Buyer’s Overview

An adaptable SaaS billing engine isn’t just a tool for finance—it’s a strategic advantage.

In a recent webinar where we hosted Mountu Jinwala, who built billing systems for Netflix and eBay, he emphasizes:

Fast, precise SaaS billing is critical for monthly financial reporting, as most companies have as little as three days to prepare the reports. That’s why accurate SaaS billing systems are essential for reducing reliance on engineering teams (allowing internal stakeholders to manage billing adjustments independently), streamlining processes, and eliminating common billing errors.

  • Offers simple invoicing
  • Support for multi-currency and tax calculations available 
  • Self-service portal for customers to manage subscriptions, view invoices, and update payment methods
  • Supports discounts, credits, and free trials

Pros

  • Supports multi-currency and basic dunning features
  • Robust API and extensive developer documentation
  • Revenue recognition module is a separate product from its billing platform

Cons

  • Reliable for processing payments, but it doesn't offer a native CRM integration
  • Its compatibility with payment methods outside its ecosystem is reportedly inefficient
  • It lacks the ability to customize invoice templates and automate SaaS invoicing for complex pricing models
  • It doesn't support detailed reporting on SaaS metrics
  • It requires external tools or manual processes to manage RevRec
  • Email support is slow, which can be frustrating for businesses that need quick resolutions to urgent billing issues

  • Entitlements and trial management 
  • Automates basic dunning and revenue recognition
  • Secure zero-code checkout

Pros

  • Automates tax calculations
  • Accepts payments in 100+ local currencies
  • Email support is available to all customers
  • Comprehensive reporting on SaaS metrics
  • Integrates with popular third-party apps

Cons

  • Supports a limited range of payment methods and currencies, which may limit its suitability for international operations
  • Transitioning between product families can cause data loss and invoicing issues, reducing flexibility in managing different access levels
  • Invoicing features are rigid, with limited options for template customization and restrictions on editing line items or consolidating invoices
  • Reporting capabilities need improvement when handling large datasets 
  • Chargebee supports limited payment methods, so custom integrations are required for some gateways
  • Integrations with NetSuite and Salesforce come with extra costs
  • Its CRM integration could be more efficient, often requiring manual work to sync data.
  • Live chat and callback options are exclusive to paid plans only

Pricing:

Chargebee's pricing can become expensive as your business scales. It starts at $599/month for up to $100k in monthly billing and then adds a 0.75% fee. While a free plan is available for startups with early traction, the cost can escalate due to add-ons. Furthermore, self-driven sandboxes are only available on the Performance and Enterprise plans.

4. Maxio

Maxio is best-suited for PLG SaaS companies with simple usage-based pricing models. It can handle simple usage-based models like tiered, stair-step, events-based, and metered billing. However, it requires engineering bandwidth to work with complex pricing. It only supports complex UBP scenarios like wallet-based transaction options and hybrid billing, limiting its scalability for sales-led SaaS companies.

Features

  • Public sign-up pages and self-service billing portals for easy customer onboarding
  • Supports both sales-negotiated contracts and self-service subscriptions
  • Effortlessly ingest usage data via APIs or CSV uploads to ensure precise billing
  • Configure and manage promotional discounts, special offers, and custom pricing structures
  • Automate subscription management, including signups, renewals, plan modifications, and cancellations
  • Multi-currency and multi-entity capabilities 
  • Customizable dashboards to track key business metrics 

Pros

  • Seamless integration with leading payment gateways
  • Allows the creation of unique subscriptions from scratch without affecting the base prices set on catalog items
  • Automates metering
  • Generates invoices automatically for new subscriptions, renewals, prorated plan changes, and one-time charges

Cons

  • Technical support is needed to ingest more than 200k events/day, which can be a deal-breaker for companies having large transaction volumes
  • Maxio's collection features are limited to payment failure retries, and collections and dunning must be managed manually
  • Invoice emails require separate creation for each payment method
  • Payment reminders cannot be sent before the due date
  • Due to its restricted architecture, its revenue recognition is limited to vanilla subscriptions and needs a fully synced accounting system
  • Maxio's reporting and analytics capabilities are also limited, with metrics such as ARR and MRR being challenging to fetch
  • Enterprise clients receive more personalized service via a dedicated account manager, leaving small and medium businesses with limited direct assistance

Pricing:

Maxio's pricing model starts at $599/month for SaaS subscription billing with up to $100k monthly billing, after which overage fees apply. Add-ons like Account Receivables, Payments, and Metering are extra, significantly increasing costs and making it an expensive choice for many businesses. While it offers a sandbox for testing, this is only suitable for developers.

