FOP Documents: What to Keep on Paper vs Electronically

Which documents a Sole Proprietor (FOP) in Ukraine must have on paper, and which can be stored only electronically

For a Sole Proprietor (FOP) in Ukraine, the general rule is as follows: an electronic document does not lose its legal force simply because it is not on paper. Properly created electronic contracts, acts, invoices, primary documents, tax documents, receipts, EDI documents, and documents signed with a QES can fully replace paper. The critical issue is not whether the document is printed, but whether it exists as a proper original, whether its content, date, signature, and author can be confirmed, and whether the entrepreneur can quickly provide it during an inspection. (Law of Ukraine)

A FOP cannot always work completely without paper. Most often, this is realistic for an entrepreneur without employees, without a stationary point of sale, without special licenses, outside the food industry, and without cases where paper forms are used according to RRO rules. However, if there is a store, cafe, warehouse, delivery service, hired employees, food products, excisable goods, or specially regulated products, then alongside the electronic archive, there are specific mandatory physical documents, physically accessible information at the facility, or documents that must be presented at the place of activity. (Law of Ukraine)

1. Basic rule: electronic documents for FOPs are fully valid

The Law on Electronic Documents explicitly states that the legal force of an electronic document cannot be denied solely due to its electronic form, and the admissibility of such a document as evidence cannot be denied just because it is electronic. For documents signed with a QES, an additional rule applies that a qualified electronic signature has the same legal force as a handwritten signature. (Law of Ukraine)

For primary documents, this is also confirmed by the law on accounting: primary documents drawn up in electronic form are used in accounting provided that the requirements of the legislation on electronic documents are met. This means that a FOP can generate and store a significant part of contractual, accounting, and settlement documents in electronic form, if the requirements for details, signing, and storage are met. (Law of Ukraine)

At the same time, the Tax Code obliges the storage of documents related to the calculation and payment of taxes and fees. The minimum retention periods depend on the type of document: in the current version of paragraph 44.3 of the TCU, periods of 1095, 1825, or 2555 days apply depending on the document category. Therefore, for a FOP, the key is not the presence of a folder with papers, but the presence of a complete and accessible document archive. (Law of Ukraine)

2. What a FOP can usually store only electronically

In most standard business processes, a FOP may not duplicate on paper:

For an online store, it is particularly important that the seller must provide the buyer with information about themselves, promptly confirm receipt of the order, and provide a document confirming the receipt of funds. The law does not require that this must necessarily be a paper medium: it can be an electronic document, receipt, check, or other appropriate supporting document. (Law of Ukraine)

3. When paper or a physically accessible document is still needed

A paper archive is not a universal obligation for all FOPs, but there are cases when a paper or physically present document is still required.

3.1. Employees

For a FOP-employer, labor relations cannot exist "without documents". The Labor Code requires proper formalization of labor relations and prohibits admitting an employee to work without concluding an employment contract and without notifying the tax authority. At the same time, during martial law, by agreement of the parties, an employment contract can be concluded in the form of an electronic document. Thus, a written form is mandatory, but it does not always have to be strictly on paper. (Law of Ukraine)

3.2. RRO, PRRO, KORO, settlement books

Law No. 265 regulates both classic RROs and software RROs (PRRO). For PRRO, the main array of documents is electronic. But the law also provides for cases when settlement operations can be conducted using settlement books and books of accounting for settlement operations (KORO). Therefore, paper KORO/RK are not needed by all FOPs, but only when the entrepreneur actually works in a mode for which these forms are prescribed by law. By itself, the transition to a PRRO does not create a general obligation to have a paper book or a paper archive of receipts. (Law of Ukraine)

3.3. Physical point of sale, cafe, pickup point

For stationary trade and service, the rules of trade activity and consumer service apply. This means that for a store, cafe, salon, pickup point, or other physical object, what matters is not only the availability of an electronic archive, but also physically accessible information at the place of activity and the ability to promptly show documents related to the operation of that specific point. (Law of Ukraine)

3.4. Medical books

In areas where the law requires medical examinations and maintaining personal medical books, such a book remains a paper document of a prescribed form. For public catering, food production, and certain household and service sectors, completely abandoning paper in this regard does not work. (Law of Ukraine)

3.5. Food products

If a FOP sells, stores, transports, or manufactures food products, special requirements must be checked: state registration of facilities, and in some cases, an operating permit, traceability, and documents regarding batches and suppliers. A significant part of such documents can be stored electronically, but certain documents must be actually accessible at the facility, and paper medical books may be mandatory for personnel. (Law of Ukraine)

