Seven reasons why Flowin is an e-invoicing software developer’s best friend

Flowin assists software companies in their development of e-invoicing solutions by providing a certified API for Peppol connectivity. But we’re not “just another Peppol API”. Flowin’s development history, positioning among partner products and developer-friendly approach truly set it apart from other e-invoicing APIs. Here is a summary of the reasons Flowin is a top choice for software developers working in the e-invoicing space for SMEs.

 

Agnostic API

 

At Flowin, we are 100% dedicated to We do not offer our own e-invoicing software, which means there are no conflicts of interest. Flowin does not tie its software developer customers into any platform or technology stack nor compete for SME customers.  

 

Using the Flowin API for connecting your e-invoicing software into Peppol gives you flexibility, scalability, interoperability and independence. So you can continue to evolve your product and grow your business, with our full support.

 

 

Thanks to partnerships with sister products Zoomit and CodaBox, as well as the Doccle platform, Flowin has unrivalled network access across Belgium for a Peppol e-invoicing API. This means Flowin’s Peppol access point is extensively interoperable and therefore viable for the majority of Belgium-based SMEs to achieve full e-invoicing compliance.

 

Comprehensive open documentation

 

Flowin supports developer autonomy by providing the most developer-friendly open documentation in the e-invoicing API market. Our depth of information via readily available materials, together with easily accessible technical support, provides everything developers need to deploy Flowin quickly and confidently.    

 

Integration with administrative and financial automation

 

Flowin’s development history alongside current and previous sister products, CodaBox and Ponto respectively, places it in a uniquely advantageous position for integration with banking systems for payments & reconciliation purposes. This opens the door for software developers to achieve additional efficiency for their customers.  

 

Responsive support

 

While Flowin is all about providing ease and compliancy through automation, we’re equally aware of the need for personal service. We’re proud to have heard our customers say, time and time again, that we stand out for our personal touch, clear communication and excellent responsiveness.

 

Providing a good user experience and excellent customer journey, with support through each step of implementation and post implementation, is all part of the Flowin service.

Insider knowledge

 

Flowin was conceived from a genuine interest in e-invoicing. Our people have been involved in the official discussion around e-invoicing since 2017 and continue to participate in workshops where legislation is developed. Thanks to the efforts made by Flowin leaders , we are as connected with how the overall e-invoicing landscape is developing as we are dedicated to achieving technical excellence and providing a commercially viable API solution.

 

Unique customer-friendly pricing model

 

Flowin is the only Peppol e-invoicing API provider that charges per user entity rather than per document. This benefits e-invoicing software developers, and their customers, because the cost passed on to each customer for using Flowin is definitive, not linked to the number of documents exchanged.
