Electronic document exchange in Uzbekistan: how to switch

By Shohista Azizova · · 9 min read

Electronic document exchange in Uzbekistan means sending and receiving primary business documents in digital form, where a digital signature does the job that paper and a company stamp used to do. Invoices have already been moved to electronic form by law; everything else a company converts at its own discretion. The starting kit is short: a digital signature for the director, a chosen operator and clean reference data.

Key takeaways

  • The electronic form of the invoice has been mandatory for all business entities since 1 January 2020.
  • A digital signature is what gives an electronic document its legal weight: a signed file is equivalent to a paper one.
  • A signature key certificate is valid for no more than 24 months, so its renewal date belongs in the calendar.
  • Certificates of completion, contracts and powers of attorney move to digital form by agreement, not by obligation.
  • The real gain comes from integration: the document is built from an event in the accounting system and its status returns to CRM.

What electronic document exchange is and which documents go through it

It is the exchange of documents in digital form in which a signed file carries the same legal weight as a paper original. The Law on Electronic Document Circulation No. 611-II of 29 April 2004 defines an electronic document as information recorded in electronic form and confirmed by a digital signature, and states directly that such a document is equivalent to one on paper.

That leads to a distinction worth settling early: an electronic document is not a scan and not a PDF in an email. A scanned certificate of completion is a copy of the paper original, while an electronic document exists only in signed form and is verified by its signature rather than by a stamp.

Every one of these documents lives inside the operator's system: the sender signs, the recipient accepts or rejects, and both sides see the same version with the same signing date. The "we sent it, you never received it" argument moves out of email and into the system log.

What the law requires and what the company decides for itself

What became mandatory in Uzbekistan is the electronic form of the invoice, not the whole document flow. Cabinet of Ministers Resolution No. 522 of 25 June 2019 introduced electronic invoices on a voluntary basis from 1 July 2019 and on a mandatory basis for all business entities from 1 January 2020. The same resolution designated the authorised roaming operator through which electronic invoices are transferred between operators and stored.

Receipt for an individual customerA separate regimeResolution No. 943: online cash register or virtual cash register

Hence a common planning mistake: a company decides it has "moved to electronic documents" as soon as it can issue electronic invoices. In practice closing documents, contracts and powers of attorney still travel by courier, accounting still chases signatures, and half of the gain is lost.

Where the transition starts: five steps

The transition starts with signatures and reference data rather than with the choice of a service: without them any system will run idle.

  1. Obtain digital signatures. The director needs one first, then the accountant and everyone who signs shipping documents.
  2. Clean up the product and service catalogue. Names, units of measurement and codes must match between accounting and documents, otherwise every invoice will be corrected by hand.
  3. Choose an operator and set up the company, its employees and their access rights in the operator's system.
  4. Agree with counterparties. A document only works when the other side signs it electronically too.
  5. Write down the rules. Who signs, how quickly incoming documents are accepted, and what happens when a document is rejected.

The most underrated item is the second one. Catalogues usually accumulate for years, and "Service", "Services 1" and "Work under contract" end up living side by side. Until that is sorted out, automated exchange runs into manual corrections every day, and the team concludes that "the system does not work".

Tip Start with a single flow — for example, outgoing invoices to regular customers only. You will debug the catalogue and the rules on a predictable stream, and add certificates, powers of attorney and incoming documents afterwards.

How to obtain a digital signature and how long it lasts

Registration of digital signatures and issuance of key certificates is handled by the Scientific and Information Centre for New Technologies under the Tax Committee, through the Public Service Centres. According to the service description on the government portal, only heads of legal entities may apply online, the applicant goes through biometric identification, and the state fee for a legal entity is 10% of the base calculation value.

The signature has a limited life. The Law on Electronic Digital Signature No. ZRU-793 of 12 October 2022 sets the validity of a key certificate at no more than twenty-four months, with renewal permitted no more than twice. That law entered into force on 14 January 2023 and replaced the earlier Law No. 562-II of 2003.

The practical rule for a company is simple: keep the signature's expiry in the calendar next to domain and TLS certificate renewals. An expired certificate stops invoicing the same day, and restoring it takes time that is rarely available at the end of a quarter.

How to choose an operator

An operator is chosen by how well it connects to your accounting system and which documents it supports beyond invoices, not by its interface. The accountant will see the interface; the whole company will live with the data exchange.

