Why Tcgpowertools, an Inventory Management Platform Integrated Global Invoicing API

Sellers don’t just need inventory management—they need a complete business solution. Managing stock is one thing, but handling invoicing, taxes, and compliance? That’s where things get complicated. Without built-in invoicing, sellers are forced to juggle multiple platforms, slowing them down.

    TCGPowerTools was built with one clear goal in mind: to be the ultimate one-stop shop for all card sellers. Managing just 100 cards can already feel overwhelming—tracking sales, monitoring stock, and keeping up with fluctuating card prices is a challenge. And most sellers deal with far more than 100 cards.

    That’s why a tool like this is not only in demand but also faces strong competition. Convenience is everything in this business, and sellers need a streamlined solution that covers all aspects of their operations. It's not just about listing and selling cards—it’s about making the entire process seamless, including paperwork, taxes, and invoicing.

    No one wants to juggle multiple platforms just to keep their business running. Since sellers are already managing their inventory and sales through TCGPowerTools, providing them with a fully integrated backend—handling invoicing and compliance—adds massive value. In the end, this can be the deciding factor between choosing TCGPowerTools or a competitor, while also creating opportunities for upselling additional features.

     

     

    Challenge With Choosing an Invoicing API

    E-invoicing is becoming mandatory in multiple countries and is rapidly being adopted worldwide. With high invoicing costs and time-consuming manual processes, integrating an invoicing feature into a platform would provide significant value to clients. However, building an invoicing system in-house would take years and come with substantial costs.

    Since invoicing wasn’t their core feature, they opted to integrate a third-party API, ensuring it met the following key requirements:

  • Multitenancy – They needed a solution that allowed both them and their clients to connect to the same invoicing system while maintaining data security and separation.
  • White-Labelling – Clients trust TCGPowerTools with their data security and service quality. If invoicing appeared as a third-party add-on, clients might hesitate to use it or even lose trust in the platform.
  • Upselling Support – The API needed to support monetization models, allowing invoicing to be offered as part of a package or as a standalone upsell.
  • Global Invoicing Compliance – TCGPowerTools serves global card sellers, and each country has its own invoicing regulations. The API needed to cover all the countries they operate in, plus additional regions to support future expansion.
  • Credibility – Integrating a third-party API means trusting it to deliver reliable invoicing, satisfy clients, and operate without issues. A provider with years of experience, proven stability, and regulatory compliance was essential.