5. Zuora

Zuora is ideal for enterprise-grade PLG and SLG companies with a high volume of transactions. It supports various subscription, usage-based, and hybrid pricing models but faces limitations due to its legacy subscription-first structure. It also needs to work on inflexibility around custom payment plans though. The pricing changes require engineering bandwidth similar to Maxio, making it less adaptable to rapidly changing business needs.

SaaS billing challenges and best practices to tackle them

SaaS billing complexities require implementing best practices to address them effectively.

1. Evolving SaaS pricing

Most legacy SaaS billing tools run on archaic architecture and often lack the flexibility to adapt to modern pricing strategies such as usage pricing, sales-led contracts, or new monetization approaches, limiting a SaaS business's revenue potential.

  • Best practice: Value-based pricing supports long-term SaaS growth by ensuring customers are paying for the value received. Our co-founder, Saurabh Agrawal, caught up with Dan Balcauski, founder of Product Tranquility, in a webinar, where he suggested:

Adopt a SaaS billing platform that supports limitless flexibility and experimentation in SaaS pricing and aligns with your business growth objectives, such as expanding into new markets or customer segments.

Dan Balcauski

It should also integrate with usage-tracking systems to automate billing for fluctuating consumption without disrupting day-to-day operations or increasing engineering overhead.

"As a fast-growing business, we need a robust billing infrastructure to support growth. Zenskar's flexibilty in configuring custom contracts transformed our finance ops. Integrating with out CRM and ERP enabled efficient scaling without sacrificing accuracy or compliance. The user-friendly platform also gave our lean team full control over billing."

2. Aligning billing with your growth model

The requirements for a billing system differ significantly between product-led growth (PLG) and sales-led growth (SLG) models. A billing tool without self-serve capabilities that cannot handle a surge in customers or provide predictable software spend may hinder scalability for PLG companies. Conversely, a billing tool lacking integrations with CRM or support for complex contract configurations can disrupt the quote-to-cash process for SLG companies.

  • Best practice: Mountu Jinwala, who built billing systems for Netflix and eBay, shared tips on aligning billing with growth in a webinar with our co-founders:

If you’re running a PLG company, your billing tool must prioritize scalability and self-service functionality to align with user-driven growth. On the other hand, if you own a SLG company, your billing tool should provide seamless integrations and robust compliance support to meet the structured demands of sales-led operations.

Mountu Jinwala

3. Managing multi-currency & global sales taxes

Some billing solutions struggle to keep up with evolving tax regulations, and managing global customers adds challenges like multi-currency setups.

  • Best practice: A billing platform with built-in capabilities for regional tax compliance or integration with tax automation tools like Avalara. It should support multi-currency payments and real-time currency conversions as well.

4. Real-time reporting

Handling refunds, account credits, one-time payments, discounts, and cancellations can significantly impact the relationship between billing workflows and reporting on MRR and ARR. Delays in SaaS insights impair time-sensitive business decisions.

  • Best practice: A billing system with real-time analytics to provide actionable insights into key SaaS metrics, such as cash flows, churn, and revenue trends, ensuring more informed decision-making.

5. Manual billing processes

If you manually manage various plans, billing cycles, and adjustments for upgrades or downgrades, there are likely delays and errors. Implementing sales programs like discounts, promotions, or coupons manually using a legacy system is also costly and labor-intensive.

  • Best practice: A centrally managed and automated billing platform automates billing and sales programs by eliminating manual effort. 

