Should you Build or Buy the Billing System?
Building home-grown billing systems is a good idea until a two-month sprint becomes a full-blown one involving at least 10 engineers and extending way beyond 12 months.
Most organizations start with “just-good-enough” billing systems that works well enough—up to the point your business starts to scale up.
As you acquire more customers and start integrating with more tools and databases, not to mention experimenting with flexible pricing strategies, your billing workflows only get more and more complex.
This is why we find many businesses at a crossroads where they have to decide between continuing to build an in-house billing system or switching to a vendor with an off-the-shelf solution.
We’re putting an end to this dilemma…
In this webinar, we briefly cover
- The need to think long-term about billing
- Stakeholders in billing systems
- When building in-house makes sense
- Why moving to a good billing vendor could solve your billing worries

Webinar Summary
Q. What are the key considerations when building an in-house billing system?
The key consideration when building an in-house billing system is understanding your company's requirements. Every business has different products, pricing models, and growth strategies. Therefore, it's crucial to know what dimensions and features your billing system will need to handle. These factors directly impact the decision to build or buy.
Q. How do you decide whether to build or buy a billing system?
The decision to build or buy depends on your company’s size, complexity, and future growth. Startups or smaller companies may want to buy an off-the-shelf solution to save time and resources. In contrast, larger companies with complex billing requirements or unique needs might prefer to build their system in-house for better control and flexibility.
Q. What are the advantages of using a vendor for billing systems instead of building in-house?
Using a vendor allows for faster time-to-market, especially for startups or small companies. Vendors offer pre-built solutions for common billing features like payment integration, invoicing, and customer reminders. They’re well-established and can handle these tasks efficiently, freeing up your team to focus on product development and business growth.
Q. What are the key challenges in building an in-house billing system?
Key challenges include flexibility, scalability, and operational efficiency. As the business grows, your billing system must adapt to new pricing models, customer needs, and regions. Ensuring that the system can scale without sacrificing performance or flexibility is crucial.
Q. When is it better to build an in-house billing system?
Building in-house makes sense when your product is complex, has multiple pricing dimensions, and serves a variety of customers. Larger companies with unique needs may benefit from a custom solution that allows them to maintain full control over the system and make rapid changes as required.
Q. What are the pros and cons of building an in-house billing system?
The pros include greater control, customization, and flexibility to meet specific business needs. The cons are significant time and resource investments. Building an in-house solution requires a strong engineering team, ongoing maintenance, and potential delays in scaling the system to meet growing business needs.
Q. How does billing relate to other business functions, and who are the key stakeholders in a billing system?
The key stakeholders are:
- External customers: They need clear and transparent billing data.
- Product & Engineering teams: They collaborate on defining features and monetizing them.
- Sales & Customer Success teams: They use billing data for upselling, renewals, and customer insights.
- Finance & Accounting teams: They rely on accurate billing data for revenue recognition and financial reporting.
- Internal auditors: They ensure compliance and accuracy in billing data.
Q. How should billing systems handle customer billing transparency?
Billing transparency is essential for customer satisfaction and chargebacks. Customers should have easy access to detailed billing data to understand their costs, usage, and potential optimizations. This helps reduce disputes and gives customers more control over their spending.
Q. How should a billing system support internal teams like Finance and Sales?
The billing system must provide Finance with real-time, accurate data for revenue recognition and forecasting. Sales teams use billing data for upselling and monitoring customer usage. The system should allow both departments to access flexible, detailed data for better decision-making.
Q. How does billing data impact forecasting and revenue recognition?
Billing data is crucial for accurate revenue recognition and forecasting. Finance teams rely on timely billing data to complete their forecasts. If the data is incorrect or delayed, it can lead to errors in financial reporting, especially for public companies that must meet strict regulatory requirements.
Q. What role do product and engineering teams play in defining a pricing model for billing?
Product and engineering teams define product features, but they work closely with the billing team to ensure that the pricing model is feasible and supports the product's monetization strategy. This collaboration ensures that new products are priced correctly and that the billing system can handle the pricing model.
Q. What are the main challenges in handling pricing models for a billing system?
The main challenges include handling complex pricing structures, regional pricing, multiple customer segments, and pricing flexibility. Billing systems must be able to support these changes and adapt to new customer demands, which can add complexity to the implementation process.
Q. What factors should be considered when integrating a billing system with accounting software?
When integrating a billing system with accounting software, it’s important to ensure smooth revenue recognition and reporting. The data flow between systems should be seamless, and both systems should be able to handle adjustments in real time. Having a clear separation of responsibilities between the billing system (for invoicing) and accounting software (for revenue recognition) is critical.
Q. What is the importance of security and compliance in a billing system?
Security and compliance are crucial for protecting sensitive financial and customer data. Billing systems must adhere to regulations such as GDPR, SOC 2, and industry-specific standards. Ensuring secure data access and compliance with these standards is necessary to maintain customer trust and avoid legal issues.
Q. How can you test and validate a billing system?
Testing and validation are key to ensuring the accuracy of billing data. Automated tests, including blackbox testing, should be in place to detect errors in the system. Variance testing ensures that new versions of the system remain backward-compatible, and testing should be continuous to catch any potential issues.
Q. What challenges arise when billing systems become too complex or inflexible?
When billing systems become complex or inflexible, it can lead to inefficiencies and difficulties when adapting to new business needs. If the system isn’t scalable, it may become a bottleneck as the company grows. Flexibility is key to ensuring that the system can evolve alongside the business without causing delays or problems.
Q. How can AI and automation improve billing systems?
AI and automation can significantly improve billing systems by streamlining processes and reducing manual work. For example, AI can be used to optimize billing data, provide better customer insights, and automate invoice generation, which reduces human error and improves operational efficiency.
Q. How do you handle refunds and customer disputes in a billing system?
A good billing system should allow for easy processing of refunds and customer disputes. Instead of involving engineering teams, sales or customer success teams should be able to process refunds or adjustments through a self-service portal, making the process quicker and more efficient.
Q. How do you ensure scalability in a billing system as the company grows?
Scalability is achieved by ensuring that the billing system is flexible and can handle increasing volumes of transactions, customers, and data. An API-first architecture allows for easy integration with other tools and systems, ensuring that the billing system can grow alongside the company.
Q. What are some examples of when to build and when to buy a billing system?
For smaller companies with simple pricing models, buying an off-the-shelf solution makes sense. However, for larger companies with complex products, high transaction volumes, and global customers, building in-house might be necessary to maintain control and flexibility over pricing, billing models, and data integration.