3.6. Excisable goods

For alcohol, tobacco products, liquids for electronic cigarettes, and fuel, a special licensing and control regime applies. A paper form is no longer the sole confirmation of the right to activity, but the very right to sell or store depends on a valid license and information in registers, and violations entail special sanctions and may lead to cancellation. (Law of Ukraine)

3.7. Commodity documents and product safety

For a commodity business, the absence of paper per se is not an automatic violation, but the entrepreneur must have documents confirming the origin of the goods, their characteristics, and for regulated non-food products — documents provided during market surveillance. This is especially important for products requiring conformity checks, labeling, instructions, and safety verification. (Law of Ukraine)

4. What this looks like for different business models

FOP without employees and without a physical point. If an entrepreneur works only online, has no hired personnel, does not sell excisable goods, does not work with food products, and does not use paper forms according to RRO rules, they can often work entirely in an electronic format. However, they must still properly store contracts, payment confirmations, tax documents, commodity documents, and consumer documents. (Law of Ukraine)

Store. For a store, in addition to an electronic archive, the physical organization of the point of sale, commodity documents, settlement operation documents, and the ability to quickly provide documents during an inspection are important. If the activity falls under RRO/PRRO, the rules of Law No. 265 apply; if the product is subject to market surveillance, technical and shipping documentation is required. (Law of Ukraine)

Cafe or other public catering establishment. Food legislation requirements are added: registration of facilities, traceability, documents for raw materials and batches, and for personnel — medical books where prescribed by law. Working entirely "paperless" is the most difficult here. (Law of Ukraine)

Warehouse and delivery. If the warehouse is part of a food chain or is used to store specially regulated goods, document requirements become stricter. If it is a standard non-food warehouse, the key elements are confirming the origin of goods, turnover, safety documents, and the ability to trace the supply chain. For e-commerce delivery, order confirmations, payment, dispatch, returns, and communication with the consumer are also critical. (Law of Ukraine)

FOP with employees. Such a FOP cannot have a "we format nothing" model. Documents on hiring, notification to the State Tax Service, HR, and payroll documents must exist. Some of them can be electronic, but they must be properly executed, accessible, and suitable for confirming labor relations. (Law of Ukraine)

5. What to do if a FOP currently has nothing on paper at all

First, divide all documents into four groups: tax and primary; commodity documents; HR; special industry documents. After this, check whether there is an electronic original for each document, whether there is a signed file or other proper original carrier, whether receipts and bank confirmations are saved, and whether missing documents can be recovered from the bank, EDI, electronic cabinet, state registers, or counterparties. (Law of Ukraine)

Next, organize the electronic archive so that you can quickly find a document by date, counterparty, amount, product batch, employee, or activity object. Original signed files, signature certificates, reporting acceptance receipts, and backups should be stored separately. Merely a printed PDF without confirmation of signing does not always solve the problem of proof. (Law of Ukraine)

After this, finalize only those positions where paper or physical presence is truly needed: medical books, paper KORO/RK — if they apply in your model, documents or information that must be at the facility, as well as special paper forms if directly required by specialized regulations. The law does not oblige you to simply print everything "just in case". (Law of Ukraine)

6. What are the risks if documents are missing or improper

For taxes, the risk arises not from the lack of paper as a medium, but from the failure to ensure the storage of documents necessary for tax control. This is what is penalized under the Tax Code. (Law of Ukraine)

For settlement operations, sanctions of Law No. 265 apply. If a FOP is obliged to use RRO/PRRO or other prescribed forms but violates these rules, liability occurs under specific articles of this law. (Law of Ukraine)

For employees, the risk is highest when there is actual admission to work without proper formalization. HR documents can be electronic where allowed, but their complete absence creates grounds for labor sanctions. (Law of Ukraine)

For licensed, food, and excisable activities, the consequence can be not only fines but also the cancellation, suspension, or loss of the right to operate under a special procedure. This is why a FOP in these areas must separately check not only the form of document storage but also the completeness of the permitting and commodity block. (Law of Ukraine)

7. Practical conclusion

For most FOPs in Ukraine, the law does not require maintaining a universal paper archive for all documents. The law requires something else: that documents exist, are properly executed, stored for the established period, and confirm operations, activity rights, goods movement, settlements, and labor relations. An electronic format is sufficient for this in many cases. Paper is needed not "by default for every FOP", but where a specific activity regime strictly requires it. (Law of Ukraine)

The position of the Supreme Court in case No. 922/2115/19 is indicative: to confirm a business transaction, what matters is not the formal presence of paper, but proper primary documents and the reality of the transaction itself. That is, the entrepreneur loses not because the document is electronic, but when there is no proper proof of the transaction itself or it is improperly executed. (Supreme Court of Ukraine)