Leza LeBlanc

"Invoicing hundreds of customers was unsustainable. Zenskar automated it all. We've cut month-end close time by 80% and can finally focus on strategic initiatives instead of copying data from emails."

6. Handling SaaS revenue recognition

Revenue recognition in compliance with standards like ASC 606 or IFRS 15 can be challenging if your billing system cannot distinguish between when products/services are billed and when they are delivered. Correctly accounting for revenue and recognizing it over the subscription term is essential for accurate financial reporting and investor confidence.

  • Best practice:  A SaaS billing platform that automates revenue accounting by assigning transactions and recognizing revenue in real-time. The platform should maintain audit trails, support custom recognition rules, and generate audit-ready reports while adhering to ASC 606 and IFRS 15. Beyond that, it should provide insights into revenue patterns, unlocking the full benefits of SaaS billing software.

Must-have features in the best SaaS billing software

To help you supercharge your billing workflows, we’re sharing the top 9 things that you need to keep in mind when you set out to choose a SaaS billing system.

1. Stakeholders and their needs

Typically, most organizations have the following stakeholders involved in the quote-to-cash process:

  • Sales
  • Finance/account manager/customer success
  • Collections
  • Accounting
  • Business management
  • Product and tech

It’s important to ensure that the billing system you select is solving the pain points that stakeholders in your organization are dealing with. 

  1. Sales teams

Consider how sales teams contribute to the overall billing process, from contact management to potential points of engagement throughout the billing lifecycle. Most sales teams initiate the billing process by getting contacts into the system. Ensure that the billing system that you opt for also effortlessly syncs with the tools used by sales teams to create contracts and automatically retrieves contract data from those sources. The billing system’s interface needs to be simple and intuitive, with clear navigation and control options. It should provide a hassle-free billing experience for sales teams.‍

  1. Finance/account manager/customer success teams

For the finance teams, account managers, and customer success executives, browsing through invoices and cross-checking them to ensure they are correct should be made easy. All the data from different internal systems needs to be pulled in correctly to the billing tool, empowering finance teams to effortlessly identify and resolve billing issues.

  1. ‍Collections teams

Collections become a hassle for your teams, primarily when dealing with a sizable customer base or opting for non-auto charging mechanisms. Implementing a robust receivables system is crucial to prevent overdue accounts, streamline debt recovery processes, and enhance cash flow through automated payment reminders. Select a billing system that has a seamless process in place for sending out timely payment reminders, creating a proactive approach to streamline collections and minimize involuntary churn.

  1. Accounting teams

Choose a billing system that supports advanced accounting needs. Each company uses accounting rules that are sometimes quite complex and differ in nuanced and subtle ways. The billing tool should automate the process of passing accounting entries, regardless of the complexity involved. Opt for a billing system equipped with a flexible and easy-to-configure accounting rule engine to meet your specific requirements. A billing tool that automatically generates accounting entries based on billing workflows eliminates the need for accounting teams to manually download data from various systems in the required formats. Additionally, a billing tool with the capability to automatically recognize revenue in accordance with regulations like ASC 606 and IFRS 15 would be highly beneficial for accounting teams in terms of financial reporting.

  1. Business management teams

For effective business management, a billing tool should extend beyond basic tracking to equip teams with real-time or, at most, daily analytics on diverse metrics. This includes analytics derived from contract and revenue data such as Monthly Recurring Revenue (MRR), Annual Recurring Revenue (ARR), and churn metrics, along with data on user base growth, usage patterns, and trends. These insights will empower teams to identify growth opportunities, make strategic decisions, and manage financial performance with ease.

  1. Product and tech teams

For companies with sizable customer bases, involving product and tech teams in the billing process is common. Billing tools should enable product and tech teams to easily automate interacting with contacts and sending usage data. In provisioning and entitlement cases, the billing system should accurately track and facilitate easy access to relevant data, including analytics on top of it. The billing tool should offer robust API integrations, allowing automated data exchange across diverse business systems and applications. Ideally, billing tools should provide APIs that are essential for customer and contract management, usage data transmission, entitlements, provisioning, and retrieving outputs such as invoices, monitoring data, and analytics. This functionality will not only automate internal workflows but also equip customers with timely reports and insights.

