How Can Operation Support Systems Become One-Stop Shops With Invoicing

Running an operational support system isn’t just about functionality—it’s about keeping clients on your platform. The best way? Becoming their one-stop shop. But most platforms miss one critical feature that businesses rely on daily: invoicing.

Every business needs invoicing, but few want to deal with the hassle. Building it in-house is costly and complex, while ignoring it pushes clients to competitors. The smart move? Integrate e-invoicing in less than a week and turn it into a loyalty-boosting, revenue-generating feature.

In this use case, we’ll cover:

    Operation Support Systems

    Operation Support Systems (OSS) is usually a specialized software application used by telecommunications service, however it can also be understood as the tools and processes that help a company run its core operations efficiently, one of such being Laboss.

    Goal To Become The One-Stop Shop

    If you run an operational system for a specific business field, you know the key to long-term success is becoming a one-stop shop for your clients. With competition constantly increasing and companies always searching for better platforms, you need to position yourself as the unbeatable choice that keeps clients from switching.

    However, that doesn’t mean stuffing your platform with unnecessary features. No one wants to navigate through hundreds of irrelevant tools just to find what they actually need. The real solution is understanding your clients and providing them with essential business features that truly optimize their workflow.

    One such feature? Invoicing.

     

     

    All Businesses Need Invoicing

    Invoicing is essential for every business, but for SMEs, it’s often a costly and time-consuming hassle—especially with manual or paper-based processes. That’s why e-invoicing is on the rise and mandatory in many countries. Unlike traditional invoices, e-invoices are:

  • Automatically generated - no manual labour.
  • Compliant with country regulations, that are changing monthly now - no fines.
  • Error-free and cost-efficient.
  • Processed instantly for faster payments.

    • However, building this e-invoicing feature in-house would take years, and evolving regulations make it a never ending story. Instead, by integrating it into your platform, you can:

  • Enable instant onboarding – Clients can issue invoices in minutes.
  • Save clients money – They only pay a fraction of what in-house invoicing would cost. (Integrating whole feature themselves is not worth it, too expansive)
  • Offer flexibility – Bundle invoicing into your platform or upsell it as an extra service.
  • Unlock a new revenue stream – Earn through subscriptions or usage-based pricing.
  • Boost customer loyalty – A complete solution keeps clients engaged and ahead of competitors.
  • Become One-Stop Shop - With invoicing you provide huge value people have problem with but ignore many times. However, when solved, they really appreciate it.

    Invoicing Challenge

    Integrating an invoicing feature can be challenging if not done correctly. Building an invoicing feature is hard with global regulations constantly evolving, not to mention the year-long development process and the cost of multiple developer salaries. The smarter approach? Integrate a third-party API. However, not all APIs are created equal. An API you need should support:

  • Multitenancy – Allows both you and your clients to use the same API while keeping data secure and private. This ensures smooth integration into your platform while enabling others to use it as well.
  • Built-In-House Look – Clients trust your platform. If invoicing feels like a third-party add-on, they may hesitate to use it. White-labeling ensures that invoicing blends seamlessly into your platform with your branding.
  • Global Compliance – The API must support all the countries your business operates in—including those of your clients. Having extra country support is even better for future expansion.
  • Strong Integration Support – A reliable API provider should offer detailed documentation and responsive support to help with integration and troubleshooting.
  • Proven Market Credibility – Compliance takes years to perfect. Choosing an untested API risks flaws and struggles to keep up with ever-changing regulations. A well-established API ensures reliability and long-term compliance.
