KSeF and Your Accountant — How to Grant Permissions and Organise Access
Implementing KSeF is not purely a technology question. It is also a question of who issues invoices, who receives them, and who has access to data in the system.
If you work with an in-house accountant or an external accounting office, access management is one of the most important elements of the entire implementation.
Do You Have to Grant Access to Each Accountant Separately?
Not always — and that is good news for business owners who would rather not spend a week clicking through individual permissions for each person.
You can grant access rights to the entity as a whole — meaning the accounting office. During mandatory KSeF the option also exists to allow that entity to delegate permissions to its own employees.
In practice this means less manual work on the business owner's side.
Why Does This Matter So Much?
Because KSeF changes how invoices are accessed. In many businesses the old flow looked like this:
- the owner sends a PDF by email,
- the accountant downloads documents from a shared folder,
- some data is re-typed or imported manually.
KSeF creates a different document flow, so you need to define:
- who issues documents,
- who receives them,
- who handles corrections,
- who has authority to act on behalf of the business.
How to Plan KSeF Access in a Small Business
The best starting point is a simple division of roles.
Model 1: The owner issues all invoices
The simplest setup for a solo freelancer or sole trader without a team.
Model 2: Owner issues invoices, accountant handles bookkeeping
In this case the accountant needs appropriate read and document-handling permissions.
Model 3: The accounting office issues invoices on behalf of the business
This requires well-configured access and clear lines of responsibility.
The Most Common Mistakes When Granting Permissions
1. Defining the process too late
The business implements KSeF technically but does not establish who does what.
2. No procedure when changing accountants or accounting offices
Permissions should be reviewed and updated just like passwords or bank access rights.
3. Granting excessively broad access without reason
Not everyone needs full access to everything.
4. Not testing before going live
It is worth checking in advance whether permissions work as intended.
What to Agree With Your Accounting Office
Before fully switching to KSeF, it is worth discussing:
- who technically issues invoices,
- who handles corrections,
- how incoming documents are received,
- who is responsible for emergency situations,
- whether the accounting office uses internal permission delegation within its own team.
Key Takeaway
Well-configured permissions in KSeF save time, reduce stress, and prevent unnecessary calls along the lines of: "could you send me that invoice again, the system won't let me in".
If you work with an accounting office, treat access management as part of the core architecture of your business — not as an administrative detail, but as a key part of daily operations.
