How Can Business Productivity App Become One-Stop Shops With Invoicing

Business owners don’t want to juggle multiple tools. The more your app simplifies their workflow, the more valuable it becomes. That’s why top platforms are becoming one-stop shops—and invoicing is the next must-have feature.

Invoicing is a hassle for most businesses, but a necessity. Instead of letting users switch to another tool, why not offer it yourself? With a seamless invoicing integration, you keep users engaged, unlock a new revenue stream, and stand out in the market—all without the cost of building it from scratch.

    Goal To Become The One-Stop Shop

    Every business development app aims to become a one-stop shop for its users. By offering a comprehensive solution, you retain existing clients and attract new ones—eliminating the need for them to switch between multiple apps and software.

    However, this doesn’t mean adding unnecessary features that only a small percentage of users might find useful. Instead, the focus should be on solving as many core business challenges as possible, while keeping the software intuitive, easy to navigate, and packed with only essential tools.

    That’s why many apps are now integrating 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.
  • Automatically compliant with country regulations, that are changing monthly now.
  • 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.
  • 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. As we saw, 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-labelling 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.
