KSeF for farmers - basic information
The National e-Invoicing System (KSeF) changes how invoices are issued, received, and organized in Polish agriculture and across the food supply chain.
Short summary
The National e-Invoicing System (KSeF) is changing how invoices are issued, received, and organized in Polish agriculture and across the entire food supply chain. For VAT-registered farmers, agronomic advisors, processors, fruit and vegetable distributors, and companies cooperating with farms, this represents not only a new obligation but also an opportunity to streamline documentation, accelerate data flow, and reduce manual re-entry of costs.
In practice, the greatest benefits will be achieved by those participants who integrate KSeF with daily farm management or supplier relationships. Access to an invoice alone does not solve the problem if the document still needs to be manually assigned to a field, crop, product batch, treatment, or production cost.
KSeF for farmers – basic information
KSeF, the National e-Invoicing System, is a government platform used for issuing, receiving, transmitting, and storing structured invoices. A structured invoice is not a simple PDF file or scanned document but a document saved according to a defined data structure that allows accounting, commercial, and operational systems to read and process it automatically.
This is particularly important in agriculture because invoices are not only accounting documents. They also carry information about purchases of fertilizers, crop protection products, fuel, spare parts, transport services, nursery material, or sales of agricultural products. When invoice data can be automatically linked with fields, treatments, warehouses, and economic results, the management value of documentation increases significantly.
This is especially important in the Polish market, where some farms already operate with digital systems while others still rely on paper documents, spreadsheets, and messaging tools. According to a 2025 study by the European Commission and the Joint Research Centre, 93% of surveyed farms in the European Union declared using at least one IT tool or software solution, and 79% used at least one technology typical for crop production. This shows that agricultural digitalization is already widespread, although its level of integration still varies considerably.
Key facts and timelines
Many simplifications and misunderstandings have emerged around KSeF. It is therefore worth clarifying several basic rules first. These determine whether a farm, purchasing company, or processor must already operate in the new model or is still preparing for full implementation.
| Area | Status as of 06.03.2026 | Practical meaning |
|---|---|---|
| Mandatory invoicing in KSeF for the largest companies | from 1 February 2026 | Applies to entities whose sales in 2024 exceeded PLN 200 million gross |
| Mandatory invoicing in KSeF for other taxpayers | from 1 April 2026 | The key date for most companies cooperating with agriculture |
| Temporary simplification up to PLN 10,000 gross monthly | until 31 December 2026 | In certain cases invoices may still be issued outside KSeF |
| Receiving invoices via KSeF | mandatory from 1 February 2026 | Important for processors, distributors, and companies purchasing from farmers |
| VAT RR invoices in KSeF | optional from 1 April 2026 | Requires a declaration from the flat-rate farmer and designation of the buyer |
| Invoice archiving in KSeF | 10 years | Reduces the risk of lost documents and simplifies auditing |
Benefits and challenges for different stakeholder groups
This article addresses several groups participating in the same supply chain but viewing KSeF from different perspectives. For some it is primarily an accounting obligation, for others a source of cost data, and for others still a tool that organizes purchases, sales, and supplier settlements.
| Stakeholder group | Most common problem | Potential benefit |
|---|---|---|
| VAT-registered farmers | Scattered cost documentation and manual data entry | Faster invoice circulation and better cost control |
| Flat-rate farmers | Low transparency of VAT RR documentation | Better control over documentation and sales |
| Agronomic advisors | Lack of current cost data | Better recommendations and improved fertilizer calculations |
| Fruit and vegetable processors | Large number of suppliers and inconsistent documents | Faster accounting and fewer errors |
| Fruit and vegetable distributors | Time pressure and many product batches | Better timeliness and improved documentation order |
| Agricultural equipment manufacturers and service companies | Difficulty coordinating documents across branches | Standardized documentation and easier integration |
KSeF and flat-rate farmers
Flat-rate farmers are most often connected to VAT RR workflows. In KSeF, VAT RR handling is optional and requires a declaration and buyer authorization.
How to prepare a farm or company for KSeF
- Verify tax status and document types.
- Define roles for issuing, receiving, and approving invoices.
- Choose the workflow model and tools.
- Standardize supplier and resource naming.
- Start with a pilot process before full rollout.
Comparison of KSeF handling approaches
| Area | Basic KSeF tools | Integrated model (FarmPortal) |
|---|---|---|
| Issue/receive invoices | Yes | Yes |
| Assign invoice to field/crop cost | Limited | Yes |
How FarmPortal supports KSeF implementation
FarmPortal – a farm management system – can act as an operational layer above the invoice itself. This means the document does not function only as an accounting entry but becomes part of cost management, production management, and field documentation processes.
Main functions and benefits
- Cost and documentation register – invoices can be linked to fields, crops, seasons, and farm history.
- Support for fertilization planning – fertilizer purchases feed fertilization calculations.
- Fertilizer calculator – cost and agronomic data support fertilization decisions.
- Crop protection products database – easier organization of purchases and treatments.
- Crop protection products browser – quick verification of products and their applications.
- Operational history and reports – less manual work when preparing reports.

Implementation checklist
- List documents that must be issued in KSeF.
- Define user permissions and process owners.
- Unify supplier and product naming conventions.
- Test workflow on a small sample first.
Case study
Typical implementations show that the biggest gains come from connecting invoices with operational data and cost analysis, not from archiving alone.
User opinions
"After organizing invoice workflows, monthly cost reporting became faster and errors dropped significantly."

Summary
KSeF should be treated as part of a broader operational process. The best results come from integrating invoice data with field operations and cost management workflows.
