E-signature or QES?

For a PDF, choose the Tvarka e-signature or a qualified electronic signature (QES). If the recipient requires QES, choose it before sending invitations. ADOC and ASiC-E use qualified signatures.

1. Prepare the invitation

Open the final PDF and invite external signers, specifying their email, language and deadline. For an e-signature, you can set an access code or require SMS confirmation when enabled for your workspace. Share the access code separately from the invitation link.

2. Read and confirm

The recipient opens their personal email link without a Tvarka account. If requested, they enter the access or SMS code, read the document, type their name or draw their signature, and confirm consent. They can decline to sign; an expired link no longer permits signing.

When can I switch to QES?

Before anyone signs in this signing round, the sender can switch the entire document to qualified signing. The old e-signature invitations are cancelled and new QES invitations are sent. Access and SMS codes do not carry over. Once someone signs, the signature level of this round cannot be changed.

3. Keep the result

Once all invitees sign and the document completes, you receive the PDF and a signing summary with names, times, methods and a verification code. The summary can be part of the PDF or a separate file when the original is already signed or restricts changes. Keep all delivered files. A timestamp does not make the Tvarka e-signature a qualified signature.

4. Check the exact file

Open the verification link in the summary or enter its TVK code at /v/. The page shows signers, times, signature level and completion status. Drop your file onto the page: its SHA-256 is calculated in your browser and only the hash is sent. The file is not uploaded. A matching code or name alone does not establish that your file is the same one.

Team and external e-signatures

Your own team members sign with the Tvarka e-signature free of charge. This is not a qualified electronic signature (QES).

When people outside your team sign, the sender pays €0.29 + VAT per completed document, regardless of the number of signers. A declined or expired document does not incur this document fee.

An optional SMS code, if enabled by the sender, costs €0.10 + VAT per SMS sent. SMS already sent remain chargeable even if the document is not completed. An access code or SMS code does not make the signature qualified.

QES is billed for each successful signature by a person; external e-signing is billed once per completed document. For example, three external e-signatures on one document cost €0.29 + VAT in total, with SMS extra.

Who pays for signing?

The invitation sender pays for their organisation's use. An external signer uses their personal link without a paid Tvarka account. Team membership is unlimited, with no per-seat fee. Paid QES, completed external e-signature documents and optional SMS are charged separately.