‍2. Integration requirements

Prioritize smooth connectivity, where every aspect of your billing system effortlessly integrates with the rest of your tech infrastructure. Look for capabilities that enable smooth integration with essential components, such as:

  • CRM/CPQ
  • Payments
  • ERP
  • Sales tax
  • Metering/usage data
  • Provisioning 

Integration with the tool of your choice is key, given how you have multiple internal dependencies and existing processes are built around those tools. 

  1. ‍CRM/CPQ

Sales teams utilize Customer Relationship Management (CRM) and Configure, Price, and Quote (CPQ) tools for a range of tasks that include managing their deal pipeline and creating quotes. In some companies, this data is manually entered into the billing tool due to the lack of integration between these tools. This leads to duplicate data entry, systems that are out of sync, and errors due to human intervention. To streamline this process, it's crucial to choose a billing tool that integrates with CRM and CPQ tools, ensuring accurate data retrieval and automating invoice generation, even for complex contracts.

  1. ‍Payments

In the era of expanding digital payment choices, it is essential to provide customers with flexible payment options. Your billing system should smoothly integrate with various payment gateways to offer the variety of payment methods that exist today, ensuring a smooth transaction experience. Additionally, the billing tool should be capable of automating alerts for payment receipts, pending payments, failed payments, and expiring credit cards. Proactivity in communication enhances customer engagement and helps reduce the risk of customer turnover.

  1. ERPs

Accurate financial reporting depends on seamless integration between billing tools and the Enterprise Resource Planning (ERP) system. Choose a billing tool that effortlessly syncs with your ERP, eliminating manual back-and-forth data handling. This saves a lot of manual effort from your accountants as well as back and forth with various teams to get the right data from your billing system into your ERP and eventually close your books on time. All the information needed to create journal entries related to your customers is present in your billing system. A seamless integration ensures this data flows into your ERP without manual intervention. 

  1. ‍Sales tax

The integration of the billing system with specialized sales tax tools becomes a necessity, as it streamlines the complex task of sales tax calculation. A seamless integration reduces the potential for errors and ensures compliance with dynamic tax regulations and the accurate reporting of sales tax across various jurisdictions. 

  1. ‍Metering/usage data

One way to reduce engineering bandwidth is to opt for a billing tool that integrates smoothly with multiple data sources that hold your metering data. This is because different methods of integration are useful in different situations. Quick uploads of CSV files are great for quickly getting started with a billing system. The manual entry of usage data using a web interface is useful for products where the usage is quite low and tracked manually. The billing system's ability to plug into different sources of data (such as your product database or your company’s data warehouse) helps you integrate your original source of data directly with billing without any effort from your engineering team. The billing system having APIs to send usage data is useful for an integration that is easier to maintain in the long run but demands more upfront engineering effort.

  1. Provisioning 

Select a billing tool that seamlessly integrates with the provisioning process. This integration will ensure an accurate reflection of customer purchases from contracts in the billing system into your product systems. As services or products are provisioned or modified, the billing system should be able to send real-time updates, keeping your product’s provisioning system in sync with the contracts that your customers sign. 

3. Different billing models

You don’t want to be playing catch-up with the ever-evolving complexities in billing logic and pricing models. Your billing tool should be able to offer your teams the flexibility to experiment and switch between different pricing models as your product iterates and evolves over time. Select a billing tool that not only comes with capabilities to cater to your current needs and existing pricing models but is also able to automate pricing model experiments in the future. This allows you to explore different business models and usage meters to maximize revenue.

  • Opt for a billing solution that has the capability to accommodate various pricing models. Be it one-time charges, recurring subscriptions, postpaid based on usage, prepaid with postpaid overages, prepaid with provisioning (requiring top-ups for credit depletion), or any combination thereof — choose a tool that effortlessly handles the complexity of your billing models. This is really important so that you never have to think about switching billing systems in the future as your pricing structures evolve.
  • Billing systems that are not future-proof are in many ways rigid, slowing down your sales teams, limiting their ability to get creative with contracts, and eventually affecting your revenue goals. The billing system should empower sales teams with limitless pricing flexibility and contract configuration capabilities, fostering agility in strategy execution. 

