Manage permissions
In SaldeoSMART you can easily assign and manage your coworkers’ access rights. All it takes is generating a single KSeF token for your company and adding it to SaldeoSMART. Thanks to our integration, you avoid multiple logins to the government system. Assign the right permissions directly in SaldeoSMART and work comfortably from one application.
Issue invoices easily and with confidence
Invoices created in SaldeoSMART comply with the requirements of the Ministry of Finance. Our system includes a mechanism that verifies whether each document follows the correct logical structure defined by the Ministry. In addition, the application automatically checks the invoice for accuracy before sending it to KSeF.
Automate your work
Many companies worry that the introduction of the National e-Invoice System (KSeF) will make working with documents more time-consuming and slow down established processes. At SaldeoSMART, we know that repetitive tasks can be automated to save time. That’s why we’ve built in automation options such as bulk invoice submission to KSeF and automatic invoice retrieval from KSeF. With SaldeoSMART, daily document handling becomes simple and efficient.

FAQ
What are the KSeF implementation deadlines❓ The rollout of KSeF is divided into stages, giving companies time to prepare for the changes: From February 1, 2026 – mandatory for the largest enterprises with annual turnover above PLN 200 million (for 2024), From April 1, 2026 – mandatory for most other businesses, From January 1, 2027 – mandatory for the smallest taxpayers issuing only low-value invoices. This phased approach ensures every company has time to adapt, test the new system, and get ready before it becomes obligatory.
What exactly is KSeF and how does it work❓ KSeF is a government system through which all invoices in Poland will be processed. It ensures that issued documents follow a single, standardized format and are immediately delivered to the tax administration. In practice, this means fewer formalities, greater security, and smoother invoice circulation between companies and accounting offices.
Who will be required to use KSeF❓ All VAT taxpayers operating in Poland will be obliged to use KSeF. This means e-invoicing will become mandatory for business-to-business (B2B) sales, transactions with public institutions (B2G), and settlements with foreign contractors. It will not apply to invoices issued to individual consumers (B2C). In practice, every company — regardless of industry or size — will need to prepare for issuing invoices through KSeF.
What are the consequences of not using KSeF❓ Failing to issue an invoice in KSeF, or doing it incorrectly, can result in severe financial penalties. In the worst case, the tax office may impose a sanction equal to the full VAT amount on the invoice, or — if the invoice does not include VAT — up to around 20% of its value. That’s why it’s crucial to implement the system correctly and ensure compliance with the regulations.
What are the benefits of using KSeF❓ KSeF is not just a legal requirement — it also offers many advantages for businesses: Faster VAT refund — even in 40 days instead of 60, A single, consistent invoice format, making documents clearer and error-free, No more papers or email attachments — invoices are delivered fully digitally, Easier and quicker document flow between contractors, No risk of invoices being lost or damaged — the system archives everything for 10 years, Full transparency: always know when and to whom a document was delivered, Simplified corrections — all adjustments follow a unified process, Saving space and time — no need to store paper binders anymore.