The last point is checked least often, and it is exactly what determines the cost of leaving. Ask for an export in machine-readable form together with the signature files, not an archive of PDFs: a signature cannot be verified against that kind of archive later.

How to connect the exchange to 1C, CRM and the warehouse

The connection runs through the operator's API: the document is assembled in the system where the event happened, goes out for signature automatically, and its status comes back to the order record. A shipment from the warehouse, a closed deal in CRM, a certificate for a project — each of these events already holds everything the document needs, so there is no reason to type it a second time.

The exchange is designed around four questions: what the source of the data is, which key ties the document to the order, where the statuses come back to, and what happens on an error. Without an answer to the last one, the integration falls apart in its second week.

If the company already runs an ERP, the document is built there and the exchange becomes the sending channel. An ERP ties the warehouse, purchasing and sales into one loop, and the invoice is the last step of that loop rather than separate work for the accountant. The same principle applies to a B2B portal for dealers: the portal shows the client the document status, but it neither prints forms nor replaces the invoicing system.

For incoming documents, recognition helps. Electronic invoices do not need to be recognised — they arrive from the operator already structured. Paper certificates and bills from suppliers who have not switched yet are worth running through AI-based document processing and storing in the same loop, so that accounting has one inbox instead of two.

Invoices, fiscal receipts and primary documents: what does not replace what

An electronic invoice covers settlements between organisations, but it does not replace the receipt given to an individual customer. Settlements with the public follow a separate regime: Cabinet of Ministers Resolution No. 943 of 23 November 2019 established the use of online cash registers and the virtual cash register system.

For an online store, or any platform that takes card payments, this means two loops. One issues a fiscal receipt to an individual, the other issues an invoice to a company. If both flows are kept in one order table, month-end brings discrepancies that have to be untangled by hand.

Important An electronic document is valid exactly as long as its signature can be verified. Storage is therefore part of the task: you need not only a PDF for people to read, but also the original signed file against which the signature can still be checked years later.

Where that archive physically sits is not purely a technical question. We covered it in the piece on choosing between cloud and an on-premise server in Uzbekistan: the law requires part of the data to stay inside the country, and document storage is designed with that in mind rather than after launch.

Common mistakes during the switch

What usually gets in the way is not technology but unreconciled catalogues and missing rules.

How we connect document exchange to accounting systems

Syntra Systems is an IT company from Tashkent and an IT Park resident. We are not an operator and we do not replace one: our part starts where the document has to be tied to accounting, the warehouse, CRM and the website, so that the same data is not typed twice.

The work usually goes like this: we sort out the catalogues and the current path of the document, describe the exchange for each document type, connect the operator's API, return statuses to the order record and set up alerts for exchange errors. On the ERP and integrations page the closest service is connecting systems you already run, from $4,000.

Frequently asked questions

Does a sole proprietor need electronic document exchange?

Resolution No. 522 applies the electronic invoice requirement to all business entities, not only to limited liability companies. Other documents a sole proprietor converts at their own discretion: the more regular counterparties there are, the faster it pays off.

Can you work with a counterparty that is not connected to an operator?

Not for invoices — the receiving side gets them in the electronic system as well. For other documents you can: a certificate or a contract with such a counterparty stays on paper until they connect. That is why a transition starts with a list of counterparties and a check of who is already in the system.

What do you do if a counterparty rejects an invoice?

A rejected document does not disappear: it stays visible in the operator’s system along with the reason for rejection. From there your internal rules take over — who handles rejections, within what time, and who reissues the corrected document. Without such a rule, rejected invoices pile up until the end of the quarter.

Does a scan of a signed contract count as an electronic document?

No. Law No. 611-II defines an electronic document as information in electronic form confirmed by a digital signature. A scan is a copy of the paper original, and its legal weight comes from that paper document, not from the file.

Can an individual’s digital signature be used to sign company documents?

These are different keys with different purposes. Company documents are signed with the legal entity’s signature, while an individual’s key is used for personal applications and services. The certificate states who it was issued to and what it may be used for, and verification takes that into account.

Do you have to buy a ready-made 1C module, or is the API enough?

Both routes work. A ready module starts faster and suits accounting kept in a standard configuration without customisation. API integration is needed when documents originate outside 1C — in CRM, in the warehouse or on the website — and statuses have to come back to those systems.

What happens to the document archive if you change operators?

This is worth checking before you connect rather than after. Ask the operator in what form the archive is handed over: you need the original signed files together with their signatures, not only PDFs. A signature cannot be verified against an archive of PDFs alone.
