Smart e-invoicing Poland (SmartKSEF)- comprehensive communication platform for processing and reconciling e-invoices.

From February 1 or April 1, 2026 the use of SmartKSeF, the Ministry of Finance’s new system of processing e-invoices, will become mandatory for every business operating in Poland. There are only a few months left to prepare for this change. At Exorigo-Upos, we have developed a solution that will allow you to easily integrate a range of customer checkout systems with the government’s system. Our software enables seamless communication with SmartKSeF and the efficient processing of e-Invoices.

SmartKseF – easy integration with a range of systems

Years of experience in​​creating and integrating IT solutions for retail, means that we know the needs and challenges of customers in this area. That is why we have created one solution for many invoice issuing systems. This means that it will not be necessary to adjust each of them to the requirements and subsequent updating of the new fiscal legislation FSC.

A clear, dedicated API is also of great importance, as it will enable the easy and agile integration of SmartKSeF with your IT stack.

The standard interface and ready to go solution meet another need – fast, trouble-free implementation. This is very important as the SmartKSeF will be a mandatory system from July 1, 2024 with regular updates, so there is little time left to implement and test solutions for communicating with it.

Why is it worth reaching for e-Invoices in SmartKSeF?

First, SmartKSeF ensures invoicing security and is responsible for validation and monitoring of availability.

In one place, it provides the option of tracking the status of all e-invoices and an archive of processing history. It is easy and convenient to use in everyday work.

In addition, SmartKSeF significantly facilitates e-Invoice processing by detecting errors at an early stage. This is made possible thanks to following the rules and requirements of the Polish Financial Supervision Authority, which every business is required to follow.

Our solution will be constantly developed by a dedicated team of experts. We already have a roadmap of a range of new functionalities, which we will be implementing gradually as the Ministry of Finance system for e-invoicing is used more widely

The most important principles of SmartKSeF:


Supports all types of e-Invoices


Provides access to documents submitted by various sales systems, in one place.


Validates downloaded data.


Sends feedback in case of error.


Provides the processing status – received from the FSC.


Queues sales invoices in the event of unavailability of the FSC or lack of internet.


Automatically retries invoicing in the FSC.

Why is it worth implementing SmartKSeF to handle e-Invoices?

Exorigo-Upos has gained retail experience for over 20 years in providing solutions, IT services and their integration. We have many proprietary systems that are responsible for key business processes in most retail chains in Poland.

One of them is EFT payment cloud. This system supports the seamless transmission of huge amounts of data (up to 3.5 million transactions per day) and is responsible for the security of payment card operations at checkout. It is easy to integrate with other mission critical solutions – especially cash register systems that enable the sale of goods in retail chains.

The implementation of our SmartKSeF connector supports a fully automated, comprehensive e-invoice service, which removes an important headache from your daily operations.

In addition, we offer a flexible approach to deployment. We can provide the software for you to implement yourself, or we offer a full managed e-invoice reconciliation service, which offers significant savings whilst guaranteeing operational efficiency which is compliant with the latest fiscal legislation.

The ambitious plan to implement a new shop coincided with the COVID-19 pandemic, which meant that in addition to creating a totally new and unique solution, Exorigo-Upos had to support the existing e-commerce platform, which had to meet significantly increased demand and adapt to the rapidly changing market. An essential element of implementing such a large service is mutual trust and the dedication and high skill level of the contractor.