4. Comprehensive reporting capabilities

The billing system should equip you with powerful reporting capabilities. This will help you gain actionable insights around churn rate, active subscriptions, usage aggregates, customer balances, revenue numbers, etc., ideally along with customer segmentation insights, empowering informed decisions. Moreover, Deloitte’s report further reveals that customers have also shown interest in receiving insights pertaining to their current and forecast usage as well as spending.

  • The billing system you opt for should provide in-depth financial reports and tax summaries, offering a comprehensive overview of your business's fiscal health.
  • Real-time reports of incoming cash and related revenue numbers will help you stay on top of your cash flow and plan ahead with ease. 

5. Self-serve functionalities

Billing systems with self-serve options are incredibly helpful in gaining better control over billing processes, streamlining operations, and reducing dependency on your internal teams. Evaluate how a billing tool saves you the costs associated with hiring a team to manage the billing and invoicing workflows.

  • Self-serve functionalities that don't demand engineering intervention will help finance teams navigate billing complexities with ease, leading to increased productivity and minimizing operational challenges.
  • These capabilities will also give financial operations teams and other stakeholders more time to enhance product features, meet service delivery benchmarks, and identify new customer service strategies.

‍6. Robust security measures

Minimizing the risk of data breaches should be a top priority for every business. Select a billing tool that is backed by robust security measures that are designed to safeguard your billing operations and customer data.

  • Choose a tool that implements two-factor authentication, adding an extra layer of security to your billing processes. Implementing two-factor authentication for critical billing systems not only secures your organization's data but is also imperative for meeting your security compliance requirements.
  • Ensure the billing system enforces stringent access controls, safeguards confidential customer data, and creates a secure billing environment for your business.

7. Efficient compliance management

Owing to the ever-changing compliance and regulatory environment, the billing system that you select should help you address the evolving dynamics of global regulations and the required standards for your industry.

  • Consider the billing system's capability to handle the diverse landscape of tax regulations in global markets.
  • Ensure the billing system excels in handling regulatory requirements like ASC 606 and IFRS 15 on revenue recognition and meets payment card industry standards.

8. Reliable customer support

If you ever run into a hitch managing your billing processes, quick and reliable customer support from the billing system will help you resolve issues with ease.

For a crucial system like your billing tool, having prompt and reliable support from the billing vendor is essential, particularly given that the quote-to-cash process engages various stakeholders within your organization and issues that arise are typically of higher criticality than usual. Without this support, internal team members tend to take on the role of customer support, aiding other stakeholders in overcoming obstacles they encounter in the process.

  • Right from the point of simplifying implementation and the onboarding processes, billing systems should provide documentation, quick guides, and developer tips to facilitate a quick and efficient adoption.
  • Responsive and dependable customer support via chat, calls, or emails is essential for receiving timely guidance and solutions, preventing disruptions, and ensuring streamlined billing workflows.

9. Global billing standards 

As you step into new markets, billing systems designed for international success will be crucial to embracing global business standards with ease.

  • Firstly, it should provide multi-currency capability. For example, a software company expanding into Europe might price its products in euros for customers in Germany while offering them in pounds for customers in the UK. This not only attracts a global customer base but also supports competitive pricing strategies in international markets and minimizes currency exchange complexities.
  • Along with ensuring accurate time zone logic, the billing system needs to use the correct decimal and thousand separators to ensure the customers are billed correctly — for the right amount, at the right time.
  • Furthermore, ensuring global tax compliance is essential. The billing system should be equipped with integration capabilities, particularly with sales tax providers like Avalara. This integration empowers the system to adapt to various tax regulations across different regions, automatically applying the correct tax rates and handling tax calculations, such as VAT in Europe or GST in Australia, to ensure compliance and prevent legal issues.
