Accounting firms and KSeF 2026 – How electronic signatures make accountants' life easier

Challenges for accounting firms in the KSeF era

Accounting firms face a major challenge. The implementation of KSeF means that from 2026 they will have to handle clients' invoices exclusively in the central system. The key problem is managing accesses and powers of attorney. In practice, an accounting firm may have hundreds of clients and every KSeF login must be properly authenticated.

Why the electronic signature is the best solution?

1. Security and control – a qualified signature clearly shows who and when signed the document.
2. Universality – beyond KSeF, the signature is useful for financial statements, sending documents to authorities or signing contracts with clients.
3. Time saving – instead of printing powers of attorney, the firm can sign them digitally in minutes.
4. Convenience for clients – the entrepreneur does not have to perform authorization each time – the firm, having their authorization, does it on their behalf.

Practical example

Imagine an accounting firm serving 80 clients. Without electronic signatures this would mean managing hundreds of tokens and logins. With a qualified signature:

• an accountant logs into KSeF on behalf of a client,
• all actions are legally binding and transparent,
• the invoice handling process shortens by up to 30%.

Electronic seal as an alternative

For firms processing a large number of invoices, an electronic seal is an attractive option that allows process automation. Combined with individual signatures it creates a complete ecosystem for secure document handling in KSeF.

How to prepare your accounting firm for KSeF?

1. Choosing the right solution – individual signature or a company seal.
2. Staff training – so they can use new tools efficiently.
3. System tests – verify KSeF authorization before 2026.
4. Local support – use certification points that offer quick issuance and technical assistance.

Summary and call to action

KSeF is not only a change in invoicing but also in the organization of accounting firms' work. A qualified electronic signature is a tool that helps to navigate this process securely, conveniently and with full control.
