000 API calls and 750 GB of storage, clearly above the usage limit. A subsequent invoice is created, and the charge based on the usage data is added to the base subscription value.

The company exports the API call logs and storage usage data into a CSV file that can be imported into Zoho Billing. Zoho Billing digests both records, applies the pricing rule separately for each add-on, and generates a consolidated invoice.

Scenario 3: 
Roy runs a digital marketing agency offering various marketing campaigns across social media platforms. Roy owns a SaaS application that generates posts and charges $1.5 per post design. No fixed base price for this, but their clients are purely charged based on the number of posts made. During festive sessions, Roy's team schedules a maximum of 450 posts for a client.

Using Zoho Billing, Roy records the usage manually or by importing them into the system. With no base price, the platform automatically calculates the total invoice based on the usage. Roy receives a clear invoice for $675, reflecting the value consumed.

SaaS Usage Billing Simplified

Usage Billing ensures that customers pay only for what they consume, whether extra storage, extra API calls, or purely based on the number of posts made. With Zoho Billing, SaaS businesses can seamlessly manage complex and straightforward usage billing scenarios. Adding usage to Zoho Billing is simplified through different methods. It can be added manually if there are fewer subscriptions, and usage data can be imported if there are more subscriptions and usage add-ons. Usage can also be pushed using APIs into Zoho Billing.
