Implementing the National e-Invoice System (KSeF) is one of the major technological challenges facing Polish companies today. The complexity of the official API, limited access to documentation, and lack of efficient technical support force many organizations to rely on the services of investors. One of the leaders in this field is ksefapi.pl, a solution that, in addition to a refined API and ready-made libraries, offers something much more valuable: true technical support with a human touch.
Direct contact with people – a story that really happens
Imagine this: integration with KSeF is already underway. Your IT team is testing invoice sending but encounters an error with unclear content, perhaps something related to digital signatures or authorization. Government documentation provides no explanation, and Stack Overflow is silent. You call or email official support, but you don't get a response for days. Meanwhile, with ksefapi.pl, a single email is enough. Within a few hours, you receive a response, not from a bot, but from a specific person. Sometimes with support questions, sometimes with a ready-made solution. Each message includes the phone number of the person responsible for your request. You can call, chat, ask questions, and even walk through the code together on screen. This is technical support with a human face. Not a marketing slogan, but the daily practice of a team that truly knows their stuff and treats customers as partners.
Assistance also in the implementation phase – not only "after the fact"
At ksefapi.pl, we understand that most problems arise not when everything is up and running, but precisely during the implementation phase. This is when the IT team must compile documentation, understand authorization processes, master the structured invoice scheme, and align the API with internal systems. That's why our technical support team is involved from the very first stages of integration. We not only help interpret messages and error codes, but also advise on how to effectively design business processes around KSeF. Clients receive not only answers but also best practices, implementation frameworks, and advice on integrating KSeF with accounting systems, ERP systems, or proprietary solutions. This ensures the entire process runs more smoothly, significantly reducing the risk of errors and delays.
Help that doesn't just answer – but looks for the source of the problem
In the IT world, a large portion of technical support operates on the principle of "here's a link to the documentation, good luck." At ksefapi.pl, we approach it differently. For us, a ticket isn't a problem to be "checked off," but an opportunity to understand what's going on and help the customer as best we can. When we receive an email with an error log, we analyze it, check the code the customer ran, and compare it with our examples. Often, we prepare a code snippet to fix the problem, or update a library or documentation if we discover a missing scenario. In practice, this means less frustration, less time spent debugging, and more time actually working with invoices and the ERP system.
Updates in line with the evolution of KSeF – peace of mind and security included
KSeF is changing, and faster than you might think. New versions of XSD schemas, revised error messages, and a different approach to authorization tokens all mean that standalone integrations must be constantly monitored and updated. With ksefapi.pl, customers don't have to worry about this. Changes are monitored continuously, and our libraries and REST API are adapted in advance. Customers receive a ready-made solution that simply works, without having to search GitHub repositories or browse forums.
You can call. Really.
In the world of SaaS, the ability to directly contact a technical person by phone is becoming increasingly rare. We do it differently. If you have a problem or need to talk, you can always call the person handling your request. We don't redirect you through automated systems, keep you waiting in line, or ask you to verify your identity through three departments. You'll find the phone number in the footer of every email, and the conversation is conducted without unnecessary formalities, technically, substantively, and efficiently.
Feedback that changes the product – your opinion matters
Technical support at ksefapi.pl is not only about reacting, but also—perhaps even more importantly—listening. Every report, question, or suggestion can contribute to the development of the entire platform. It's thanks to listening to our customers that we've added new types of client libraries for JAVA and .NETWe've improved authorization handling and updated the documentation with missing use cases. Customers have a real influence on the service's development direction because we know that the best products are created through dialogue, not in isolation from user needs.
In summary, choosing a solution for integration with KSeF isn't just a technological decision. It's also about whether you'll have someone to talk to if something goes wrong. At ksefapi.pl, we understand that every line of code is a potential error point, and every error means potential delays or even business losses. That's why we provide you with more than just documentation and APIs; you also receive real, fast, and knowledgeable technical support.
