NATIONAL e-INVOICE SYSTEM (KSeF)
KSeF is a government platform for issuing, sending, receiving, and storing invoices. All e-invoices are transmitted directly to the Ministry of Finance’s central database, where they are validated, assigned a unique identification number, and made available to the recipient.

KSeF in FASTPROFIT.5 ERP includes:
- creating invoices and managing KSeF processes in one place,
- issuing, receiving, and viewing invoices and correction invoices compliant with the FA(3) structure,
- searching and downloading issued documents in XML or PDF formats,
- sending invoice visualizations to business partners,
- access to invoices issued in offline mode and subsequently transmitted to KSeF,
- QR code support, including access to invoices via QR code,
- data verification and detection of potential errors,
- ability to edit data before submitting documents to KSeF.
EDI
EDI (Electronic Data Interchange) is the electronic exchange of business documents between companies or institutions in the form of files with a standardized structure.
- It enables cooperation between organizations using different IT systems, provided those systems support EDI messages.
- Most commonly, EDI is used for exchanging documents between suppliers and customers.
Benefits of EDI in FASTPROFIT.5 ERP:
- automation — no need for manual document processing,
- standardization — data can be read by different systems,
- reduced errors,
- high processing speed,
- cost savings,
- Improved resource management.
API
FASTPROFIT.5 ERP leverages both EDI and API (Application Programming Interface) technologies.
An API allows one application to use functions or data provided by another application, system, or service — without needing to understand its internal structure.
- API integrates various types of applications (not just documents),
- enables direct, real-time communication,
- and is highly flexible and easy to integrate with other systems.
Because both EDI and API have their own strengths and limitations, the optimal solution is always tailored to the client’s specific needs.
The main advantage of using API in FASTPROFIT.5 ERP is the ability to expand the system with new functionalities without building them from scratch, resulting in significant time and cost savings.
INTEGRATION WITH THE BASE.COM PLATFORM
Base.com (formerly BaseLinker) is a comprehensive e-commerce management system that automates processes and centralizes order handling from multiple sales channels (e.g., marketplaces).
PRODUCT EXPORT
FASTPROFIT.5 ERP enables exporting available products directly to Base.com, making sales management significantly easier.
ORDER IMPORT
Conversely, FASTPROFIT.5 ERP can import customer orders and use this data to generate the documents required to complete the sales process.
